Erik transformed the equation y = 2(x − 2)^2 + 5 from vertex form to standard form. His steps are shown below. Is Erik's work correct? If not, identify and correct his error.
y = 2(x − 2)^2 + 5
y = 2(x^2 − 4x + 4) + 5
y = 2x^2 − 8x + 8 + 5
y = 2x^2 − 8x + 13
A. No. The error is in the second line: the expanded form of (x − 2)^2 is x^2 − 4.
B. No. The error is in the third line: the product of 2 and x^2 − 4x + 4 is 2x^2 − 4x + 4.
C. No. The error is in the fourth line: the sum of 8 and 5 is 12.
D. Yes. Erik is correct in his transformation from vertex form to standard form.

1. Determine the equation for the line of
best fit in slope-intercept form.
2. Include the two points you used to find the slope.
3. Verify your equation is correct by substituting a given point on the line into your equation.
Answer:
y=
[tex] \frac{2}{15} [/tex]
x+10
Step-by-step explanation:
we know the y-intercept : (0,10)
picking another point on the line, (2,25)
finding slope is
[tex] \frac{y2 - y1}{ x2 - x1} [/tex]
so inserting that together is:
[tex] \frac{2 - 0}{25 - 10} [/tex]
that equals to,
[tex] \frac{2}{15} [/tex]
and since we already have the y-intercept you take the 10 to replace the b in the equation y=x+b
meaning x = slope and b = y-intercept
equation all together
y =
[tex] \frac{2}{15} [/tex]
x + 10
At West Painting, they get about three calls a day asking for an estimate of the cost for having the interior of a house painted. To write up an estimate for the cost of a job, they need to know how much paint a job will take. If they average painting 3/4 of a room with 2/5 of a gallon of paint, then they can paint, on average,
rooms per gallon.

Answer:
Skewed right.
Step-by-step explanation:
The graph is not symmetric because it's not an exact mirror of each side if you drew a line in the center. If the graph has highpoints on the left side and is leaning down to the right, it's skewed right. Same thing vice versa.

Answer: 5/13
Step-by-step explanation:
If you add 3 + 8 + 2 = 13
And the probability of not getting a striped marble would be 5/13. Please rate 5 stars.
Answer:
(5 13)
Step-by-step explanation:
This is easy, So if you add 8+3+2=13
The last option is 8/13 because it knows that is answer if they did include 8 marbles but they are not so you add 3 and 2 which 5. You have 5 out of 13 chances!
Your Welcome! :)
Help me plz I don't understand math today?
Answer:
C-42
B-156
A-66
Step-by-step explanation:
Now I'm not a 100% sure on this but I'm pretty confident.
The easiest on to find was C because on the opposite side was 24 so the side we are working with must equal 24. In order to find the answer I did 24 + 18 and got 42. That means C = 42.
The next one I found was B. A straight line is 180 degrees so I subtracted 24 from 180 and got 156.
Finally I found A. This was considerably the quickest on to find for me because of all the other measurements I found and the 90 degrees beside the A. I subtracted 90 from the already found 156. I got 156 because if you take out the 90 degree line it would be a mirror image of B. Once I subtracted 90 from 156 I got 66 as my answer.
Answer:
C-42
B-156
A-66

10d + 20 = 100 pls answer quick
Let's solve your equation step-by-step.
10d+20=100
Step 1: Subtract 20 from both sides.
10d+20−20=100−20
10d=80
Step 2: Divide both sides by 10.
10d
/10= 80/10
so d= 80
forgot the zero
Will the graph of y = (7.25x)^2 be stretched or compressed horizontally or vertically when compared to the parent function y = x^2?
A. Because |b| < 1, the graph will be compressed vertically.
B. Because |b| < 1, the graph will be compressed horizontally.
C. Because |b| > 1, the graph will be compressed vertically.
D. Because |b| > 1, the graph will be compressed horizontally.
The correct statement is,
⇒ Because |b| > 1, the graph will be compressed horizontally.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
Parent function is,
⇒ y = x²
And, Function is,
⇒ y = (7.25x)²
Now, The value of b = 7.25 is greater than 1.
Hence, the graph of y = (7.25x)² be compressed horizontally.
Thus, The correct statement is,
⇒ Because |b| > 1, the graph will be compressed horizontally.

Answer:
[tex]\Huge\boxed{x=42}[/tex]
Step-by-step explanation:
Hello There!
The shown angles are supplementary angles.
We know this because a straight line is split into two angles
A straight line creates a 180 degree angle so the sum of the two angles is 180
So we can use this equation to solve for x
180 = 3x + 12 + x
3x + x = 4x
180=4x+12
step 1 subtract 12 from each side
180-12=168
12-12 cancels out
now we have
168=4x
step 2 divide each side by 4
4x/4=x
168/4=42
we're left with x = 42

If F(x) = x² + 5x and G(x) = 2x + 1, find F(5) + G(6). 48 63 107
Answer:
63
Step-by-step explanation:
F(x) = x² + 5x
F(5) = (5)² + 5(5) = 25 + 25 = 50
G(x) = 2x + 1
G(6) = 2(6) + 1 = 12 + 1 = 13
F(5) + G(6) = 50 + 13 = 63

Data Set: 5, 8, 10, 10, 15, 18, 23. What is the upper quartile limit (Q3) of this data set? *
Answer:
15, 18, and 23
Answer:
Q₃ = 18
Step-by-step explanation:
The first step is to find the median
The median is the middle value of the data in ascending order.
5, 8, 10, 10, 15, 18, 23
↑ middle value
median = 10
The upper quartile Q₃ is the middle value of the data to the right of the median, that is
15, 18, 23
↑ middle value
Thus Q₃ = 18

Answer:
a. 6
b. 48
Step-by-step explanation:
It is cut off, but I believe the expression is 3 x 2^t
For a. plug in "1" for "t" so the expression would look like 3 x 2^1. 2^1 is just 2 and 3 x 2 is 6. Answer is 6.
For b. plug in "4" for "t" so the expression would look like 3 x 2^4. 2^4 is 16 and 16 x 3 is 48. Answer is 48.
