Which graph shows a dilation?

Answer:

4

Step-by-step explanation:

The LCM 

The LCM of 12,18,2412,18,24 is 2⋅2⋅2⋅3⋅3=722⋅2⋅2⋅3⋅3=72.

the HCF

The prime factorization of 36 is

2 x 2 x 3 x 3

The prime factorization of 54 is

2 x 3 x 3 x 3

2 x 3 x 3 = 18

72÷18=4

Answer:

y= 3

x=3

Step-by-step explanation:

4(2y-3)-2y=6

8y-12-2y=6

6y-12=6 (add the 12 on both sides)

6y=18 (divide the 6 out)

y=3

solve for x.

x=2(3)-3

x=6-3

x=3

Answer: C) 28

Explanation:

The triangles are congruent, so the corresponding pieces are congruent. Specifically the angles on the right side are congruent, as shown by the tickmarks they have in common.

Set those two expressions equal to one another. Solve for x.

2(x+2) = 60

2x+4 = 60

2x = 60-4

2x = 56

x = 56/2

x = 28

The correct value of the variable x is,

⇒ x = 28

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In the diagram,

ΔGEF and ΔHEF are congruent.

Hence, We can formulate;

⇒ 2 (x + 2) = 60°

⇒ 2x + 4 = 60

⇒ 2x = 60 - 4

⇒ 2x = 56

⇒ x = 28

Thus, The correct value of the variable x is,

⇒ x = 28

Answer:

$282.5

Step-by-step explanation:

$7.50 * 3= $22.5

$22.5 is the total money that is charged from Javier's bank account.

Subtracting that from his $305, we get:

$305 - $22.5 = $282.5

Therefore, Javier has $282.5 in his bank account at the end of three months.

Hello 928747!

So Javier has $305 to begin with but his bank charges him $7.50 if he has less than $500 in his account.

305 < 500

So, since he has less than $500 he will lose $7.50

305 - 7.50 = 297.50

So after they take $7.50, he will have $297.50

but he had less than $500 for 3 months so they would take x 3 more than $7.50

7.50 x 3 = 22.50

305 - 22.50 = 282.50

After three months, Javier will have $282.50

Answer: Multiply or Divide

Step-by-step explanation: You can multiply or divide by the cube of the scale factor. To decide if you should multiply or divide, you should consider the value of the scale factor and if you are going from a larger to a smaller figure, or a smaller to a larger.

Answer:

Diagonal=11.3m

Area of square (A) =1/2*d^2

=1/2*(11.3)^2

Answer:

No

Step-by-step explanation:

For a relation to be a function it must have a unique x-value for every y-value. This means that in a function x-values cannot repeat. In this relation, the x-value repeats multiple times, so it is not a function. It is also a vertical line, and vertical lines can never be functions since the x-value is constant and therefore repeats.

Answer:if y=0

Step-by-step explanation: view y as 0, so you have 2*0*(-8+0+7)=0

every number multiplied by 0 is 0 so 2*0 is 0 then in the brackets you will have -1. So the final line is 0*-1=0 like I said every number multiplied for 0 is 0 the equation is true for y=0

Answer:

see explanation

Step-by-step explanation:

The zero product property applies to the product of factors equal to zero

For example

a × b = 0

Since the product of the 2 numbers is zero , then one of the numbers must be zero, that is

a = 0 or b = 0

This can be applied to the product

2y(- 8y + 7) = 0

The 2 values being multiplied are 2y and (- 8y + 7)

Thus one or the other must equal zero, so solve both

2y = 0 ⇒ y = 0, or

- 8y + 7 = 0 ⇒ - 8y = - 7 ⇒ y = [tex]\frac{-7}{-8}[/tex] = [tex]\frac{7}{8}[/tex]

Answer:

x = -1 ± √6

Step-by-step explanation:

[tex]x^{2} +2x - 5 = 0[/tex]

Lets use the quadratic formula → [tex]x = \frac{-b + \sqrt{b^{2} - 4ac} }{2a} \:or \frac{-b - \sqrt{b^{2}- 4ac } }{2a}[/tex]

So ,

[tex]x = \frac{(-2) + \sqrt{(2)^{2} - (4\times1\times-5) } }{2\times1} \:or \frac{(-2) - \sqrt{(2)^{2} - (4\times1\times-5) }}{2\times1}[/tex]

[tex]=> x = \frac{-2 + \sqrt{24} }{2} \:or \frac{-2-\sqrt{24} }{2}[/tex]

[tex]=> x = \frac{-2 + 2\sqrt{6} }{2} \:or \frac{-2 - 2\sqrt{6} }{2}[/tex]

Lets take 2 common from numerator.

[tex]=> x = \frac{2(-1 + \sqrt{6}) }{2} \:or \frac{2(-1-\sqrt{6}) }{2}[/tex]

Cancelling 2 from numerator & denominator gives

[tex]x = (-1+\sqrt{6} ) \: or (-1 - \sqrt{6} )[/tex]

Step-by-step explanation:

The gradient of the perpendicular line is 3.

We have y = 3x + c.

When x = 4, y = 2.

=> (2) = 3(4) + c, c = -10.

Hence the line equation is y = 3x - 10.

Answer:

The rule for the linear function will be:

[tex]f(x) = -2x+5[/tex]

Step-by-step explanation:

We know that linear function can be represented using the slope-intercept formula

y = mx+b

where m is the slope and b is the y-intercept

Given the function is linear

Taking two points from the table to determine the slope

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:3\right),\:\left(x_2,\:y_2\right)=\left(2,\:1\right)[/tex]

[tex]m=\frac{1-3}{2-1}[/tex]

[tex]m=-2[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = -2 and the point (1, 3)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 3 = -2 (x-1)[/tex]

[tex]y-3 = -2x+2[/tex]

adding 3 to both sides

[tex]y-3+3 = -2x+2+3[/tex]

[tex]y = -2x+5[/tex]

or

[tex]f(x) = -2x+5[/tex]

Therefore, the rule for the linear function will be:

[tex]f(x) = -2x+5[/tex]

Answer:

A

Step-by-step explanation:

Well, this isn't too hard.

Since the left is the negative side (R) and the right is the positive side (S), a positive and a negative with the same number will equal zero if only one of them are negative.

You ALWAYS subtract when there's two different signs.

Answer: See explanation

Step-by-step explanation:

Since Veronica buys 2 games for $30.00 each and a game controller for $19.59. The total cost to be paid will be:

= (2 × $30.00) + $19.59

= $60.00 + $19.59

= $79.59

Since Veronica lives in San Jose, California, where sales tax is 9.25%, the sales tax will be:

= 9.25% × $79.59

= 0.0925 × $79.59

= $7.36

Total amount paid = $79.59 + $7.36 = $86.95
