Answer:
x=√y+4 or x=−√y+4
Step-by-step explanation:
Step 1: Add 4 to both sides.
x2−4+4=y+4
x2=y+4
Step 2: Take square root.
x=√y+4 or x=−√y+4
Set up a proportion to solve: 24 is 25% of what number?
Answer:
96
Step-by-step explanation:
25% can be written as 0.25
so:
24= .25*x
Divide both sides by 0.25
24 - .25x
.25 - .25
x=96

Zero
Infinitely many
One
Answer:
x= 0 has one solution
Step-by-step explanation:
Here, we want to get the number of solution
Looking at the relation, we can see that what we have is a linear relation
mathematically, a linear relation has a single solution
Thus, x = 0 has one solution
What is the contra post I’ve of this conditional statement
Answer:
Option (2)
Step-by-step explanation:
Statement p → If an animal is an adult insect
Statement q → It has six legs
Contrapositive statement means: -q → -p
"If not q then not p"
Therefore, costrapositive statement of the given conditional statement will be,
If the animal does not have six legs, then it is not an adult insect.
Option (2) will be the answer.

Kara is the manager of a video game store. She is in charge of buying the video games for the store to sell. She buys video games from a wholesaler that sells them for $10
each. The wholesaler also charges a fee of $160 for each bulk purchase. Kara then sells the video games for $14 each.
Write an equation to represent the cost to buy videos from the wholesaler. Let x represent the number of videos bought. Let y represent the total cost in dollars.
Answer: y = 10x + 160
Step-by-step explanation:
The cost follows the linear equation format of:
y = mx + c
Where:
y = dependent variable or the total cost
m is the cost per each additional unit of x
x is the number of video games
c is the constant cost or rather the fee per bulk purchase
Formula is therefore:
y = 10x + 160
Using the formula. Assuming Kara buys 100 video games, the cost would be:
y = 10 * 100 + 160
y = $1,160

I NEED HELP! I've failed this test twice and need to get it right. HELP PLEASE!
Answer:
180
Step-by-step explanation:
C + D = 180 degrees since they are a linear pair
D = 127 degrees, so
C + 127 = 180
to get the C, you need to subtract 180 degrees bt 127 degrees
180 - 127 = C

at the grocery store, 8 oranges cost $4. What is the cost for 9 oranges
Answer:
$4.50
Step-by-step explanation:
First you find the cost of each orange
4 divided by 8 = 0.5
so if each orange is $0.5 you can multiply it by 9 which is the amount of oranges there are
9 * 0.5 = $4.50

what is the slope of the line passes through the points (-3, -3) and (-5, -2) in simplest form help me
Answer:
Slope, [tex]m=\dfrac{-1}{2}[/tex]
Step-by-step explanation:
We need to find the slope of the line passes through the points (-3, -3) and (-5, -2).
The formula for the slope of a line is given by :
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Put x₁ = -3, y₁ = -3, x₂ =-5 and y₂ = -2
So,
[tex]m=\dfrac{-2-(-3)}{-5-(-3)}\\\\m=\dfrac{-1}{2}[/tex]
So, the slope of the line is [tex]\dfrac{-1}{2}[/tex].
Solve by completing the square x^2-10x-24=0
Answer:
x = -2 and x =12
Step-by-step explanation:
Explanation:-
Given equation x² - 10 x - 24=0
x² - 12 x +2x - 24 =0
⇒ x (x-12) +2( x -12) =0
⇒ x+2 =0 and x-12 =0
x = -2 and x =12

The Bridal Shop bought a dress from a supplier for $105 wholesale and applied a 65% markup to the price.
If a 7.5% sales tax were added after a 20% discount was used, what would be the total cost to purchase the dress?
A
$146.20
B
$149.00
C
$158.48
D
$160.17
Answer:
B $149.00
Step-by-step explanation:
105 * 1.65 = 173.25 (100%+ 65%) Price with the markup
173.25 *0.80 138.60 (Price after 20% discount .The price will be the 80%)
138.60 * 1.075 = 148.995 (price with 7.5 sales tax.)
Select the fraction that is equivalent to one half.
HOW DO I DO THIS PLZ HELP
Answer:
1/2 one half
Step-by-step explanation:
Answer:
Multiply both the numerator and the denominator by the same whole number.
For example;
If you multiply 1/2 by 2/2, this will equal 2/4. You can simplify 2/4 to 1/2.
So to find 1/2 to be equivalent to another fraction, multiply both the numerator and the denominator by the same number to find a fraction that equals 1/2.
- 10x -12 = -12x + 4
Solve for x pls
Answer:
x=8
Step-by-step explanation:
- 10x -12 = -12x + 4
-10x+12x=4+12
2x=16
x=8
x = 8
Explanation:- 10x -12 = -12x + 4Add 12x to both sides−10x − 12 + 12x = −12x + 4 + 12x
2x − 12 = 4
Add 12 to both sides2x − 12 + 12 = 4 + 12
2x = 16
Divide both sides by 22x / 2 = 16 / 2
x = 8- PNW
