Which of the following is true for f? 3x−1,if−9 A. The domain is −9 < x < −2, −2 < x < 1, and 1 < x < 7.
B. The range is (−26, 1).
C. The function is decreasing over the interval (−2, 1).
D. The rate of change over the interval (−9, 1] is 3.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
