Answer:
-1/2
Step-by-step explanation:
You find the change in the y coordinates. 6 -> 5 is -1. Now the same for the x. 2 -> 4 is +2. now place them in a fraction with the y/x -1/2. if both were negative then you would just cancel out the negatives.
CAN SOMEONE HELP ME PLS AAAAA? Jason purchased a cell phone on sale for $100. He will pay a $25 monthly service for the line. Write an equation for this scenario. Is this a proportional relationship?
Answer:
Step-by-step explanation:
y = 25x +100
y- is the total money spent on the phone
x-is the number of months you had service
the relationship between x and y is proportional ( if x grows, y grows)
For example: after 2 months you would had payed $100 for the phone + the $25 each of the 2 months. y= 25*2 +100 = $150
Subtract 7 from the product 3 times f
Answer:
3*f-7
Step-by-step explanation:
OK; "subtract from" means to do the "from" first and then subtract the number off of the "from." In this case, the "from" is 3*f. Then, subtrat seven. That gives you 3*f-7. No need for parenthesis because of PEMDAS.

Write an equation to represent the problem, be sure to explain the meaning of any variables you use, Jaden dog was 5 and a half inches tall when it was a puppy, now her dog is 14 and a half inches taller than that, how tall is the dog now
Answer:
The dog is 20 inches tall now.
Step-by-step explanation:
Given that:
Height of dog when it was a puppy = [tex]5\frac{1}{2}[/tex] inches
Height of dos now = [tex]14\frac{1}{2}[/tex] than previous height
It means that we will add this height in the height of dog when it was a puppy.
Height of dog now = [tex]5\frac{1}{2}+14\frac{1}{2}[/tex]
Height of dog = [tex]\frac{11}{2}+\frac{29}{2}=\frac{11+29}{2}=\frac{40}{2}[/tex]
Height of dog = 20 inches
Hence,
The dog is 20 inches tall now.

the vertex of y=(x-4)(x+2)
Answer:
(1,-9)
Step-by-step explanation:
Answer:
vertex = (1, - 9 )
Step-by-step explanation:
The vertex is located on the axis of symmetry
The axis of symmetry is at the midpoint of the zeros
Find the zeros by letting y = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 4 = 0 ⇒ x = 4
Then equation of axis of symmetry/ x- coordinate of vertex is
x = [tex]\frac{-2+4}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
Substitute x = 1 into the equation for corresponding value of y
y = (1 - 4)(1 + 2) = (- 3)(3) = - 9
vertex = (1. - 9 )
Mrs.Salcido cut a small birthday cake into 6 equal pieces for 6 children. One child was not hungry. So she gave the birthday boy the extra piece. How much cake did each of the five children recieved.
Answer: The birthday boy got [tex]\dfrac13[/tex] of cake and rest each of the 4 children got [tex]\dfrac16[/tex] of cake.
Step-by-step explanation:
1 cake is divided into 6 pieces.
1 piece = [tex]\dfrac16[/tex]
Birthday boy got 2 pieces.
Part of cake he has = [tex]2\times\dfrac16=\dfrac26=\dfrac13[/tex] [divide numerator and denominator by 2]
So, birthday boy got [tex]\dfrac13[/tex] of cake and rest each of the 4 children got [tex]\dfrac16[/tex] of cake.

4 + 3a +8 < 16
3a - 2a +1>2
5a - 4a + 6 < 8
Answer:
Hi! I hope this is correct please inform me if this is incorrect :)
a = 1 will have.
2a + 3 < 9 - 3a.
2a + 3 > 10 -3a.
3a - 2a + 1>2.
a = 2 will have
ANY others I did not include in a = 1 :)
Please once again tell me if this is incorrect.
Step-by-step explanation:
Inequality (1), (4) and (7) are true for a=1 and inequality (2), (3) and (5) are true for a=2.
We need to determine which inequalities are true for a=1 and a=2.
What are inequalities?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Now, put a=1 inequalities and check.
1) 2(1) + 3 < 9 - 3(1)⇒5<6
2) 14 + 5(1) < 12(1) + 1⇒19>13
3) 2(1) + 3 > 10 - 3(1)⇒5<7
4) 4 + 3(1) +8 < 16⇒15<16
5) 3(1)- 2(1)+1>2⇒2=2
6) 5(1)- 4(1)+ 6 < 8⇒7<8
So, inequality (1), (4) and (7) are true for a=1.
1) 2(2) + 3 < 9 - 3(2)⇒7>6
2) 14 + 5(2) < 12(2) + 1⇒24<25
3) 2(2) + 3 > 10 - 3(2)⇒7>4
4) 4 + 3(2) +8 < 16⇒18>16
5) 3(2)- 2(2)+1>2⇒3>2
6) 5(2)- 4(2)+ 6 < 8⇒8=8
So, inequality (2), (3) and (5) are true for a=2.
Therefore, inequality (1), (4) and (7) are true for a=1 and inequality (2), (3) and (5) are true for a=2.

