Step-by-step explanation:
Answer:
the first is 432
Step-by-step explanation:
Answer: (- 2h + 1) + 2(3h - 4) = 4h -7
Step-by-step explanation:
First, remove unnecessary parentheses
- 2h + 1 + 2(3h - 4)
then distribute 2 through the parentheses
- 2h + 1 + 2(3h - 4) = -2h + 1 + 6h -8
Combine like terms
-2h + 1 + 6h -8 = 4h + 1 - 8
1-8= 7
So the answer is
4h - 7
You only need two points to describe a linear equation because there are only two unknowns from y=mx+b, namely m, the slope and b the constant or y-intercept.
You can find the slope by finding the change in y divided by the change in x from any two points...here I'll use (0,5) and (1,3)...so the slope or m is:
m=(dy/dx)=(3-5)/(1-0)=-2 now are line so far is:
y=-2x+b and we can use any point now to solve for be, I'll again use (1,3)
3=-2(1)+b
3=-2+b
5=b now we have solved for both m and b our line is:
y=-2x+5
Answer:
<u>C ) 20%</u>
Step-by-step explanation:
A. First you have to find out how much change Cindy would have after paying the total bill
<h3>
$20.00 - $16.50</h3><h2> =<u>
$3.50</u></h2>
B. Then you could use proportions to solve percent problems
<h2>
</h2>
*now plug in the numbers*
1. 
2. 
3. 
4. 
5. 21.21 = X
round to the nearest whole number which would be
<h2>
20%</h2>
