Find the error for the proposed solution. Then correct the proposed solution.
2x + 18 = 16
2x = 34
2x 34
2 2
X = 17
Answer:
The error is in the second line.
x = -1
Step-by-step explanation:
When solving for "x", you are trying to isolate it, or move everything else to the other side. You may have learned that "what you do to one side, you do to the other" .
2x + 18 = 16
2x = 34 18 was added to the right side, but not to the other.
If you add 18 on both sides, then the equation would be:
2x + 36 = 34 "x" is not being isolated.
Instead, you should subtract 18 from 16.
Correct solutions steps:
2x + 18 = 16
2x + 18 - 18 = 16 - 18 Subtract 18 from both sides to cancel out 18
2x = -2
2x/2 = -2/2 Divide both sides by 2
x = -1 Final answer

Lola measures the heights and arm spans of the girls on her basketball team.
She plots the data and makes a scatterplot comparing heights and arm
spans, in inches. Lola finds that the trend line that best fits her results has the
equation y = x + 2. If a girl on her team is 65 inches tall, what should Lola
expect her arm span to be?

which line is parallel
Answer:
3x - y = -7
Step-by-step explanation:
put into slope-intercept form the equation becomes y = 3x + 7
parallel lines have the same slope, in this case the slope is 3
If f(x) =- 2x + 5, find f(4x)
Answer:
[tex]f(4x)=-8x+5[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)=-2x+5[/tex]
And we want to find:
[tex]f(4x)[/tex]
So, by substitution, we acquire:
[tex]f(4x)=-2(4x)+5[/tex]
Multiply. So, our answer is:
[tex]f(4x)=-8x+5[/tex]

Answer:
what you just answered
Step-by-step explanation:
2(5) + 3 = 13 so (5,1) is not
Answer:
D is the correct answer.
Step-by-step explanation:
1 times 2 is 2 plus 3 is 5, so its not A
2 times 2 is 4 plus 3 is 7 so its not B
and 3 times 2 is 6 plus 3 is 9 so it cant be C either
Therefore its D.

Find the area of the shaded regions below. Give your answer as a completely simplified exact value in terms of pi
Answer:
18π cm²
Step-by-step explanation:
The area of the shaded region = Area of Sector
Radius, r =
The value of θ = 80°
Recall :
Area of Sector :
A = θ / 360 * πr²
A = (80 / 360) * π * 9²
A = 0.222222 * π * 81
A = 18π cm²
Can anyone help this is due today
I’m having trouble understanding this, if anyone could help me understand it I’d greatly appreciate it.
Answer:
x = angle left of (4x+5) [ᴄᴏʀʀᴇsᴘᴏɴᴅɪɴɢ ᴀɴɢʟᴇs]
So, x + (4x+5) =180° [sᴜᴘᴘʟᴇᴍᴇɴᴛᴀʀʏ ᴀɴɢʟᴇs]
[tex](4x + 5 )+ x = 180 \\ 4x + 5 + x = 180 \\ 5x + 5 = 180 \\ 5x = 180 - 5 \\ 5x = 175 \\ x = \frac{175}{5} \\ x = 35[/tex]

an article bought a television for 2500 dollars and sold for 2325dollars find a.loss b.loss%
Answer:
Loss= $175
Loss %= 7%
Step-by-step explanation:
First of all, you find the difference between 2500 and 2325 which is 175, as his has decreased, it is a loss of $175
To find the percentage you do the difference over the original amount
So 175/2500 which will give you 0.07
0.07 x 100 will give you 7%

Mclane is playing a game where you get 5 points for correct answers and lose 3 points for incorrect answers. If he gets 6 questions correct and 7 questions incorrect, what was his final score?
Answer:
9
Step-by-step explanation:
final score = total points for correct answer - total points for wrong answer
total points for correct answer = 5 x 6 = 30
total points for wrong answer = 7 x 3 = 21
30 - 21 = 9 points

Which number is an integer?
Answer:
Step-by-step explanation:
Can you please specify on that question
Answer:
Integers are numbers that include the negatives, zero and positives.
Step-by-step explanation:
If you ever get confused there's a big circle chart to help you remember look for it online!! What I use to remember is visualizing a number line!
First is the real numbers, so the numbers we were taught since we were little like 1, 2 ,3, 4, 5, 6 and so on. So that's the first part of the number line.
Next is the whole numbers so you just add a zero to that number line. Whole numbers is just all of the real numbers + the number zero.
Then it's the integers so you add the left side of that number line. Integers are real numbers, whole numbers, and negatives. So basically on the number line it's the negatives , zero, and the positives.
Last it's the radicals so all parts of a number like fractions and decimals. So you can add .5 in between the numbers of that numberline.
I hope this strategy helped and if it didn't here's that circle chart!!
I really hope this did help tho!!
Can you maybe put up the explanation too and not just the answer? Thank you
Hope it helps you! .........
