Answer:
Rs 120
Step-by-step explanation:
Let MP = m
Discount = 25% of MP = m/4
SP = MP - Discount
= m - m/4 = 3m/4
If profit is 20%, CP = 3m/4 x 100/120 = 5m/8
=> Profit = 3m/4 - 5m/8 = m/8
Given Profit - Discount = Rs 15
=> |m/8 - m/4| = 15
m/8 = 15
m = Rs 120
Write, in slope intercept form, the equation of the line that passes through (8, -9) and has a slope of -5/4.
Answer:
The equation in the slope-intercept form will be:
[tex]y=-\frac{5}{4}x+1[/tex]
Step-by-step explanation:
Given
slope = m = -5/4point = (8, -9)As we know that the equation of a line in point-slope form is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = -5/4 and point = (8, -9)
[tex]y-\left(-9\right)=\frac{-5}{4}\left(x-8\right)[/tex]
[tex]y+9=\frac{-5}{4}\left(x-8\right)[/tex]
Writing the equation in slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope, and b is the y-intercept
so the equation of the line in slope-intercept form becomes
[tex]y+9=\frac{-5}{4}\left(x-8\right)[/tex]
subtract 9 from both sides
[tex]y+9-9=\frac{-5}{4}\left(x-8\right)-9[/tex]
[tex]y=-\frac{5}{4}x+1[/tex]
Therefore, the equation in the slope-intercept form will be:
[tex]y=-\frac{5}{4}x+1[/tex]

A construction company uses the function f(x), where x is the number of people working on a project, to model the amount of money it spends to complete a project. What would a reasonable domain be?
All integers
Real numbers
Positive real integers
Positive integers
Answer:
Please use "^" to denote exponentiation: f(x) = x^2 + 3x + 5.
Because this is a polynomial, the domain consists of the set of all real numbers.
Step-by-step explanation:
Answer:
Positive integersStep-by-step explanation:
The domain is the people and the range is the money spent
People would be counted as positive integers, only the last answer choice considers this.
So the answer is:
Positive integersConsider the line y = 3x - 1.
Find the equation of the line that is perpendicular to this line and passes through the point (-8, 3)
Find the equation of the line that is parallel to this line and passes through the point (-8, 3).
Answer:
y = -1/3x + 1/3
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals.
The given line is
y = 3x - 1
This equation is written in the slope-intercept form, y = mx + b, where m is the slope.
slope of given line = m = 3
slope of perpendicular line = -1/3
Now we need the equation of the line with slope -1/3 that passes through the point (-8, 3)
y = mx + b
y = -1/3x + b
3 = (-1/3)(-8) + b
3 = 8/3 + b
9/3 = 8/3 + b
b = 1/3
y = -1/3x + b
y = -1/3x + 1/3
Solve for x if 2(5x + 2)2 = 48.

first one roughly = 35+19+16....then you can see 77 is the closest, even without calcatulor
second one precisely==20+33+5+38.....then you can see that 90 is roughly the closest one, again even without to add those 4 togetherly precisely

7+2x/3=5
7+2x/3=5/1
7+2x(1)=5(3)
7+2x=15
2x=15-7
2x=8
x=4
Answer:
x = 4
Step-by-step explanation:
The goal is to get x by itself.
1. Multiply both sides by 3 and you are left with:
7 + 2x = 15
2. Subtract 7 from both sides and you are left with:
2x = 8
3. Simplify by dividing each side by 2 and you are left with the answer:
x = 4

You are riding a train. Your carry-on bag can weigh no more than 50 pounds. Your bag weighs 38 pounds.
Which inequalities represent how much weight you can add to your bag?
W > 50 - 38
50 > W - 38
38 + w < 50
W < 50 - 38
Can you add both a 9-pound laptop and a 5-pound pair of boots to your bag without going over the weight limit?
Yes, the total being added is 4 pounds, which is a solution of the inequality
No, the total being added is 14 pounds, which is not a solution to the inequality
Yes, the added weight needs to be less than 38 pounds, and 9 plus 5 is less than 38.
No, the added weight needs to be at least 38 pounds, and 9 plus 5 is less than 38.
Answer:
Let the additional weight that can be added be = x
Current weight of the bag = 38 pounds
Total weight can be = 50 pounds
The equation becomes:
38+x < or equal 50
x < or equal 50-38=12
Hence, a weight of 12 pounds cab be added to the current wight.

