Indira makes a graph to show how many pages of her graphic novel she can
illustrate each day.
a. What is the constant of proportionality for the relationship between
pages and days?
b. Write an equation to show the relationship between pages and days.
Answer:
a). k = 0.75
b). y = 0.75x
Step-by-step explanation:
a). Graph is showing the relation between number of pages (P) illustrated by Indira and number of days taken (D).
P ∝ D
P = kD
Where 'k' is the proportionality constant.
k = [tex]\frac{P}{D}[/tex]
From the graph attached,
For a point with ordered pair (2, 1.5),
k = [tex]\frac{1.5}{2}[/tex]
k = 0.75
b). Equation representing the relation between number of pages and number of days will be,
P = 0.75D
y = 0.75x
Find the height of an equilateral triangle with sides 12 cm long.

A given line has a slope of 7 what would the slope of a line parallel to this line be and why?
Answer:
7
Step-by-step explanation:
A parallel line would have the same slope because it would only have a different y-intercept.
Hope that helps and have a great day!
Write the equation of the line that passes through (3, -2) and is parallel to y= 4x+1
Answer:
it should be y=4x-14
Step-by-step explanation:
since the line is parallel to y=4x+1 than the slope should be the same but the y intercept is different. and so u put the coordinate on a graph and use the slope and coordinate to fine the equation.
Amy sold 10 t-shirts and 2 sweatshirts for $56.
Adam sold 5 t-shirts and 3 sweatshirts for $48.
Write a system of equations to represent this
situation. Let x=cost of a t-shirt and y=cost of a
sweatshirt.
Determine the price of one t-shirt and the price
of one sweatshirt.
Answer:
$3.6 = cost of a t-shirt
$10 = cost of a sweatshirt
Step-by-step explanation:
Given:
10 t-shirts and 2 sweatshirts = $56.
5 t-shirts and 3 sweatshirts = $48.
x = cost of a t-shirt
y = cost of a sweatshirt
Find:
Price
Computation:
10x + 2y = 56.......eq1
5x + 3y = 48........eq2
From 2 x eq2
10x + 6y = 96.........eq3
From eq3 - eq1
4y = 40
y = 10
from eq1
10x + 2(10) = 56
10x + 20 = 56
10x = 36
x = 3.6
$3.6 = cost of a t-shirt
$10 = cost of a sweatshirt

Select all the equations that have the same solution as 2x-5=15.
Step-by-step explanation:
2x =15+5
2x =20
Divide by 2
X=10
Answer:
D, E
Step-by-step explanation:
2x-5=15,x=10
2x=20, x=5
2(x-5)=15, x=25/2
2x-20=0, X=10
4x-10=30, X=10
15=5-2x, X= -5

When as rate, 100 miles in 5 hours would be ????? miles per hour
Answer:
20
Step-by-step explanation:
5 divided by 100 = 20
Answer:
20 miles per hour (20 mi/h)
Step-by-step explanation:
100 miles/5 hours = 20 miles/ 1 hour
(simplify the proportion)
Consider the following formula s=d/t, with
s being the speed, d as the distance, and t as the time.
this is because miles per hour is a measurement of speed.
In this case, 100 miles is the distance. 5 hours is the time, and we are solving for s.
s = 100/5, s = 20/1, s = 20 which is 20. So the rate or the speed is 20 miles per hour.
Anything multiplied or divided by 1 will remain the same.

|8x+3|=12 what’s the answer
Answer:
x= 9/8 , -15/8
Step-by-step explanation:
Answer:
x = 1.125 , x = 9/8
Step-by-step explanation:
|8x+3| = 12
=> 8x + 3 = 12
=> 8x = 12-3 = 9
=> 8x = 9
=> x = 9/8
As 9/8 is a fraction let's make it a decimal.
9/8 * 125/125 (To make it into a power of ten so that we can convert)
=> 1125 / 1000
=> 1.125
