Answer: Choice C) no solution

=============================================================

Explanation:

The first equation says that y and 3x-4 are the same thing.

So we can replace every copy of "y" in the second equation with "3x-4" like so

9x - 3y = 14

9x - 3(3x-4) = 14

9x - 9x + 12 = 14

0x + 12 = 14

0 + 12 = 14

12 = 14

The last equation is false because we get different values on either side. Because the last equation is false, it means the equation 9x-3y = 14 is false when y = 3x-4.

In short, the overall systems of equations is inconsistent and that leads to no solution (choice C).

If you were to graph each equation, you should find that both lines are parallel. Parallel lines never intersect. The solution is the intersection point of any graphed system.

The graphs below have the same shape.what is the equation of the red graph?
Setler [38]

Answer:

G(x)=4-x^{4}

Step-by-step explanation:

Notice that the red graph is the blue graph shifted 1 units up.

According to the function transformation rules, we add k to the output of the function to shift its graph k units up, and we subtract k to the output of the function to shift its graph k units down.

The output of our function is 3-x^{4}, and since we want to shift 1 units up, k=1. In other words, we just need to add 1 to the output of the function:

G(X)=3-x^{4} +1

G(x)=3+1-x^{4}

G(x)=4-x^{4}

We can conclude that the equation of the red graph is G(x)=4-x^{4}.

You decide to make a beanbag in the shape of a sphere with a diameter of 120 millimeters. You will need to find the volume to kn
Damm [24]

Answer:

The volume is 904,320\ mm^{3}

Step-by-step explanation:

we know that

The volume of the sphere is equal to

V=\frac{4}{3}\pi r^{3}

we have

r=120/2=60\ mm ----> the radius is half the diameter

\pi=3.14

substitute the values

V=\frac{4}{3}(3.14)(60)^{3}=904,320\ mm^{3}

What is the length of the hypotenuse in the right triangle shown below?<br>​
Eduardwww [97]

Answer:

C.  6√2.

Step-by-step explanation:

Since this is a right angled isosceles triangle bot legs are 6 units long

So h^2 = 6^2 + 6^2 = 72

h = √72 = 6√2.
