Dev ordered 10 ink cartridges and 1 box of copy paper for his office. The box of copy paper cost $45. He had a coupon for $2 off each ink cartridge. He spent a total of $175.
Based on the cost of the copy paper and the discount on ink cartridges, the cost of the ink cartridge is $15 each.
First find the amount paid for the ink cartridges:
= Total spent - cost of copy paper
= 175 - 45
= $130
He got a discount of $2 per cartridge. For 10 cartridges he got a discount of:
= 2 x 10
= $20
The cost of each ink cartridge is:
= (Amount spent on ink cartridges + Discount) / Number of cartridges
= (130 + 20) / 10
= $15 each
In conclusion, each cartridge cost $15.

Graph y+6=45(x+3) using the point and slope given in the equation. Use the line tool and select two points on the line.
Answer:
Step-by-step explanation:
We are given the equation y+6 = 45(x+3).
On simplifying the equation we get,
y+6 = 45x + 45×3
i.e. y+6 = 45x + 135
i.e. y = 45x + 129.
Now, x = 0 gives y = 129 and y = 0 gives x = -2.867.
The general form of a straight line is given by y = mx + c, where m is the slope and c is the y-intercept.
So, on comparing, the slope of given equation is m = 45.
Plotting this straight line y = 45x + 129 on the graph gives the following figure.
The two points selected on the graph are (0,129) and (-2.867,0).

Find the value of k, if g(x) = f(x) + k. F(x)=|x|
g(x)=|x|-4.
Answer:
k=-4
Step-by-step explanation:
g(x) = f(x) + k
|x|-4 = |x| +k
then, cut the |x| in two sides
-4=k
k=-4
Which pairs of points have lines passing through them with a slope of 2/3?
Answer:
(0,0) and (3,2)
(1,5) and (4,7)
(-2, -2) and (4, 2)
Step-by-step explanation:
The first option will have a slope of 3-0 over 2-0, which is 1.5, which is incorrect.
The second option will have a slope of 2-0 over 3-0, which is 2/3, and is correct.
The third option will have a slope of 7-5 over 4-1 which is 2/3, and is also correct.
The fourth option has a slope of 2+2 over 4+2, which is 2/3, and is correct.
The fifth option has a slope of -30-30 over -20-20, which is also 1.5, and is incorrect.
Therefore, the middle three options are correct.
Pairs of points have lines passing through them with a slope of 2/3 are (0,0) and (3,2), (1,5) and (4,7) , and (-2,-2) and (4,2)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We need to find pairs of points have lines passing through them with a slope of 2/3
(0,0) and (2,3)
m=3/2 which is not equal to 2/3
Hence it is not passing through these points.
(0,0) and (3,2)
m=2/3 which is equal to 2/3
it is passing through (0,0) and (3,2)
(1,5) and (4,7)
m=7-5/4-1=2/3 which is equal to 2/3
it is passing through (1,5) and (4,7)
(-2,-2) and (4,2)
m=2+2/4+2=4/6=2/3 which is equal to 2/3
it is passing through (-2,-2) and (4,2)
(20,30) and (-20, -30)
m=-30-30/-20-20=-60/-40=3/2
Hence pairs of points have lines passing through them with a slope of 2/3 are (0,0) and (3,2), (1,5) and (4,7) , and (-2,-2) and (4,2)

If 4 gallons of milk cost $16.24, how much would 7 gallon of milk cost
Answer:
$28.42
Step-by-step explanation:
First let's calculate the cost per gallon.
We can do this by simply dividing the cost of 4 gallons by 4
1 gallon of milk cost 16.24/4 = 4.06
We want to find the cost of 7 gallons.
We can easily do this by multiplying the cost of one gallon by 7
7 gallons of milk cost 7 * 4.06 = $28.42

Percent of 51,300-45,800
Answer: the percent is 112.01. please mark brainliest
Step-by-step explanation:
Help please, it's due tomorrow
Step-by-step explanation:
a)
she makes $44,600 per year.
that is rounded $3,716.67 per month.
the net monthly income is $2,415, so she has rounded deductions of
3716.67 - 2415 = $1,301.67
that is $15,620 per year.
100% = $44,600
1% = 100%/100 = $446
how many % ? that is how often 1% fits into the amount.
15620 / 446 = 35.02242152...%
b)
in 6 months she wants to save $1,800.
that means
1800/6 = $300 per month.
100% = $2,415
1% = $24.15
how many % ?
300 / 24.15 = 12.42236025...%
c)
I guess, the question is really, how much savings she accumulated then in 6 months after the raise.
so, after the raise, she makes now
2415 + 96.60 = $2,511.60
100% = $2,511.60
1% = $25.116
12.4223...% = 1%×12.4223... = 25.116×12.4223... = $312
in 6 months she has then saved
312×6 = $1,872

What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
[tex]y=-\frac{1}{4}x\\[/tex]
Step-by-step explanation:
The slope is calculated by "up ÷ across".
= -1 ÷ 4
= [tex]-\frac{1}{4}[/tex]
The y-intercept is just 0 (because the line meets at the y axis at 0).
So, using [tex]y=mx+b[/tex] (where m = slope and b = y-intercept),
[tex]y=-\frac{1}{4}x+0[/tex]
but the '+0' is unnecessary so we just say [tex]y=-\frac{1}{4}x[/tex]
