Answer:
e = 6
Step-by-step explanation:
Step 1: Write equation
-2(8 - e) = 2 - e
Step 2: Solve for e
Distribute -2: -16 + 2e = 2 - eAdd e to both sides: -16 + 3e = 2Add 16 to both sides: 3e = 18Divide both sides by 3: e = 6Step 3: Check
Plug in e to verify it's a solution.
-2(8 - 6) = 2 - 6
-2(2) = -4
-4 = -4
What is the equation of the line in point-slope form?
O y +4 = {(x+4)
O y-4 = 4(x + 4)
Oy-0 = 2(x-4)
Oy -4 = 2(x-0)
Answer: y + 4 = 1/2 (x + 4)
something x (-2) = 70
Answer:
The answer is x = -35

Line AB is parallel to line CD. What is the measure of angle CFE?
A 45°
B. 55°
C. 125°
D. 180°
Answer: c
Step-by-step explanation:
A full circle is 360 degrees so half way would be 180 and since theyre parallel you know that you can use the 55 degrees up top to use in ur equation to find cfe
180-55=125
Can't be 45 because the angle on the other side is smaller than cfe and its 55 degrees and cfe has to be wider than 90 degrees because a right angle is 90 degrees and this angle noticeable goes past 90
Can't be 180 because the whole thing equals 180
Which expression is equivalent to 2(a+3) when a=3?
O 2(3)
05(3)
O 2(3)+3
O 2(3)+6
Answer:
The answer is 2(3)+6
Step-by-step explanation:
The perenthesis means multiplication so you would first do 2 times three which is 6 and then 6+6=12 and the first expresion is 2(a+3) a=3 to solve that you would do whats in the perenthesis 3+3 which equals 6 and then the 6 in the perenthesis means mulitplication. so then you would do 2 times 6 and get 12. so the 3rd one is the answer.

Step-by-step explanation:
) Suppose you are installing a wood floor in a square room. The cost to install the floor is $9 per square foot. The area of the room is given by the function A(x) = x 2 and the cost per square foot is given by the function C(A) = 9A. Which function can be used to find the total cost to install the wood floor? A) A(C(x)) B) C(A(x)) C) x(A(C)) D) x(C(A))
Answer:
The correct option is;
B) C(A(x))
Step-by-step explanation:
The given information are;
The cost to install the floor per square foot = $9
The area of the room is given by the function A(x) = x²
The function for the cost per square foot = C(A) = 9·A
We note that the total cost to install the wood floor = (The cost to install the floor per square foot) × (The area of the room)
∴ The total cost to install the wood floor = $9 × x²
Given that A(x) = x², we have;
The total cost to install the wood floor = $9 × A(x)
Also, given that C(A) = 9·A, we have;
C(A(x)) = 9·A(x)
Therefore;
The total cost to install the wood floor in dollar amount can be given by the function, C(A(x)) = 9·A(x)

Alicia bought two slices of pizza and a bottle of juice for $4.95. The juice was $1.65. How much is one slice of pizza?
Subtract the price of the juice from the total then divide the remaining amount by 2:
4.95 - 1.65 = 3.30
3.30 /2 = 1.65 per slice.

A kindergarten teacher bought $21 worth of stickers and cardstock for his class. The stickers cost $1.50 a sheet and the cardstock cost $3.50 per pack. The equation 1.5s+3.5c=21 represents the relationship between sheets of stickers, s, packs of cardstocks, c, and the dollar amount a kindergarten teacher spent on these supplies.
1. Explain how we can tell that this graph represents the give equation.
2. What do the vertical and horizontal intercepts, (0,6) and (14,0), mean in this situation?
Answer:
Step-by-step explanation:
Teacher bought $21 worth of stickers and cardstock for his class.
Cost of stickers = $1.50 per sheet
Cost of 's' sheets = $1.5s
Cost of cardstock = $3.50 per pack
Cost of 'c' packs = $3.5c
Equation representing the relationship between sheet of stickers and packs of cardstocks will be,
1.5s + 3.5c = 21
3.5c = -1.5s + 21
1). [tex]c=-\frac{3}{7}x+6[/tex]
y-intercept of the line → (0, 6)
x-intercept of the line → (14, 0)
Therefore, equation of the line represents the line on the graph.
2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.
Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.

Every number has a reciprocal except for 0. There is nothing you can multiply by 0 to create a product of 1, so it has no reciprocal.
Answer:
1/5.
Step-by-step explanation:
When referring to a reciprocal, it basically means taking the numerator and the denominator and flipping them.
For example, take 4/5. The reciprocal of 4/5 would be 5/4.
Now, take 5. As a fraction, it would look like 5/1. If you were to flip it, it would be 1/5.
Therefore, the reciprocal of 5 is 1/5.

im not sure if this is right but i know that perpendicular means opposite so basically just swtich the slope and if its positive make it negative, vice versa
Two-thirds of the T-shirts in a T-shirt shop are blue. Three-fifths of those T-shirts are on sale. One-half of the blue T-shirts that are on sale are size medium. What fraction of the shop's T-shirts are blue T-shirts that are on sale and are size medium? Explain.
Let, total number of T-shirts are x.
Number of blue T-shirts = (2/3)x = 2x/3 .
Number of blue shirts on sale = (3/5)(2x/3) = 2x/5 .
Number of medium sized blue shirts on sale = (1/5)(2x/5) = 2x/25 .
Fraction of the shop's T-shirts are blue T-shirts that are on sale and are size medium = [tex]\dfrac{2x/25}{x}[/tex]= 2/25 . ( Number of medium sized blue shirts on sale divided by total number of T-shirts )
Hence, this is the required solution.
