Answer:

26/x = 13

x = 2

Step-by-step explanation:

2(x - 4) = 4

2x - 8 = 4

2x = 4 + 8

2x = 12

x = 12/2

x = 6

26/x = 13

Cross product

26 = x * 13

26 = 13x

x = 26/13

x = 2

- 3.8x = -7.4

x = -7.4 / -3.8

x = 1.95

4(x - 1) - 3(x - 2) = -8

4x - 4 - 3x + 6 = -8

x + 2 = -8

x = -8 - 2

x = -10

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
