1st month = $8
2nd Month = $16
3rd Month = $24
4th month = $32
5th Month = $40
6th Month = $48
7th Month = $56
8th Month - $64

After 7 months he only has $56 bucks, not enough to hit $60, but after 8 months he finally has at least $60 (in fact, he has $64)

Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2

andrezito [222]

Answer:

$3x+2y=315\\\\2x+4y=450$

is the system of equations representing the situation.

Step-by-step explanation:

Given:

Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes.

Now, to find the system of equations representing the situation.

Let the number of haircuts be $x.$

Let the number of hair dyes be $y.$

So, Alexandra can give 3 haircuts and 2 hair dyes in:

$3x+2y=315.$

Now, giving 2 haircuts and 4 hair dyes in:

$2x+4y=450.$

Therefore,

$3x+2y=315\\\\2x+4y=450$

is the system of equations representing the situation.

Two numbers have a difference of 0.7 and a sum of 1. what are the numbers?

Fofino [41]

In order to determine the value of the numbers, we can set up algebraic equations to solve. For this case, we need to set up two equations since we have two unknown numbers. We do as follows:
let x = first number and y = second number
From the problem statement, we set up equations.
Equation 1 - the numbers have a difference of 0.7
x - y = 0.7
Equation 2 - the numbers have a sum of 1
x + y = 1
Solving for x and y via substitution method,
x - y = 0.7
(1-y) - y = 0.7
1 - 2y = 0.7
-2y = 0.7 - 1 = -0.3
y = 0.15 or 3/20
x - 0.15 = 0.7
x = 0.85 or 17/20
Thus, the two numbers are 0.15 and 0.85.

Write an equation in slope-intercept form of the line that passes through (1,-9) and (-3,-9)

yulyashka [42]

Answer: y = 9

Step-by-step explanation:

Since two points are given , we will use the formula for finding the equation in two points form , which is

$\frac{y -y_{1}}{x -x_{1}}$ = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
