Answer:
b=−5x+y
Step-by-step explanation:
Let's solve for b.
y=5x+b
Step 1: Flip the equation.
b+5x=y
Step 2: Add -5x to both sides.
b+5x+−5x=y+−5x
b=−5x+y
100 and 110.
You would have to add 100 to both sides. This is because to complete the square, you need to take half of the x term and square it.
Answer:
-5 and 3
Step-by-step explanation:
you do thos so you can eliminate x and solve for y then substitute the answer to y in one of the equations to solve the equation
