Answer:

The answer to your question is

Step-by-step explanation:

Data

                   4x - 8y = -16    ------------ (I)

                     x - 2y = - 8     ------------ (II)

a) Solve equation II for x

                     x = 2y - 8

   Substitute x in equation I

                    4(2y - 8) - 8y = -16

                    8y - 32 - 8y = -16

                     8y - 8y = 32 - 16

                            0 = 16             The system has no solution because y was

                                                     cancelled.

b) When a system of equations do not have solution means that the lines are parallels and different.

What is the surface area of the right prism below ?
topjm [15]

Answer:

Step-by-step explanation:

First find the area of the 2 bases, the triangles. 6x8= 48\2= 24 + 24= 48

Now find the area of each rectangle, which there are three of them. 8x14= 112, 6x14= 84, 10x14= 140

Now add all rectangles and triangles together 48+ 112+ 84+ 140= 384

Which statements describe the graph of y = 3√x-1+2 ? Check all that apply.
Reptile [31]

Answer:

The correct options are A, D and E.

Step-by-step explanation:

We are given the function y=\sqrt[3]{x-1} +2

From the graph below, we see that,

Domain and range of the function is the set of all real numbers.

<em>As y-intercept is the point where the graph of the function crosses y-axis.</em>

That is, y-intercept is obtained when x= 0.

So, on substituting, we have,

y=\sqrt[3]{0-1} +2

i.e. y=-1+2

i.e. y= 1

Thus, the y-intercept is (0,1).

<em>Also, x-intercept is the point where the graph of the function crosses x-axis.</em>

That is, x-intercept is obtained when y= 0.

So, on substituting, we have,

0=\sqrt[3]{x-1} +2

i.e. -2=\sqrt[3]{x-1}

i.e. -8=x-1

i.e. x= -7

Thus, the x-intercept is (-7,0).

Hence, the correct options for the function are,

A. The graph has a domain of all real numbers.

D. The graph has a y-intercept at (0, 1)

E. The graph has an x-intercept at (–7, 0).
