Ax + 3 = 7 - bx .....add bx to both sides
ax + bx + 3 = 7 ...subtract 3 from each side
ax + bx = 7 - 3
ax + bx = 4 ....factor out x
x(a + b) = 4 ...divide both sides by (a + b)
x = 4 / (a + b) <==
Answer:
2x - 4
Step-by-step explanation:
x + 10 + x - 14
2x + 10 - 14
2x - 4

Diameter is a chord of a circle.
The chord of circle F are: AD, BE, and DE.
Among the choices, Choice A and Choice B are the chords of circle F.
I hope this chart is helpful
f(x) = x² - 2x - 7
f(-1), this means that x = -1.
Since you need to find f(-1), substitute/plug in -1 into "x" in the function:
f(x) = x² - 2x - 7 Plug in -1 into "x"
f(-1) = (-1)² - 2(-1) - 7
f(-1) = 1 + 2 - 7
f(-1) = -4 Your answer is B