Solve the equation 3(x-6)+8=5x-6
Answer:
x=-10
Step-by-step explanation:
3(x-6) +8=5x-6=
3x-18+8=5x-6=
3x-10=5x-6=
3x-5x=10-6=
-2x=4
x=-2
Answer:
x = -2
Step-by-step explanation:
3(x - 6) + 8 = 5x - 6
Distribute;
3x - 18 + 8 = 5x - 6
Collect like terms;
3x - 10 = 5x - 6
Subtract 5x from both sides;
-2x - 10 = -6
Add 10 to both sides;
-2x = 4
Divide both sides by -2
x = -2
According to the synthetic division below, which of the following statements
are true?
Check all that apply.
The question is not complete, so i have attached it.
Answer:
Options A, B & E are correct
Step-by-step explanation:
In the synthetic division attached, we see that:
: 2 , -2 & -12 are the coefficient of the dividend of the function 2x² - 2x - 12
: The divisor is 3
Thus;
x = 3 is a root of f(x) = 2x² - 2x - 12
Thus, (x - 3) is a factor of the dividend which is the function f(x) = 2x² - 2x - 12
- Now, from the attached image, the coefficients of the quotient are 2 , 4
- The quotient will be 1 degree less than the dividend since it was divided by the factor (x - 3)
The degree of the dividend will be 2 since it contains x²
Thus, the degree of the quotient will be 1
Therefore, the quotient in factor form is (2x + 4)
Looking at the given statements in the options;
- Option A is true, because we have established earlier that 3 is a root of f(x) = 2x² - 2x - 12
- Option B is true because we have established that (x - 3) is a factor of 2x² - 2x - 12
- Option C is not true because the factor is (x + 3) and not (x - 3)
-Option D is not true because the root is 3 and not -3
- Option E is true because we have established that quotient as a factor is: (2x + 4)
Thus, the correct options are A , B , E

5, 18, 6, 18, 13 find the interquartile range (SHOW WORK)
Answer:
12
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile.
Firstly find the median of the data.
The median is the middle value of the data arranged in ascending order. If there is no exact middle value then it is the average of the values either side of the middle.
5, 6, 13, 18, 18 ← data in ascending order
↑ middle value
median = 13
The upper quartile Q₃ is the middle of the data to the right of the median
13, 18, 18
↑ middle value
Q₃ = 18
The lower quartile Q₁ is the middle value of the data to the left of the median
5, 6, 13
↑ middle value
Q₁ = 6
Interquartile range = Q₃ = Q₁ = 18 - 6 = 12

OR
Answer:
1. It can clearly observed that all the ratios that are written in fractional form simplify to same fraction which means that all the ratios are equivalent.
2. None of them will taste different as the ratios are same.
Step-by-step explanation:
First of all we have to write the three ratios as fractions to see if the ratios are equivalent ratios or not.
We will see the water to cups ratio
The ratios in fractional form are:
[tex]=\frac{1}{3}\\=\frac{4}{12}\\=\frac{6}{18}[/tex]
Putting all the ratios together
[tex]\frac{1}{3} = \frac{4}{12} = \frac{6}{18}\\\frac{1}{3} = \frac{1}{3} = \frac{1}{3}[/tex]
1. It can clearly observed that all the ratios that are written in fractional form simplify to same fraction which means that all the ratios are equivalent. All the recipes will taste same.
2. None of them will taste different as the ratios are same.
When a baby was born, he weighed 5.2 pounds, After two weeks, he
weighs 7.8 pounds. What is the percent of increase in the baby's weight
from the time he was born to two weeks later? *
Answer:How much weight should newborns gain?
A healthy newborn is expected to lose 7% to 10% of the birth weight, but should regain that weight within the first 2 weeks or so after birth. During their first month, most newborns gain weight at a rate of about 1 ounce (30 grams) per day.

Step-by-step explanation:
The profit (in millions of dollars) for a producer of electric scooters can be modeled by P=-x^3+7x where x is the number of scooters produced (in millions). Currently the company produces 2 millions scooters and makes a profit of $6,000,000. What lesser number of scooters could the company produce and still yield the same profit?
Answer:
1 million scooters
Step-by-step explanation:
We are told that the profit (in millions of dollars) for a producer of electric scooters can be modeled by P = -x³ + 7x where x is the number of scooters produced (in millions).
We are told that currently the company produces 2 millions scooters and makes a profit of $6,000,000.
Thus, the profit equation is;
6 = -x³ + 7x
x³ - 7x + 6 = 0
We are given 2 as a root.
Let's try 1.
1³ - 7(1) + 6 = 0
0 = 0
So 1 is a root.
Thus, the lesser number of scooters the company could produce and still yield the same profit is 1 million scooters
