Answer:
[tex]y = 2x + 3[/tex]
Step-by-step explanation:
First, we can find the slope of the line.
[tex]m = \frac{y1-y2}{x1-x2}\\m=\frac{9-5}{3-1}\\m = \frac{4}{2}=2\\[/tex]
Using the [tex]y = mx + b[/tex] equation, we can solve for b
[tex]9 = 2(3)+b\\9 = 6 + b\\b = 9-6 = 3[/tex]
Let's see if [tex]y = 2x + 3[/tex] works
[tex]2(1) + 3 \\2 + 3 = 5\\\\2(3) + 3\\6 + 3 = 9[/tex]
It checks out!
The points (3,2) and (6, r) lie on a line slope -3. Find the missing cordinate
[tex]\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{r}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{r}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{3}}}~~=~~\stackrel{\stackrel{slope}{\downarrow }}{-3}\implies \cfrac{r-2}{3}=-3\implies r-2=-9\implies r=-7[/tex]
2x - 3y = 3
x + 2y = 5
by substitution or elimination
2x - 3y = 3
x + 2y = 5
In the second equation we have an x-term that has a coefficient of 1 (which means the x is all by itself), so we can isolate that x and solve by substitution.
x + 2y = 5
x + 2y - 2y = 5 - 2y
x = 5 - 2y
The expression 5 - 2y will be substituted for x in the first equation.
2x - 3y = 3
2(5 - 2y) - 3y = 3
Solve for y.
2(5 - 2y) - 3y = 3
10 - 4y - 3y = 3 (distribute the 2)
10 - 7y = 3 (collect like terms)
-7y = -7 (subtract 10 from both sides)
y = 1 (divide both sides by -7)
Substitute 1 for y in the second equation to find x.
x + 2y = 5
x + 2(1) = 5
Solve for x.
x + 2(1) = 5
x + 2 = 5 (multiply)
x = 3 (subtract 2 from both sides)
Always check your work. Substitute into the original system.
2x - 3y = 3
2(3) - 3(1) = 3
6 - 3 = 3
3 = 3
x + 2y = 5
3 + 2(1) = 5
3 + 2 = 5
5 = 5
Answer:x = 3 and y = 1; (3,1)

A lawyer has an annual income of $173, 482 and will pay a 5.5% income tax rate. What is the amount of income tax in dollars and cents that the lawyer will have too pay?
Final answer:
The lawyer with an annual income of $173,482 and a tax rate of 5.5% will pay $9,541.51 in income taxes.
Explanation:
To calculate the amount of income tax that the lawyer needs to pay, we multiply their annual income by the income tax rate. In this case, the lawyer has an annual income of $173,482 and the income tax rate is 5.5%. The calculation would be:
Income Tax = Annual Income × Income Tax Rate
Income Tax = $173,482 × 0.055
Income Tax = $9,541.51
Therefore, the lawyer will pay $9,541.51 in income taxes.
There is a spinner with 13 equal areas, numbered 1 through 13. If the spinner is spun one time, what is the probability that the result is a multiple of 6 or a multiple of 4?
Answer:
5 out of 13
Step-by-step explanation:
you will see all the multiples of six and 4 between 1 and 13.Which are
6=6 and 12
4=4,8,12
which are five numbers so 5 out of 13
-9x-6y=15,9x-10y=145
-9x-6y=15
9x-10y=145
Find y first by eliminating the x.
Add the two equations together.
-9x+9x-6y+-10y=15+145
-6y+-10y=15+145
-6y-10y=160
-16y=160
divide both sides by -16 to get +y
-16y/-16=160/-16
y=-10
Use the substitution method to find x
-9x-6y=15
-9x-6(-10)=15
Do the bracket first
-9x+60=15
Move +60 to the other side. Sign changes from +60 to -60.
-9x+60-60=15-60
-9x=-45
Divide both sides by -9
-9x/-9=-45/-9
x=5

You are playing basketball with your friends. The height (in feet) of the ball above the ground t seconds after a shot is released from your hand is modeled by the function f(x)=-16^2 + 32t + 5.2
Answer:the ball is released when t = 0
The ball is 5.2 feet above the ground when it is released
The ball is 5.2 feet in height from the ground and it will hit the ground after 2 seconds.
What is a function?
A certain kind of relationship called a function binds inputs to essentially one output.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
Given the function has height with time t
f(x)=-16t² + 32t + 5.2
At the time of release, the value of time t will be 0
So, t = 0
f(x) = 0 + 0 + 5.2 ⇒ f(x) = 5.2 feet
So height is 5.2 feet
Now,
The time taken to cover this height will be
5.2 = 16t² + 32t + 5.2
16t² + 32t = 0
16t(t + 2) = 0
t = 0 and -2
Since if some height exists then time can never be 0 and time also does not exist in negative so consider 2.
Hence "The ball is 5.2 feet in height from the ground and it will hit the ground after 2 seconds.

