Answer:
D is correct
Step-by-step explanation:
The opposite of a negative number is the positive version of it which is 3.5 and the absolute value of a number is always the positive version of a number which would make it also 3.5. For example absolute value of -4 is 4 and absolute value of 5 is 5.

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.

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?
please drop an explanation, and equation thanks!
Answers
To do this you know 4/9=2$ so now you want to know 1=x$
When you do this you get $5
Answer:
1 kg of baking soda costs $4.50.
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
4/9 kg $2
------------- = --------------
1 kg x
Multiplying both numerators by 9, we get:
4 kg $18
------------ = ---------
1 kg x
Cross-multiplying, we get 4x kg = $18-kg. Solving for x, we get:
$18-kg
x = -------------- = $4.50
4kg
1 kg of baking soda costs $4.50.

Rewrite each estimate so they all have the same power of 10.
Dogs: 69,900,000
Cats: 36,100,000
Birds: 8,300,000
Answers
Answer:
question 1 part a =
estimated number of dogs
=6.99 × 107
= 6.99 • 10,000,000
= 69,900,000
estimated number of cats
= 3.61 × 107
= 3.61 • 10,000,000
=36,100,000
estimated number of birds
= 8.3 × 106
= 8.3 • 1,000,000
= 8,300,000
part b = total population of pet dogs, cats, and birds
= 69,900,000 + 36,100,000 + 8,300,000
= 114,300,000
question 2 part a =
The estimated number of dogs is 6.99 x 10^7 .
The estimated number of cats is 3.61 x 10^7.
The estimated number of birds is 8.3 x 10^6.
The power of 10 in 8.3 x 10^6 is 6, which is less than the power of 10 in the other two numbers. To make the calculation simpler, convert this number so the exponents are all the same.
Multiply and divide 8.3 x 10^6 by 10 to increase its exponent by 1:
8.3 x 10^6 = 10/10 x 8.3 x 10^6
= 8.3/10 x 10^6 x 10
= 0.83 x 10^7
part b =
total number of pet dogs, cats, and birds
=
6.99 × 107 + 3.61 × 107 + 0.87 × 107
=
(6.99 + 3.61 + 0.83) • 107
=
11.43 • 107
part c =
No. The sum from part B is not in scientific notation.
The total number of pet dogs, cats, and birds is 11,43 x 10^7. To express the number in scientific notation, the decimal point must be moved one digit to the left. To do that, divide and multiply the number by 10:
10/10 x 11.43 x 10^7 = 11.43/10 x 10^7 x 10
= 1.143 x 10^8
Written in scientific notation, the total number of pet dogs, cats, and birds is 1.143 x 10^8.
question c = They are the same. If you convert the number in standard form from question 1 to scientific notation, it is the same as the number in scientific notation found in question 2.

The Scientific Notation
Dogs: 6.99 x [tex]10^8[/tex]
Cats: 3.61 x [tex]10^8[/tex]
Birds:0.083 x [tex]10^8[/tex]
What is Scientific Notation?Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Also, the numbers in the millions place after the decimal required to be represented in a simpler format. As a result, representing a few integers in their expanded form is challenging. As a result, we employ scientific notation.
Given:
We have to change the number in Scientific Notation in which only one significant number will be before the decimal and remaindering raise to power of 10.
First, Dogs: 69,900,000 whose Scientific Notation is
= 6.99 x [tex]10^8[/tex]
Second, Cats: 36,100,000 whose Scientific Notation is
= 3.61 x [tex]10^8[/tex]
Third, Birds: 8,300,000 whose Scientific Notation is
= 8.3 x [tex]10^6[/tex]
= 0.083 x [tex]10^8[/tex]

Which expression is equivalent to 3(4m - 2) - 2(m + 5)
A. 10m - 16
B. 14m + 4
C. -16m + 10
D. 12m - 6
Answers
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
