Answer: I am pretty sure it is y=-1/4x-8. Hope this helps!

Step-by-step explanation:subtract the 2x from both sides which gives you 8y=-2x-64. Then you want to divide both sides by 8 to get y=-1/4x-8

HURRY NEED HELP NOW 42 POINTS NEED 1 PARAGRAPH FOR EACH QUESTION there are 2 photos I put up and that where the questions are.
Shtirlitz [24]
1. All you have to do to find the area of the figure. IS first find the area of the rectangle. This is easy because all you have to do is base times height. 

22 x 17 =  374

Now to find the area of the triangle all you have to do is  do base times height like a rectangle, but then divide it by 2 afterwords.
19 x 12 = 228 ÷ 2  = 114.

Now add the two area's together:

374 + 114 = 488.

Just do the same with the one below, I've altered the pic a bit to make it easier.

The radius r of a circle is increasing at a rate of 7 centimeters per minute. (a) find the rate of change of the area when r = 1
VikaD [51]
Dr /dt = 7

A = pi r^2

dA / dr = 2pir

dA/dt = dA/dr  * dr/dt = 2pir * 7  = 14pir

when r = 12   rate of change of the area =  14*pi*12  =  168pi

            =  527.79 cm^2 / minute to nearest hundredth
