Step-by-step explanation:
Let's solve (4y - 3)^2 = 72 for y. To do this, take the square root of both sides. This yields:
4y - 3 = ±√72 = ±√(36·2) = ±6√2
Then 4y = 3 ±6√2, or
3 ± 6√2
y = ----------------

Elise wants to divide a sum of money between Hannah and Adil in the ratio 2 : 3 . Elise says: Hannah will get 2 3 of the money. To explain why Elise is not correct, find the fraction of the money that Hannah will get.
Answer:
2 / 5
Step-by-step explanation:
Given that :
Ratio of money division by Elsie between Hannah and Adil = 2 : 3
Hannah = 2 ; Adil = 3
Elsie says Hannah gets 2 /3 which is incorrect :
The correct fraction each gets is as follows
Fraction of money Given to each :
Total = (2 + 3) = 5
Hannah = 2 / total = 2 /5
Adil = 3 /total = 3 /5
Hence, the correct fraction Hannah gets is 2 /5
A store advertises a % markdown on a dishwasher with a selling price of $. Find the sale price. This is the greatest possible markdown that the store can discount the dishwasher without losing money. What does this tell you about the cost?
Complete question :
A store advertises a 20% markdown on a dishwasher with a selling price of $952. Find the sale price. This is the greatest possible markdown that the store can discount the dishwasher without losing money. What does this tell you about the cost?
Answer:
$761.60
Step-by-step explanation:
Given that :
Sales price = $952
Markdown % = 20%
Sales price = (100 - 20)% * $952
Sales price = 80% * $952
Sales price = $761.60
If 20% is the greatest possible markdown the store can give without losing money, then the price at which the store purchased the dishwasher is $761.60
Which is the best approximation for the value of 1022
Answer:
We know that √100= 10, so √102 is approximately 10

What is the slope of the line that passes through the points (5, -10) and(−3,−10)?
Answer:
the slope would be 0
Step-by-step explanation:
to find the slope subtract the two y's and the two x's, so:
first the y's: -10--10= -10+10=0
next the x's: -3-5=-8
then, divide them:
0/-8=0
so the slope is 0.

Three restaurants sell turkey sandwiches in a small town: Delicious Deli, Garden Fresh, and Uptown Eatery.
Delicious Deli sells 5 turkey sandwiches for $20.00.
Garden Fresh sells 2 turkey sandwiches for $8.50.
Uptown Eatery sells 3 turkey sandwiches for $13.50.
The graph shows Delicious Deli’s turkey sandwich sales, where x represents the number of turkey sandwiches sold, and y represents the total cost.
Answer:
$4 per Turkey
Step-by-step explanation:
Look on the graph and follow every number to the cost:
2 Turkeys: $8
4 Turkeys: $16
5 Turkeys: $20
Notice how there is a Pattern:
8, 16, and 20 are all multiples of 4
4 x 2 = 8
4 x 4 = 16
4 x 5 = 20
So, the constant of proportionality for the coast per sandwich and Delicious Deli is $4

David and Jillian are playing a boardgame together Jillian wants to trade her wool cards for David ore cards the double number line shows that David will trade three ore cards to Jillian for six wool cards based on the ratio shown in the double number line how many wool does Jillian need to trade for ore cards?
Answer:
Step-by-step explanation:
Given that:
Jillian is willing to trade her wool cards for David ore cards
The double number line indicates that:
David will trade three ore cards to Jillian for six wool cards;
Based on the ratio, we have:
[tex]= \dfrac{6}{3}[/tex]
= 2
Thus, the number of wool Jillian would need to trade for 1 ore card will be
= 1 × 2
= 2
For 2 ore card
= 2 × 2
= 4
For 3 ore card
= 3 × 2
= 6
The number of wool Jillian would need to trade for 4 ore card will be
= 4 × 2
= 8

If I have two points on a graph, let's say (4,5) and (8,10) what is the slope between the points?
Answer:
[tex]\displaystyle m=\frac{5}{4}[/tex]
Step-by-step explanation:
The slope between any two points is given by the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁, y₁) and (x₂, y₂) are our two points.
So, let’s let (4, 5) be (x₁, y₁) and let (8, 10) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{10-5}{8-4}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{5}{4}[/tex]
Therefore, the slope between the two points is 5/4 or 1.25.

The ratio 2 to 5 can be written as 2 : 5 or 2/5 or 2/(2 + 5) = 2/7 and
5/(2 + 5) = 5/7.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
A ratio a : b can be written as a/b. It can also be written as a/(a + b) and
b/(a + b).
So, the ratio 2 to 5 can be written as 2 : 5 or 2/5 or 2/(2 + 5) = 2/7 and
5/(2 + 5) = 5/7.

Which number has an absolute value that is equal to the absolute value of 32?
Answer:
-32
Step-by-step explanation:
The absolute value of a number is its distance from 0. Since distance is always positive the absolute value is the same number but positive. So the absolute value of -32 and 32 would both be 32 because they have the same distance from 0.

Identify the slope-intercept form and the graph of the line described by the equation 2x−y=0.
Answer: y=2x
Step-by-step explanation:
Let's solve for y.
Step 1: Add -2x to both sides.
2x−y+−2x=0+−2x
−y=−2x
Step 2: Divide both sides by -1.
-y/-1 = -2x.-1
y=2x
Therefore, the y=mx+b form of this question would be y=2x
Answer:
y = 2x
Step-by-step explanation:
In order to get from standard form to slope-intercept form (y = mx + b), we have to find what we are looking for. Since we want to get slope-intercept form, we want to find y. To find y, we isolate it.
2x - y = 0
Subtract 2x from both sides...
(2x - 2x) - y = (0 - 2x)
Now we have - y = -2x + 0.
But wait, we can't have a negative y... so we simply divide by -1.
(-y/-1) = (-2x/-1) + (0/-1).
Since 0 divided by any number is just zero, we can drop it. Now that y is positive, we have our answer!
