Answer:
(f⋅g)(x)=8x^2−2x−15
Step-by-step explanation:
To find the expression (f*g)(x), multiply f(x) into g(x) using the distribution property.
(f*g)(x) = (2x - 3)(4x + 5) = 8x² - 12x + 10x - 15 = 8x² - 2x - 15
2-4y. Reorder the terms, then Write the division as a fraction, then Factor the expression, then Reduce the fraction.
Answer:
complementary angles
Step-by-step explanation:
∠1 and ∠2 form a right angle and are complementary, that is they sum to 90°
Answer:
B
Step-by-step explanation:
When reflecting a figure over the x-axis, flip the sign of the y-coordinates for the vertices.
For this figure, trapezoid ABCD, the vertices are:
A (3, -2)
B (7, -2)
C (8, -7)
D (1, -7)
Flipping the signs of the y-coordinates gives us:
A (3, 2)
B (7, 2)
C (8, 7)
D (1, 7)
The only graph that has trapezoid A'B'C'D' with vertices matching these four values is the graph for B, so the answer is B.
