please answer!! it’s 12:08 am and i’m trying to get these two questions done
Answers
Answer:
21 and 14
Step-by-step explanation:
The relationship between x and y is proportional thus the equation is
y = kx ← k is the constant of proportion
To find k use the ordered pair y = 84 when x = 28 , then
84 = 28k ( divide both sides by 28 )
k = 3
y = 3x ← equation of proportion
When x = 7 , then
y = 3 × 7 = 21 ← value required in top table
When y = 42 , then
42 = 3x ( divide both sides by 3 )
x = 14 ← value required in lower table

The Millers receive a dinner bill for $122.75. The sales tax rate is 8%. They want to leave an 18% tip on the total bill after tax. How much money will they pay for their dinner with tax and tip?
Answers
Answer: 156.43
Step-by-step explanation:
Millers receive a dinner bill for $122.75. The sales tax rate is 8%. They want to leave an 18% tip on the total bill after tax. Then he pay 156.43 on total bill.
What is Percentage?Percentage, a relative value indicating hundredth parts of any quantity.
Given that,
Millers receive a dinner bill for $122.75.
The sales tax rate is 8%.
8/100=0.08
8% of bill is 0.08×122.75=9.82
After adding tax to the bill we get 122.75+9.82
=132.57.
18% tip on the total bill after tax is added
18/100=0.18
0.18 of 132.57
0.18×132.57
=23.86
The total bill is 132.57+23.86
=156.43
Hence $156.43 will they pay for their dinner with tax and tip.

The Solution of system of equation is (2, 2).
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
3x - y = 4............(1)
x + 2y = 6..............(2)
Solving equation (1) and (2) we get
3(6- 2y) -y = 4
18 - 6y - y = 4
18 -7y = 4
14 = 7y
y = 2
and, x= 6-2(2)
x = 6- 4
x= 2
Hence, the solution is (2, 2)

Jill owns a cupcake shop. In her 2nd month of business, Jill sold 330 cupcakes. In the 6th month, she sold 918 cupcakes. The growth of the business can be modeled by a linear equation.
Answers
The linear expression which models Jill's business growth is y = 147x + 36
Sales made by Jill :
2nd month = 330 cupcakes 6th month = 918 cupcakesGeneral form of a linear model :
y = bx + c y = final or predicted amount b = slope or growth rate c = intercept x = number of monthsWe can calculate the amount sold per month :
(6th month sale - 2nd month sale) / Number of months b = (918 - 330) / (6 - 2) = 588 / 4 = 147Using the second month ;
330 = 147x + c
x = 2
330 = 147(2) + c
330 = 294 + c
c = 330 - 294
c = 36
Therefore, the linear model can be expressed thus ;

One restaurant uses 5 quarts of soup to make 20 equal servings. Another restaurant uses 7 quarts of soup to make 25 equal servings. Which restaurant has larger servings of soup? Write division expressions to represent the problem and then solve.
Answers
Answer:
2nd restaurant
Step-by-step explanation:
Provided first restaurant uses 5 quarts of soup, and that total of 5 quarts of soup is equally divided in 20 bowls.
So each bowl has = [tex]\frac{Total\ quantity\ of\ soup}{total\ number\ of\ bowls} = \frac{5}{20} = 0.25\ quarts\ in\ each\ bowl[/tex]
On the other hand the second restaurant uses 7 quarts of soup for 25 bowls.
Quantity in each bowl = [tex]\frac{7\ quarts}{25\ bowls} = 0.28\ quarts[/tex]
Since the quantity of soup is more in each bowl of second case that is 0.28 quarts, it serves more soup.
Write the equation of a function whose parent function, f(x)= x + 6, is shifted 4 units to the right. Og%) = x - 10 O g(x)=-4 Og%) = x + 2 Ogl/)=+ 10
Answers
Given:
The parent function is
[tex]f(x)=x+6[/tex]
To find:
The equation of a function whose parent function, f(x)= x + 6, is shifted 4 units to the right.
Solution:
If parent function f(x) is shifted a units to the right to get the function g(x), then
[tex]g(x)=f(x-a)[/tex]
Here, a=4 units.
[tex]g(x)=f(x-4)[/tex]
[tex]g(x)=(x-4)+6[/tex] [tex][\because f(x)=x+6][/tex]
[tex]g(x)=x+2[/tex]
Therefore, the required function is [tex]g(x)=x+2[/tex] and option C is correct.
Identify the segment bisector of MN Then find MN.
????????? Helppp pleaseee
Answers
Given:
The figure.
To find:
The segment bisector of MN and value of MN.
Solution:
From the given figure it is clear that ray RP,i.e., [tex]\overrightarrow {RP}[/tex] is the segment bisector of MN because it divides segment MN in two equal parts.
Now,
[tex]3\dfrac{5}{6}=\dfrac{3\times 6+5}{6}[/tex]
[tex]3\dfrac{5}{6}=\dfrac{23}{6}[/tex]
Since, [tex]\overrightarrow {RP}[/tex] is the segment bisector of MN, therefore,
[tex]MN=2\times \dfrac{23}{6}[/tex]
[tex]MN=\dfrac{23}{3}[/tex]
[tex]MN=7\dfrac{2}{3}[/tex]
Therefore, the length of MN is [tex]7\dfrac{2}{3}[/tex].

Answers
Answer:
x = 6, y =-2
Step-by-step explanation:
5x+2y = 26
3x+2y = 14
Subtract the two equations to eliminate y
5x+2y = 26
-3x-2y = -14
---------------------
2x = 12
Divide by 2
2x/2 = 12/2
x = 6
Now find y
3x+2y = 14
3*6+2y = 14
18+2y = 14
Subtract 18 from each side
18+2y-18 =14-18
2y = -4
Divide by 2
2y/2 = -4/2
y = -2
Answer:
x=6
y=-2
Step-by-step explanation:
5x+2y=26
3x+2y=14
subtract
2x=12
x=12/2=6
3(6)+2y=14
2y=14-18=-4
y=-4/2=-2
