gregori [183]

Answer:

Step-by-step explanation:

Natalie

100 + 10x

Her sister

25 + 25x

Where

x = number of months

Equate Natalie and her sisters equation

100 + 10x < 25 + 25x

100 - 25 < 25x - 10x

75 < 15x

Divide both sides by 15

x < 75 / 15

x < 5

The output of a function is 7 more than 3 times the input find the input when the output is -8

nataly862011 [7]

Answer:

The input is -5 when the output is -8

Step-by-step explanation:

Let

y-----> the output

x ----> the input

we know that

The linear equation that represent this problem is

$y=3x+7$

For y=-8

substitute in the equation and solve for x

$-8=3x+7$

Subtract 7 both sides

$-8-7=3x\\-15=3x$

Divide by 3 both sides

$x=-5$

therefore

The input is -5 when the output is -8
