X is 90°
A triangles angles add up to 180° so
180 - 47 - 90 = y
180 - 137 = y
y = 43°
Answer:
Step-by-step explanation:
does it have to be right?
y-intercept: (0, 1)
Line of symmetry calculation: x = -b/2a = -(-2)/2(2) = 0.5
Line of symmetry: x = 0.5
Open UP or DOWN: Opens UP
Min or Max: Min
Vertex: (0.5, 0.5)
Domain: {x|x ∈ ℝ}
Range: {y|y ≥ 1/2}
Answer:
f(x) = -8
Step-by-step explanation:
f(x) = x² + 2x – 8
f(x) = (-2)² + 2(-2) – 8
f(x) = (-2)² + 2(-2) – 8
f(x) = 4 + (-4) – 8
f(x) = 4 – 4 – 8
f(x) = 0 – 8
f(x) = -8
I hope this helps
First combine like terms ,
5/5x=9/5x
move the variable which will cancel out because it is the same
5=9 is no solution sorry if i’m wrong lol
