Answer:
3x-8
Step-by-step explanation:
math
Answer:
y=3x-8
Step-by-step explanation:
The slope of this is the rise over the run. Using the points, we can do (10-4)/(6-4) to get the slope. After solving this, we get 3 as the slope! Slope intercept form is in y=mx+b where m is the slope and b is the y-intercept.
So, y=3x+b
We can insert any of those coordinates into this equation and solve for b to get the y-intercept. If we insert (4,4), then we get 4=3(4)+b
: 4=12+b
:-8=b
Now that we have -8 as the y-intercept, we can insert that as b to get y=3x-8 as the equation in slope intercept form.

a) no solution
b) u=
c) All real numbers are solution
Answer: u = -2
Step-by-step explanation:
-3(u+4)-2u=2(u+1)
-3u-12-2u=2u+2
-5u-12=2u+2

Using the formula find the slope of a line with the points (10,20) and (30,50).
Answer:
m = 2/3
Step-by-step explanation:
Slope is defined as the ratio rise/run.
As we move from (10, 20) to (30, 50), the run is 30 - 10, or 20, and the rise is 50 - 20, or 30. Thus, the slope of the line is m = 30/20, or 2/3.
As a fundraiser, a club is selling posters. The printer charges a $15 set-up fee, plus $0.85 for each poster. The cost y in dollars to print x posters is given by y = 0.85x +15.
(a) What is the cost y in dollars to print 30 posters? To print 100 posters?
(b) Find the number of posters x if the printer billed the club for costs of $185.
(c) Write the information from parts (a) and (b) as three ordered pairs.
(d) Use the data from part (c) to graph the equation.
(a) The cost y to print 30 posters is $___ and to print 100 posters is $___.
Answer:
See below for answer
Step-by-step explanation:
A. y = 0.85x + 15 when x = 30
y = 0.85(30) + 15
y = 40.5
y = 0.85x + 15 when x = 100
y = 0.85(100) +15
y = 100
B. y = 0.85x + 15 when y = 185
185 = 0.85x + 15
185 - 15 = 0.85x
170 = 0.85x
170/0.85 = x
200 = x
C (30, 40.5)
(100, 100)
(200, 185)

Find the perimeter.Simplify your answer.
Answer:
8y - 80
Step-by-step explanation:
Perimeter, put simply, is all of the sides added up together. It will look like this:
(2y - 10) + (2y - 10) + (2y - 10) + (2y - 10)
Now, let's simplify! We can tell that all of the sides are equal to 2y-10, so we can do this:
4(2y -10)
Now we will distribute:
8y - 80
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
- Heather
Answer:
Its jsut combining like terms
Perimeter is basically the out sides all added up in this case everything is equal
so its
2y-10+2y-10+2y-10+2y-10
8y-40
8y-40 is your final answer
What is 1/6 to the power of 3
Answer:
[tex]\frac{1}{216}[/tex]
Step-by-step explanation:
Exponents on fractions work like this:
[tex](\frac{x}{y} )^a=\frac{x^a}{y^a}[/tex]
Apply that to your problem:
[tex](\frac{1}{6} )^3\\\\\frac{1^3}{6^3} \\\\\frac{1}{216}[/tex]
Answer:
1/216
Step-by-step explanation:
1/6 x 1/6 is 1/36
1/36 x 1/6 is 1/216
How much water can the large water hold?
Answer:
700 ml
Step-by-step explanation:
If the 15cm bottle holds 500ml of water, you can create the ratio of 15:500, which simplifies to 3:100.
Since the second bottle is 21cm, you find 21:x.
Because you already have 3:100 as given from the first bottle, if you multiply both sides by 7 you get 21:700.
This means the second bottle holds 700ml.
Answer:
700 mi of water
Step-by-step explanation:
We can divide 21 by 15 to how many times greater they are to each other
21÷15=1.4
Since the 15 cm bottle of water can hold 500 mi we multiply 500 • 1.4 = 700mi

