Answer:
The slope is 1/2 and the y intercept is 7/4
Step-by-step explanation:
2x-4y+7=0
To find the slope, we need to put the equation in slope intercept form
y = mx+b
So we need to solve for y
Subtract 2x from each side
2x-2x-4y+7=0-2x
-4y +7 = -2x
Subtract -7
-4y+7-7 = -2x-7
-4y = -2x-7
Divide by -4
-4y/-4 = -2x/-4 -7/-4
y = 1/2 x +7/4
The slope is 1/2 and the y intercept is 7/4
Answer:
425 miles per hour
Step-by-step explanation:
Find the speed per hour by dividing the distance by the number of hours:
6375/15
= 425
This means the plane traveled 425 miles in one hour.
So, the plane's average speed was 425 miles per hour
Answer:$ 66.5
Step-by-step explanation:
Using ordinary Annuity formula
![FV=\frac{P\times \left [ \left ( 1+r\right )^n-1\right ]}{r}](https://tex.z-dn.net/?f=FV%3D%5Cfrac%7BP%5Ctimes%20%5Cleft%20%5B%20%5Cleft%20%28%201%2Br%5Cright%20%29%5En-1%5Cright%20%5D%7D%7Br%7D)
FV=future value=$24000
P=monthly payment
r=rate of interest =5.4%
for monthly 
n=number of payments 
![24000=\frac{P\times \left [ \left ( 1+0.0045\right )^{108}-1\right ]}{0.0045}](https://tex.z-dn.net/?f=24000%3D%5Cfrac%7BP%5Ctimes%20%5Cleft%20%5B%20%5Cleft%20%28%201%2B0.0045%5Cright%20%29%5E%7B108%7D-1%5Cright%20%5D%7D%7B0.0045%7D)
P=$ 66.501
sop monthly deposit of $ 66.5 is required.
Answer:
x = 218.7
Step-by-step explanation:
To solve for x, we multiply .30 by 729. Once multiplied, we get the answer 218.7. Therefore, x = .30(729) is the same as x = 218.7.
