Answer:
5 degrees
Step-by-step explanation:
Complementary angles sum up to 90 degrees.
If one angle is 85 degrees, then its complement is (90 - 85), or 5, degrees.
Sum is to add up all the numbers.
-5 + (-9) + 10
= -5 -9 + 10
= -14 + 10
= 10 - 14
= -4.
Answer:
15
Step-by-step explanation:
4g(3)+2[g(2)]²
4((3+4)/√7(3)-5)+2[(2+4)/√7(2)-5]²
=15
y = - 3(x + 1 )² + 2
the equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here vertex = (- 1, 2), hence
y = a(x + 1)² + 2
to find a substitute (1, - 10) into the equation
- 10 = 4a + 2 ⇒ 4a = - 12 ⇒ a = - 3
y = - 3(x + 1)² + 2 ← in vertex form
