Answer:
14.75
Step-by-step explanation:
12.50*0.18 = 2.25
12.50 + 2.25 = 14.75
the value of Y is when X crosses the X axis.
Answer:
n= 3 and n = -3
Step-by-step explanation:
In general
|n| = a <=> n = a or n= -a (for n and a are real numbers)
The slope of the given line is 1/3.
The perpendiculars all have the negative reciprocal slope, -3.
<span>A. y + 2 = -3(x-4)
Yes, slope -3.
B. y - 5 = 3(x+11)
No, slope 3.
C. y = -3x - 5/3
Yes, slope -3.
D. y = 1/3 x - 2
No, that's slope 1/3.
E. 3x + y = 7
</span>
That's
y = -3x + 7
Another slope -3, Yes.
Step 1: set equations equal to eachother
2x+2=x-1
which equals to x=-3
so the answer is one.
