Answer:
if you divide anything by 1/2 you are basically multiplying by 2 so any number divided by 1/2 will just be ×2

I am attaching a pic of the work . When you divide fractions remember this cute saying “KCF” which stays for : Keep , Change , Flip

PLZZZZZZZZZZZZZZZZZZ HELP willam and debra are celebrating their anniversary by having a reception at a local reception hall. They have budgeted for their reception. If the reception hall charges a cleanup fee plus per person, find the greatest number of people that they may invite and still stay within their budget
Answers
Answer:
William and Debra pierce can invite 140 people for the 20th anniversary.
Step-by-step explanation:
Total budget = 4500 $
Charge of cleanup = 60$
Remaining money = 4500 - 60 = 4440 $
Charge per person = 30 $
Number of persons they can invite
So William and Debra pierce can invite 140 people for the 20th anniversary.

Step-by-step explanation:
1) Let width = x
One side of the rectangle is covered by river. So only, 3 sides to be covered.
length = 100 - ( x + x) = 100 - 2x
Area of rectangle = length *width
= (100 - 2x)*x

How do the expressions 9+m2−3 and 8(m+3)−2m compare when m = 8?
Drag a symbol into the box to correctly complete the statement.
Answers
The symbol that correctly completes the statement is <
Given the expression
9+m2−3 and 8(m+3)−2m
If m = 8
f(m) = 9+8^2−3
f(m) = 9 + 64 - 3
f(m) = 70
For g(m) = 8(m+3)−2m
g(m) = 8(8+3) - 2(8)
g(8) = 8(24) - 16
g(8) = 191
This shows that f(8) < g(8). Hence the symbol that correctly completes the statement is <

Eva is short on frosting! She works in a bakery and has 12 cakes to frost, but she is short 418 cups on the amount of frosting required. She decides that she will spread the frosting she has among the 12 cakes. She makes a sign for the cakes and names them by the value that represents the amount of frosting on each cake compared to the amount it should have. What does the sign say?
Answers
The frosting which will be short on each of Eva's 12 cakes shared equally on each will be [tex] \frac {11}{32}[/tex]
Number of cakes to frost = 12
Shortage on required frosting = [tex] 4 \frac{1}{8} [/tex]
Spreading the frost on each of the 12 cakes available :
Divide the shortage on required frost by the number of cakes
Shortage on required frosting ÷ Number of cakes to frost
[tex] \frac{33}{8} \div 12 = \frac{33}{8} \times \frac{1}{12} = \frac{(33\times1)}{96} = \frac {11}{32}[/tex]
Therefore, each frosted cake will be short of [tex]\frac{11}{32} \: cups [/tex]

Answers
Answer:
y = - 2x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (2, - 3) ← 2 ordered pairs from the table
m = [tex]\frac{-3-(-1)}{2-1}[/tex] = [tex]\frac{-3+1}{1}[/tex] = - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute any ordered pair from the table into the partial equation
Using (3, - 5 ) , then
- 5 = - 6 + c ⇒ c = - 5 + 6 = 1
y = - 2x + 1 ← equation of line
Answer:
Step-by-step explanation:
We will need to find the equation and put it in the form y = mx + b where m is the slope and b is the y intercept.
Step 1 - Calculate the slope via the slope formula:
[tex]\frac{(y2 - y1)}{(x2 - x1}[/tex]
We will use the first two x and y variables in the table, so simply plug the values in.
[tex]\frac{(-3) - (-1)}{2 - 1}\\[/tex]
= [tex]\frac{-2}{1} = -2[/tex]
This means the slope is 2 (y = -2x + b).
Step 2 - Plug the variables in:
To calculate the b, we can use one of the pairs of coordinates i.e. (1, -1) to calculate b by putting the variables into the above equation:
y = -2x + b
-1 = -2(1) + b
-1 = -2 + b
-1 + 2 = b
b = 1
This means the equation is:
y = -2x + 1
Hope this helps!

Mr. Jones wants to place a chimney on his roof. It is recommended that the chimney be set at a height of at least 30 feet. The height of the roof is described by the function f(x)=−4/3|x−10| + 40 where x is the distance along the width of the roof. Where should Leroy place the chimney if the house is 45 feet wide?
Answers
Absolute value of any number is always positive because it represent distance and distance will always positive.
To place chimney at least 30 feet , the distance along the width of the roof (x) will be x = 17.5 feet or x = 2.5 feet.
Since, The height of the roof is described by the function f(x)=−4/3|x−10| + 40
Since, minimum height is 30 feet.
So , substitute f(x)=30 in above expression.
30=−4/3|x−10| + 40
4/3|x−10| = 10
|x−10|=30/4
|x−10| = 7.5
Taking positive case,
x−10 = 7.5
x = 17.5 feet
Taking negative case,
x−10 = - 7.5
x = 10 - 7.5
x = 2.5 feet

Glven the system below:
f(x) = 2^x
g(x) = 2^x
Which value(s) of x make f(x) = g(x) a true statement? If necessary, you may choose more than one answer.
Answers
The correct answers are 1 and 2.
Given the functions, f(x) = 2x and g(x) = 2^x
Plug the given options to see which value of x makes f(x) = g(x):
For x = 0:
f(0) = 2(0) = 0
g(0) = 2^(0) = 1
Therefore, since f(0) ≠ g(0), then it is not a solution to the given system.
For x = 1:
f( 1 ) = 2( 1 ) = 2
g( 1 )= 2^( 1 ) = 2
Therefore, since f(1 ) = g( 1 ), then IT IS a solution to the given system.
For x = 2
f( 2 ) = 2( 2 ) = 4
g( 2 )= 2^( 2 ) = 4
Therefore, since f( 2 ) = g( 2 ), then IT IS a solution to the given system.
For x = 3:
f(3) = 2(3) = 6
g(3) = 2^(3) = 8
Therefore, since f(3) ≠ g(3), then it is not a solution to the given system.
For x = 4:
f(4) = 2(4) = 8
g(4) = 2^(4) = 16
Therefore, since f(4) ≠ g(4), then it is not a solution to the given system.
Thus, 1 and 2 are the solutions to the given system that makes f(x) = g(x).
