Answer:
"Multiply the previous value by 2"
Step-by-step explanation:
Let's check the first 2 terms for all the answer choices.
1. Add
to the previous value:

Doesn't match.
2. Subtract
from the previous value:

Doesn't match.
3. Divide the previous value by 2:

Doesn't match.
4. Multiply the previous value by 2:

DOES WORK!
Also, doing the same thing with all the other values would give us matching answer. So this choice is right.
Answer:
7
Step-by-step explanation:
We want to evaluate the fraction below for x = 3. We will put the value of x to be 3:

The answer is 7.
Answer: 4. (-1,-1) 3. (3,-2)
4)
Set the equations equal to each other.
4x+3=-x-2
Subtract 3 from both sides
4x=-x-5
Add x to both sides
5x=-5
Divide both sides by 5
x=-1
Next, replace x with -1 in either equation to find y.
-(-1)-2=y
-1=y
3)
Do the same thing for this one and set them equal to each other
-2x+4=-1/3x-1
Add 1 to both sides
-2x+5=-1/3x
Add 2x to both sides
5=5/3x
Divide both sides by 5/3
x=3
Next, replace x with 3 in either equation
-2(3)+4=y
-2=y
Answer:
(a) Neither
(a) Perpemdicular
Step-by-step explanation:
Required
Determine the relationship between given lines
(a)

and

An equation written in form:
has the slope:

So, in both equations:


For both lines to be parallel

This is false in this case, because:

For both lines to be perpendicular

This is false in this case, because:

(b)

and

Write equations in form:


Divide by 5



Divide by 2

In both equations:


For both lines to be parallel

This is false in this case, because:

For both lines to be perpendicular

This is true in this case, because:

Cancel out 2 and 5