how do you solve 2i and 2ii
Answer:
15 and 21
Step-by-step explanation:
Given the n th term formula
T = 2n + 5
To find the 5 th and 8 th terms substitute n = 5 and n = 8 into the formula
[tex]T_{5}[/tex] = (2 × 5) + 5 = 10 + 5 = 15
[tex]T_{8}[/tex] = (2 × 8) + 5 = 16 + 5 = 21
Given:
Tn = 2n+5
`The fifth term, i.e., n=5Substituting the value inside the formula we get,
2(5) + 5 => 10 + 5 => 15
2. The Eighth term, i.e., n=8
Substituting the value inside the formula we get,
2(8) + 5 => 16 + 5 => 21
12x +10+3+8x ? What do I have to do ?
Simplifying
12x + 10 + 3 + 8x = 0
Reorder the terms:
10 + 3 + 12x + 8x = 0
Combine like terms: 10 + 3 = 13
13 + 12x + 8x = 0
Combine like terms: 12x + 8x = 20x
13 + 20x = 0
Solving
13 + 20x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + 20x = 0 + -13
Combine like terms: 13 + -13 = 0
0 + 20x = 0 + -13
20x = 0 + -13
Combine like terms: 0 + -13 = -13
20x = -13
Divide each side by '20'.
x = -0.65
Simplifying
x = -0.65
Answer:
You have to do like terms
Step-by-step explanation:
12x+10+8+8x
12x+8x = 20x
10+3 = 13
your answer would be

PLEEASSSSEEEE HHEEEEELLLLPPPPPPPP !!!!!!!!!!!!!!!!!!!!!!!!!!! Circle R is shown. Line segments Q R and S R are radii. The length of Q R is 18. Sector Q R S is shaded. The measure of central angle QRS is StartFraction 8 pi Over 9 EndFraction radians. What is the area of the shaded sector? 36Pi units squared 72Pi units squared 144Pi units squared 324Pi units squared
Answer:
[tex]144\pi\ un^2.[/tex]
Step-by-step explanation:
In the attached diagram, circle R is shown. Line segments QR and SR are radii and QR = SR = 18 units.
The measure of the central angle QRS is [tex]\dfrac{8\pi}{9}[/tex]
1. Find the area of the whole circle:
[tex]A_{circle}=\pi r^2=\pi \cdot 18^2=324\pi \ un^2.[/tex]
2. Note that the whole circle is determined by the full rotation angle with measure [tex]2\pi[/tex] radians. So,
[tex]\begin{array}{cc}\text{Angle}&\text{Area}\\ \\2\pi &324\pi \\ \\\dfrac{8\pi }{9}&A_{sector}\end{array}[/tex]
So, write a proportion:
[tex]\dfrac{2\pi}{\frac{8\pi}{9}}=\dfrac{324\pi}{A_{sector}}[/tex]
Cross multiply
[tex]2\pi \cdot A_{sector}=324\pi \cdot \dfrac{8\pi }{9}\\ \\A_{sector}=162\pi \cdot \dfrac{8}{9}=144\pi\ un^2.[/tex]

Answer:
4x + 5y = -10 or y = -⅘x - 2
Step-by-step explanation:
First, find the rate of change [slope]:
-y₁ + y₂\-x₁ + x₂ = m
[tex] \frac{ -2 - 6}{5 + 5} = - \frac{8}{10} = - \frac{4}{5} [/tex]
Then use the Point-Slope Formula since we are given points. Now, according to this formula, all negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs. It does not matter which one you choose:
y - y₁ = m(x - x₁)
y + 6 = -⅘(x - 5)
y + 6 = -⅘x + 4
- 6 - 6
_______________
y = -⅘x - 2
If you want it in Standard Form:
y = -⅘x - 2
+⅘x +⅘x
___________
⅘x + y = -2 [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅘x + y = -2]
4x + 5y = -10 >> Line in Standard Form
__________________________________________________________
y - 2 = -⅘(x + 5)
y - 2 = -⅘x - 4

______________
y = -⅘x - 2
y = -⅘x - 2

Allen Barry deposited checks
totaling $1,584.19 into his savings
account. He withdrew $96.00 while
depositing some loose change. Allen's
total deposit was $1,530.24. How much
did he deposit in loose change?
Answer:
$42.05
Step-by-step explanation:
Take $96.00 from 1,584.19 to figure out how much he had before he deposited
1,584.19 - 96 = 1,488.19
Now take away what he had after he took 96, to after he added.
1,530.24 - 1,488.19 = 42.05

Liam bought a comic book and had $5 left. If he had a total of $8 walking into the store, how much did he spend on the comic book?
Liam used the equation 5x=8 to model the problem. He said that x represents the amount of money he spent. Liam said that the solution, x=1.6, means that he spent $1.60. Is he correct? Why or why not? If he is incorrect find the correct answer showing your work.
Pls Help Me
Answer: The comic book was $3.
Step-by-step explanation:
Instead of 5x=8, it should have been 5+x=8 because he only purchased a single comic book. Subtract 5 from 8 and your X value is 3.
Answer:
Liam spent $3 on the book.
Step-by-step explanation:
Liam bought a comic book and had $5 left.
He had a total of $8 walking into the store, so he spent [tex]8-5=3[/tex] dollars on the comic book.
Liam used the equation 5x=8 to model the problem.
This is wrong. The correct form would have been [tex]8-x=5[/tex] or [tex]5+x=8[/tex] where x represents the amount of money he spent.
Hence, Liam spent $3 on the book.
