how do you find the slope and the y-intercept of y=6x-12
Answer:
Slope = 6, y-intercept = -12.
Step-by-step explanation:
Slope is the coefficient of the x-term, which is 6 in this case.
The y intercept is the constant term that comes after the x-term, which is -12.

Tyra buys 14 gallons of gas for $35. How could she figure out how much 1 gallon of gas cost
Answer:
The cost of 1 gallon is $2.5
Step-by-step explanation:
Given
Cost of 14 gallons = $35
Required
Determine the cost of 1 gallon
From the given parameters, we have:
[tex]14\ gallons = \$35[/tex]
Divide both sides by 14
[tex]\frac{14\ gallons}{14} = \frac{\$35}{14}[/tex]
[tex]1\ gallon = \frac{\$35}{14}[/tex]
[tex]1\ gallon = \$2.5[/tex]
Hence,
The cost of 1 gallon is $2.5
Given f(x) = 4x - 3 and g(x) = 7x +5, find f(x) + g(x).
Answer:
Given f(x) = 2x + 3 and g(x) = –x2 + 5, find (g o f )(x).
(g o f )(x) = g( f(x))
= g(2x + 3)
= –( )2 + 5 ... setting up to insert the input
= –(2x + 3)2 + 5

If the triangles are similar, that means their side to side ratios will be the same.
For example, we are given the side lengths 6 and 9 to corresponding sides.
Meaning that the side to side ratios are 6:9, or 2:3.
Using this, we can find the missing side length value.
58:x = 2:3
[tex]\frac{58}{x}=\frac{2}{3}[/tex]
[tex]2x=174[/tex]
[tex]x=87[/tex]
The missing side length is 87.

(4,2) and (7,6)
Answer:
The answer is
[tex]( \frac{11}{2} \: , \: 4)[/tex]Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are

If x = 1, then 3*1 = 3 which when modded with 5, we get 3 as a remainder. In other words, 3/5 = 0 remainder 3. We don't use the quotient at all when it comes to modular arithmetic. All we care about is the remainder.
If x = 2, then 3*2 = 6 which leads to remainder 1 when we divide by 5. Therefore, 3x = 1 (mod 5) when x = 2.
If x = 3, then 3*3 = 9 = 4 (mod 5) because 9/5 = 1 remainder 4.
So 3x = 4 (mod 5) when x = 3.
The final answer is C) 3We don't need to check D since x = 3 is a solution and it's smaller than x = 4.
If you wanted to check x = 4, then 3*4 = 12 = 2 (mod 5) because 12/5 yields a remainder of 2.

f(x)=2x-5 find the inverse
Answer:
1/2x+5/2
Step-by-step explanation:
1. Change f(x) to y
y = 2x – 5
2. Switch x and y.
x = 2y – 5
3. Solve for y by adding 5 to each side and then dividing each
side by 2.
x+5=2y
4. Change y back to f^-1(x)... in other words the inverse
f^-1(x)=(x+5)/2
= 1/2x+5/2
Step-by-step explanation:
y=f-1(x)=1/2(x+5)
explanation: write y equals 2x - 5 and now interchange X and Y it becomes x equals 2y - 5
now solve for y equals F -1 (x) equals 1/2(x + 5)
g(x)= (x + 5) / (2)
is the inverse function of F (x)= 2x - 5

Step-by-step explanation:
To solve this, first, take 22 minutes and divide it by 60 minutes, which is the number of minutes in an hour. Then, add two to the value, and multiply it by six square meters per hour, which is the rate that David can paint the wall. From there, you get 14.2 square meters which he painted in 2 hours and 22 minutes. Divide 14.2 square meters by the length of 11 meters to get 1.290 meters. Since they asked you to round to the nearest meter, you get 1 meter.

hugo received $100 for his bithday. He then saved $20 per week until he had a total of $460 to buy a printer. Use the equation to show how many weeks it took him to save the money.
Answer:
18 weeks
Step-by-step explanation:
So, Hugo received $100 for his birthday.
He saved $20 per week. Let x denote the weeks that passed. Therefore:
[tex]y=100+20x[/tex]
This equation represents the total money y Hugo has after x weeks.
The printer cost $460. Thus, set y to $460:
[tex]460=100+20x[/tex]
Solve for x.
Subtract 100 from both sides:
[tex]360=20x[/tex]
Divide both sides by 20:
[tex]x=18[/tex]
Therefore, it took Hugo 18 weeks to save up $460.
Use the drop-downs to identify the domain and range of the following relation.
{(4, -7), (0, 6), (5,-3), (5, 2)}
What is the domain of this relation?
What is the range of this relation?
Answer:
Domain ( -4,0, 5) Range ( -7, -3, 2, 6)
Step-by-step explanation:
The domain and range of the given relation {(4, -7), (0, 6), (5,-3), (5, 2)}
is:
Domain = { 4, 0, 5, 5 }
Range = { -7, 6, -3, 2 }
Given,
{(4, -7), (0, 6), (5,-3), (5, 2)}
We need to find what is the domain and range of this relation.
What are the domain and range of a function?A function has an input and an output.
Example: f(x) = x + 4
Now,
x = 1, 2, 3
f(1) = 1 + 4 = 5
f(2) = 2 + 4 = 6
f(3) = 3 + 4 = 7
Here,
Domain = 1, 2, 3
Range = f(1), f(2), f(3) = 5, 6, 7
We can also write it as { (1,5), (2,6), (3,7)}
Find the relation.
(4, -7)
Here,
domain = 4 and range = -7
(0, 6)
domain = 0 and range = 6
(5,-3)
domain = 5 and range = -3
(5, 2)
domain = 5 and range = 2
Find the domain and range of {(4, -7), (0, 6), (5,-3), (5, 2)}.
Domain = { 4, 0, 5, 5 }
Range = { -7, 6, -3, 2 }
Thus the domain and range of the given relation {(4, -7), (0, 6), (5,-3), (5, 2)}
is:
Domain = { 4, 0, 5, 5 }
Range = { -7, 6, -3, 2 }

Answer:
He can buy up to 20 tickets (ie 20 tickets or less)
The equation is 10+3.25x+5 = 80
========================================================
Explanation:
10 = admission cost
3.25 = cost per ticket
x = number of tickets
3.25x = cost from buying x number of tickets
5 = cost of nachos & coke
10+3.25x+5 = total cost of admission, tickets, and food/drink
10+3.25x+5 = 80 since this is the amount he has in his pocket
---------------
Let's solve for x
10+3.25x+5 = 80
3.25x+15 = 80
3.25x = 80-15 .... subtract 15 from both sides
3.25x = 65
x = 65/3.25 ........ divide both sides by 3.25
x = 20
