X=0 There is no factoring this equation.
Answer:
y=-8
Step-by-step explanation:
From the information given, we know that the slope of the line is 0. Let's make an equation in y=mx+b form with what we know.
y=0x+b
We also have a point on the line, (5, -8). We can plug these two numbers for x and y to find b and complete the equation. -8 goes in as y and 5 goes in as x.
-8=0(5)+b
Now just solve for b.
-8=0+b
b=-8
We now know that b is -8 and can complete the equation.
y=0x-8
y=-8

Answer:
a + b =1
Step-by-step explanation:
Write the given quadratic as x^2 – 1x – 90 = 0. This factors into
(x - 10)(x + 9) = 0, and so the roots/solutions are {-9, 10}.
If we call -9 "a" and 10 "b," then the sum a + b is -9 + 10, or a + b =1.
