Answer:
See below
Step-by-step explanation:
We first have to understand the parts of a y=mx+b equation
y=mx+b
m: Is the slope
b: Is the y-intercept
x: is the x part of (x,y)
y: is the y part of(x,y)
So...
if we use an example ordered pair like (1,3)
and a slope of 2
We can plug everything into y=mx+b to get
1=2*3+b which simplifies to b= -5
Now, you can use this concept to fill in the blanks below:
Use the two ordered pairs to find the slope, (m).
Then substitute the slope, and (one set of ordered pairs) into y=mx+b to solve for (b).
What we need to do with this problem is multiply the amount the computer costs ($350) by the tax rate (6%). To do this, we first need to convert the percentage to a decimal, so we divide the 6 given by 100, leaving us with .06. Next, we need to multiply the $350 by the .06, giving us $21 as the amount we should be paying for sales tax. So your answer should be 2) $21.00!
How are you making a rectangular frame but it needs to be a triangle?
The coordinates for D are (-4, -7)
First we must locate point B as it is vital to finding the midpoint of BD. To do this, we take the average of the endpoints AC since B is its midpoint.
x values = -9 + 1 = -8
Then divide by 2 for the average -8/2 = -4
y values = -4 + 6 = 2
Then divide by 2 for the average 2/2 = 1
Therefore B must be (-4, 1)
Now we know the values of E must be the average of B and D. So we can write equations for each coordinate since we know they are averages.
x - values = (Bx + Dx)/2 = Ex
(-4 + Dx)/2 = -4 ---> multiply both sides by 2
-4 + Dx = -8 ---> add -4 to both sides
Dx = -4
y - values = (By + Dy)/2 = Ey
(1 + Dy)/2 = -3 ---> multiply both sides by 2
1 + Dy = -6 ---> subtract 1 from both side
Dy = -7
So the coordinates for D must be (-4, -7)
