Step-by-step explanation:
1.) Plug in one of the points.
y = 8x + b
6 = 8(4) + b
2.) Solve for b (or [?])
[tex]6 = 32 + b \\ - 32 \: \: \: \: \: \: \: \: \: - 32[/tex]
32 cancels out on the right side.
Subtract 32 from 6, which is -26
3.) -26 = b
4.) Check with other point:
-2 = 8(3) + b
-2 = 24 + b
Cancel out 24 on the right side: 24-24 = 0
-2 - 24 = -26
-26 = b
Use the equation below to find a, if b=11 and c=13.
a=28-b-c
a=?

x-3y-7=0 , 3x-3y-15=0 solve this using cross multiplication
Answer:
x = 4 , y = -1
Step-by-step explanation:
x - 3y = 7 -- (1)
3x - 3y = 15 -- (2)
Rewriting (1), x = 3y + 7 -- (1)'
Substituting (1)' into (2),
3 ( 3y + 7 ) - 3y = 15
9y + 21 - 3y = 15
6y = -6
y = -1 -- (3)
Substituting (3) into (1),
x - 3 ( - 1 ) = 7
x + 3 = 7
x = 4 -- (4)
According to (3) and (4),
x = 4 , y = -1

which two ratios represent quantities that are proportional help i will mark as brainless
Answer:
A
Step-by-step explanation:
So, lets take all of our ratios, and simplfy them the best we can. Once we do this, we can easily compare and see which ratios are and are not similar.
So lets start with A:
21/28 and 12/16
Lets simplfy each fraction.
The greatest number that goes into the numeraotr and denominator(GCF) of 21/27 is 7. Taking out 7 we get:
3/4
We can do the same with the 12/16. 4 goes into both the numerator and denominator:
3/4
So this would work.
Lets look at the others, and see if any others work as well:
56/64 and 36/48
8 goes into both 56 and 64:
7/8
4 goes into 36 and 48:
9/12
These are clearly different.
Next we have 9/10 and 10/9
We can instantly see that one is bigger than 1, and the other is smaller than 1, so they must be different.
Finally we have 5/7 and 7/14
Again, these are clearly different.
If we give both the same denominator, which can be 14, we get:
10/14 and 7/14
We get 10/14 from 5/7 since we need to multiply both numerator and denominator by 2 so that the 7 becomes 14 in the denominator.
10/14 adn 7/14 are clearly different, so these dont work as well.
Only A, which is 21/28 and 12/16, will work.
Hope this helps!

:(
Answer and Step-by-step explanation:
For the first one, x is equal to 61 (180 - 63 - 56 = 61)
and y = 4
51 = 12y + 3
48 = 12y
y = 4
For the second one,
x = 11
11x - 4 = 117
11x = 121
x = 11
y = 5
17y - 8 = 12 + 13y
4y = 20
y = 5

pair if trousers for 75 cedis and sold at 80 cedis. calculate the percentage profit
Answer:
6.7%
Step-by-step explanation:
cost: 75 cedis
sale price: 80 cedis
amount of profit: 80 cedis - 75 cedis = 5 cedis
Now we find what percent 5 cedis is of 75 cedis.
percent = part/whole * 100%
percent = 5/75 * 100%
percent = 0.06666 * 100%
percent = 6.6666%
percent = 6.7%
Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures created by the intersecting lines? Explain.
Answer:
If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

PLZZZZZ HELP ME! The volume of a suitcase is 4,331.25 inches. The length of the suitcase is 22.5 inches inches and the width is 19.25 inches. What is the height? Show your work.
Answer: 10 inches.
Step-by-step explanation:
v=l*w*h
Let’s plug in your numbers:
4,331.25=22.5*19.25*h
Let’s simplify it.
4,331.25=433.125*h
Then divide both sides by 433.125 (.125=1/8 by the way).
10=h

Solve 3x+8=2x+21
Full expansion
Answer:
x = 13
Step-by-step explanation:
3x + 8 = 2x + 21
shift the numbers to make them like terms . Here shift 2x to left hand side when u shift positive becomes negative 2x . and shift positive 8 to right hand side then it become negative 8
3x - 2x = 21 - 8
subtract like terms
x = 13

Jesse has reached 16% of his weekly reading time goal so far this week. If he has read for a total of
32 minutes this week, what is his weekly reading time goal in minutes?
x = time goal
16% = .16
.16 x = 32
x = 32/.16 = ___________ minutes
Jesse' weekly reading time is an illustration of ratio and proportion.
Jesse' weekly reading time is 200 minutes
Represent the reading time with x.
16% of his weekly reading time is given as 32 minutes
This is represented using the following equation
[tex]16 \% \times x = 32[/tex]
Express 16% as decimal
[tex]0.16\times x = 32[/tex]
Divide both sides by 0.16
[tex]x = 32/0.16[/tex]
[tex]x = 200[/tex]
Hence, Jesse' weekly reading time is 200 minutes

There are 4 black cubes, 2 yellow cubes, and 3 orange cubes. Add all of the cubes together to know how many cubes there are total.
4+2+3 = 9
Now that you know there are 9 cubes, you see how many black cubes you can draw out of 9. You can draw 4 black cubes out of the 9 total cubes, so the probability is 4/9.
You see how many yellow cubes you can draw out of 9. You can draw 2 yellow cubes out of the 9 total cubes, so the probability is 2/9.
You see how many orange cubes you can draw out of 9. You can draw 3 orange cubes out of the 9 total cubes, so the probability is 3/9.
