Answer:

48 ft cubed or 576 in cubed

Step-by-step explanation:

The volume of the water is 2304 in cubed. you multiply 12 in by 24 in by 8 in.

the rock makes the water go up 2 in. You then multiply 12 in by 24 in by 10 in. This will equal 2880 in cubed.

2880-2304=

576 in. cubed or 48 ft. cubed

Hurry PLZ!! What is the equation for the line in slope-intercept form? Enter your answer in the box.​
Mandarinka [93]

Step-by-step explanation:

y = ax + b

a is the slope of the line. it is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other.

b is the y-intercept (the y value when x = 0).

once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and solve for b. or we get the point of the line directly on the y-axis.

we see several marked points.

e.g.

(-4, 4) (0, -4)

x changes by +4 (from -4 to 0)

y changes by -8 (from 4 to -4)

the slope (a) is -8/+4 = -2

the y-intercept is given by the point (0, -4), because this is where x=0.

so, it is -4

and the line equation is

y = -2x - 4
