Answer:
4
Step-by-step explanation:
80 - 47.08 = 32.92
32.92/8.23 = 4
Answer:
1. x = 36
2. x = -2, x = 5
Step-by-step explanation:
Secant - Secant Power Theorem: 12(12 + x) = 10(18)
144 + x = 180
x = 36
Chord - Chord Power Theorem: (x - 2)(x + 7) = 4(2x - 1)
x^2 + 5x - 14 = 8x - 4
x^2 - 3x - 10 = 0
Factor:
(x + 2)(x - 5) = 0
x = -2, x = 5
Answer:
Step-by-step explanation:
y=ax^2+bx+c
a parabola open down when a is negative
y intercept equal 3 when x=0 then y=c=3
vertical stretch : is a stretch away from the x-axis
the equation is (-0.5x^2+4x+3)
i hope it helps
The answer is B. Because X and Z are considered congruent.
