Answer:
step 1. you see in the problem x = 6y + 9 substitue the equation for the x variable in the first equation. so it will be 2(6y+9) - 12y = 7
step 2. solve for y. butttt in this case it looks like it can't be solved .
Step-by-step explanation:
option 3. in the steps i provided substituted x for x equals 6y + 9 which leads you to solve y. if you want you can rearrange 2x-12y=7 to solve for y so it would be 7-2x/-12 = 7
I don’t know if its just me but i can’t see the picture, im really sorry :/
Volume is in cubic units, meaning the volume ix raised to the 3rd power.
If the cube is scaled by 5, then the volume is scaled by 5^3.
5^3 = 5*5*5 = 125
The new volume would be the original volume multiplied by the total increase:
64 x 125 = 8,000 cubic meters.
Slope= (y2-y1)/(x2-x1)
slope=(1-4)/(4-1)
slope=(-3)/(3)
slope=-1
Slope is also named m
Now you use the point slope form to find the whole equation.
y-y1=slope(x-x1)
y-1=-1(x-4)
y-1=-1x+4
y=-1x+5
