Answer:
<em>y = </em><em> x + 1 </em>
Step-by-step explanation:
If AB ⊥ CD , then ( ) (
) = - 1
y = - x + 3
y - ( - 4) = ( x - 7) ⇔ <em>y = </em>
<em> x + 1 </em>

Answer:
y = 60
Step-by-step explanation:
<h3>Step 1: Make sense of the given</h3>"The ratio of y to x is 3"
This means that,
"The sum of y and x is 80"
This means,
If , then
.
We can plug this into the other equation by substitution:
This simplifies to:
Which we can solve out and get:.
We solved for x, but we need the value of y.
So, we go back to the equation we first derived: "".
And now we substitute the value of x, into this.
By solving this out, we get:
So, the value of y is 60.
