We know that ∠E = ∠F because of the vertical angle theorem.
Using substitution we get 8x + 8 = 2x + 38
Solve for x.
8x + 8 = 2x + 38
8x = 2x = 30 <-- Subtract 8 from each side
6x = 30 <-- Subtract 2x from each side
x = 5 <-- Divide both sides by 6
So, x is equal to 5.
Answer:
10
Step-by-step explanation:
c^2 = a^2 + b^2
c^2 = 8^2 + 6^2
c^2 = 64 + 36
c^2 = 100
c = 10
8x - (5x + 4) ≥ -31
8x -5x - 4 ≥ -31
3x ≥ -31 + 4
3x ≥ -27
x ≥ - 9
Answer: a numbe line with a circle on - 9 and shading to the left.
Because that drawing represents the number that are less or equel than -9 and the answer is the numbers greater or equal than -9.
