Answer:
b=4
Step-by-step explanation:
4b+5=1+5b (subtract 4b on both sides to get the b's together)
-4b -4b
5=1+5b-4b (subtract 1 from both sides)
-1 -1
4=1b (divide by 1)
b=4

Set a proportion 13.50/15 and x/100
13.50x100=1350 1350/15=90 subtract 90 from 100 so 10
10% is the discount rate because 10% of 15 is 1.50 or $1.50
Answer:
3
Step-by-step explanation:
To find the slope of a line going through two points, (x₁, y₁) and (x₂, y₂), we can use the following formula: . Note that it doesn't really matter which points we call (x₁, y₁) or (x₂, y₂).
Let's call (x₂, y₂) = (0, 5) and (x₁, y₁) = (-2, -1). Now, we can plug in the values for x, y₁, x₂, and y₂ into the formula.
We have:
Therefore, the slope of the line is 3. Hope this helps!
