Answer:
y = - [tex]\frac{5}{2}[/tex] x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (2, 0)
m = [tex]\frac{0+5}{2-4}[/tex] = [tex]\frac{5}{-2}[/tex] = - [tex]\frac{5}{2}[/tex] , then
y = - [tex]\frac{5}{2}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 0 )
0 = - 5 + c ⇒ c = 0 + 5 = 5
y = - [tex]\frac{5}{2}[/tex] x + 5 ← equation of line

The cylinder has a volume of 12pi cubic inches and a diameter of 4 inches. Find the cylinders radius and height. The cylinders radius is______ inches and it’s height is_____ inches.
Answer:
The cylinder's radius is 2 inches and it’s height is 3 inches.Step-by-step explanation:
A diameter is two radiuses long, so the cylinder's radius is:
R = 4 in ÷ 2 = 2 in
The volume of cylinder is: V = πR²×H
Therefore:
12π = π×2²×H
12 = 4H
H = 3 in

Find the measure of the missing angles.
Answer:
b = 20, c = 160
Step-by-step explanation:
b and 20 degrees are vertical angles, so they are equal.
b (20 degrees) and c are on a line together, so they add up to 180. 180 - 20 = 160 degrees

PLEASEE HELP ILL GIVE BRAINLIEST
Answer: 2025
Step-by-step explanation: first you multiply 30x15x9= 4050 but you keep going and then divide 4050/2= 2025 and that would be your answer
A=2025
The volume of the right triangular prism in cubic fee should be considered as the 2025.
Calculation of the volume of the right triangular prism:here first we have to multiply the 30, 15 and 9 with each other so it comes 4050
Now we have to half the 4050 so it comes 2025
hence, The volume of the right triangular prism in cubic fee should be considered as the 2025.

Ty'Lil has $220 to spend on a membership to a new gym. The monthly fee is $15 and he must also pay $40 to join. How many months can he afford?
Answer: 12
Step-by-step explanation:
220-40=180
180/15=12
Answer:
11 months
Step-by-step explanation:
220 -40=180
Since you have to pay $40 to join you have to add $15 to that $40 for the monthly fee.
220-40-15=156
^ This equals one month worth of the membership.
220-40-15-15-15-15-15-15-15-15-15-15-15=0
So add up all the 15s and you have the number of months Ty ´Lil can afford.
I hope this makes sense.

Brett has a 30 year fixed rate mortgage for $112500 with monthly payments of $603.92. The annual interest rate is 5% what is the total cost of the principal and interest for this not rounded to the nearest dollar
Answer:
a. Total cost of the principal = $217,411.20
b. Interest for the mortgage loan = $104,911.20
Step-by-step explanation:
Total cost of the principal = Monthly payment * Number of years * Number of months in a year = $603.92 * 30 * 12 = $217,411.20
Total cost of the principal of the loan includes the mortgage loan amount and the interest for the mortgage loan. Therefore, the interest for the mortgage loan can be calculated as follows:
Interest for the mortgage loan = Total cost of the principal - Mortgage loan amount = $217,411.20 - $112,500 = $104,911.20
Tickets to the school play are $10 for adults, $4 for students and $3 for senior citizens. There were 670 tickets sold for Thursday's show, worth $5615. If there were 65 tickets sold to senior citizens, how many tickets were sold to adults and how many were sold to students?
Answer:
500
105
Step-by-step explanation:
This question would be solved using a simultaneous equation
let
a = number of adults who bought the ticket
b = number of students who bought the ticket
c = number of senior citizens who bought the ticket
a + b + c = 670 eqn 1
10a + 4b + 3c = 5615 -- eqn 2
If 65 senior citizen bought the ticket, substitute for c in equation 1 and 2
a + b + 65 = 670
a + b = 670 - 65
a + b = 605 eqn 3
10a + 4b + 3(65) = 5615
10a +4b = 5420 eqn 4
multiply equation 3 by 10 to derive equation 5. Subtract eqn 4 from eqn 5
10a + 10b = 6050 eqn 5
-
10a + 4b = 5420 eqn 4
= 6b = 630
b = 105
Students who bought the ticket are 105
Substitute for b in eqn 3
a + 105 = 605
a = 500
Adults who bought the ticket are 500

