Standard form:x^2-2x-48=0
I think x=8, -6
Solve the equation.
4n−18=5
Answer:
n = 5.75
Step-by-step explanation:
4(5.75) - 18 = 5
4(5.75) = 23
23 - 18 = 5
Therefore, n = 5.75.
Hope this helps:)

What is the correct answer for both?
Answer:
14) C (-2, 4)
15) D (-3, -3)
Step-by-step explanation:
-6x + 4y = 28
6x + 9y = 24
-6x + 4y = 28
4y = 28 + 6x
y = 7 + 1.5x
6x + 9y = 24
6x + 9(7 + 1.5x) = 24
6x + 63 + 13.5x = 24
19.5x + 63 = 24
19.5x = -39
x = -2
-6x + 4y = 28
-6(-2) + 4y = 28
12 + 4y = 28
4y = 16
y = 4
____________
4x - 4y = 0
-4x + 3y = 3
4x - 4y = 0
4x = 4y
x = y
-4x + 3y = 3
-4(y) + 3y = 3
-4y + 3y = 3
-1y = 3
y = -3
4x - 4y = 0
4x - 4(-3) = 0
4x + 12 = 0
4x = -12
x = -3

Answer:
([tex]\frac{2}{3}[/tex], 2 )
Step-by-step explanation:
Given the 2 equations
3x + [tex]\frac{1}{2}[/tex] y = 3 → (1)
6x - y = 2 → (2)
Multiplying (1) by - 2 and adding to (2) eliminates the term in x, that is
- 6x - y = - 6 → (2)
Add (2) and (3) term by term to eliminate x
- 2y = - 4 ( divide both sides by - 2 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (2)
6x - 2 = 2 ( add 2 to both sides )
6x = 4 ( divide both sides by 6 )
x = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
Solution is ( [tex]\frac{2}{3}[/tex], 2 )
The morning low tide at the beach is 12 inches. After 6 hours, the afternoon high tide is 57 inches. What is the average number of inches the tide changed per hour?
Answer:
7.5 inches per hour
Step-by-step explanation:
Given that:
Morning low tide at beach = 12 inches
Afternoon tide after 6 hours = 57 inches
Average number of inches tide changed per hour :
(Afternoon tide - morning tide) / number of hours
(57 inches - 12 inches) / 6 hours
45 inches / 6 hours
= 7.5 inches per hour
there is your answer. hope this helps

Find the slope of the line that passes through (9, 8) and (6, 13).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
-5/3
Step-by-step explanation:
Answer:
slope: -1.6666666
Step-by-step explanation:
Use the formula m=(y2-y1)/(x2-x1)
Substitute values: m=(13-8)/(6-9)
Solve that, and you will find m (slope) = -1.666666

For Spirit Day, each 8th-grade homeroom designs a unique twocolor T-shirt. They get to choose from the colors red (R), blue (B), green (G), violet (V), and orange (O). Each T-shirt is a solid color with a different color used for the student's name. What is the probability that a homeroom will have a T-shirt with a combination of blue and violet?
Answer:
P(B and V)=10%
Step-by-step explanation:To solve this poroblema we use the formula of combinations:
C(n,r)=(nr)=n!(r!(n−r)!)
Where n is the number of objects that can be chosen and you choose r from them.
There are 5 colors of shirts.
The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:
5C2= [tex]\frac{5!}{2!(5-2)!}[/tex]
5C2=10
The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:
2C2=1
Then the probability is:
P( B and V)= [tex]\frac{1}{10}[/tex]
=0.1= 10%
[tex]\frac{2C2}{5C2}[/tex]
Answer:
P( B and V)=10%

Your friend, Broseph, recently graduated from the University of Bros. During his last semester he passed "Introduction to Brotistics with an Emphasis on Tinder Applications". His final project required that he use the Binomial Distribution to calculate the probability of going on a date with more than half of his next 20 Tinder matches.
Broseph found that he had a 64% chance of going on a date with any given Tinder match from historical data.
Broseph should use the ____________ to calculate the probability. Since he is calculating the probability of going on dates with more than half of his next 20 matches--the number of successes is ________ , n = ________ , and p = ______ .
Broseph has a __________ chance of going on dates with at least half of his next 20 Tinder matches. Round the answer to nearest tenth as a percentage i.e. 14.2%.
Answer:
I need to know the net percentage to to calculate the quadratic function

Bacteria doubles every 10 minutes. If you start with 2 bacteria in a petri dish, how many bacteria will there be after 40 minutes?
Answer: I think the answer is 32 bacteria after 40 minutes.
Step-by-step explanation:
I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

Will runs a business that employs 105 staff.
Each member of staff works 35 hours a week and gets an hourly wage of £7.60
The staff have complained that they are not being paid enough and have asked
for a 10% pay rise.
How much will the proposed pay rise cost Will on a weekly basis?
£
Each employee makes 35 x 7.60 = 266 per week.
105 employees x 266 = 27,930 per week total pay.
27930 x 10 % = 27930 x 0.10 = 2,793 more per week.
