Answer:

I think the answer might be 4x + 9

Step-by-step explanation:

Solve first bracket

( 8x - 1 ) + ( 10 - 4x )

Take away the brackets.

8x - 1 + 10 - 4x

Minus and add like terms

8x - 4x and -1 + 10

4x + 9

Hopefully that helps:)

Mrs. Johnson put 22,250 miles

Viefleur [7K]

The change in quantities can be represented as percentage

The percentage decrease in miles driven is 34.83%

The given parameters are:

$\mathbf{Initial = 22250}$

$\mathbf{Final = 14500}$

The percentage decrease is calculated as:

$\mathbf{\%Decrease = \frac{Final - Initial}{Initial} \times 100\%}$

Substitute known values

$\mathbf{\%Decrease = \frac{14500- 22250}{22250} \times 100\%}$

$\mathbf{\%Decrease = \frac{-7750}{22250} \times 100\%}$

$\mathbf{\%Decrease = \frac{-775000}{22250} \%}$

$\mathbf{\%Decrease = -34.83 \%}$

The negative sign implies that, the change represents a decrement.

Hence, the percentage decrease in miles driven is 34.83%

38. Which equation represents the data in the table?

sergejj [24]

Answer:

C. y = 2x -4

Step-by-step explanation:

We can use the points (0, -4) and (2, 0).

y = mx + b (m is slope, b is y-intercept)

m = delta y / delta x

m = 4 / 2

m = 2

y = 2x + b

We can plug in (2, 0):

0 = 4 + b

b = -4

y = 2x - 4
