PLEASE!! HELP!!! ALL MY POINTS!!
Answer:
1/16
Step-by-step explanation:
The equation of a direct proportion is
y = kx
Let amount of fertilizer = y and amount of peat moss = x
We have x = 12 when y = 3/4
3/4 = k * 12
k = (3/4)/12 = 3/4 * 1/12 = 3/48 = 1/16
y = 1/16 x
The constant of proportionality is 1/16.

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

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.
How many unit cubes with side lengths of 1/2 unit are needed to fill the right rectangular prism?
Answer:
4
Step-by-step explanation:
Which shape has a greater perimeter?
Answer: Shape B, which is the thin and long rectangle.
Step-by-step explanation:
Shape A:
4 + 4 + 8 + 8
4+4 = 8
8 + 8 = 16
16 + 8 = 24
Shape A has a perimeter of 24.
Shape B:
2 + 2 + 11 + 11
2 + 2 = 4
11 + 11 = 22
22 + 4 = 26
Shape B has a perimeter of 26.
4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?
please drop an explanation, and equation thanks!
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.

3x + 2 = -55 i need all the steps
Answer:
-19
Step-by-step explanation:
3x+2 = -55
-2 -2
3x = -55-2
3x = -55+-2
3x = -57
/3 /3
x=-19
Answer:
-19
Step-by-step explanation:
[tex]3x + 2 = -55[/tex]
[tex]3x = -55[/tex]
[tex]-2[/tex] (2 is negative because it was moved to the other side of the equation)
[tex]3x/3 = -57/3[/tex] (Divide both sides of the equation by 3 to isolate x.)
[tex]x = -19[/tex]

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
