To solve this you set up the equation: x(8) +12 =y. In this equation x=, the number of paintbrushes and y=, the total cost of the purchase. If you plug in the number of paintbrushes that are being bought you should be able to get your Y(total cost).

A line contains the points (80, -94) and (89, -84).
What is the slope of the line in simplified form?
Answer:
The answer is
[tex] \huge \frac{10}{9} [/tex]
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(80, -94) and (89, -84)
We have
[tex]m = \frac{ - 84 - - 94}{89 - 80} = \frac{ - 84 + 94}{9} = \frac{10}{9} \\ [/tex]
We have the final answer as
[tex] \frac{10}{9} \\ [/tex]

In this case
Rise=2

Answer: m = 2
Step-by-step explanation:
1) m= (y2-y1)/(x2-x1)
2) let say :
y1=0
y2=4
x1=-2
x2=0
3) m= (4-0)/(0-(-2))

rewrite the equation by completing the square 6x + 55 = x^2
Answer:
x=11
x=−5
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 6*x+55-(x^2)=0
-x2+6x+55 =0
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = -1
B = 6
C = 55
Accordingly, B2 - 4AC =
36 - (-220) =
256
Applying the quadratic formula :
-6 ± √ 256
x = ——————
-2
Can √ 256 be simplified ?
Yes! The prime factorization of 256 is
2•2•2•2•2•2•2•2
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 256 = √ 2•2•2•2•2•2•2•2 =2•2•2•2•√ 1 =
± 16 • √ 1 =
± 16
So now we are looking at:
x = ( -6 ± 16) / -2
Two real solutions:
x =(-6+√256)/-2=3-8= -5.000
or:
x =(-6-√256)/-2=3+8= 11.000
Answer:
(x-3)^2 =64

Norachai won 55 lollipops playing the
bean bag toss at the county fair. At school
he gave two to every student in his math
class. He only has 7 remaining. How
many students are in his class?
Answer: 24
Step 1: Subtract 7 because Norachai has seven more lollipops.
55 - 7 = 48.
Step 2: Divide 48 by 2 because he gave every student two lollipops.
48 divided by 2 = 24.
Answer = 24
A teenager puts $50 into an investment account in January. If by December the balance in the account increases by 17%, what is the amount of money in the account in December?.
Answer:
58.50
Step-by-step explanation:
Multiply 50 and .17 which equals 8.5 then add that to 50.
The amount of money in the account in December with a rate of 17% of the initial amount of $50 is $58.5.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
A teenager puts $50 into an investment account in January.
Let, he deposited on first January.
If by December the balance in the account increases by 17%,
Let the amount by the 31 first of December will be
Then the amount will be given as
[tex]A = P (1 + \dfrac{r}{100})^t[/tex]
P = $50
r = 17%
t = 1
Then we have
[tex]\rm A = 50(1 + \dfrac{17}{100})^1\\\\A = 50(1 + 0.17)\\\\A = 50 * 1.17 \\\\A = 58.5[/tex]

David can paint a fence in ten hours. Alex can paint the same fence in eight hours. If
they worked together how long would it take them?
1/10
1/8
9/40
40/9
Answer:
40/9
Step-by-step explanation:
Use the work formula, [tex]\frac{1}{A}[/tex] + [tex]\frac{1}{B}[/tex] = [tex]\frac{1}{T}[/tex], where A is the amount of time it takes one person, B is the amount of time it takes another person, and T is the time it takes for them to work together.
Plug in the times for David and Alex alone:
[tex]\frac{1}{10}[/tex] + [tex]\frac{1}{8}[/tex] = [tex]\frac{1}{T}[/tex]
Find the least common denominator, which is 40.
[tex]\frac{4}{40}[/tex] + [tex]\frac{5}{40}[/tex] = [tex]\frac{1}{T}[/tex]
[tex]\frac{9}{40}[/tex] = [tex]\frac{1}{T}[/tex]
Cross multiply and solve for T:
9T = 40
T = 40/9
So, if they worked together, it would take them 40/9 hours
Answer:
40/9

Solve for x. Round to the nearest tenth of a degree, if necessary.
Answer: x = 52.1 degrees
Step-by-step explanation:
The tangent of an angle is the opposite side divided by the adjacent side.
Therefore, tan(x) = 45/35.
We can find thte value of x by doing the arc tangent of 45/35, which makes x about 52.1 degrees.
