Step-by-step explanation:
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.

Answer:
1
1
0
0
Step-by-step explanation:
here´s and example for 1
1⁵
1x1x1x1x1=1
so 1 raised to the power of any number is 1
1 multiply by itself any number of times is 1
here´s an example for 0
0⁴
0x0x0x0=0
hence, the vale of 0 raised to any power is 0.
0 multiplied by itself any number of times is 0

F=Friday
S=Saturday
P(F or S)= 20/90+22/90-20/90=22/90
22/90 as percentage is 24.44 percent
Answer:
For Friday, 22% of the check in's happened on that day. For Saturday, 24% of the check in's happened on that day. For both days combined, 46.66% of the check in's happened for both.
Step-by-step explanation:
Overall there were 90 check ins. Since 20 happened on Friday, it would be 20/90, which is 22%. Saturday, 22 check ins happened, so it would be 22/90, which is 24%. Overall, between Friday and Saturday, 42 check in's happened, so it would be 42/90, which is 46.66%.

Seth deposited $40 in a savings account that earns 5% interest each year. How much interest will he earn in 1 year?
Answer:
$2
Step-by-step explanation:
The formula for simple interest is i = p*r*t, where r is the annual interest rate expressed as a decimal fraction. Here the principal is $40 and the elapsed time is 1 year. The amount of interest collectible after 1 year is thus:
i = ($40)(0.05)(1) = $2
Answer:
$2

Which expression is equivalent to 3(4m - 2) - 2(m + 5)
A. 10m - 16
B. 14m + 4
C. -16m + 10
D. 12m - 6
Answer:
A. 10m - 16
Step-by-step explanation:
First, distribute 3 to all terms within the corresponding parenthesis, and -2 likewise:
3(4m - 2) =
3 * 4m = 12m
3 * -2 = -6
3(4m - 2) = 12m - 6
-2(m + 5) =
-2 * m = -2m
-2 * 5 = -10
-2(m + 5) = -2m -10
Combine like terms:
12m - 6 -2m - 10
12m - 2m - 6 - 10
(12m - 2m) + (-6 - 10)
10m - 16
A. 10m - 16 is your answer.
~
Answer:
10 m - 16 (Answer A)
Step-by-step explanation:
We use distributive property to eliminate parenthesis:
12 m - 6 - 2 m -10
and now combine like terms:
[12 m - 2 m] - 6 - 10
10 m - 16
Therefore, answer option A. is the correct one

What is the slope of the line that goes through the points (6, 4) and (8, -2)?
-6
-3
-1/3
3
Answer:
-3
Step-by-step explanation:
(6, 4) and (8, -2)
Slope:
m=(y2-y1)/(x2-x1)
m=( -2 -4)/(8-6)
m = (-6)/2
m = -3
Answer:
-3
Step-by-step explanation:
(6, 4) and (8, -2)
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-2 - 4) / (8 - 6)
Simplify the parentheses.
= (-6) / (2)
Simplify the fraction.
-6/2
= -3
This is your slope.

Which are equivalent ratios to 3:4?
Check all that are true.
6:8
15:20
9:12
9:15
16:20
Answer:
6:8
15:20
9:12
How?
3:4*2=6:8
3:4*5=15:20
3:4*3=9:12
The equivalent ratio to the given to 3:4 are 6:8, 15:20 and 9:12
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator. Thus, a = px, b = qx
We are given the ratio as; 3:4
3: 4 x 2 = 6 : 8
3: 4 x 5 = 15 : 20
3: 4 x 3 = 9 : 12
Therefore, the equivalent ratio to the given to 3:4 are 6:8, 15:20 and 9:12

What property of equality would you use to solve the equation n/4 = 16.
Answer:
Multiplication Property of Equality.
Step-by-step explanation:
Isolate the variable, n. Note the equal sign, what you do to one side, you do to the other.
Multiply 4 to both sides of the equation:
(n/4) * 4 = (16) * 4
n = 16 * 4
n = 64
n = 64 will be your answer.
