Answer:

A. h = 4

B. g = 15

C. b = -6

D. b = 15

Step-by-step explanation:

A.  9h + 8 - 12 = -40

         9h - 4 = -40

              + 4    + 4

        9h = -36

       \frac{9h}{9} = \frac{-36}{9}

       h = -4

B.  9 + 6g + 1 = 100

        10 + 6g = 100

      - 10            - 10

            6g = 90

            \frac{6g}{6} = \frac{90}{6}

            g = 15

C.  -45 = 28 - 13 + 10b

    -45 = 15 + 10b

    - 15  - 15

    -60 = 10b

    \frac{-60}{10} = \frac{10b}{10}

    b = -6

D.  37 = 11 +3b - 19

     37 = 3b - 8

    + 8         + 8

     45 = 3b

     \frac{45}{3} = \frac{3b}{3}

     15 = b

What is the solution to the linear equation?<br><br> –12 + 3b – 1 = –5 – b
marysya [2.9K]
-12+3b-1=-5-b
Combine like terms to get:
3b-13=-5-b
Add 13 to both sides:
3b= 8-b
Add b to both sides:
4b=8
Divide both sides by 4:
4b/4=8/4
b=2

Final answer
b=2

I need algebra help.....
Lubov Fominskaja [6]

Answer:

y=4(3)^x

Step-by-step explanation:

From the table given in the question,

x            y              Difference                  Ratio

1            12                     -                             -

2           36              36-12 = 24              \frac{36}{12}=3

3          108            108-36 = 72             \frac{108}{36}=3

4          324            324-108 = 216        \frac{324}{108}=3

5          972            972-324 = 648      \frac{648}{216}=3

There is a common ratio of 3 in each successive term.

Therefore, data given in the table will represent an exponential function.

y=a(b)^x

For a point (1, 12),

12=a(b)^1

ab=12 ------(1)

For another point of the table (2,36),

36=a(b)^2

ab^2=36 --------(2)

Equation (2) divided by equation (1)

\frac{ab^2}{ab}=\frac{36}{12}

b=3

From equation (1),

3a=12

a=4

Therefore, exponential function will be,

y=4(3)^x
