What is the slope of the line that contains these points

Answer:

y = 7, x = 7

Step-by-step explanation:

11y + 13 = 90

11y = (90 - 13)

11y = 77

y = 7

2x + 6 = 20 (because 20 is half of 40)

2x = (20 - 6)

2x = 14

x=7

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~

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.

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

Answer:

-104

Step-by-step explanation:

5+8=13

2-10=-8

13×-8=-104

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,

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.

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.

__

b) The terms have no common difference or ratio, so the sequence is some other kind of sequence. The ratios of terms form a sequence that is approximately exponential.

__

c) Colin can find the 10th term by evaluating successive terms using the recursion relation. (It is approximately 2.0351×10^230.)

Answer:

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 )

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.

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.

Answer:

A) - 7

slope -intercept form       y =  - 3x - 7

slope m =-3 and y - intercept c = -7

Step-by-step explanation:

Explanation:-

Given that slope 'm' = -3 and point (0,-7)

The equation of the straight line passing through the point and having slope 'm'

y - y₁ = m ( x- x₁)

The equation of the straight line passing through the point ( 0,-7) and slope m = -3

y - (-7) = -3 ( x -0)

y +7 = -3x

3x +y + 7=0

The equation of the line 3x +y + 7=0

Final answer:-                                        

slope -intercept form      y =  - 3x - 7

slope m =-3 and y - intercept c = -7

Also please tell me if I'm wrong or not...

Also also if I'm right can I please have Brainliest?

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

Step-by-step explanation:

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.

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.

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
