Step-by-step explanation:
Any line has an equation ax+by+c=0 with some constants a, b and c. Because your line passes through the points (-1,1) and (3,5), you have two equations, -a+b+c=0 and 3a+5b+c=0. If you find a solution to these equations, you will find an equation of your line.
A 324 -inch pipe is cut into two pieces. One piece is five times the length of the other. Find the length of the shorter piece.
Answer:
64.8 in
Step-by-step explanation:
The pipe is 324 in and you cut in in two. Since we know that one piece is five times the length of the other, we can make the equation 324=5x. Divide both sides by five gets us 64.8 = x.
To check our work, let's multiply 64.8 by 5. It does equal 324 so we are correct.

Three friends at a video arcade win a total of 248 tickets. They decide to share the tickets equally. About how many tickets will each friend receive? Solve this problem using any strategy you choose
Answer:
82.67 tickets
Step-by-step explanation:
Since the tickets are shared equally, the number of tickets each friend would receive is given as: x
The total number of tickets = 248 tickets
Hence:
248 = 3 × x
3x = 248
x = 248/3
x = 82.666666667 tickets
x ≈ 82.67 tickets
Hence, each friend would receive about 82.67 tickets

On a park ma, the ranger station is located (2.5, 3.5) and the nature center is located at (0.5, 4). Each unit in the map is equal to 0.5 mile. What is the approximate distance between the ranger station and the nature center?
Answer: [tex]1.0308\text{ miles}[/tex]
Step-by-step explanation:
Distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] :
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The ranger station is located (2.5, 3.5) and the nature center is located at (0.5, 4) .
Distance between ranger station and nature center
[tex]\sqrt{(2.5-0.5)^2+(3.5-4)^2}=\sqrt{2^2+(-0.5)^2}\\\\=\sqrt{4+0.25}\\\\=\sqrt{4.25}\\\\=2.0616\text{ units}[/tex]
Each unit in the map is equal to 0.5 mile.
Hence, Distance between ranger station and nature center = [tex]2.0616\times0.5=1.0308\text{ miles}[/tex]

Solve linear equations
Solve for x
3х – 10 = 16
Answer:
x=26/3
Step-by-step explanation:
3x-10=16
add 10 to both sides
3x=16+10
simplify
3x=26
divide both sides by 3
x=26/3
What is the reciprocal of 7? Enter your answer in the space below, using a slash mark (/) as a fraction bar when needed.
The reciprocal of 7 is 1/7.
What is a reciprocal?The definition of reciprocal in mathematics is the inverse of a value or a number. If n is a real number, then 1/n will be n's reciprocal.
Given:
The number is 7.
Let n be the reciprocal of 7.
If n is a real number, then 1/n will be n's reciprocal.
To find the reciprocal of 7:
We need the value that can give us 1 when multiplied by 7.
That means,
n x 7 = 1
Divide by 7 to both sides,
n = 1/7
Therefore, the reciprocal is 1/7.

The model below represents an equation. Which value of X makes the equation true?
Answer:
A) x = -1/4
Step-by-step explanation:
There are 4 x's, 4 1's on one side of the equation, and 3 1's on the other side
4x + 4 = 3
Subtract 4 on both sides
4x = -1
Divide each side by 4

Erwin began the month with a bank balance of $0. His bank statement shows one credit (+) and one debit (-). HIs balance at the end of the month was $15. What could be the amounts shown as Erwin's bank statement. Explain how you got your answer.
Answer:
Credit ⇒ 45
Debit ⇒ $30
Step-by-step explanation:
Credit = $45
Debit = $30
When an account balance increases it means that it has been credited and when it decreases, it has been debited.
The beginning balance here is $0 and the closing balance is $15.
There were 2 transactions, one credit and one debit.
For the closing balance to be $15, the Credit amount must have been $15 more than the Debit amount.

Sketch the graph of 2y=f(3x-6) -2
Um i think 2yyyy =f 3x-6
The required graph is attached below, which represents the given function f(x)= 3x - 6y - 2.
The below graph of the function f(x) = 3x - 6y - 2 represents a straight line in a two-dimensional coordinate system.
The equation is in standard form, where x and y are variables and the equation is equal to a constant value (-2 in this case).
To graph this equation, we can rearrange it to the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.
By isolating y in the equation, we get y = (3/6)x - 2/6, which simplifies to y = (1/2)x - 1/3.
The slope of the line is 1/2, meaning for every increase of 1 in the x-coordinate, the y-coordinate increases by 1/2.
The y-intercept is -1/3, which is where the line crosses the y-axis.

Answer:
Prancer spent 240$
Dasher spent 120$
Cupid spent 360$
Step-by-step explanation:
Dasher = D
Prancer = P
Cupid = C
"Dasher spent half as much as Prancer"
D = 1/2P
"Cupid spent 3 times more than Dasher"
C = 3 * D
C = 3 * 1/2P
P + c + d = 720
P + 1/2p + 3*1/2P = 720
3P = 720
3P/3 = 720/3
P = 720/3
P = 240
Prancer spent 240$
Dasher spent 120$ (240/2)
Cupid spent 360$ (120*3)
Answer:
Dasher spent $120, Prancer spent $240, and Cupid spent $360

Answer:
75°
Step-by-step explanation:
We can assume that the angle shown and an angle that measures 15° makes a complementary angle. A complementary angles is when two angles add up to be 90°. We can create an equation and simplify:
15 + x = 90
x = 75
