Answer:

(-1, 3)

Step-by-step explanation:

Because we're reflecting across a line of X, the Y coordinate doesn't change. The X coordinate, on the other hand, does! it goes from 5 to -1. So we get the transformation (5, 3) -> (-1, 3)

A book with a base price of $15.75 is marked up by 65%. What is the new price, to the nearest cent?
Vaselesa [24]
15,75 - 100 %

100 % =  100/100 = 1

Then every number multiplied by 1 is 100 % of itself.

If the book was marked up 65% of what is was before, it makes a price of 165% when compared to the original.

165% = 165/ 100 = 1,65

15,75 . 1,65 = 25,9875

25,99 is the nearest option.

Amber, Bernie, and Carlos are working on a problem together. Their goal is to correctly apply the difference of cubes formula to
NeX [460]

Answer: Carlos is correct

Step-by-step explanation:

2x^5-250x^2

The first step is to factorize out 2x^2

2x^2(x^3-125)

This can be rewritten as

2x^2(x^3-5^3),

Recall, difference if cube (a^3-b^3)

= (a-b)(a^2 +ab + b^2)

from our equation,

a= x

b = 5.

So the difference of cubes will be

2x^2[(x-5) (x^2 + 5x + 5^2)]

=2x^2[(x-5) (x^2 + 5x + 25)]

Carlos followed these steps. So he is correct. Carlos is correct because he correctly factored the GCF, identified a and b, and applied the difference of cubes method.

Amber is incorrect because 125 is equal to b3, not b.

Bernie is incorrect because x2 is not the GCF of the polynomial. The GCF is 2x^2.

Are two lines parallel, perpendicular or neither 3x+7y=15 and 7x-3y=6
maw [93]

Answer:

The lines are perpendicular

Step-by-step explanation:

we know that

If two lines are parallel, then their slopes are equal

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

we have

3x+7y=15 ----> equation A

isolate the variable y

7y=-3x+15

Divide by 7 both sides

y=-\frac{3}{7}x+\frac{15}{7}

The slope of the line A is m_A=-\frac{3}{7}

7x-3y=6 ----> equation B

isolate the variable y

3y=7x-6

Divide by 3 both sides

y=\frac{7}{3}x-2

The slope of the line B is m_B=\frac{7}{3}

Compare the slope of both lines

m_A=-\frac{3}{7}

m_B=\frac{7}{3}

so

m_A \neq m_B ----> the lines are not parallel

Find the product of the slopes

-\frac{3}{7}(\frac{7}{3})=-1 ----> the lines are perpendicular
