car a, car b
Step-by-step explanation:
car a 2x + 2= 4x
car b 3x + 3= 9x
both cars 13x
Answer:
3000 i think that's the answer.
Step-by-step explanation:
Start with

Multiply both sides by 3:

Recall that 21/5=4.2 to claim the correct answer.
We are given equations as

Firstly, we will write in slope intercept form of line
y=mx+b

Subtract both sides by 4x


now, we can divide both sides by a

we can find slope
so, we get

we are given second equation as

Firstly, we will write in slope intercept form of line
y=mx+b
divide both sides by a

we can find slope

we are given both lines are perpendicular
so, the multiplication of their slopes must be -1

we can plug values

now, we can solve for a

Multiply both sides by a


now, we can solve for a
we get
