11. y=-1/3x-4
Plug the slope into m in y=mx+b and then plug in your point and solve for b. You get C
12. Parallel means it has the same slope or the same m, so the -1/2 stays the same and you plug that and your point into the y=mx+b and solve for b again. You get D, y=-1/2x-9
13. Perpendicular means that the slope is the opposite reciprocal so you flip it and multiply it by -1. You then plug that in for your slope and plug in your points and you get A, y=9x+13
Answer:
-1
Step-by-step explanation:
you mutiply the 3 on both sides and then you subtract the 2 from both sides.
-t=1
then u divide by negative 1 which will make the right side number negative
Answer:
a. is 1 and b is 2 and c is 3 I did it in algebra pay attention in class

Answer: A) 1/10</h3>
=============================================
Work Shown:
(4/5) divided by 8
(4/5) divided by (8/1)
(4/5) * (1/8) .... flip the second fraction and multiply
(4*1)/(5*8)
(4*1)/(5*4*2)
1/(5*2) ... the '4's cancel
1/10
--------------
Alternative method:
4/5 = 0.8 when using a calculator or long division
(4/5) divided by 8 = 0.8/8 = 0.1
0.1 = 1/10
The digit 1 in 0.1 is in the tenths place, so that's why 0.1 = 1/10
Or you could use your calculator to see that 1/10 = 0.1
Another idea is to do
0.1 = 0.1/1 = 0.1/1.0 = 1.0/10.0 = 1/10
here I moved the decimal point 2 spots to the right for the numerator and denominator.
