The two lines y=2x+8 and y=2x-12 intersect at x-axis at P nad Q. work out the distance PQ
1 answer:
ANSWER
|PQ|=10
EXPLANATION
The first line is
y=2x+8
We put y=0 to find the x-intercept.
0=2x+8
-2x=8
x=-4
(-4,0) are the coordinates of P.
The second equation is
y=2x-12
To find the x-intercept, we put x=0 into the formula:
0=2x-12
-2x=-12
x=6
The coordinates of Q are (0,6).
The distance between these two points.
|PQ|=|6--4|=10

C) temperature (extremely hot to cool)
Answer:
6/5 is the slope, so x=6/5+2.5y
Step-by-step explanation:
I think
To find the answer, we will have to find the percentage of $273 to $ 3500, and we can use the formula:
In this case:
273/3500 x 100%
=39/500 x 100%
=7.8%
Therefore the annual interest rate would be 7.8%.