Malia is observing the velocity of a cyclist at different times. After two hours, the velocity of the cyclist is 15 km/h. After five hours, the velocity of the cyclist is 12 km/h.
Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times. Show your work and define the variables used. (5 points)
Part B: How can you graph the equations obtained in Part A for the first 12 hours? (5 points)
PLEASE DON'T PUT RANDOM ANSWERS HERE I WILL REPORT YOU
We must to remember what is the standard form of equation of straight line. It looks like that:
Ax+By+C=0. A,B and C it's coefcients; x and y - it's variables.A and B must not be equal to zero at same time.This condition can be writen like this: (A^2+B^2) not equal to zero.
We know that x=2 ("after two hours") and y=15 ("velocity of the cyclist is 15 km/h")
AND
x=5 ("after five hours") and y=12 ("velocity of the cyclist is 12 km/h").
Lets look at standart form and give the values on variables.1. 2A+15B+C=0
2. 5A+12B+C=0and it is system.let's subtract the bottom equation from the top -3A+3B=03A=3BA=B.So we can choose any value for A and B, just A=B.I choose for A=B=1.Our equation takes the formx+y+C=0
x+y=-C
and if we giving the value to variables, we can find coefficients "C".
5+12=-CC=-17.
Standart form is:x+y-17=0. ---- answer for Part A.
and the graph of this function is a straight line.For find the answer to Part B, we need to prolong our straight line into the perpendicular vertical line wich contain x=12.
In the point of the intersection of the lines, you must to turn at right angle to axis OY and to come at the value in the axis OY, it's will be the velocity after 12 hours

dan pays £714.73 a year on his car insurance
the insurance company reduces the price by 4.1%
how much does the insurance cost now?
give your answer rounded to 2DP
Answer:
The Current Insurance cost = $685.43
Step-by-step explanation:
Given that Dan pays £714.73 a year on his car insurance.
Reduced Percentage = 4.1%
so
Reduced Amount = 4.1% × 714.73
= [4.1 / 100] × [714.73]
= 0.041 × 714.73
= $29.30
The current cost can be calculated by subtracting the reduced amount of 29.30 from 714.73.
so
Current Insurance cost = 714.73 - 29.30
= $685.43
Therefore, the Current Insurance cost = $685.43

Answer:
a) 3, 8, 63, 3968
b) some other kind
c) continue to evaluate terms sequentially
Step-by-step explanation:
a) To find the first four terms, use the recurrence relation:
t(1) = 3 . . . given
t(2) = t(1)^2 - 1 = 3^2 -1 = 9 -1 = 8
t(3) = 8^2 -1 = 64 -1 = 63
t(4) = 63^2 -1 = 3969 -1 = 3968
The first 4 terms are 3, 8, 63, 3968.

Point A is located at –24 and point C is located at 36 on the number line below.
Which value would represent point B, halfway between point A and point C?
Answer:
Please check the explanation.
Step-by-step explanation:
A number line is a horizontal line with negative values on the left-hand side of an arbitrary number 0 and positive values on the right-hand side of 0.
The location of point A on a number line = -24
The location of point C on a number line = 36
The distance between -24 and 36 can be simply calculated by counting the number of units between.
Starting from -24, we would need to move 24 units on the right side to reach the 0 and 36 units right to reach 36.
So, the total units will be: 24+36 = 60
A second simple method to calculate the distance between point A and point C is:
Distance between A and C = location of C - location of A
= 36 - (-24)
= 36+24
= 60 units
Thus, the distance between A and C is 60 units.
Now, point B is located halfway between point A and point C.
Thus,
The point B must be 30 units before (30 units on the left side) of the point C. In other words, point B must be 30 units after (30 units on the right side) of point A.i.e.
The location of point B = The location of point C - 30
= 36 - 30
= 6
Thus, point B is located at 6.
Verification:
The location of point B = The location of point A + 30
= -24 + 30
= 6
Thus, point B is located at 6.
Thus, it is verified that point B, halfway between point A and point C.
Hence,
'6' is the value of point B halfway between point A and point C.
Find the degree of the term -5x to the power of 4
Answer:
4 or -625x^4 (Just in case I misunderstood)
Step-by-step explanation:
The degree is always the power of something. Since -5x has a power of 4, its degree is 4.
Just in case I misunderstood the question, I will solve it another way that I think you meant. (-5x)^4 is -5^4 times x^4.
-625 times x^4 is -625x^4.

x + 4y = 13
What is the value of x?
Answer:
13-4y
Step-by-step explanation:
Without a second equation it is impossible to give a numerical value for x, but x can be expressed in terms of y.
This equation is called a "literal equation" since there are more than one variable, but only one equation (it is not a system of equations).
Therefore, solve for x by subtracting 4y from both sides:
x+4y=13
-4y -4y
x=13-4y
Answer:
Hi! The correct answer is x=13-4y!
Step-by-step explanation:
~Subtract 4y from both sides of the equation~
