Answer:

D. (17,-1)

Step-by-step explanation:

We'll start by canceling out x. To do so, multiple the first equation by -1

-1( x - 2y)=( 19 )(-1)

This gives us:

-x +2y = -19

x + 3y = 14

Add the equations together:

→ 5y = -15

→ y = -1

Plug in y = -1 into an equation:

→ x + 3(-1) = 14

→ x - 3 = 14

→ x = 17

(17,-1)

Answer: (6,1)

Step-by-step explanation:

     Coordinate points are written as (x, y).

     Here is a tip for finding coordinate points on a graph:

[1] Start at the origin, point (0, 0) on the graph

[2] "Walk left/right to the elevator" - this is the x-coordinate value

[3] "Go up/down the elevator" - this is the y-coordinate value

     Here is an example, using your problem:

-> See attached

[Points in Blue] Move one unit right, three units up to (1, 3)

[Points in Red] Move two units right, seven units up to (2, 7)

[Points in Green] Move 6 units right, one unit up to (6, 1)

    -> This means the answer to your problem is the third option, (6, 1)

If you are color blind, let me know and I will rephrase it.

Step-by-step explanation:

so......im not certain about my solution,but this is what I think

f(x)=3x-2

replace f(x) with the latter Y

so its gonna be...y=3x-2

make x subject of the fomula

so is gonna be...y=3x-2

y-2=3x

Answer:

  α = 3π/2

Step-by-step explanation:

To find the coterminal angle, add multiples of 2π until you have an angle in the desired range. Here, you need to add 8π.

  α = -13π/2 + 8π = (-13 +16)π/2 = 3π/2

A change in the scale factor is to occur when an enlargement or a reduction in the dimensions of a building occurs to preserve the relationship between actual and mapped dimensions.

Scale factor is the factor which is used to enlarge or smaller the original figure.

Scale factor is the ratio of representation measurement of the figure to the original figures. An enlargement or a reduction in the dimensions of a building would cause a change in the scale factor.

This can be understood with the following points:

The length is 30 inches.

For a frame of length L and width W, the perimeter is:

P = 2*(L + W).

Here we know that:

P = 96 in

L = 2*W - 6in

Replacing that we get:

96in = 2*( (2*W - 6 in) + W)

Now we can solve that equation for W:

96in = 2*(3W - 6in)

96in/2 + 6in = 3W = 54in

W = (54in)/3 = 18in

The width is 18 inches, then:

L = 2*W - 6in = 2*(18 in) - 6in = 30in

The length is 30 inches.

The approximate area of the triangular base of James’ tank is 3025 in²

To find the approximate area of the triangular base of James' tank, we need to know what scale is.

A scale is the ratio of two dimension. It is given by scale = New dimension/old dimension

Given that the dimensions of James’ tank are each exactly 2 3/4 times the dimensions of Julian’s tank.

The scale of the area of James' tank to the area of triangular base of Julian's tank is S = (2³/₄)²

= (11/4)²

= 121/16

Let

So, scale, S = A/A'

So, making A subject of the formula, we have

A = SA'

A = 121/16 × 400 in²

A = 121 × 25 in²

A = 3025 in²

So, the approximate area of the triangular base of James’ tank is 3025 in²

A, B, C, D. I am intelligent

Answer:

From what we know about percentages and unit rates, the correct options are:

1) 100

2) 1

What is a percent?

Suppose we have an amount A, this would be the 100%.

If we want to know how much a quantity B represents, compared to A, we have:

A = 100%

B = x

where x is a percentage, to find the value of x we compute:

x = (B/A)*100%

While there is a dependence on A, we actually are comparing the term with 100 (because A represents a 100%), so the correct option is A: 100
