Answer:
1) 9(x - 3) = 9x - 27. So, 1) applies.
2) 3(3x - 9) = 9x - 27. So, 2) applies.
3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.
4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.
5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.
Step-by-step explanation:
1) 9(x - 3) = 9x - 27. So, 1) applies.
2) 3(3x - 9) = 9x - 27. So, 2) applies.
3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.
4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.
5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.
The expressions that are equivalent to 9x - 27 are:
9(x - 3)
3(3x - 9)
To determine which expressions are equivalent to 9x - 27, let's simplify each of the given options:
9(x - 3):
Expanding the expression, we get 9x - 27.
This expression is equivalent to 9x - 27.
3(3x - 9):
Expanding the expression, we get 9x - 27.
This expression is equivalent to 9x - 27.
x(9x - 3):
Expanding the expression, we get 9x² - 3x.
This expression is NOT equivalent to 9x - 27.
3(3x - 7):
Expanding the expression, we get 9x - 21.
This expression is NOT equivalent to 9x - 27.
3(x - 9):
Expanding the expression, we get 3x - 27.
This expression is NOT equivalent to 9x - 27.
Therefore, the expressions that are equivalent to 9x - 27 are:
9(x - 3)
3(3x - 9)
So, the correct options are 1 and 2.

Answer:
x+4 and y+3
Step-by-step explanation:
Both the x and y values move in positive directions from the first triangle to the second.
Answer:
(x+4, y+3)
Step-by-step explanation:
First, choose a point to follow (I chose C). The coordinates of C are (-2, -5). The coordinates of C' are (2, -2). To get to 2 from -2, you have to add 4. Move left or right because it's on the x-axis. Since it's moving you the right, it is positive. So, x+4 is the first part. To get from C to C', you have to move up to follow the y-axis, meaning another positive. Counting the units from (2, -5), because that is the point after x+4, there are 3 units. So, (x+4, y+3).

Cody increased the amount of money he saves each week from $40 to $75. By
what percentage did Cody increase the amount of money he saves?
Answer:
So Cody increase his savings by 87.5%
Step-by-step explanation:
We are given Cody's original savings = $40
We are given his new savings total = $75
Now, in order to find out the percentage we have to first find out by how much did he increase his savings:
Increase in savings = $75 - $40 = $35
So now we have the increase in savings we can find out the percentage:
[tex]increase(\%) \: = \frac{increase \: in \: savings}{original \: savings} \times 100[/tex]
Now we plug in our values that we found:
[tex]increase(\%) = \frac{35}{40} \times 100\\ increase(\%) = 87.5\%[/tex]
So Cody increase his savings by 87.5%
10. The sum of two numbers is 102. One number is three less than twice the other.
What are the two numbers?
Answer:
(2n -3) + n = 102
2n - 3 + n = 102
3n - 3 = 102
3n = 105
n = 35 (the first number)
SO...
The other number is (2 x 35) - 3 =
70 - 3 = 67 (the second number)
The numbers are 35 and 67.
35 + 67 = 102 CHECK!

A triangle is dilated with a center of dilation at the origin. Point P is on the figure and P' is the corresponding point on the image of the dilation. Point P is at (-2, 3) and P' is at (-8, 12). Which rule best represents the dilation? *
Answer:
(x, y) → (4x, 4y)Step-by-step explanation:
Dilation is applied by the rule:
(x, y) → (kx, ky), where k is the scale factorWe have
(x, y) = (-2, 3) and (kx, ky) = (-8, 12)Substitute and solve for k
-8 = -2k and 12 = 3k ⇒ k = 4So the rule is

Explain the steps when solving for the variable y
12x+2y=18
Answer:
Simplifying
12x + 2y = 18
Solving
12x + 2y = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
12x + 2y + -2y = 18 + -2y
Combine like terms: 2y + -2y = 0
12x + 0 = 18 + -2y
12x = 18 + -2y
Divide each side by '12'.
x = 1.5 + -0.1666666667y
Simplifying
x = 1.5 + -0.1666666667y
Answer:
Hi
Step-by-step explanation:
First, you need to subtract both sides by 12x
12x+ 2y=18
-12x -12x
That will give you: 2y= 18-12x
Next, you need to deviede both sides by 2
2y/2= 18-12x/2
That gives you the answer:
y= 18-6x
