Zero of 7 with a multiplicity of 3 means one factor is (x-7)^3

Zero of -1 with a multiplicity of 2 means one factor is (x+1)^2

Zero of 5 with a multiplicity of 1 means one factor is (x-5)

Multiplying, we get

f(x) = (x-7)^3(x+1)^2(x-5)

That's already in factored form so we leave it here.

ERROR ANALYSIS Describe and correct the error in finding the x-intercept.
EastWind [94]

The x-intercept is -6

Step-by-step explanation:

In order to find the x-intercept, we put y = 0 and to find the y-intercept we put x = 0

In the given method, x is put equal to zero instead of y as x-intercept had to be found.

Given equation is:

-2x+3y=12

-2x + 3(0) = 12\\-2x +0 = 12\\-2x = 12

Dividing both sides by -2

\frac{-2x}{-2} = \frac{12}{-2}\\x = -6

The x-intercept is -6

A radio station had 205 tickets to a concert. They gave away 4 times as many tickets to listeners as to employees. How many tick
Citrus2011 [14]

Answer:

As per the statement: A radio station had 205 tickets to a concert. They gave away 4 times as many tickets to listeners as to employees.

⇒Let number of tickets Employees have x and Number of ticket Listeners  have 4x

It is also, given that a radio station had 205 ticket to a concert.

⇒ \text{Number of ticket Employees have} +\text{Number of ticket Listeners have} = 205

Then, substitute the given values we have;

4x + x = 205

Combine like terms, we have;

5x = 205

Divide both sides by 5 we have;

x = 41

Therefore, number of tickets did they give away to employees have 41 tickets

Mei bought a box of markers for b dollars, a shoulder bag that cost twice as much as the box of markers and a pen that cost $6 l
Masteriza [31]
Box of markers = $ B

Shoulder bag =  Twice as much as the box of markers = $ 2B

Pen = Six less than the shoulder bag = $ (2B - 6)

Hence, the cost of pen is $ (2B - 6).

in a box full of oranges, apples, and pears in a ratio 2:5:6. What is the total weight of the fruits in the box if it was known
spin [16.1K]

Answer:

31.2 lbs

Step-by-step explanation:

Let 2x = weight of oranges

5x = weight of apples

6x = weight of pears

2x + 5x + 6x = total weight

2x = 4.8

x = 2.4

4.8 + 5(2.4) + 6(2.4) = 4.8 + 12 + 14.4

= 31.2 lbs
