Answer:
<h3>
m∠B = 26°</h3>
Step-by-step explanation:
∠A and ∠B being complementary means m∠A + m∠B = 90°
4x + 24 + 3x - 4 = 90
7x + 20 = 90
7x = 70
x = 10
m∠B = (3•10 - 4)° = 26°
Answer:
Step 3, He should not switch the variables, you just don't do that.

Answer:
(x, x2 -2x+8) where −5 ≤ x ≤ 3
Step-by-step explanation:
The given function is f(x)=x2- 2x+ 8
We want to select the option that describes all the solutions to the parabola.
The domain of the parabola is −5 ≤ x ≤ 3.
This means that any x=a on −5 ≤ x ≤ 3 that satisfies (a,f(a)), is a solution.
This can be rewritten as (a,-a2- 2a+ 8)
Therefore for x belonging to −5 ≤ x ≤ 3, all solutions are given by:
(x, x2 -2x+8) where −5 ≤ x ≤ 3.
