Solve the following equation for "y": 3x-4y=20
Answer:
Step-by-step explanation:
20=3x-4y, add 4y to each side
4y+20=3x, subtract 20 from each side
4y=3x-20, divide each side by 4
y=(3x-20)/4 or if you prefer
y=0.75x-5
What is the value of the expression f(–3)?
-15
3
-3
15
Answer:
Option A, -15
Step-by-step explanation:
Step 1: Look at the function that needs to be outputted when x = -3
Since x = -3, that means it falls into the first category of x ≤ -3
Step 2: Carry out the instructions
The function for the first category is [tex]-x^{2} + 2x[/tex]
[tex]f(-3) =-(-3)^{2}+2(-3)[/tex]
[tex]f(-3) = -(9) - 6[/tex]
[tex]f(-3) = -15[/tex]
Answer: Option A, -15

What is the median of data set 32 25 25 32 32 10 -10 25
Answer:
25
Step-by-step explanation:
middle most common
Answer:
Median is 25
Step-by-step explanation:
Step 1: Organize the data from lowest to highest
-10 10 25 25 25 32 32 32
Step 2: Find the middle number
The two middle numbers would be 25 and 25, so we would take their average which is 25 obviously.
Therefore, the median of the data set is 25

Rotate (-7,5) 90 degrees clockwise about the origin and then translate the new point left 6
Answer:
[tex]P" = (-1,7)[/tex]
Step-by-step explanation:
Given
[tex]Point - (-7,5)[/tex]
90 degrees clockwise rotation
6 points left translation
Required
The new point
Apply the first transformation
90 degrees clockwise transformation
When a point P (x,y) is rotated in the clockwise direction by 90 degrees, the new point is: P' (y, -x)
So:
[tex]P = (-7,5)[/tex] becomes
[tex]P' = (5,7)[/tex]
Apply the second transformation
6 points left translation
To do this, we simply subtract 6 from the x coordinate
[tex]P' = (5,7)[/tex] becomes
[tex]P" = (5-6,7)[/tex]
[tex]P" = (-1,7)[/tex]

34. CONSTRUCTION A construction worker is working on the roof of a
building. A drop of paint falls from a rafter that is 225 feet above the
ground. After how many seconds does the paint hit the ground?
Answer:
t = 6.77 s
Step-by-step explanation:
Given that,
A drop of paint falls from a rafter that is 225 feet above the ground.
We need to find the time when the paint hit the ground. Let the time be t.
Using the second equation of kinematics i.e.
[tex]s=ut+\dfrac{1}{2}at^2[/tex]
Where
u = 0 (initial velocity is 0 as it was at rest)
a = g
So,
[tex]225=\dfrac{1}{2}\times 9.8t^2\\\\t=\sqrt{\dfrac{2\times 225}{9.8}} \\\\t=6.77\ s[/tex]
So, it will hit the ground at 6.77 s.
How do you check your answer or plug it in after solving |2x + 1| = 9 ???
Step-by-step explanation:
2x + 1 = 9
2x = 9 - 1
2x = 8
x = 8 ÷ 2
x = 4
----------------------------------FOLLOW MEPLEASE
Answer:
Step-by-step explanation:
To solve:
|2x+1|=9
|2x+1|=-9
2x=8
x=4
2x=-10
x=-5
2x+1=9
2(4)+1=9
9=9, so its true.
2x+1=-9
2(-5)+1=-9
-9=-9, so it’s true too

Chloe scored 24 points over the first 12 games of the basketball season. She scored 112 points over the last 16 games of the season. How many more points per game did Chloe score in the last 16 games of the season?
Answer:
5 points
Step-by-step explanation:
First, find how many points per game she scored over the first 12 games:
24/12
= 2 points per game
Now, find how many she scored in the last 16 games:
112/16
= 7 points per game
Find the difference:
7 - 2
= 5
So, she scored 5 more points per game in the last 16 games
Answer:
first 12 games- 24/12= 2ppg
Last 16 games- 112/16= 7ppg
7-2= 5 points per game more

Azim wants to buy a tablet computer that is priced 180.50 if the sales tax rate on the computer is 8% how many dollars and cents will Azim spend on the sales tax only
Answer: 98.1%
Explanation:
A 10% sale means that the post-sale price of the item is now 90%, or 0.9 of the original cost of the item. We then apply 9% sales tax by multiplying the 0.9 by 109%, or 1.09. 0.9 * 1.09 = .981, so the total cost of the item is 98.1% of the original pre-sale sticker price.
For percentage problems that do not deal with a specific starting number, it is always helpful to plug in 100 for the starting number. Here, we would then have a post-sale price of 90 dollars, and if we calculate the sales tax for the 90-dollar item it would be 90 * 0.09 = $8.10. THis gives us a total cost of 90 + 8.10 = $98.10, or 98.1% of the original 100-dollar price.

Easy brainliest for correct answer 100%
Answer:
B) A/l
Step-by-step explanation:
Isolate the variable, w. Note the equal sign, what you do to one side, you do to the other.
Divide l from both sides of the equation:
A = l * w
(A)/l = (l)/l * w
w = A/l
B) A/l is your answer.
