Answer:
<h2>18x + 30</h2>
Step-by-step explanation:
The distributive property: a(b + c) = ab + ac.
-6(-3x - 5) = (-6)(-3x) + (-6)(-5) = 18x + 30
Answer:
(1.5,2.5)
Step-by-step explanation:
f(x) = 2x^2 - 6x + 7
Take the first derivative and set it equal to 0 (the slope is 0 at the vertex)
f'(x) = 4x -6
0 = 4x - 6
4x = 6
x = 3/2 or 1.5
If x = (3/2), then y = 2(3/2)^2 - 6(3/2) + 7
y = 2(9/4) - 18/2 + 7
y = (9/2) - 2
y = 2.5
See attached graph.

Answer:
28°
Step-by-step explanation:
soln
(x+3)°+(2x+3)°
x°+3°+2x°+3°=90°(beign complementary angles)
3x+6=90°
3x=90°_6
3x=84
x=84/3
x=28°
Answer:
(-3, 5), (1, 4), (-2, 3), and (0, 2).
Step-by-step explanation:
When a function is inverted, the x-values become y-values, and the y-values become x-values.
The ordered pairs for the function are (5, -3), (4, 1), (3, -2), and (2, 0).
After inversion, the ordered pairs will be (-3, 5), (1, 4), (-2, 3), and (0, 2).
Hope this helps!
