describe in words how to graph the line y=3
What is the equation of the line that passes through the point (8,-8 and has a slope of -1/4
Answer:
The answer is
[tex] \huge y = - \frac{1}{4} x - 6[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is ( 8 , - 8) and slope -1/4
We have
[tex]y + 8 = - \frac{1}{4} (x - 8) \\ y + 8 = - \frac{1}{4} x + 2 \\ y = - \frac{1}{4} x + 2 - 8[/tex]
We have the final answer as
[tex]y = - \frac{1}{4} x - 6 \\ [/tex]

At the movies, children's tickets are $6 each and adults' tickets are $10 each. Shandra buys 14 tickets. Let a be the number of adults going to the movies. Enter an algebraic expression in the box to represent the total price Shandra pays. Do not include the dollar sign in your answer.
Answer:
y=6x+10aStep-by-step explanation:
let the number of children be x
and the number of adults be a
let the total price be y
given that children tickets are $6 each
also, an adult ticket is $10
x+a=14-------1
y=6x+10a----2
Therefore the expression for the total price can be expressed as
y=6x+10aAnswer:

You had 23 dollars to spend on 4 avocados. They were very green. After buying them you had 11 dollars. How much did each avocado cost?
Answer:
the avacodos cost 12
Step-by-step explanation: if you sutract 23 by 11 you get 12 and if you chek you ansewer by adding 12+11=23
The answer is $3.
Step-by-step explanation:
1. Let's subtract 11 ($ remaining) from 23 ($ we had originally) to see how much we spent in total. (23 - 11 = 12)
2. Divide 12 ($ spent) and 4 (Avocados bought) to find out how much each avocado cost. (12 ÷ 4 = 3)

3(x+1)+11 = -2(x+13)
Thank you for the help
Answer:
x = -8
Step-by-step explanation:
3(x+1)+11=-2(x+13)
3x+3+11=-2x-26
3x+14=-2x-26
5x=-40
x=-8
Answer:
x = -8
Step-by-step explanation:
Step 1: Write equation
3(x + 1) + 11 = -2(x + 13)
Step 2: Solve for x
Distribute: 3x + 3 + 11 = -2x - 26Combine like terms: 3x + 14 = -2x - 26Add 2x to both sides: 5x + 14 = -26Subtract 14 on both sides: 5x = -40Divide both sides by 5: x = -8Step 3: Check
Plug in x to verify it's a solution.
3(-8 + 1) + 11 = -2(-8 + 13)
3(-7) + 11 = -2(5)
-21 + 11 = -10
-10 = -10

Maggie's brother is 6 years younger than four times her age. The sum of their ages is 69.
How old is Maggie?
Answer:
15
Step-by-step explanation:
If Maggies age is, for example, x, we can say that her brothers age is 4x-6. We know from the problem that Maggies age (x) plus her bothers age, (4x-6) is 69. So,
4x-6+x=69
5x-6=69
5x=75
x=15
So, Maggie is 15.
Answer: Maggie is 15 years old
Step-by-step explanation:
69 = (4m - 6) + m --- get an equation
69 - m = 4m - 6 --- lets subtract m from both sides first
75 - m = 4m --- add 6 on both sides
75 = 5m --- add m on both sides
15 = m --- divide by 5 on both sides
m = 15, so Maggie is 15 years old
Let's check:
69 = (4(15)-6) +15
69 = (60 - 6) + 15
69 = 54 + 15
69 = 69

A taxi cab company charges a flat amount of $5.00 plus a rate of $3.00 per mile traveled, what is the total number of miles traveled if the fare was $41.00
Answer:
Step-by-step explanation:
Amount charged = $5.00
Amount charged for per mile = $3.00
Miles traveled =
Total amount charged = $41.00
Total amount = $3 per mile - $5
41-5 = 35
Miles traveled= $35 ÷ $3
35÷3 = 11.66
Miles traveled = 11/11.66

In class of 60 boys, there are 45 boys who play card and 30 boys who play carom. How many play both games
Answer:
the answer is 40 boys
Step-by-step explanation:
Let's say there are x boys who play both cards and carrom.
We setup up an equation that involved all information given and x.
Boys who only play cards = 45-x
Boys who only play carrom = 20-x
Boys who play both = x
Add there together and you should get 60, which is the total number of students in the class.
(45-x)+(20-x)+x=60
65-x=60
x=5
Boys who only play cards=45-x=45–5=40
hope it helps you
Answer:
there are 15 boys who can play both games in the class.

Help Please!!!What is the correct slope-intercept form of the equation y+4=2(x−3)?
1. y=2x−3
2. y=2x−6
3. y=2x−10
4. 1/2y=2x−5
Explain Your Answer
Answer:
third option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
y + 4 = 2(x - 3) ← distribute parenthesis
y + 4 = 2x - 6 ( subtract 4 from both sides )
y = 2x - 10 ← in slope- intercept form
The slope- intercept form of the equation y+4=2(x−3) is y = 2x - 10 .
What is slope?Numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it.
Given:
The equation is
y+4=2(x−3)
We have to find the correct slope-intercept form of the equation.
The equation of a line in slope- intercept form is
y = mx + c
According to given question we have,
y + 4 = 2(x - 3)
Distribute parenthesis we get,
y + 4 = 2x - 6
subtract 4 from both sides we get,
y = 2x - 10
Therefore , the slope- intercept form of the equation y+4=2(x−3) is y = 2x - 10 .

1. Select all of the true statements.
A. Pi is the area of a circle of radius 1.
B. Pi is the area of a circle of diameter 1.
C. Pi is the circumference of a circle of radius 1.
D. Pi is the circumference of a circle of diameter 1.
E. Pi is the constant of proportionality relating the diameter of a circle to its circumference.
F. Pi is the constant of proportionality relating the radius of a circle to its area.
We want to see which of the given statements about the number pi are true.
The correct options are: a, d, and e.
First, let's talk a little bit about the number pi.
The irrational number pi is defined as the quotient between a circle's circumference and its diameter.
So if we know that a circle has a diameter D, the circumference of that circle is given by:
C = pi*D
Now let's analyze each option to see which ones are true.
a) "Pi is the area of a circle of radius 1."
The area of a circle of radius R is given by:
A = pi*R^2
So if the radius of this circle is R = 1. we have:
A = pi*1^2 = pi
So the area of this circle is pi, thus the statement is true.
b) "Pi is the area of a circle of diameter 1."
The diameter is twice the radius, so the radius of this circle is 0.5, we know that pi is the area of a circle of radius 1, not a circle of radius 0.5, so this is false.
c) "Pi is the circumference of a circle of radius 1."
The circumference of a circle of radius R is given by:
C = pi*2*R
If the radius is equal to 1 we have R = 1, then:
C = pi*2*1 = 2*pi
The circumference of this circle is 2*pi, not pi, so this is false.
d) "Pi is the circumference of a circle of diameter 1."
We know that the circumference of a circle of diameter D is:
C = pi*D
So if D = 1, we have:
C = pi*1 = pi
So the circumference of this circle is equal to pi, thus, this statement is true.
e) "Pi is the constant of proportionality relating the diameter of a circle to its circumference."
A proportional relation is:
y = k*x
where k is the constant of proportionality.
The relation between the circumference is given by:
C = pi*D
So yes, pi is the constant of proportionality, this is true.
F) "Pi is the constant of proportionality relating the radius of a circle to its area."
The area equation is:
A = pi*R^2
note that the radius is squared, so this is not a proportional relation, then the statement is false.
Finally, we can conclude that the true statements are:
a, d, e.