Complete the table using the equation y = 8x + 8 ( helppp plsss)
Answer:
0, 8, 16, 24, 32
Step-by-step explanation:
plug in the values given for x into the 8x+8 equation
Example:
8(-1)+8
8(0)+8
Answer:
(-1, 0), (0, 8), (1, 16), (2, 24), (3, 32)
Step-by-step explanation:
To find answers to problems like these, take the x-value, which in this case is -1, and replace it with the variable,
y = 8*-1 + 8. Then do the rest, y = -8 + 8, y = 0. You already have the x, -1, and now you got y, 0. Then pit in ordered pairs, x first, then y, (-1, 0)

9. Allen and his two brothers decide to purchase a video game system together. They determine
that each person will need to pay $32.30. How much is the cost of the video game system?
I need a variable, equation, and the solution. Pls help!!!
Step-by-step explanation:
that is so simple, it is already difficult to make it formal, because there are only so few things to deal with. you really need help with this ?
you are not familiar with the situation "hey, this costs $10, we are 5 people, if we buy and then use it together, each one has to pay $2" ?
and this is just the other way around : if 5 people paid $2, how much did they pay together ? $10.
let's make it super formal :
price p = Allen contribution a + brother1 contribution b + brother2 contribution c
p = a + b + c
a = b = c = $32.30
p = $32.30 + $32.30 + $32.30 = 3×$32.30 = $96.90

The Chang family is on their way home from a cross-country road trip. Their starting destination is 2,280 miles from their home. The Chang family can expect to decrease the distance from their home by 60 miles per hour.
Part A: Based on the information provided, write the function d(t) that represents the family's distance (in miles), d, from home after t hours of driving.
Part B: If rate at which the Chang family travels home continues at the same rate, determine the value of d(15) and describe what it means in reference to the situation.
Answer: d is 15 hrs
Step-by-step explanation:
Just substitute 15 in for t in 2280-60t and evaluate to get D(15)
D(15) is how many miles left to drive to get home after 15 hours

"The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00. Write a function to represent this scenario.
Which graph represents this wage increase for x < 12?"
-normally I'd just double-check this but. . . you get it.
Red dots are starting co-ordinates and whites are ending co-ordinates .
So the graph must have red dots at the start of line and not mandatory for at the end of line.
x<12It should not be at end
Check option B
x ends at first point .And also the interval is 2
so Option B is correct

Raffle tickets are being sold for a fundraiser. The function a(n) relates the
amount of money raised to the number of tickets sold, n.
It takes as input the number of tickets sold and returns as output the amount
of money raised.
a(n) = 3n - 30
Which equation represents the inverse function n(a), which takes the money
raised as input and returns the number of tickets sold as output?
The money raised depends only on the number of tickets sold, the inverse equation is found by making the tickets sold the subject.
[tex] \underline {n =\frac{a(n) }{3} + 10}[/tex]
How can the inverse function be found?The given parameters are;
a(n) = The amount of money raised
n = The number of tickets sold
a(n) = 3•n - 30
Solution;
The equation that takes the amount of money raised and returns the number of tickets sold is found as follows;
a(n) = 3•n - 30
a(n) + 30 = 3•n
Therefore;
[tex]n = \frac{a(n) + 30}{3} = \frac{a(n) }{3} + 10[/tex]
The number of tickets sold,
[tex] \underline {n =\frac{a(n) }{3} + 10}[/tex]

Half the sum of a number and 1.75 is −5.1. Enter your answer as a simplified mixed number
The unknown number expressed as a mixed fraction is 11 19/20
Let the unknown number be "x"
The sum of the number and 1.75 is expressed as x + 1.75
Half the sum of a number and 1.75 is 1/2(x+1.75)
Equating the result to -5.1 wil give:
1/2(x+1.75) = -5.1
Solve the resulting equation
x + 1.75 = 2(-5.1)
x + 1.75 = -10.2
x = -10.2 - 1.75
x = 11.95
x = 1195/100
x = 11 95/100
Hence the unknown number expressed as a mixed fraction is 11 19/20

Answer:
Diagram number 3 is not a function.
Step-by-step explanation:
It isn't a function because C goes to 2 different numbers.
Explanation:
For choice (3), the input C maps to more than one output (The values 1 and 3 at the same time). A function must have each input map to one and only one output. So this is why relation (3) is not a function.
The other answer choices (1), (2) and (4) have each input point to exactly one output. So these are functions that can be ruled out.
