Solve for v.
2(V-1)=8v+10
Answer:
what are the options?
Step-by-step explanation:
8 + 7x =8x+1
Answer choices: 9,-7, 7, -9
Answer:
Step 1: Simplify both sides of the equation.
7x+8=8x+1
Step 2: Subtract 8x from both sides.
7x+8−8x=8x+1−8x
−x+8=1
Step 3: Subtract 8 from both sides.
−x+8−8=1−8
−x=−7
Step 4: Divide both sides by -1

Answer:
h = 2.5
Step-by-step explanation:
This question deals with a translation applied to the parent function, f(x) = |x|.
The parent function of the absolute value equation is f(x) = |x|. The graph of f(x) = |x| is a V-shaped graph as shown in the graph, but the vertex of the V is at (0, 0).
When you substitute x - h for x, you translate the parent function h units horizontally. When you substitute y - k for y, you translate the parent function k units vertically.
Think of the parent function described above, f(x) = |x|.
Its vertex is at the origin, (0, 0).
Now look at the function in your graph. It is a horizontal and vertical translation of the parent function since the vertex is now at (2.5, 1.5).
The horizontal translation was from x = 0 to x = 2.5, so h is 2.5.
As mentioned above, when you substitute x - h for x, you translate the function h units horizontally. Since the horizontal translation is 2.5, h = 2.5.
Answer: h = 2.5
If RS = 17, ST = x + 6, and RT = 3x - 5, What is ST.
Answer:
ST = 20
Step-by-step explanation:
Line segment RS and segment ST must add up to line segment RT
Step 1: Define
RS = 17
ST = x + 6
RT = 3x - 5
Step 2: Set up equation
mRS + mST = mRT
17 + x + 6 = 3x - 5
Step 3: Solve for x
x + 23 = 3x - 5
23 = 2x - 5
28 = 2x
x = 14
Step 3: Find mST
ST = x + 6
ST = 14 + 6
ST = 20

21(2−x)+12x=44 what the answer
Step-by-step explanation:
21 (2-x)+12x=44
first,open the brackets
42-21x+12x=44
second, collect like terms
42-9x=44
-9x=44-42
-9x=2
third, dived both sides by -9

Evaluate f(x) = x2 for f(-8).
On evaluating the function at x = -8, we get -
f(-8) = 64.
We have a function -
f(x) = [tex]x^{2}[/tex]
We have to find the value of f(x) at x = -8.
Evaluate - f(x) = Sin( [tex]\frac{\pi }{x}[/tex] ) at x = 4.f(x) = Sin( [tex]\frac{\pi }{x}[/tex] )
f(4) = Sin( [tex]\frac{\pi }{4}[/tex] )
f(4) = [tex]\frac{1}{\sqrt{2} }[/tex]
According to the question, we have -
f(x) = [tex]x^{2}[/tex]
Now, evaluating the function at x = -8, we get -
f(- 8) = [tex](-8)^{2}[/tex] = -8 x -8 = 64
Hence, on evaluating the function at x = -8, we get -
f(-8) = 64.

Sherry claims that the expression 1/x will always be equivalent to a repeating decimal whenever x is an odd number greater than 1
Answer:
The correct options are :
b. 5
e. 25
Step-by-step explanation:
The question is incomplete. The missing part is :
'' Which of these values will prove Sherry's claim is false :
a. 3
b. 5
c. 7
d. 11
e. 25 ''
One way to prove that Sherry's claim is false is finding one odd number greater than 1 that when we replace it in the denominator of the expression [tex]\frac{1}{x}[/tex] the result isn't equivalent to a repeating decimal.
Let's analyze each option :
a. 33 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{3}[/tex] ≅ 0.3333 (repeating decimal)
The option a. 3 won't prove that Sherry's claim is false.
b. 55 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{5}=0.2[/tex]
The result isn't a repeating decimal.
The option b. 5 will prove that Sherry's claim is false.
c. 77 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{7}[/tex] ≅ 0.1428 (repeating decimal)
The option c. 7 won't prove that Sherry's claim is false.
d. 1111 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{11}[/tex] ≅ 0.0909 (repeating decimal)
The option d. 11 won't prove that Sherry's claim is false.
e. 2525 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{25}[/tex] ≅ 0.04
The result isn't a repeating decimal
The option e. 25 will prove that Sherry's claim is false.

The price for strawberries is currently $ 6.40 per pack. next week,strawberries will be on sale at a 20% discount. what is the total price you would pay for 2 1/2 packs of strawberries next week?
Answer:
answer is $5.12
Step-by-step explanation:
Using the formula two and replacing the given values:
Sale Price = Original Price - Amount Saved. So,
Sale Price = 6.40 - 1.28
Sale Price = $5.12 (answer)
This means, the cost of the item to you is $5.12.
You will pay $5.12 for an item with original price of $6.40 when discounted 20%. In other words, if you buy an item at $6.40 with 20% discounts, you pay $6.40 - 1.28 = $5.12
Suppose Have you received a amazon promo code of 1.28. If the price is $6.40 what was the amount saved in percent:
3) 1.28 is what percent off $6.40?
Using the formula two and replacing the given values:
Amount Saved = Original Price x Discount % /100. So,
1.28 = 6.40 x Discount % / 100
1.28 / 6.40 = Discount % /100
100 x 1.28 / 6.40 = Discount %
128 / 6.40 = Discount %, or
Discount % = 20 (answer)

What are the 2 steps to solve this equation, 2x + 4 = 10.
4-3x=2x-11
solve for x
Answer:
x=3
Step-by-step explanation:
So first thing you are going to want to do is move like terms to the same side.
4-3x=2x-11
4+11=2x+3x
Signs get switched when moved.
Then you combine the like terms.
4+11=2x+3x
15=5x
Do a quick little switch of sides (this doesn't effect anything in the equation, just makes it easier to look at)
5x=15
Then to get rid of the exponent on the variable (the 5 in front of the x) you divide out the exponent on BOTH SIDES
(Remember what you do to one side of the equation you have to do to the other)
5x=15
x=3

The formula P=c+m can be used to determine price P of an
item that costs c cents and a markup of m cents. The markup on a
can of juice is 25 cents. What is an equivalent version of this
Formula solved for c?
Answer:
c = P-25Step-by-step explanation:
Given the formula P = c+m which is used to determine price P of an item that costs c cents and a markup of m cents. To get the value of c, we will make c the subject of the formula;
P = c+m
subtract m from both sides
P-m = c+m-m
P-m = c
c = P-m
Given the price of mark up on a can of juice to be 25 cents, we will substitute m = 25 into the resulting expression as shown;
c = P-25
Hence the equivalent version of this formula solved for c is c = P-25
