Step-by-step explanation:

We are asked to find a slope whilst given a graph.

To solve for slope, we must pick two coordinate points that are not decimals and following the formula of rise over run, which in basic terms y over x.

So based on what I see, I can see (1, 1) and (2, 5).

The rise over run is as followed :

[tex]\frac{y2 - y1}{x2 - x1}[/tex]

2 and 1 meaning the first and second number within the coordinate, so substitute :

[tex]\frac{5 - 1}{2 - 1}[/tex]

[tex]\frac{4}{1}[/tex]

Divide :

[tex]4[/tex]

4 is our slope.

Examine the solution to the equation.
-6(x + 5) + 3 = -2(x + 4) - 4x
-6x - 30+3=-2x–8 – 4x
Which statements accurately describe this equation?
Check all that apply.
This equation has one solution.
This equation has no solution.
This equation has infinitely many solutions.
Any input value for the variable will generate a true
equation.
-6x-27 = -6x - 8
-27 = -8
Any input value for the variable will generate a false
equation.

An African elephant weighed 209 lbs when it was born. Baby elephants gain an average of 38 lbs per week.
How many weeks will it take for the baby elephant to weigh 1197lbs?

Answers

Let the number of weeks be x
38x + 209 = 1197
Subtract 209 on both sides
38x = 1197
Divide 38 on both sides
x = 31.5 weeks

A hoodie is on sale for $48. This sale price is 80% of the original price. What was the original price of the hoodie?

Answers

Answer:  60 dollars

===============================================

Work Shown:

x = original price

y = sale price

The sale price is always smaller than the original price, so y < x.

The equation linking the two variables is

y = 0.8x

since 80% = 80/100 = 0.8

We know the sale price is $48, which means y = 48. This leads to:

y = 0.8x

0.8x = y

0.8x = 48

x = 48/0.8

x = 60

The original price was $60

Note: since the sale price is 80% of the original price, this must mean that we have a 20% discount (100% - 80% = 20%)
