This is for my exit ticket can someone please help me understand

X = 7

Plz double check my work, in case it wrong. Dont want it to be wrong and then you be wrong

Step-by-step explanation:

If you need the answer 21, and you have to find a way to get what the value of X is, you will have to use subtraction from 21.

21 minus 10 = 11.

11 minus 4 = 7 There fore, the answer should be 7 for X

Double check it by doing (7 + 4) + 10 = 21

                                            11 + 10 = 21

                                               21 = 21

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

hope this !

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.
