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>
Answer: $14.02
Step-by-step explanation:
Marked down by 45% means it will have a 45% percent discount.
Subtract 45% from 100% then multiply it by the amount .
100% - 45% = 55%
55% * 25.49 = 14.0195 Round it to the nearest hundredth to convert it to money.
14.0195 = 14.02
Answer:
C.77
Step-by-step explanation:
You add all the 5 numbers together and then divide the sum by 5.
Answer:
Step-by-step explanation:
Assuming you are supposed to simplify:
Then we need to apply the product rule of indices.
So we multiply to get:
We now simplify the exponents to get:
Therefore the required product is
