find the slope of a line through points (5,-8) and (-2,0)
Answer:
The slope of line through the points (5,-8) and (-2,0) is [tex]-\frac{8}{7}[/tex]
Step-by-step explanation:
Given points are:
(5,-8) and (-2,0)
Slope is the steepness of a straight line.
Slope of the line = m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will find the slope of the line through points (5,-8) and (-2,0) by putting values in the formula of slope
Here,
[tex]x_1= 5, y_1=-8\\x_2=-2, y_2=0[/tex]
Slope of the line = [tex]\frac{0-(-8)}{-2-5}[/tex]
Slope of the line = [tex]\frac{8}{-7}=-\frac{8}{7}[/tex]
Hence,
The slope of line through the points (5,-8) and (-2,0) is [tex]-\frac{8}{7}[/tex]

Answer:
n = 1x = 65Step-by-step explanation:
Given
18n + 12 = 27n + 3 5(x + 7) = 6(x - 5)Solving for variables
1
18n + 12 = 27n + 3 18n - 27n = 3 - 12-9n = -9n = -9/-9n = 12
5(x + 7) = 6(x - 5)5x + 35 = 6x - 305x - 6x = -30 - 35-x = -65x = 65Answer:
18n + 12 = 27n + 3
12-3=27n-18n
9=9n
n=9/9=1
5(x + 7) = 6(x - 5)

46/21 as a decimal rounded to the nearest tenth
Answer:
2.2
Step-by-step explanation:
46/21 rounded to nearest tenth place is zero.
What is rounding of nos. ?Rounding nos. to nearest places have an advantage that is we could remember the number easily.
For example - 16534 rounded to ten thousand's place is 20000 which is more easier for us to remember and also the number rounded to a certain place retains it's value to about that place.
According to the given question we have to convert the fraction 46/21 as a decimal rounded to the nearest tenth.
We know,
46/21 is
= 2.2 approximately .
Now, if we round 2.2 to the nearest tenth, 2.2 can be written as 02.2.
We observe that it's tenth digit is 0 so when we round it to the nearest tenth place it will be 0.

A necklace that regularly sells for $88.40 is on sale for 25% off. Find the
sale price of the necklace
Answer:
66.3
Step-by-step explanation:
First, you need to find the 25% of $88.40.
88.40×25% (or) 25/100 = □/88.40
Solve that and you should get 22.10.
22.10 is 25% of $88.40
Finally, subtract your percent from original price and boom!
88.40 - 22.10 = $66.30
An electrician earns 100 dollars for a project installing light fixtures. She must pay for the light fixtures herself and they cost 2 dollars and 50 cents each at the hardware store.
Create an equation to represent her profit from the project. Let x represent the number of light fixtures and y represent her total profit (the amount of money she has left over after paying for the light fixtures).
Answer:
y = 100 - 2.5 x is the equation that represents her total profit from
the project
Step-by-step explanation:
The given is:
1. An electrician earns 100 dollars for a project installing light fixtures
2. She must pay for the light fixtures herself and they cost 2 dollars
and 50 cents each
3. x represent the number of light fixtures and y represent her
total profit
Her profit is the amount of money she has left over after paying for

Which table contains points from the inverse of the graphed function?
Step-by-step explanation:
The table that is highlighted shows the points of the graphed function.
However we wish to find the inverse. We need to swap the values of x and y for each of the points to get the inverse.
Hence the answer is Option C.
Inverse operations add up, multiply, divided?
Answer:
Addition and subtraction are inverse operations. Start with 7, then add 3 we get 10, now subtract 3 and we get back to 7.
Another Example: Multiplication and division are inverse operations. Start with 6, multiply by 2 we get 12, now divide by 2 and we get back to 6.

Henry is planning to create two rectangular gardens.
Part A
Henry has 96 feet of fencing to enclose the first rectangular garden. The garden will be x feet wide.
Which function, f(x), can Henry use to determine the area, in square feet, of the first garden?
a f(x) = 48x
O f(x) = 48 - X
f(x) = 48 – x2
d -
f(x) = 48x-x²
Answer:I’m taking the same quiz rn and am confused
Step-by-step explanation:
The function to represent the area of the garden is f(x) = 48x-x²
What is a function?A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and range.
Given that, Henry has 96 feet of fencing to enclose the first rectangular garden. The garden will be x feet wide.
Perimeter = 96 feet
Therefore,
2(l+x) = 96
l+x = 48
l = 48-x
Area = lXw
= x(48-x)
= 48x-x²
Hence, The function to represent the area of the garden is f(x) = 48x-x²

15. What is -130 = -9k - 4
Answer: 14
Work: First, we must get rid of the four from the side it's currently on. So, we are going to add it on both sides. After adding four on both sides, I'll cancel on the side it was on, and the new equation is -126 = -9k. Now, we are going to divide -9 on both sides and yet again, I'll cancel on the side it was on. The answer is k = 14. It's a positive 14 because we divided a negative by a negative, and after doing so, the new number is a positive.

Step-by-step explanation:
And your answer is 100% wrong, the correct answer is 30x - 8
now I won't let you down so here it is:
a useful mathematical term(s) is PEMDAS ( Parenthesis, exponent, Multiplication, division, addition, subtraction)
first: the P:
3x(6+4)-2 * 4 >> 3x (10) -2 *4
second: since there are no Exponents you skip to M:
3x(10) - 2 * 4 >> 30x - 8
and done because 30x and 8 are not like terms so this is as far as you go!
Bonus: like terms ex: 8 + 8 or 30x + 30x are like terms so you cant do 30x - 8!
Hope it helps!
