Rina8888 [55]

Answer:

2.88

Explanation:

If you break down the equation we see that 8 is the number of boxes and 1.44 is the price of each box. So if you wanted to change the equation the formula would be: (1.44)x = cost so if you wanted to figure out how much 2 boxes would be, you just plug in 2 for x and you get (1.44)2 = 2.88

Answer:

$-\frac{3}{4}$

Step-by-step explanation:

Slope

(2, 5) and (14, -4)

_______________

When we solve for slope within two points, we have to follow the formula of slope.

$\frac{y^2-y^1}{x^2-x^1}$

X and Y - The first and second number in both points

1 and 2 - The first or second number within one point

Substitute :

$\frac{-4-5}{14-2}$

$\frac{-9}{12}$

Simplify :

$-\frac{3}{4}$

Solve the system of equations using substitution or elimination:<br> x = 3y + 6<br> 2x - 4y = 8

dem82 [27]

Answer:

x=0, y=-2

Step-by-step explanation:

Let x=3y+6 be equation 1

and 2x-4y=8 be equation 2

sub equation 1 into equation2,

2(3y+6)-4y=8

6y+12-4y=8

2y=-4

y=-2

sub y=-2 into equation 1,

x=3(-2)+6

x=0

sub is an abbreviation for substitute
