Step-by-step explanation:
1. length = 6 width = 2x + 5
2. length = 3 width = 4x + 10
3. length = 12 width = x + 2.5
Answer:
B. -2
Step-by-step explanation:
Simply plug 3 into the equation and follow the order of operations.
2(3 - 4) + (3(3)) - (3^2)
2(-1) + (9) - (9)
= -2
Answer:
y= -3.5x +10
Step-by-step explanation:
The first thing to do in this equation is solve for m, the slope of the line.
Because we are given that the y-intercept is 10, we know that the graph intercepts at the point (0,10).
We are also given the point (5,-7.5).
Using the two points we can solve for the slope!
To solve for the slope use this formula:
(-7.5 -10) / (5 -0)
= -3.5
So our slope, m = -3.5
The other missing value is b, but is very easy to find.
In this example, b is equal to the y-intercept, so b=10.
Now we can plug in the values we found into the original equation
y =mx+b
y= -3.5x +10
