Answer:

A)

x = 7 -2

x = 5

B)

y = 2 -3

y = -1

C)

z = 20 -9

z = 11

D)

p = 3 - 2

p =1

Step-by-step explanation:

You want the variable on one side of the equation to solve.

So we move the numbers on the left side to the right, when you do this you use the opposite operater. Addition and subtraction are opposite operators.

One x-intercept of the graph of the of the cubic function f(x) = x^3 – 2x^2 – 111x – 108 is –9.
katrin2010 [14]

Answer:

The zeros of the given function are -9,-1 and 12.

Step-by-step explanation:

The given function is

f(x)=x^3-2x^2-111x-108

It is given that the x-intercept of the graph is -9, therefore -9 is a zero of the function.

Since -9 is the zero of the function, therefore (x+9) is a factor of f(x). Use synthetics method or long division method to divide the function by (x+9).

f(x)=(x+9)(x^2-11x-12)=0

f(x)=(x+9)(x^2-12x+x-12)=0

f(x)=(x+9)(x(x-12)+(x-12))=0

f(x)=(x+9)(x-12)(x+1)=0

Use zero product property and quote each factor equal to 0.

x=-9,-1,12

Therefore zeros of the given function are -9,-1 and 12.

Which equation represents the line of best fit shown?
Dominik [7]

Answer:

b is the correct answer.

Step-by-step explanation:

Since the slope is negative, it can't be a or d. The y intercept is 810, so c can't be right. Therefore, b is right.

kogti [31]

Answer:

D. The 4th choice.

Step-by-step explanation:

We can see from the graph that the point (-2, -5) is excluded from the line since there is there an open circle.

The domain is all real numbers except -2.

The range is all real numbers except -5.
