-0.111c + 1 = 0.889c
Elena-2011 [213]

Answer:

-0.111c + 1 = 0.889c = c=1

Subtract 0.889c from both sides:

−0.111c+1−0.889c=0.889c−0.889c

−c+1=0

Subtract 1 from both sides.:

−c+1−1=0−1

−c=−1

Divide both sides by -1.:

-c/1 = -1/-1

Therefore, your answer is c=1

Which of the following describes the parabola with the equation y = −x2 − 3x + 6?
seropon [69]

Answer:

C) The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).

Step-by-step explanation:

The axis of symmetry is x = − b/2a

= -(-3) / 2(-1)

= 3/(-2)

= -1.5

the vertex => x = -1.5

y= -(-1.5)²-3(-1.5)+6 =

-2.25 +4.5+6= 8.25

If f(x) = 7(x - 2) + 4(x + 1), what is f(2)?<br><br> A. 9 B. 10 C. 12 D. 11
KatRina [158]

Answer:

C) 12

Step-by-step explanation:

These type of questions is basically asking you to replace x with 2. f(x) is the same thing as y = but inside the f(x) is the value of x. So in this case, the numerical value of x is 2. All we need to do is replace x with it's numerical value, 2, and solve the equation.

y=7(2-2) + 4(2+1)\\y=7(0) + 4(3)\\y = 12
