You would take the 3/4 in buttons and measure them all up, width, lenth, sides. I'm not sure if its lxwxh but if it is, go for it! hope i helped!

Solve the system.
emmasim [6.3K]

Answer:

x = 2

y = -1

Step-by-step explanation:

2x + y = 3

-2y = 14 - 6x

6x - 2y = 14

2x + y = 3 | ×3 |

6x - 2y = 14 | ×1 |

6x + 3y = 9

6x - 2y = 14

__________--

5y = -5

y = -5/5

y = -1

2x + y = 3

2x + (-1) = 3

2x = 3 + 1

2x = 4

x = 4/2

x = 2

For which equation will f(-2)= -6?
Mila [183]

Answer:

C. f(x)=4x^3+6x^2-x

Step-by-step explanation:

Lets plug in -2 into each of these equation to see which one gives us the solution of -6

A. f(x)=x^3+x

f(-2)=(-2)^3+(-2)\\\\f(-2)=-8-2\\\\f(-2)=-10

B. f(x)=x^4-5x

f(-2)=(-2)^4-5(-2)\\\\f(-2)=16+10\\\\f(-2)=26

C. f(x)=4x^3+6x^2-x

f(-2)=4(-2)^3+6(-2)^2-(-2) \\\\f(-2)=4(-8)+6(4)+2\\\\f(-2)=-32+24+2\\\\f(-2)=-6

D. f(x)=-3x^3-4x^2+4x

f(-2)=-3(-2)^3-4(-2)^2+4(-2)\\\\f(-2)=-3(-8)-4(4)-8\\\\f(-2)=24-16-8\\\\f(-2)=0

As we can see, function C was the only one that gave us the value of -6, so that is our answer.

A piecewise function g(x) is represented by the graph.
stira [4]

For different function different results are shown below.

<h3>What is Function?</h3>

A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B.

We have been given a graph of piecewise function. Using that we have to select the function from given choices which is represented by graph.

g(x) = −2x, −2 < x < 0

Answer:

NO. Because g(x) = −2x has negative slope so that means it goes downward also there is no y-intercept in g(x) = −2x but the only graph that has y-intercept in given graph goes upward so that can't be answer.

g(x) = −2, x < −2

Answer:

YES. Because g(x) = −2 is a horizontal line which is only on the left side of x=-2. Graph of this part is present in given graph. So yes it is answer.

g(x) = x − 2, −2 < x < 1

Answer:

NO. Because g(x) = x−2 has y-intercept at y=-2 and slope 1 so that means graph of g(x)= x-2 must be going upward and crossing at y=-2 but there is no such graph. Hence this can't be answer.

g(x) = −2x + 6, x ≥ 1

Answer:

YES. Because g(x) = −2x+6 satisfies the graph which is going downward.

g(x) = x/2+ 1, –2 ≤ x < 1

Answer:

YES. Because g(x) = x/2+ 1 satisfies the graph which is going downward.
