Answer:

19.2 miles

Step-by-step explanation:

If k(x)=2x2-3x, find k(9).

GrogVix [38]

I think the answer is 297.

Explanation:

Replace every x in k(x) with 9

2(9)^2-3(9)
18^2-27
324-27
297
K(9)=297

Find the slope and y-intercept 4x+2y=-6

EleoNora [17]

4x+2y=-6
2y = -4x - 6
y = - 2x - 3
slope = -2
y-intercept when x = 0
so y = -3

answer
slope = -2
y-intercept (0,-3)

10 gallons to 24 gallons identify the percent of change in as an increase or a decrease then find the percent of the of the chai

katovenus [111]

There is 140% increase.

Step-by-step explanation:

Given,

10 gallons to 24 gallons

Old value = 10 gallons

New value = 24 gallons

Change = New value - Old value

Change = 24 - 10 = +14

The positive sign indicates the increase.

Percent increase = $\frac{Change}{Old\ value}*100$

Percent increase = $\frac{14}{10}*100=\frac{1400}{10}$

Percent increase = 140%

There is 140% increase.
