Answer:

1.11

Step-by-step explanation:

The Slope is defined as the rate of change.

In this case,

Slope = -200+100/-180+90

         = -100/-90

         = 10/9

         = 1.11

Answer:

1/5

1/3

Step-by-step explanation:

For the first problem:

5/7 of ... is 1/7

so

5/7 of x is equal to 1/7

so

(5/7)x = (1/7)

so

x = (1/7)/(5/7)

so

x = 1/5

For the second problem:

5/7 of ... is 5/21

so

5/7 of x is equal to 5/21

so

(5/7)x = (5/21)

so

x = (5/21)/(5/7)

so

x = 1/3

Answer:

Step-by-step explanation:

Combine like terms:

-4x - 9x = (-4 - 9)x = -13x

4x - (-9x) = 4x + 9x = (4 + 9)x = 13x

-4x + 9x = (-4 + 9)x = 5x

4x - 9x = (4 - 9)x = -5x

Answer: Im going to say 3 over 5 and 8

Step-by-step explanation:

Answer: Let's start by writing down coordinates of all points:

A(0,0,0)

B(0,5,0)

C(3,5,0)

D(3,0,0)

E(3,0,4)

F(0,0,4)

G(0,5,4)

H(3,5,4)

a.) When we reflect over xz plane x and z coordinates stay same, y coordinate  changes to same numerical value but opposite sign. Moving front-back is moving over x-axis, moving left-right is moving over y-axis, moving up-down is moving over z-axis.

A(0,0,0)

Reflecting

A(0,0,0)

B(0,5,0)

Reflecting

B(0,-5,0)

C(3,5,0)

Reflecting

C(3,-5,0)

D(3,0,0)

Reflecting

D(3,0,0)

b.)

A(0,0,0)

Moving

A(-2,-3,1)

B(0,-5,0)

Moving

B(-2,-8,1)

C(3,-5,0)

Moving

C(1,-8,1)

D(3,0,0)

Moving

D(1,-3,1)

Answer:

It seems like this one is more of an estimate based off the graph so I would go with either 1 or 0 but most likely 1

Step-by-step explanation:

Option D is correct  (x, y) → (2.5x, 2.5y).

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given, Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral EFGH on the graph below.

Since Scale factor:

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

In our case,

A dilation of 2.5 because side AB is 4 units and EF is 10 units and if you divide 10/4 will get you with your scale factor.

thus, Scale factor is 2.5

Therefore,  best represents the dilation that was applied to quadrilateral ABCD to create quadrilateral EFGH is D. (x, y) → (2.5x, 2.5y)

Step-by-step explanation:

You can find the answer by doing the keep change flip method. So keep the 6, chnage the sign to a multiplication sign, then flip the 2/3 to 3/2. Then you multiply and you get 18/2 which simplifies to 9.

Answer:

-14

Step-by-step explanation:

Answer:

-14, fourth choice

Step-by-step explanation:

absolute value is represented with this |x|, the 2 lines

The absolute value for a real number, in this case -14, is the non-negative value without regard to its sign. So the absolute value of -5 would be 5, and the absolute value of 7 would still be 7

In this case there's no 14, so u can choose -14

Answer:

the equation x - 18 = 4(x - 18)

Step-by-step explanation:

x - 18 = 4x - 72

x - 4x = - 72 + 18

- 3x = - 54

x = 54/3

x = 18

Step-by-step explanation:

Answer:

The answer is A

Step-by-step explanation:

Express the number in scientific notation as real numbers:

[tex]9.4 \times {10}^{ - 8} = 0.000000094 \\ 9.25 \times {10}^{ - 6} = 0.00000925 \\ 2.5 \times {10}^{3} = 2500 \\ 7 \times {10}^{3} = 7000[/tex]

So, from least to greatest;

[tex]0.000000094 - 0.00000925 - 2500 - 7000[/tex]

9.4 x 10^-8, 9.25 x 10^-6, 2.5 x 10^3, 7 x 10^3 (first option)
