Answer:
[tex]-4p^3-3p^2-17p[/tex]
Step-by-step explanation:
Adding a negative number is the same as subtracting a number. Using this logic, we can change the equation to equal this:
[tex]-3p^3+5p^2-2p-p^3-8p^2-15p[/tex]
Combining like terms, we have negative 3p cubed minus another p cubed, which equals negative 4p cubed, we have 5p squared minus 8p squared, which equals negative 3p squared, and we have negative 2p minus 15p, which is negative 17p.

determine which ordered pair is a solution to the system of equations. A. (-2,-1) B. (-1,-2) C. (2,7)
Answers
Answer:
C. (2, 7)
Step-by-step explanation:
It is fairly easy to try the offered points in the equations to see which works.
A. (x, y) = (-2, -1); -4(-2) +2(-1) = 8 -2 = 6; 9(-2) -3(-1) = -18+3 = -15 ≠ -3
__
B. (x, y) = (-1, -2); -4(-1) +2(-2) = 4 -4 = 0 ≠ 6
__
C. (x, y) = (2, 7); -4(2) +2(7) = -8 +14 = 6; 9(2) -3(7) = 18 -21 = -3
(2, 7) is a solution to the system of equations.
_____
If you want to solve the equations, it can work to put each in standard form by dividing out the common factor.
2x -y = -3
3x -y = -1
Subtracting the first from the second gives ...
(3x -y) -(2x -y) = (-1) -(-3)

You buy a sweater that is on sale for 20% off of the original price. The sweater cost $28. What was the original price?
Answers
Answer:
The original price was $50.
Step-by-step explanation:
Your sweater now cost $28 after 20% off.
To find this we need to start with the price you paid ($28). We then use this cost to find the pre-coupon price. Since the coupon affords a 20% discount, that means you pay for 80%. To solve this, simply divide the price you paid by the percentage you paid.
$28/.80 = $35.
Now that we have the pre-coupon price ($35), we can use that to find the original price. Again, we'd want to divide that by the percentage you paid for, which is 70%.
$35/.70 = $50

A certain tiger shark is 55 cm long at birth and grows 2.5 cm / year. A certain hammerhead shark is 25 cm long at birth and grows 5 cm/year. When will the sharks be equal in length?
Let x = time in years
Let y = length of the sea creatures
The equation for the length of the tiger shark is
[ Select ]
. The equation for the length of the spiny dogfish hammerhead shark is
[ Select ]
. Solving with elimination, the sharks will be equal in length when
[ Select ]
years have passed.
Answers
Answer:
Step-by-step explanation:
equation for tiger shark:
for each additional year, it grows by 2.5 cm so that would be shown as 2.5x. also it starts at 55 so you would have to add 55 to that 2.5x.
the equation would be y = 2.5x + 55
equation for hammerhead:
do the same process with the other numbers. this would be
y = 5x + 25
solve with elimination:
subtract the two equations, which would eliminate the y variable
y = 5x + 25
- (y = 2.5x + 55)
you get
0 = 2.5x - 30
solve that for x
2.5x = 30
x = 12 years
so the years that have passed is 12. to find the length, plug in x = 12 into one of the equations:
y = 5x + 25 becomes y = 5 * 12 + 25 = 60 + 25 = 85
so they will be 85 cm long each.

Ethan buys a new phone. It cost 75$. He will pay for this on his 1st bill.
His phone plan charges 0.06 dollars per minute on the phone.
'He has $90 to spend on his 1st bill. How long can he be on his phone to not go over his budget?
Answers
Answer:
250 minutes
Step-by-step explanation:
90-75=15
15/0.06=250
Answer:
x = 250 minutes
Step-by-step explanation:
The equation for this problem can be set up as follows-
Y = 0.06x+75
y = total phone bill
x= number of minutes on his phone
If Ethan can spend a total of $90 maximum, then y = 90
90 = 0.06x +75 solve for X to determine how many minutes he can be on his phone to reach a $90 total.
x = 250 minutes

nineteen students named lacrosse as there favorite sport. explain how to use the circle graph for the total number of students? 20% chosr swimming 42% chose volleyball and 38% chose laccrosse
Answers
The total number of students is 50
The number of students that named lacrosse as their favorite sport is given as:
[tex]Lacrosse = 19[/tex]
From the circle graph, 38% chose lacrosse.
So, the proportion of students that represent lacrosse is:
[tex]Lacrosse = 38\% \times Students[/tex]
Substitute 19 for lacrosse
[tex]19= 38\% \times Students[/tex]
Multiply both sides by 100
[tex]1900 = 38 \times Students[/tex]
Divide both sides by 38
[tex]50 = Students[/tex]
Rewrite as:
[tex]Students = 50[/tex]
Hence, the total number of students is 50

Answers
The ratio as a unit rate is 0.8 meters per second.
What is a Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
The given statement is "8 meters in 10 seconds".
It can be written as:
= 8/10 meters per second
= 0.8 meters per second
