The first one is the answer because he starts with $300 (which would be the b in this case) and he gets $5 for EACH customer (so that would be 5x)

5x + 300 is most appropriate for this question.

Explanation: he gets $5 per bought subscription so the x represents the number of bought subscriptions. he gets an initial pay of $300 so that would be the amount of money he starts with. that’s why the y intercept is 300.

Hope this helps! :)

Answer:

7. 5 $\frac{5}{8}$ pizza

8. B

9. 11 $\frac{1}{5}$ inches

10. -12

11. $\frac{3}{20}$

12. 4

Step-by-step explanation:

7. 3 $\frac{1}{2} \\$ + 2 $\frac{1}{8}$

make them mixed fractions: $\frac{7}{2}$ + $\frac{17}{8}$

get a common denominator by multiplying $\frac{7}{2}$ by 4: $\frac{28}{8}$ + $\frac{17}{8}$

add the numerators: $\frac{45}{8}$

simplify the fraction by dividing 45 by 8: 5 $\frac{5}{8}$

8. 3 x 6 = 18

5 x 6 = 30

7 x 6 = 42

9 x 6 = 54

therefore, y = 6x

9. 5:7 is similar to 8:L

divide 8 by 5: 1 $\frac{3}{5}$

multiply 7 by 1 $\frac{3}{5}$ : 11 $\frac{1}{5}$

L = 11 $\frac{1}{5}$ inches

10. 5 - 2x = 29

subtract 5 from each side: -2x = 24

divide each side by -2: x = -12

11. fruit = 15%

15% = 15/100

simplify by dividing by 5: $\frac{3}{20}$

12. the y-intercept is where the line crosses the y-axis (the vertical one). the line crosses the y-axis at 4.

A triangle with vertices at A(0, 0), B(0, 4), and C(6, 0) is dilated to yield a triangle with vertices at A′(0, 0), B′(0, 10), a

sineoko [7]

ANSWER

The scale factor is
$2.5$

EXPLANATION

The given triangle has vertices,

$A(0,0),B(0,4),\:and\:C(6, 0)$ .

The vertices of the image triangle is,

$A'(0,0),B'(0,10),\:and\:C'(15, 0)$ .

The scale factor is given by

$k = \frac{image \: length}{object \: length}$

So we can use any of the corresponding sides to determine the scale factor,

$k = \frac{|A'B'|}{ |AB|}$

$k = \frac{ |10 - 0| }{ |4 - 0|}$

$k = \frac{ |10| }{ |4 |} = \frac{10}{4} = 2.5$

Or

$k = \frac{|A'C'|}{ |AC|}$

$k = \frac{ |15 - 0| }{ |6 - 0|}$

$k = \frac{ |15| }{ |6|} = \frac{15}{6} = 2.5$

Or

$k=\frac{|B'C'|}{|BC|}$

$k = \frac{\sqrt{(15 - 0)^2+(0-10)^2 }}{\sqrt{(6 - 0)^2+(0-4)^2}}$

$k = \frac{ 5\sqrt{13}}{2\sqrt{13}} = \frac{5}{2} = 2.5$

The correct answer is C
