This is no mistake he is the one
It is always possible for the product of a rational number and irrational number to result in a rational value.
Y=mx+b
m=slope
b=y intercept
perpendicuar lines have slopes that multiply to get -1
so
solving for y
add 4x both sides and divide by5 to get
y=4/5x+2
slope is 4/5
perpendicular means the slopes multiply to get -1
so
4/5 times what=-1?
what=-5/4
so
y=(-5/4)x+b
find b
given the point (-15,8)
8=(-5/4)(-15)+b
8=75/4+b
-43/4=b
y=(-5/4)x-43/4
Answer:
c=what is the total cost of ordering one book..
Step-by-step explanation:
Given function:
<u><em>What this means:</em></u>
- 15b+5 means that 15+5..
- b=1 for 15+15
- so if the cost of the book is 15 dollars it adds 5 since you brought that book or for other reasons.
- 15+5=1 book and b represents it.
Therefore, b=the total cost of ordering one book..
