Answer:
B, y = 4x + 1
Step-by-step explanation:
to get it into y- intercept form we need to write it in the form y = mx + b
-8x = 2 - 2y, move 2y to the other side and -8x to the other side they both become positive.
2y = 8x + 2, dividing each by 2
yields y = 4x + 1
Hope this helps
To determine the total time it needs for the two painters to completely paint the whole wall space, we need to relate the total area of the wall to be painted and the time they need. So, base from the problem, the relation would just be a linear function. We do as follows:
let A = total area of the wall space
t = total time they both need
Painter 1 = <span>190 square feet per hour
Painter 2 = </span><span>130 square feet per hour
total area = 1200 ft^2 (3) = 3600 ft^2
The function would be:
A = 190t + 130t
3600 = 190t + 130t
3600 = 320t
t = 11.25 hrs

Answer:
A) 100pi cm^2
Step-by-step explanation:
area of a circle: r^2pi
radius=1/2diameter
diameter=20 cm
radius=10cm
10^2pi cm
100pi cm^2
You would need 27 more dollars because f(x)=7x+2 plug in the 5 in x’s spot and you get 37 and so subtract it from 10 to get 27
You can use an app called photomath to solve it
