Answer:
y = 3x - 11
Step-by-step explanation:
First, use the y2-y1/x2-x1 format to find the slope: 20 - 5/3 - (-2)(Note: change 3 - (-2) to 3 + 2 to make it easier for you)
Simplify 15/5.Your slope would be 3/1 or 3.
Now use the slope-intercept format: y = mx + b(Use either the first point or second point, I chose the first)
5 = 3(-2) + b
Multiply 3 and -2, which is -6.Subtract 5 from -6: -6 - 5 = -11Your y-intercept is -11.
Hope this helped!

Two friends decide to rent an apartment and split the cost evenly. They each paid $752 towards the total move in cost which included first and last month’s rent and a security deposit of $499. What will be the cost of rent per month for each of them?
Answer:
They will both pay $63.50 a month
Step-by-step explanation:
Since they paid $752 total and $499 as a security deposit, you subtract the two, getting you $253 in rent for both months. Divide that answer by 2 to get $126.5 to get how much they payed each month together, then divide by 2 again to get how much they each payed which is $63.50

Mr. Quick bought a new computer system. The regular price was $1850, but he got a 15% discount. How much did he pay?
Answer:
the price Mr. Quick paid is=$1343
I think I can help you with this
you can easily solve this by using a rule of three
Step one
find the discount value if
$1580⇒ 100%
$x? ⇒ 15%
do the relation
the discount is $237
the price Mr. Quick paid is
the price Mr. Quick paid is=regular price - discount
the price Mr Quick paid is=$1580-$237
the price Mr Quick paid is=$1343
I hope it helps, Have a great day!!! :)

PLEASE HELP SIMPLE NTH TERM
So, i need to find out the nth term of the sequence
25 20 15 10 5
Please help quickly i will give brainliest
Answer:
-5n + 20
Step-by-step explanation:
n stands for the term number so if you want to find the 50th term all you have to do is substitute n with 50
first of all find the difference between each number in the sequence
the difference between 25 and 20 is -5
the difference between 20 and 15 is -5
the difference between 15 and 10 is -5
the difference between 10 and 5 is minis -5
because
25-5=20
20-5=15
15-5=10
10-5=5
now that you know the the difference you place the number in front of n like this
-5n
to find the rest all you need to do is use the difference between each number which is -5 and do it on the first number
so 25 - 5
this gives 20
so our nth term is -5n + 20
if you still don't get i can re-explain it to you

The population of a certain species of insect is given by a differentiable function P , where P(t) is the number of insects in the population, in millions, at time t , where t is measured in days. When the environmental conditions are right, the population increases with respect to time at a rate that is directly proportional to the population. Starting August 15, the conditions were favorable and the population began increasing. On August 20, five days later, there were an estimated 10 million insects and the population was increasing at a rate of 2 million insects per day. Which of the following is a differential equation that models this situation?
a. P=2(tâ5)+10
b. dP/dt=2/5t
c. dP/dt=1/5P
d. dP/dt=5P
Answer:
Option C, dP/dt=1/5P
Step-by-step explanation:
The change is population of insects is directly proportional to the rate of change of population
Hence,
[tex]\frac{dP}{dt} \alpha P[/tex]
Or [tex]\frac{dP}{dt} = kP[/tex]
where K is the proportional constant
We will find the value of k
Keeping the given values of rate of change of population and population in above equation, we get -
[tex]\frac{2}{10} = k\\k = \frac{1}{5}[/tex]
Hence,
[tex]\frac{dP}{dt} = \frac{1}{5} P[/tex]

describe the process of solving a proportion.
The process of solving a proportion is given below.
We are given that;
To show the process of solving a proportion
Now,
A proportion is an equation that states that two ratios are equal. For example, if we have 2 4 = 3 6[tex]{\\displaystyle {\\frac {2} {4}}= {\\frac {3} {6}}}[/tex] , then we have a proportion.
To solve a proportion, we need to find the value of a missing term that makes the equation true. There are different methods to solve a proportion, but one common method is cross-multiplication. Here are the steps to solve a proportion by cross-multiplication:
Multiply the numerator of one ratio by the denominator of the other ratio.
For example, if we have 2 4 = x 6
[tex]{\\displaystyle {\\frac {2} {4}}= {\\frac {x} {6}}}[/tex] , then we multiply 2 by 6 and get 12.
Multiply the denominator of the first ratio by the numerator of the second ratio.
For example, if we have 2 4 = x 6
[tex]{\\displaystyle {\\frac {2} {4}}= {\\frac {x} {6}}}[/tex] , then we multiply 4 by x and get 4x.
Set the two products equal to each other. For example,
if we have [tex]2 4 = x 6 {\\displaystyle {\\frac {2} {4}}= {\\frac {x} {6}}}[/tex], then we set 12 = 4x.
Solve for the missing term. For example, if we have 12 = 4x, then we divide both sides by 4 and get x = 3.
Check your answer by plugging it back into the original proportion.
For example, if we have x = 3, then we plug it back into 2 4 = x 6 [tex]{\\displaystyle {\\frac {2} {4}}= {\\frac {x} {6}}}[/tex] and get 2 4 = 3 6
[tex]{\\displaystyle {\\frac {2} {4}}= {\\frac {3} {6}}}[/tex] , which is true.
Therefore, by proportion answer will be given below.

what is the percent change of 2880 to 3168
Answer:
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
10% = 10/100 = 10 ÷ 100 = 0.1.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 10% of its value.
Percentage increase = 10% × 2,880
New value =
2,880 + Percentage increase =
2,880 + (10% × 2,880) =
2,880 + 10% × 2,880 =
(1 + 10%) × 2,880 =
(100% + 10%) × 2,880 =
110% × 2,880 =
110 ÷ 100 × 2,880 =
110 × 2,880 ÷ 100 =
316,800 ÷ 100 =
3,168
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 2,880 =
3,168 - 2,880 =

There is a TV that is $189.00. There is a coupon offering 15% off any television purchase. If the sales tax on the TV is 8%, how much will the TV cost total?
Answer:
175.77 dollars
Step-by-step explanation:
15% off 189.00 is 160.65 then you take that answer and add on the sales tax from the original price. Doing 189.00 x 8 percent gets you 15.12 dollars.
Add 160.65 + 15.12 to get 175.77 dollars.

Since the perimeter of a rectangle is 2(l + w), where l is the length and w is the width, the perimeter of this rectangle would be
2((y + 5) + y)
To simplify this, just add similar terms inside the parentheses and multiply them both by 2.

(g+4)=65
g=65-4
g=61degrees
The value of each variable in the parallelogram:
h = 9 and g = 61°.
What is parallelogram?A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.
Given:
The shape is a parallelogram.
That means, the opposite sides are parallel and equal.
16 - h = 7
h = 16 - 7
h = 9
And opposite angles of a parallelogram are also equal.
g+4 = 65
g = 65 - 4
g = 61°
