Answer:

4x^11+x^7+3x^3-5x+9

Its highest to lower based on the exponential number

our exponential numbers are: 3, 1, 7,0,11 putting those from highest to lowers would put them: 4x^11+x^7+3x^3-5x+9

Select the correct inequality for the graph given
Kaylis [27]

Answer:

y<= 3x-1

Step-by-step explanation:

When it comes about inequalities, keep in mind the following

the < sign means that the regions is under whatever is to other side, and the > means that the region is above whatever is on the other side of the sign

So, we see for the graphic that there is a region below a line, this suggests us that there is a < sign implied

The other thing is that there is a convention in math, is the line is graphed using a dashed line, it meas that it is not part of the region, if the line is graphed using a solid line (a continued line) then the line is inside the region, hence there is a = sign implied.

So the answer is y<= 3x-1

Solve for the value of v.
DanielleElmas [232]

Answer:

V=14

Step-by-step explanation:

Well its a supplementary angle if you add everything together.

We know theres a 90 degrees angle and a 34 degree angle.

90+34=124

124+4v=180

Since if you add everything up its a straight line

Solve the equation normally

56=4v

14=v
