Answer: It will take Damon 6 weeks to save the money he needs to buy the snowboard
Step-by-step explanation:
First, let's see what the problem is giving us:
-The variable X will represent the number of weeks it will take Damon to save the money he needs.
- Damon has $40
- Damon is going to safe $20 weekly
- The snowboard costs $160
Therefor:
Our equation will be: $40 + $20X = $160
Step 1
We need to isolate the variable by subtracting in both sides of the equation 40 in order to maintain the equality.
40 - 40 + 20X = 160 - 40
This will let us with 20X = 120
Step 2
We have to isolate the variable again, but this time (because the variable is being multiplied by 20) we have to divide on both sides of the equation.
20X/20 = 120/20
Therefore: X=6

Answer:
3in up per foot across
Step-by-step explanation:
4ft across 12in height
6ft across 18in height
So for every 2ft it goes up 6” which is a ratio of 1ft:3in so the answer to the rate of change is 3in up per 1ft across
For this case we have that by definition, the equation of a line in the slope-intercept form is given by:

Where:
m: Is the slope
b: Is the cut-off point with the y axis
We have the following equation:

We manipulate algebraically:
We subtract 10 from both sides of the equation:

We subtract 3x from both sides of the equation:

We multiply by -1 on both sides of the equation:

We divide between 5 on both sides of the equation:

Thus, the equation in the slope-intercept form is
