a bunny hop is a bike trick in which the rider brings both tires off the ground without using a ramp. the table shows the height y (in inches) 10.2, 9.8, 9.4 of a bunny hop on a bike that weighs x pounds 19, 21, 23 a) graph the data then describe the pattern b) write a linear function that relates the height of a bunny hop to weight of the bike c) what is the height of a bunny hop on a bike that weighs 21.5 pounds?​

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

i those same problems in math and dont know how to do them

add 8+12 to get a simplified answer of 12r-20