The direct distance from a starting point to a finish line is 15 miles. Unfortunately, you can't take the direct route. If you travel 12 miles east, how many miles north must you travel to reach the finish line? 10 19 9
Answer:
9 miles
Step-by-step explanation:
From Pythagoras :
Opposite^2 = Hypotenus^2 - Adjacent^2
The direct route = 15 miles = hypotenus
x² = 15^2 - 12^2
x² = 225 - 144
x² = 81
x =. Sqrt(81)
x = 9
Hence, you must travel 9 miles north
Answer:
9 miles :)
Step-by-step explanation:
a^2 + 12^2 = 15^2
a^2 + 144 = 225
a^2 = 81
a = 9

Answer:
[tex] \dfrac{-7600}{3} [/tex]
Step-by-step explanation:
The plane is descending, so the change in height is a negative change.
rate of descent = (change in height)/time
rate of descent = (new height - old height)/time
rate of descent = (7400 ft - 15000 ft)/(3 min)
rate of descent = (-7600 ft)/(3 min)
Answer: [tex] \dfrac{-7600}{3} [/tex]
how do i calculate the range? {mean, median, mode, range} pls help ASAP
Also, can you tell me in the comments how to delete an answer or remove it?
Answer:
The anwer is below.
Step-by-step explanation:
To calculate mean a.k.a average of something is when you add all of the numbers in the set and then multiply by the number of numbers there were.
an example : 4, 5,6,7 = 4+ 5 + 6 + 7 + 3 = 25 divided by 5 ( the number of numbers there were ) which is 5 so the mean is 5
To calculate the median you have to organize the set of numbers from least to greatest choose the middle number and that's the median, If there is an even number of numbers in the set then you add the two middle numbers and divide it by 2.
an example : 5,7, 8, 4 = 4, 5, 7 , 8 = the middle numbers = 5 + 7 = 12 divided by 2 = 6
To calculate the mode you have to see which numbers comes more often in the set of numbers, If there are two different numbers that come often even if one is higher include them in the mode.
An example - 5,6,6,6,6,7,7,7. The mode in this is 6 but 7 comes often to so if your teacher tells you to include more than one mode in these kinds of situation you include 7 or in general you don't have to
To calculate the range you choose the greatest and the lowest numbers and substract the highest to the lowest number in the set.
An example 5, 6, 7 , 9 , 8 = 9 ( the highest number in this set) - ( substraction) 5 ( the lowest number in this set) and 9 - 5 = 4 so the range is 4

How? (2x^2 - 3x - 4)(x + 7)
Answer:
[tex]2 {x}^{3} + 11{x}^{2} - 25x - 28[/tex]
Step-by-step explanation:
Using foil method, Multiply the first term
[tex]2 {x}^{2} \times x = 2 {x}^{3} [/tex]
Next, Multiply the Outer term in each parenthesis. (2x^2 and 7
[tex] 2 {x}^{2} \times 7 = 14 {x}^{2} [/tex]
[tex] 2 {x}^{2} \times 7 = 14 {x}^{2} \: \: \: 3x \times - x = - 3x[/tex]
Then, Multiply the Inner Terms (-3x,-4,7) in each parenthesis
[tex] - 3x \times 7 = - 21x[/tex]
[tex] - 4 \times x = - 4x[/tex]
Then multiply the last term (-4 and 7).
[tex] - 4 \times 7 = - 28[/tex]
Combine it you have
[tex]2 {x}^{3} + 14 {x}^{2} - 3 {x}^{2} - 21x - 4x - 28[/tex]
which simplify to
[tex]2 {x}^{3} + 11 {x}^{2} - 25x - 28[/tex]
