Answer:
1/4
Step-by-step explanation:
its kinda hard to
explain
Answer:
y= -1/4x+3/4
Step-by-step explanation:
You are given (-5,2) and x=4
This means that the slope is 4
When finding perpendicular, the slope is the reverse reciprocal of the original slope. The reverse of 4 is -4. The recirprocal is the opposite of -4/1, so it is -1/4.
Slope= -1/4
The slope-intercept form is y=mx+b where you are trying to find b.
Plug in the y value in (-5,2) for y
Plug in the slope for m
Plug in the x value in (-5,2) for x
y=2
m= -1/4
x= -5
y=mx+b
2= -1/4(-5)+b <u>Plug in everything</u>
2= 5/4+b <u>Multiply -1/4 and -5</u>
3/4=b <u>Subtract 5/4 from 2 and you get b</u>
<u />
Since we have b now we can make an equation using it.
y=mx+b <u>Use the form</u>
y= -1/4x+3/4 <u>Plug in m and b</u>
A.
let the number be n.
2n+5=45
2n=40
n=20
Answer:
7/2
Step-by-step explanation:
3 wholes is equal to 6 halves plus a half equals 7 halves
Well, the formula for simple interest is

"I" is interest, "p" is the principal, "r" is the rate, and "t" is the time.
If you substitute the numbers, you get

When you multiply them together, you get

So, the simple interest for 3.5 years is $210.
But, in order to get the total balance, you have to add the interest and the principal together.

So, the balance after 3.5 years is $1,210.
