What is the rate of change of the function? On a coordinate plane, a line with negative slope goes through points (0, 1) and (1,
negative 1). –2 Negative one-half One-half 2 Mark this and return
1 answer:
Answer:
-2
Step-by-step explanation:
slope: (y² - y¹) / (x² - x¹)
(-1 - 1) / (1 - 0) = -2 / 1 = -2
y = -2x + b
plug in an (x, y) value to find b
1 = -2(0) + b
1 = -2 + b
b = 3
y = -2x + 3
rate of change is -2

Answer: x^2 - 6x - 18
Step-by-step explanation:
(f-g)(x)=f(x)-g(x)=(x^2 - 5x - 24)-(x-8) = x^2 - 5x - 24 - x + 8 = x^2 - 6x - 18
Answer:
p = 144/11
Step-by-step explanation:
12/11 = p/12
~Simplify
12/11 = 1/12p
~Multiply 12 to both sides
144/11 = p
Best of Luck!
Answer:
n >_ 4
Step-by-step explanation:
move 9 to the other side
n >_ 13 - 9
n >_ 4
X=7y-8 because subtract 7y from both sides and then multiply by 1
