110° because interior angles are half the measure of their arc
Answer:
Step-by-step explanation:
Unless we set x^2 + 8x + 15 equal to zero, we don't have an equation to be solved. I will assume that the problem is actually x^2 + 8x + 15 = 0.
The coefficients of this quadratic are {1, 8, 15}, and so the "discriminant" b^2 - 4ac is (8)^2 - 4(1)(15), or 4. Because the discriminant is positive, we know that there are two real, unequal roots.
Continuing with the quadratic formula and knowing that the discriminant is 4, we get:
-8 ± √4 -8 ± 2
x = ---------------- = --------------- , or x = -2 ± 1: x = -3 and x = -5

Answer:
y=7/4x+15/4
Step-by-step explanation:
y-2=7/4(x+1)
1) Distribute 7/4 to x and 1:
y-2=7/4x+7/4
2) Add 2 to both sides:
y=7/4x+15/4
