Answer:
2
Step-by-step explanation:
The recipe calls for 6 cups of shredded cheese and 4 tablespoons of milk. You need to find how much milk Nolan needs for 3 cups of shredded cheese. Write a proportion.
6 cups of shredded cheese
4 tablespoons of milk
=
3 cups of shredded cheese
? tablespoons of milk
Compare the numerators.
6cups of shredded cheese
4 tablespoons of milk
=
3cups of shredded cheese
? tablespoons of milk
To get from 6 to 3, divide by 2. Divide the numerator and denominator by 2 to find the amount of milk that Nolan needs.
6cups of shredded cheese÷2
4 tablespoons of milk÷2
=
3cups of shredded cheese
2tablespoons of milk
Nolan needs 2 tablespoons of milk for a smaller batch.
is a relation that is also a function.
{(1,6), (1,7), (7, 8), (8, 9)}
{(2,3), (3, 2), (2, 4), (4, 2)}
{(0, 1), (0, 2), (0, 3), (0,4)}
|{(1, 1), (3, 2), (6,3), (8,4)}
Answer:
The relation {(1, 1), (3, 2), (6,3), (8,4)} is also a function ⇒ D
Step-by-step explanation:
The relation formed from a set of ordered pairs could be a function if every x-coordinate has only one y-coordinate corresponding to it
Examples:
The relation {(1, 3), (-2, 5), (1, -2)} is not a function because x = 1 has two values of y 3 and -2The relation {(2, -3), (-2, 0), (1, 5)} is a function because x = 2 has only y = -3, x = -2 has only y = 0, and x = 1 has only y = 5Let us check all the relation to find which one is a function
∵ The relation is {(1, 6), (1, 7), (7, 8), (8, 9)}
∵ At x = 1, y = 6 and 7
→ x has two values of y
∴ The relation is not a function
∵ The relation is {(2, 3), (3, 2), (2, 4), (4, 2)}
∵ At x = 2, y = 3 and 4
→ x has two values of y
∴ The relation is not a function
∵ The relation is {(0, 1), (0, 2), (0, 3), (0,4)}
∵ At x = 0, y = 1, 2, 3, and 4
→ x has four values of y
∴ The relation is not a function
∵ The relation is {(1, 1), (3, 2), (6,3), (8,4)}
∵ At x = 1, y = 1
∵ At x = 3, y = 2
∵ At x = 6, y = 3
∵ At x = 8, y = 4
→ Every x has only one value of y
∴ The relation is a function
∴The relation {(1, 1), (3, 2), (6,3), (8,4)} is a function
Which of the following is equivalent to 5x-6y=20?
A y=5/6x
B y=5/6x-10/3
C y=6/5x+4
D y=-5/6x
Answer:
y = [tex]\frac{5}{6}[/tex]x - [tex]\frac{10}{3}[/tex]
Step-by-step explanation:
Given expression:
5x - 6y = 20
To solve this problem, we make y the subject of the expression:
Solution
5x - 6y = 20
Add -5x to both sides of the expression;
-5x + 5x - 6y = 20 + (-5x)
-6y = 20 - 5x
Now, multiply both sides by [tex]-\frac{1}{6}[/tex] ;
[tex]-\frac{1}{6}[/tex] x (-6y) = [tex]-\frac{1}{6}[/tex] (20 - 5x )
y = [tex]-\frac{20}{6}[/tex] + [tex]\frac{5}{6}[/tex]x
y = [tex]\frac{5}{6}[/tex]x - [tex]\frac{10}{3}[/tex]

Question 5 please. I need help with thus.
Answer:
TU = 63.84 in
Step-by-step explanation:
Since T lies on RU, then
RT + TU = RU, substitute values
9x - 2.64 + 11x - 4.36 = 117, that is
20x - 7 = 117 ( add 7 to both sides )
20x = 124 ( divide both sides by 20 )
x = 6.2
Thus
TU = 11x - 4.36 = 11(6.2) - 4.36 = 68.2 - 4.36 = 63.84 in

What's the difference between how we find the sale price of discounts and how we find the total price of tax, tips, and mark ups?
To find the actual discount, multiply the discount rate by the original amount 'x'. To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price.
During an investigation on speed, a ball rolls down a ramp a distance of 8 m in a time of 2 seconds. What is the average speed of the ball in m/s?
Answer:
4 m/s
Step-by-step explanation:
To find the average speed of the ball, divide the number of meters by the number of seconds:
8/2
= 4
So, the average speed of the ball is 4 m/s
A jetliner uses 3,600 gallons of fuel per hour while it is cruising, and there are 15,000 gallons of fuel in the jetliner's fuel tank when it begins to cruise. If y represents the amount of fuel, in thousands of gallons, remaining in the fuel tank after the jetliner cruises for x hours, determine the graph of the solution set for this situation and the equation modeled by the graph.
Answer:
y = 15 - 3.6x.
Step-by-step explanation:
The initial amount of fuel before cruising begins = 15,000 gallons.
The equation is y = 15 - 3.6x where y is in thousands of gallons and x = number of hours.

EASY 10 POINTS QUESTION 7 PLEASEEEEEEE
Answer:
x=9
Step-by-step explanation:
-2x+9=-4x+27
first you want to get the -4x on the other side of the equal sign you do that by -4- -4 which will cancel them out and you do -2 - -4 = 2x
now you have 2x+9=27 now you do 9-9 which will cancel them out and you do 27 - 9 = 18
Now you have 2x=18 then you want to divide 2 by 2x which will cancel out the 2 and you want to divide 2 by 18 which equals 9 so you answer is x=9
hope this helps
I do not know which formula to use
Carla bought a dress at a sale for 20% off the original price. The sale price of the dress was $68.90. Find the original price of the drees, in dollars.
Step by step explanation please.
Answer:
I think it's the second formula.
Step-by-step explanation:
Let x be the original price.
The discount rate is 20%
Sale Price is $68.90
Discount = 20% of x = 0.2x
Using the formula, Sale Price = Original Price - Discount,
Original Price - Discount is x-0.2x = 0.8x
$68.90 = 0.8x
From here on, just do the equation :) Hope this helps!
