Its really hard !!!!!!!!!!!!!!!

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).

Answer:

1.75a - 11

Step-by-step explanation:

Remember your order of operations, first you want to start inside the parantheses. Nothing can be simplified there so move on to multiplication.

Distribute (mutiply) ¾ with (5a - 16) as well as -⅓ with (6a - 3) to get

3.75a - 12 - 2a + 1

Combine like terms, so 3.75 with -2a as well as -12 with 1.

1.75a - 11

Which you could also write as

⁷⁄₄a - 11 or 1¾a - 11

Answer:

Andre should stop at (-3 , 6.5)

Step-by-step explanation:

The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3

The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.

Answer: The radius of the circle is 2

Step-by-step explanation: To find the radius of the circle, we need to rewrite the equation in the standard form of a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.

To do this, we need to complete the square for both x and y terms. First, we divide both sides by 4 to simplify the coefficients:

x^2 + 5x + y^2 - 6y + 21/4 = 0

Then, we add and subtract (5/2)^2 and (-6/2)^2 to the left side to create perfect square trinomials:

(x^2 + 5x + 25/4) + (y^2 - 6y + 9) - 25/4 - 9 + 21/4 = 0

Next, we factor the trinomials and simplify the constants:

(x + 5/2)^2 + (y - 3)^2 - 13/4 = 0

Finally, we add 13/4 to both sides and get the standard form:

(x + 5/2)^2 + (y - 3)^2 = 13/4

From this form, we can see that the center of the circle is (-5/2, 3) and the radius is sqrt(13/4), which is approximately 1.8. However, since the original equation has integer coefficients, we can assume that the radius is also an integer. Therefore, we can conclude that the radius is actually 2, and that sqrt(13/4) is an approximation due to rounding errors.

Hope this helps, and have a great day! =)

Step-by-step explanation:

You need to manipulate the equation into the standard form of a circle:

(x-h)^2 + (y-k)^2 = r^2

4x^2 + 20 x  + 4y^2 - 24 y   = -21       < ==== divide through by 4

x^2 + 5x      +  y^2 - 6y      = - 21/4    < ==== 'complete the square' for x and y

(x+2.5)^2    +   (y-3)^2   = -21/4   + 6.25  + 9     < ===simplify

(x+2.5)^2    +  (y-3)^2   = 10        10 = r^2     so  r = sqrt (10)    

Answer: for the first ss, c > 32

we can say this is true because she needs to buy MORE THAN 8 pound of candy, for 4 dollars each, given that the question wants us to find the amount of MONEY she spends on the candy, you have to factor in that each pound of candy equals 4 dollars, 4 x 8 = 32, but it needs to be a greater than inequality because she wants to buy MORE THAN 8 pounds of candy.

Answer:

Step-by-step explanation:

1. 3x + 2y - 2x + y + 12 is equivalent to x + 3y + 12

2. 4y + 3y + 3x - 6y - 10 - 2 is equivalent to 3x + y - 12

3. x + 3y + 2x - 3x + 7 + 5 is equivalent to 3y + 12

4. I do not know unfortunately

Answer:

See attached image

Step-by-step explanation:

To solve this, first simplify the compound expressions - the ones with multiple x, y terms and see which of the other expressions matches the simplified expression

I will tell you how to solve one of the more complex expressions; the technique is the same for the rest

Let's take the very last expression
4y + 3y + 3x - 6y -10 - 2

To simplify,

group like terms:

=(4y + 3y - 6y) + 3x +(-10 -2)

= y + 3x - 12

Rewriting with x before y gives
3x + y - 12

and there is a matching 3x + y - 12

4y + 3y + 3x - 6y -10 - 2   ⇔  3x + y - 12

Equation refers to a mathematical expression containing the equals sign. Algebra is frequently used in equations. In mathematics, algebra is employed when the exact value of a calculation cannot be determined.

An equation is merely a numerical statement that can substitute a variable for an unknown value. A variable is a letter that is used to represent an unknown value. It can be any letter, although the letter x is the most common.

All formulas are equations. Some equations are not formulas. Equations are intended to be solved for a certain variable.

The variable of this problem is mean score, categories and total score. From this variable, identify each function to find the equation then the result.

Step-by-step explanation:

Area of the triangle is (12 x 4)/2 = 12 x 4 x 1/2 = 24

Step-by-step explanation:

0.5% of w is 12 is what they are asking

0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is

\(12 = 0.005 \times w\)

Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite

\(w = \frac{12}{0.005} = 2400\)

Answer:

0.5% of w is 12 is what they are asking0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part isNow to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite

Answer:

7x + 96 = 180

Step-by-step explanation:

We are given that the right side of the equation should be 180 because that is equal to the sum of the triangle's interior angle measures.

We can solve for the left side by adding the triangle's interior angle measures.

(2x + 1) + (5x + 5) + 90

Remember that a right angle is 90°.

All we need to do from here is combine like terms:

= (2x + 5x) + (1 + 5 + 90)

= 7x + 96

So, the equation that represents the model is:

7x + 96 = 180

Answer:

C) 7x + 96° = 180

Step-by-step explanation:

their is one right angle and 2 equations. The sum of the interior angle is 180

90° + 2x + 1 + 5x + 5 = 180

Combine like terms

90 + 1 + 5 = 96

2x + 5x = 7x

7x + 96° = 180
