Domain: {-4,0,8}
Range: {1,5,10}
Answer:
(2a - )(2a + )
Step-by-step explanation:
4a² - ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
4a² -
= (2a)² - ( )²
= (2a - )(2a + )
Answer:
D. y = 4x + 9
Step-by-step explanation:
a line that passes through the point (-2, 1) and has a slope of 4
y = 4x + b
b = y - 4x
b = 1 - 4(-2)
b = 1 + 8
b = 9
So equation
y = 4x + 9
Answer:
7! = 5040
Step-by-step explanation:
7! is a factorial expression that can be solved as follows:
7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040
