Zc and Ze

Step-by-step explanation:

The two angles are vertical because they are vertically aligned with line x. If you were to draw a line straight through the middle of them they would have an equal amount of space one each side.

Answer:

c

Step-by-step explanation:

the expression is 24 - (-6) and there is an understood -1 being multiplied by -6.

when you multiply the  -1 by -6 you get 6, so the expression becomes 24+6, so the equivalent expression is c.

hope this helps!

Answer: 24-(-6) = 24+6

Two negatives make a positive.

Answer:

A. (9, –36)

Step-by-step explanation:

The equations are given as:

i) y = -3x - 9

ii) y= 1/3 x - 39

Use equation i) in equation ii)

-3x - 9 = 1/3 x - 39 -------multiply each term by 3 to remove the fraction

-9 x - 27 = x - 117

collect like terms

-9 x- x = -117 + 27

-10 x = -90

10x = 90

x = 90 / 10

x = 9 ------------iii

Use equation iii  in i

y = -3x - 9  

y = -3 * 9 - 9

y= -27 - 9

y= -36

Hence,

x = 9  , y = -36

Answer:

  a.  40

  b.  0

  c.  50

Step-by-step explanation:

a) 46 + (-2k) for k = 3 is ...

  46 + (-2(3)) = 46 -6 = 40

__

b) 46 + (-2k) for k = 23 is ...

  46 + (-2(23)) = 46 -46 = 0

__

c) 46 + (-2k) for k = -2 is ...

  46 + (-2(-2)) = 46 +4 = 50

Answer:

y = 20x

Step-by-step explanation:

y is the total amount that ricky will pay for the CDs.

x is the number of CDs that ricky bought.

so, in this case, if you replace the x by 600 :

y=20 x 600, witch means that the value of y is :

y = 12000 dollars.

Answer:

Meg makes more money per hour.

Step-by-step explanation:

Given that,

Meg worked for 4 hours and earned $31 . Gabby worked for 5 hours and earned $37.50.

We need to find who makes more money per hour.

For Meg,

Money per hour = [tex]\dfrac{31}{4}=\$7.75[/tex]

Fr Gabby,

Money per hour = [tex]\dfrac{37.50}{5}=\$7.5[/tex]

$7.75 is more than $7.5. It means Meg is making more money per hour.

Answer:

They drank the same amount of milk

Step-by-step explanation:

Equivalent Fractions

Given the fractions

[tex]\frac{a}{b}, \ \frac{c}{d}[/tex]

They are equivalent if:

[tex]\frac{a}{b}= \frac{c}{d}[/tex]

Using cross-multiplication:

ad = bc

We are given Gabriela drank 3/4 of her glass of milk and Jenny drank 6/8 of hers. If both glasses were the same size, we can find if they drank the same amount of milk by proving:

[tex]\frac{3}{4}= \frac{6}{8}[/tex]

Using cross-multiplication:

3*8 = 4*6

Since 24 = 24 is true, we can say they drank the same amount of milk

Answer:

2x ^5  sqrt( 6x)

Step-by-step explanation:

sqrt( 3 x^4)  * sqrt( 8 x^7)

Multiply them together

sqrt( 3x^4 * 8x^7)

sqrt( 24 x^ (4+7))

sqrt( 24 x^11)

We can simplify

sqrt(24) sqrt(x^11)

sqrt( 4*6) sqrt( x^10) sqrt(x)

sqrt(4) sqrt(6)   x^5sqrt(x)

2 sqrt(6)  x^5sqrt( x)

Combining the square roots

2x ^5  sqrt( 6x)
