[tex]\huge\boxed{y=\frac{1}{4}x + \frac{13}{4}}[/tex]
Step-by-step explanation:
In order to find the equation to this line, we need to note that we see two points on this graph. Using these two points, we can use them to find the slope of the graph and use one to find the y-intercept.
We know that the slope of a line is defined by [tex]\frac{\Delta y}{\Delta x}[/tex] (change in y / change in x). Therefore, we can use our two points that we know - (-5, 2) and (3, 4) to find the slope.
The change in y is [tex]4 - 2 = 2[/tex], and the change in x is [tex]3 - (-5) = 3+5= 8[/tex]. Therefore, our slope is [tex]\frac{2}{8} = \frac{1}{4}[/tex].
Now that we know our slope, our equation in slope-intercept form looks something like this.
[tex]y = \frac{1}{4}x + b[/tex]
However, we still have b to solve for. We can solve for this by substituting a point we already know into the equation. Let's substitute (3, 4) inside.
[tex]4 = \frac{1}{4} \cdot 3+b[/tex] [tex]4 = \frac{3}{4} + b[/tex] [tex]b = \frac{16}{4}- \frac{3}{4}[/tex] [tex]b = \frac{13}{4}[/tex]So now we know that the y-intercept is [tex]\frac{13}{4}[/tex]. Plugging that into our equation finishes it off, leaving our final equation to be [tex]y = \frac{1}{4}x + \frac{13}{4}[/tex].

Answers
Step-by-step explanation:
Hey there!
Given;
The sum of two numbers is 45.
One of them is 27.
Let next number is "x".
So, Add "x" and "27" and show it is equal to 45.
Or, x+27 = 45
Therefore, x+27 = 45 is the required equation.
Now, solving unknown number.
~ Take "27" to right side and subtract it.
x= 45 - 27
X= 18
Therefore, next number is (x) = 18.

A taxi service charges a base fee of $5.00 for each fare. In addition, the service charges a $1.75 per minute fee. Which equation relates the total cost of a fare, , to the length of the ride, in minutes, ?
Answers
Answer:
Equation is = 5+1.75m
Step-by-step explanation:
Given that,
A taxi service charge is $5.00 for each fare.
In addition, the service charges a $1.75 per minute fee.
It means, for every minute, $1.75 increases with time and $5.00 is fixed.
ATQ,
Total cost = 5+1.75m
Where m is time in minutes
Hence, the required equation is "5+1.75m".
Jennifer received a $25 gift certificate from a music store. She can use it to buy 2 CD’s and 5 cassettes or 1 CD and 15 cassettes. Find the cost of 1 CD and 1 cassette.
Please help A.S.A.P.
Answers
Answer:
CD = 10$
Cassette = 1$
Step-by-step explanation:
ok, time to use some variables
C = CD
S = Cassette
2c + 5s = 25$
1c + 15s = 25$
the second equation has 1 less CD and 10 more Cassettes, therefore 1c = 10s
Now we can calculate how many Cassettes we can buy
1c - 1c = 0c
15s + 10s = 25s
This means that 25s = 25$
therefore 1s = 1$
since we know that 10s = 1c, and 1s = 1$, then we can figure out how many dollars the CD is
1c = 10s = 10$
1c = 10$
Variables are helpful :)

Answer:
Subtracting a number is the same as adding the opposite of the number
Step-by-step explanation:
Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.

(6 - 2)/2 = 4/2 = 2y- intercept is 2Equation for the line is:
y = 2x + 2For the point (40, 76) we can verify with the equation:
40*2 + 2 = 82The point (40, 76) is close the line but the line doesn't pass through it.
Answer:
x | y
0 | 2
2 | 6
4 | 10
6 | 14
Equation of the line is
[tex] \frac{y - 2}{x - 0} = \frac{6 - 2}{2 - 0} \\ \frac{y - 2}{x} = \frac{4}{2} = 2 \\ y - 2 = 2x \\ y - 2x = 2\\ \boxed{y=2x+2}[/tex]
When x=40, y will be (2×40)+2 =82
So the point should pass through (40,82) and not (40,76).

b. 918
c. 775
d. 640
(10 points and brainliest if the answer is right)
Answers
Answer:
A. 1,112
Step-by-step explanation:
The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.
Option A is the correct answer.
What is an expression?
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let's start by finding the profit per chair:
So,
Profit per chair = Selling price - Production cost
= $55.75 - $16.91
= $38.84
Next, we need to determine how many chairs the manufacturer needs to sell to make a profit of $24,850:
Profit = Profit per chair x Number of chairs sold - Overhead costs
$24,850 = $38.84x - $18,340
$43,190 = $38.84x
x = 1,112.49
Rounding to the nearest whole number, the manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.
Therefore,
The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Please help! Lauren is 16, and Cara is 14. Their grandad gives them $1200 to share in the ratio of their ages. How much money do they each get? Show your work, please!!
Answers
Answer:
Lauren will get $640 and Cara will get $560.
Step-by-step explanation:
Given that:
Age of Lauren = 16
Age of Cara = 14
Ratio = 16 : 14
Amount given by their grandad = $1200
Let,
x be the number of times.
16x + 14x = 1200
30x = 1200
Dividing both sides by 30
[tex]\frac{30x}{30}=\frac{1200}{30}\\x=40[/tex]
Share of Lauren = 16x = 16*40 = $640
Share of Cara = 14x = 14*40 = $560
Hence,
Lauren will get $640 and Cara will get $560.
