Triangle NGM is reflected across the x-axis, and is dilated by a factor of
\(2 \frac{1}{2} \)
what are the coordinates of vertices N'G'M'
The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).
From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).
Scale factor = \(2\frac{1}{2}\)
= 2.5
The reflection of point (x, y) across the x-axis is (x, -y).
Here, N(-4, 6)→(-4, -6)
M(-6, 2)→(-6, -2)
G(-2, 4)→(-2, -4)
Now, with scale factor 2.5, we get
(-4, -6)→2.5(-4, -6)→N'(-10, -15)
(-6, -2)→2.5(-6, -2)→M'(-15, -5)
(-2, -4)→2.5(-2, -4)→G'(-5, -10)
Therefore, the coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.
Hello everyone if you could help me that would be awesome
I need some help for this and the graph won’t let you use decimals as the answer. Tip: 1/3 = 0.3
.
Answer:
\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)
See attachment for the graph of the equation.
Step-by-step explanation:
Given equation:
\(y=\dfrac{1}{3}x\)
To complete the table, find the corresponding values of y by substituting each given value of x into the equation.
\(x=6 \implies y=\dfrac{1}{3}(6)=\dfrac{6}{3}=2\)
\(x=12 \implies y=\dfrac{1}{3}(12)=\dfrac{12}{3}=4\)
\(x=18 \implies y=\dfrac{1}{3}(18)=\dfrac{18}{3}=6\)
Therefore the completed table is:
\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)
To graph the equation, plot the ordered pairs on the given coordinate plane:

Answer:

Step-by-step explanation: When selecting ratios for two variables (boys and girls) the two sides of the ratio must add up to be a factor of the total student count. The factors of 28 include 14, 7, 4, and 2. (1 + 1 = 2), (2 + 3 = 5), (3 + 4 = 7), and (1 + 3 = 4). 5 is the only nonfactor and cannot be the ratio of boys to girls, thus making 2 : 3 the correct answer.

find the surface area of the composite figure - image attached,, need answer now!!
Answer:
Surface Area = 392 cm²
Step-by-step explanation:
Green (front):
SA = 1/2bh
= 1/2 (12) (8)
= 48 cm²
Green (left side):
SA = bh
= 5 (10)
= 50 cm²
Green (right side):
SA = bh
= 5 (10)
= 50 cm²
Green (back):
SA = 1/2bh
= 1/2 (12) (8)
= 48 cm²
Blue (front):
SA = bh
= 12 (4)
= 48 cm²
Blue (left side):
SA = cm²
= 5 (4)
= 20 cm²
Blue (right side):
SA = bh
= 5 (4)
= 20 cm²
Blue (back):
SA = bh
= 12 (4)
= 48 cm²
Blue (bottom):
SA = bh
= 12 (5)
= 60 cm²
Total:
48 + 50 + 50 + 48 + 48 + 20 + 20 + 48 + 60 = 392 cm²

An object has a mass of 17 grams.
What is its weight in ounces?
Use 1 ounce=28.35 gram to write the conversion facto
Step-by-step explanation:
In order to determine the weight of an object in ounces, we need to convert its mass from grams to ounces using the conversion factor of 1 ounce = 28.35 grams. Since the mass of the object is 17 grams, we can use the conversion factor to calculate its weight in ounces as follows:
17 grams * (1 ounce / 28.35 grams) = 0.6 ounces
Therefore, the weight of the object in ounces is 0.6 ounces. The conversion factor used in this calculation is 1 ounce = 28.35 grams.

Bob is packing a suitcase to take on an airplane. A suitcase and its contents can weigh at most 50 pounds before the airlines charge extra fees. Bob's suitcase weighs 10 pounds when it is empty, so he can put 40 pounds of clothes in the suitcase. Bob's shirts weigh 0.5 pounds each and his pants weigh 2 pounds each.
(1)Write an equation that would model how many pounds of clothing Bob can pack.
(2)Rewrite the equation to model the number of pants Bob can pack in terms of the number of shirts.
Answer:
1. 10x + 40 = 50
2. 10x + 2 + 0.5 = 40
Step-by-step explanation:
1. If bob's suitcase is 10lb. by itself then that is 10.
His limit of content and suitcase is 50lb.
His shirts weigh 0.5lb each.
His pants weigh 2lb each.
10x + 40 = 50
2. 10x + 2 + 0.5 = 40
