Given:

A graph that contains image and preimage.

To find:

Which figure is the preimage and which figure is the image.

Solution:

Initial figure is known as preimage and translated figure is known as image.

It is given that a triangle was translated 4 units down. It means, the upper triangle is preimage and the lower triangle is the image.

So, ΔFGH is the pre-image and ΔABC is the image.

Therefore, the correct option is B.

108 = -2(-5 - 7b) What does b equal?
mario62 [17]

Answer:

b = 7

Step-by-step explanation:

108 = -2(-5 - 7b)

Distribute -2 to the terms inside the parenthesis:

108 = 10 + 14b

Subtract 10 from both sides of the equation to isolate 14b:

108 - 10 = 10 + 14b - 10

98 = 14b

Divide 14 on both sides of the equation to solve for b:

\frac{98}{14}  = \frac{14b}{14}

7 = b

Mikhael bought refreshments. Sandwiches were $3 each and bottles of water were $0.75 each. He spent $318.75 on a total of 200 it
olga nikolaevna [1]
Sandwiches = S
Water = W

S + W = 200
S +W -W = 200-W
S = 200-W

$3S + $0.75W = $318.75
$3(200-W) + $0.75W = $318.75
$600 - $3W + $0.75W = $318.75
$600 -$2.25W =  $318.75
$600 - $600 - $2.25W = $318.75 - $600
- $2.25W = -$281.25
-$2.25W/-$2.25 =  -$281.25/-$2.25
W = 125

S = 200-125
S = 75

Mikhael bought 75 sandwiches and 125 bottles of water

CHECK
$3S + $0.75W = $318.75
$3(75) + $0.75(125) = $318.75
$225 + $93.75 = $318.75
$318.75 = $318.75

line n passes through the points (-3, -7.5) and (2, -5). tahlia determined that the equation of line n is y = 0.5x. explain the
sweet-ann [11.9K]
<h2>Therefore Tahlia made mistake. Tahlia did not write -6 in her equation.</h2>

Step-by-step explanation:

Given , line n passes through the points (-3,-7.5) and (2,-5)

x_1 = -3 , y_1=-7.5   and     x_2 = 2 , y_2=-5

Therefore the slope of the line is (m)  =\frac{y_1-y_2}{x_2-x_1}

                                                        =\frac{-7.5+5}{2+3}

                                                        =\frac{2.5}{5}   =\frac{1}{2}

Therefore the equation of line is

y-y_1=m(x-x_1)

\Leftrightarrow y+7.5 =\frac{1}{2}(x+3)

\Leftrightarrow y+7.5 = 0.5x+1.5

\Leftrightarrow y = 0.5x+1.5 -7.5

\Leftrightarrow y = 0.5x -6

Therefore Tahlia made mistake. Tahlia did not write -6 in her equation.
