Use the factor theorem to determine which of the following is a factor of f(x)=x^3+5x2-15x+9

x+2

Step-by-step explanation:

x+2

If x = –2 is a zero, then x + 2 = 0, so x + 2 is a factor. Similarly, if x = 1/3 is a zero, then x – 1/3 = 0, so x – 1/3 is a factor. By giving me two of the zeroes, they have also given me two factors: x + 2 and x – 1/3.

At a farmers' market. Karen and Alice each bought some bread that cost $2 per loaf. Then Karen spent $3 to purchase other items,
Lena [83]

Answer:

(1)

Karen: y = 2x +3

Alice: y = 2x +1

(2): Slope is 2

(3) y intercept

b = 3 --- For Karen

b = 1 --- For Alice

(4) They do not intersect

(5) No solution

(6) No

Step-by-step explanation:

Given

x = loaves

y = amount

Solving (1): Complete the equation.

For Karen:

m = 2 --- the rate

b = 3 --- additional spendings

For Alice:

m = 2 --- the rate

b = 1 --- additional spendings

The general equation is;

y = mx +b

For Karen, it becomes

y = 2x +3

For Alice, it is:

y = 2x +1

(2): The slopes.

In (1), we have:

m = 2 --- the rate (for both Karen and Alice).

This rate implies the slope.

<em>Hence, the slope is 2</em>

(3): The y intercept.

The additional spendings in (1) means the y intercept.

So, we have:

b = 3 --- For Karen

b = 1 --- For Alice

(4) Because they have the same slope, they do not intersect

(5) Number of solutions.

y = 2x +3

y = 2x +1

Subtract both equations

y-y = 2x-2x +3-1

0 = 2

This means there is no solution

(6) Can they spend the same amount on the same number of loaves

In (5), the equations have no solution

<em>Hence, it is not possible to spend the same amount for the same number of loaves</em>

Hey guys please help me

Answer is 20. -4 x 1 is -4 so it doesn’t change. -4 -8 makes it -4 + 8 as there’s two negatives. 9 divided by 3 is 3. So it’s -4 +8 x 3. 8x3 is 24. So -4 + 24 = 20. Therefore final answer is 20
