Answer:
y=-3x-2
Step-by-step explanation:
Equation of a line is y=mx+b, where m is the slope given, -3.
Y=-3x+b
To find b, sub in the points (-3,7) for x and y in the equation
7=-3(-3)+b
7=9+b
-2=b
If y=4x+2 and x=1, we can get 4*1+2=6 for y, resulting in 1*6+1/6=2+z. Subtracting 2 from both sides, we get 4+1/6=z
The astronomy club will have to wash 66 cars because 327.19 divided by 5.00 is 65.438 and rounded would be 66 cars that need to be washed
Answer:
So, what you want to do first is add the height together.
5+5+5+5= 5*4=20
Then use the formula for finding the surface area of a rectangular prism.
A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
In other words A= 2(12*10) + 2(10*20) + 2(20*12)
Simplify from there.
A= 2(120) + 2(200) + 2(240)
A= 240 + 400 + 480
A= 1,220
