Answer:
You need to get x by itself
(x = 1)
Step-by-step explanation:
1. Expand.
-12x - 3 - 8x = - 16 - 7x
2. Simplify
-20x - 3 = -16 - 7x
3. Add 20x to both sides.
-3 = -16 -7x + 20x
4. Simplify.
-3 = -16 + 13x
5. Regroup terms.
-3 = 13x - 16
6. Add 16 to both sides.
-3 + 16 = 13x
7. Simplify.
13 = 13x
8. Divide both sides by 13.
1 = x
9. Switch sides
x = 1
Answer:
n = 9

3n - 5 = 22
<u>Step 2: Solve for </u><em><u>n</u></em>
- Add 5 to both sides: 3n = 27
- Divide 3 on both sides: n = 9
Answer:
7-10. domain is all x, range is all y
11. just name all numbers other than 6, 8, and 10 (1, 2, 7, etc.)
12a. (-1,0), (-2,-1), (0,1) (1,2)
12b. Yes, none of the domains are the same and the ordered pairs listed above all follow the rules stated. If it did not follow the rules, the pair(s) would not be Relation B
Step-by-step explanation:
11: In order for relations to be functions, the "x" of the pair needs to be different from the rest. Having the same "x" as another ordered pair would not make it a function.
12a. Follow the rules they state, x ==> y (which I think means x is the number before y) and y > x, honestly not even sure if this is correct
12b. If x ==> was correct in my interpretation, then the ordered pairs I listed should all fit within the boundaries of what relation B would be defined as.
Answer:
x = 22°
3x + 2 = 64°
Step-by-step explanation:
All angles in a triangle must add up to 180°
90 + x + 3x + 2 = 180
Rearrange and collect like terms and place them on either side
4x = 88
x = 22°
3x + 2
3(22) + 2
= 64°
The interval contains all of the values in the range of the function 32 to 58 dollars.
<h3>How to find the ranges of the function?</h3>
The function is as follows:
p(x) = 12 + 2x
where
- x = number of candies sold during the day.
He sells 10 to 23 candies per day.
Therefore,
x = 10 and x = 23
Hence,
p(10) = 12 + 2(10) = 12 + 20 = 32
p(23) = 12 + 2(23) = 12 + 46 = 58
Therefore, the interval contains all of the values in the range of the function 32 to 58 dollars.
