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:
the 8 for 9.25
Step-by-step explanation:
that is the best deal because 1.25 dollars per apple for for the 5 apples for 6.25 dollars rather than 1.15 dollars per apple for the 8 apples for 9.25 dollars so therfore 8 for 9.15 is overall a better for the price per apple
I cannot see what you have showed. It wont pop up. :( Im sorry
Formula
3p < 14
step 1 : 3p / 3 < 14 / 3
; divide 3p, by 3, and 14 by 3
p is about 4.67 ( rounded, original is 4.66666666666666.... etc)
