adult ticket = 10

child ticket = 4

Step-by-step explanation:

for example…

  • adult ticket = x
  • child ticket = y

so that we get a system of equations

9x + 5y = 110…Equation 1

x + y = 14…Equation 2

solve the system of equations, this time I will use the Elimination and Substitution method

9x + 5y = 110

x + y = 14 (multiplied by 5)

↓↓↓↓↓↓↓

9x + 5y = 110

5x + 5y = 70

___________ _

4x = 40

<u>x = 10</u>

to find value of y subtitute x to one of Equation. for example from second Equation…

x + y = 14

10 + y = 14

y = 14 - 10

<u>y = 4</u>

∴ So, the number of each ticket was she bought is <u>10 adult ticket</u> and <u>4 child </u><u>ticket.</u>

What is the slope of the line threw (-7,-2) and (-6,7)
miv72 [106K]

Answer:

9

Step-by-step explanation:

To find the slope of a line, calculate the distance between points with a ratio of vertical to horizontal distance. This is done using the formula:

m=\frac{y_2-y_1}{x_2-x_1}

Here the points are (-7,-2) and (-6,7). Substitute and simplify.

m=\frac{7--2}{-6--7}=\frac{7+2}{-6+7}=\frac{9}{1}=9
