Which expressions record the product of exactly two factors ?

Answers

Answer 1

Answer:

Answer:

B 5 *(x+y)

C (x-y) *(x+y)

Step-by-step explanation:

A. x+y There is not product here Remember product is multiply

B 5 *(x+y)

There are two factors and they are multiplied

5 is one factor (x-y) is the other

C (x-y) *(x+y)

There are two factors and they are multiplied

(x-y) is one factor and (x+y) is the other factor and they are multiplied

D x*y*z

There are three factors multiplied here

Answer 2

Answer:

Answer:

B. 5(x + y)

C. (x - y)(x + y)

A used book sale charged $7.50 for hardcovers and $1.25 for paperbacks. During the sale, 15 hardcovers were sold and the sale earned $166.25. Write and solve an equation to determine the number of paperbacks, p, that were sold. 20 points i think

Answers

Answer:

43 paperback books

Step-by-step explanation:

7.50(15) + 1.25x = 166.25

112.50 + 1.25x = 166.25

Subtract 112.50 from both sides

(112.50 - 112.50) + 1.25x = (166.25 - 112.50)

1.25x = 53.75

Divide 1.25 from both sides

x = 43

Given the parent function of f(x) = x3, what change will occur when the function is changed to f(x) − 3?

Answers

For this case we have that the main function is given by:

We apply the following transformation:

Vertical displacements:

Assume k> 0

To graph y = f (x) - k, move the graph k units down.

For k = 3 we have:

Answer:

when the function is changed to f (x) - 3 the change that will occur is:

Vertical displacement 3 units down.

the function line will move down 3 units.

a hockey season ticket holder pays 72.48 for her tickets plus 6.00 for a program each game each game a second person pays 18.08 for a ticket to every game but doesnt buy programs in how many games will they have paid the same amount

Answers

If Iunderstand the question correct, the hockey season ticket holder paid$72.48 for all of the tickets at once, and then $6.00 for each gamethereafter. The second person pays $18.08 for a ticket per game.

So then let g = the number of games. The problem can be written as a system of equations:

Person 1 = 72.48 + 6g
Person 2 = 18.08g

We are looking for when the number of games for both are the same. To dothis, just set them equal to each other and solve for g.

72.48 + 6g = 18.08g
Subtract 6g:
72.48 = 12.08g
Divide by 12.08:
g = 6

So after 6 games, the two would have paid the same price.

What is the value of the expression 6+18÷3×4

Answers

Hi! Ok so you use PEMDAS to figure these out.
So first we can cancel out parenthesis and exponents since there are none in this equation.
Now we do multiply and divide from left to right.
So first 18/3=6
So 6+6*4
Now we do 6*4=24
Now add and subtract
Then 6+24=30
So your answer is 30

it would be 30 cuz of the PEMDS
18 ÷ 3 =6
3 × 4 = 24
24 + 6 =30

Determine the domain and range of the function F(x)=(x-3) {exponent of 2 behind the parentheses}

Answers

That's a parabola. Inside the parenthesis the x-3 affects the placement on the x axis. since is subtracting you move the vertex 3 to the right(because its backwards like that) There is no limit to the x, as it will slowly mom out forever even when its so steep that in reality you dont care, so domain is infinite or all real numbers. the parabola is positive so it moves up forever, but it never goes below its vertex on the x axis.
Domain=all real numbers
Range= all real numbers>or = 0
