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).

12

Answers

Answer:

Step-by-step explanation:

10.   To solve for this, use the formula: 180*(n-2)

So, 180(n-2) = 2,340

Once n is solved for, that is the number of sides

11. Use the formula:

[180*(n-2)]/n

    (n represents the number of sides)

12. Think of the sum of all interior angles in a quadrilateral

10. The sum of two numbers is 102. One number is three less than twice the other.
What are the two numbers?

Answers

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!

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?

Answers

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%

What are like and unlike terms in an expression?

In Algebra, the like terms are defined as the terms that contain the same variable which is raised to the same power. In algebraic like terms, only the numerical coefficients can vary. We can combine the like terms to simplify the algebraic expressions

Given here: The expression as 7a-4a

Now combining the like terms we get

7a-4a=3a

for a=8

we have

3a=3×8

   =24

Hence, The value of the expression for x=8 is 24

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? *

Answers

Answer:

(x, y) → (4x, 4y)

Step-by-step explanation:

Dilation is applied by the rule:

(x, y) → (kx, ky), where k is the scale factor

We have

(x, y) = (-2, 3) and (kx, ky) = (-8, 12)

Substitute and solve for k

-8 = -2k and 12 = 3k  ⇒ k = 4

So the rule is

(x, y) → (4x, 4y)

Explain the steps when solving for the variable y
12x+2y=18

Answers

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
