Answer:
109
Step-by-step explanation:
9 + |-78| - (-22)
Apply the absolute value which states |-x| = x.
9 + 78 - (-22)
Apply the rule that states x - (-y) = x + y.
9 + 78 + 22
Add 9 and 78.
87 + 22
Add 87 and 22.
109.
Answer:
<h2>
k = 3</h2>
Step-by-step explanation:
The vertex is (d, e)
for quadratic function: f(x) = ax² + bx + c we have:
d = -b/a and d = (x₁ + x₂)/2
a = 1, b = k, x₁ = -4, x₂=-2
so:
d = -b/a = -k/1 = -k and d = (x₁ + x₂)/2 = (-4-2)/2 = -3
-k = -3
k = 3
11+7=18
11*7=77
i hope that my answer helps
