Answer:
-(x^2 - 9 x + 3)
Step-by-step explanation:
Simplify the following:
-(-5 x^2 - 9 x + 8) - 6 x^2 + 5
Factor -1 out of -5 x^2 - 9 x + 8:
--(5 x^2 + 9 x - 8) - 6 x^2 + 5
(-1)^2 = 1:
5 x^2 + 9 x - 8 - 6 x^2 + 5
Grouping like terms, 5 x^2 - 6 x^2 + 9 x - 8 + 5 = (-6 x^2 + 5 x^2) + 9 x + (5 - 8):
(-6 x^2 + 5 x^2) + 9 x + (5 - 8)
5 x^2 - 6 x^2 = -x^2:
-x^2 + 9 x + (5 - 8)
5 - 8 = -3:
-x^2 + 9 x + -3
Factor -1 out of -x^2 + 9 x - 3:
Answer: -(x^2 - 9 x + 3)
In Hawaii, January is a favorite month for surfing since 60% of the days have a surf of at least 6 feet.† You work day shifts in a Honolulu hospital emergency room. At the beginning of each month you select your days off, and you pick 6 days at random in January to go surfing. Let r be the number of days the surf is at least 6 feet.
Answer:
3 days.
Step-by-step explanation:
Based on the information provided we see that roughly 60% of the days in January have 6ft+ waves then we would need to use this value to calculate the number of days that are good for surfing. We calculate this by multiplying the number of days that you can surf by 60% using the equation below as r being the actual total amount of days....
r = 6 * 0.60%
r = 3.6
As we can see that there are roughly 3 days that see this amount of wave activity between the 6 chosen dates. We have to round down because we are talking about full days and 3.6 does not meet a fourth full day.

Step-by-step explanation:
since the domain of the function is given, you just have to plug in the numbers to the function:
13x - x²
it's basically asking: if x was any of the numbers in the given domain, what would it be the answer be?
for example:
I'll solve for -2 and you can do the rest.
13 • -2 -(-2 ²) =
13 • 2 + 4 =
26 + 4 = 30
so the range for -2 would be 30
∠A and \angle B∠B are supplementary angles. If m\angle A=(4x-30)^{\circ}∠A=(4x−30)
∘
and m\angle B=(4x-14)^{\circ}∠B=(4x−14)
∘
, then find the measure of \angle A∠A.
Answer:
the measure of ∠A. is 87∘
Step-by-step explanation:
Two angles are said to be supplementary angles if the sum of those angles is 180 degrees.
_________________________________________________
Given
∠A=(4x−30) ∘
∠B=(4x−14) ∘
Fir angles to be supplementary
∠A + ∠B = 180
(4x−30) ∘ + (4x−14) ∘ = 180∘
(8x -54 )∘ = 180∘
=> 8x = 180∘ + 54∘= 234∘
=> x = 234∘/8 = 29.25∘
Thus,
∠A=(4x−30) ∘
∠A=(4*29.25−30) ∘ =( 117 - 30 ) ∘ = 87∘
Thus,
the measure of ∠A. is 87∘
. Three out of four students in school have at least one sibling. If there are 300 students in your school, how many would have at least one sibling?
Answer: 225 students would have at least one sibling.
Step-by-step explanation:
Three out of four is the same as 3/4 meaning that if there are 300 students in your school then 3/4 times 300 will give the number of students with at least one sibling.
3/4 * 300 = 225
This means 225 students would have at least one sibling.
1. The total cost in dollars to buy uniforms for the players on a volleyball team can be
found using the function c = 34.95u + 6.25, where u is the number of uniforms
bought. If there are at least 8 players but not more than 12 players on the volleyball
team, what is the domain of the function for this situation?
The domain will be the integer numbers between 8 and 12 using the limits in other words 8 ≤ u ≤ 12
this is considering every player will bought only one uniform for the season
Hope this helped!
if thats not it read this and see if this works out
The domain of the function is
Step-by-step explanation:
Given : The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function c= 34.95u +6.25, where u is the number of uniforms bought.
If there are at least 8 players but not more than 12 players on the volleyball team.
To find : What is the domain of the function for this situation ?
Solution :
The total cost in dollars c= 34.95u +6.25
Where, u is the number of uniforms bought.
Now, The number of uniforms bought depend on the number of players.
We have given that, there are at least 8 players but not more than 12 players on the volleyball team.
i.e, The number of players are between 8 to 12.
So, The domain of the function is
8< u < 12

Question:
A recipe says to use 3.5 cups of flour to make 48 cookies. What is the constant of proportionality that relates the number of
cookies made, y, to the number of cups of flour used, x Round your answer to the nearest tenth
es -
HELP ASAP
Answer:
13.7 cookies per cup
Step-by-step explanation:
Here, we want to write the constant of proportionality that relates the number of cookies to the
number of flours.
What we do
simply here is to divide the number of cookies by the number of cups of flowers
That would be;
y/x = 48 cookies/3.5 cups = 13.7 cookies per cup

the length of a side of a square is 8x+4.If the perimeter of the square is 80 inches, what is they value of x?
Answer:
Step-by-step explanation:
Note: Perimeter = sum of all the lengths of the shape.
In the case of a square, since all the sides are equal.
This means that if one side = 8x + 4, the perimeter would be 4 times 8x+4 since there are 4 equal sides in a square.
Perimeter = 4 ( 8x + 4)
Perimeter = 32x + 16
We also get told in the question that the perimeter = 80 inches.
Meaning that:
32x + 16 = 80
From here we can solve for x.
Subtract 16 from both sides:
32x = 80 - 16
32x = 64
Divide both sides by 32 to solve for x.
x = 64/32 = 2
Finding the Area of a Triangle
Answer: 1, 3, 6
Step-by-step explanation:
Determine the 50th term in the sequence defined by an = -11+ 5(n − 1).
The 'nth' term is a formula with 'n' in it which enables you to find any term of a sequence without having to go up from one term to the next. 'n' stands for the term number so to find the 50th term we would just substitute 50 in the formula in place of 'n'.
