The graph represents the cost y (in dollars) to open an online gaming account and buy x games. Find the slope and the y-intercept of the line.
Answers
Answer:
Slope = 0.1 or 1/10
Y-int. = 15
Step-by-step explanation:
We have points (0,15), (3,45), (6,75), and (9,105).
slope is rise over run, or rise/run.
So, 9-3/105-45=6/60
now, simplify 6/60.
6/60=1/10 or 0.1
We already have the y-intercept, (0,15), because that's what intercepts the y-axis.
The slope of the line is 10.
The y-intercept of the line is 15.
Locate two points on the graph, choosing points whose coordinates are integers. We will use (3, 45) and (9, 105).
Starting with the point on the left, (3, 45) going from the first point to the second point, (9, 105).
The rise on the vertical leg of the triangle = (105 - 45) = 60
The run on the horizontal leg of the triangle = (9-3) = 6
Use the slope formula.
[tex]m = \frac{rise}{run}[/tex]
[tex]m=\frac{60}{6} =10[/tex]
The slope of the line is 10.
The y-intercept of a graph is the point where the graph crosses the y-axis. (Because a function must pass the vertical line test, a function can have at most one y-intercept.
the y-intercept of the line is 15.
Therefore, The slope of the line is 10 and the y-intercept is 15.

The HCF of two numbers is 20. The LCM of both numbers is a multiple of 14. One number is greater than the other, work out the smallest possible values of both numbers.
Answers
Answer:
The smallest combination of the numbers is 20 and 140
Step-by-step explanation:
The given parameters are;
The Highest Common Factor HCF of the two number = 20
The Lowest Common Multiple LCM of both numbers = Multiple of 14
Let x and y represent the two numbers, we are given;
x > y
We have;
[tex]L.C.M. = \dfrac{Product \ of \ the \ numbers}{H.C.F.}[/tex]
Substituting the known values, we have;
[tex]x \times 14 = \dfrac{Product \ of \ the \ numbers}{20}[/tex]
The product of the numbers = x × 14 × 20
The possible products of the numbers are;
280, 560, 840, 1,120, 1,400, 1,680, 1,960, 2,240, 2.520, 2,800, 3,080, 3,360, 3,640, 3,920
Dividing the possible products by 20 gives, the smallest quotient that is also a multiple of 20 as 140, from which we have;
20 × 140 = 2,800
Therefore, the smallest combination of the numbers = 20 and 140.

Leanna opens a savings account with an initial balance of $100. She then
deposits $50 each month. She currently has $450. How many months has she
been saving for?
Answers
Answer:
7
Step-by-step explanation:
450-100=350
350/50=7
7 months
Leanna has been saving for 7 months to have the balance of $450.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as linear equation in one variable.
Let's suppose the Leanna has been saving the money for 'x' months
It means total months = x
Intial balance = $100
Each month she deposit = $50
After x months she will have = $450 (with initial balance)
We can frame a linear equation in one variable such that:
50x = 450 - 100 (without initial balance)
50x = 350 (divide by 50 on both sides)
x = 7 months
Thus, Leanna has been saving for 7 months to have the balance of $450.

Factor 5x^2-11x+6. Rewrite the trinomial with the X-term expanded using 2 factors
The answer starts as 5x^2_______+6
Answers
Answer:
[tex]5x^2-5x-6x+6[/tex]
Step-by-step explanation:
[tex]5x^2-11x+6\\5x^2-5x-6x+6[/tex]
we need to factorize it so the X-term expanded should satisfy two conditions
1) +5 times +6 should be +30
2) add or subtract any two numbers which multiply and give -11
so here -5 times -6 gives +30 and -5 added to -6 equals -11
A book is on sale for 30% off. The sale price of the book is $14. What is the original price of the book
Answers
Since $14 is the price after a 30% discount then $14 is 70% of the original price.
$14/70=x/100 (100% would be the original price)
1400=70x or 1400/70 = $20!
You can double check the work by taking 30% off the $20 (10% would be $2, 30% would then be $6) 20-6=14!

Suppose you want to put a frame around the painting shown at the right. The frame will be the same width around the entire painting. You have 276 in.2 of framing material. How wide should the frame be?
Answers
Answer:
The frame should be 36 + 2b + 16 + 2b
Step-by-step explanation:
To solve this question, let assign 36 in x 16 in as the dimension of the painting.
276 in^2 is the area of the framing material to be used.
Let the width of the frame around the frame be "b", thus; the dimension of the frame is 36 + 2b + 16 + 2b

Answers
Answer:
well, 11 days
Step-by-step explanation:
if you were to put take out the y and put 2600 in the y place (2600=235x+15)
you solve that, and will come to 11 days
further explaining:
2600-15 = 2585
2585 / 235 = 11
( I'm not sure if this is right, the question is worded weird and almost doesn't make sense)
but I think it is looking for substitution
Hope this helps!
Answer:
I am given a number of cans, which is y, and I need to find the number of days, which is x. To do this, I would substitute 2600 for y, to get 2600 = 235x + 15. Solving for x, I would get x = 11. Thus, it would take 11 days to collect 2600 cans.
