Based on its degree, what kind of polynomial is this? h(x)=4x^4+2x-5

To estimate the degree of a polynomial, you just have to take a look at the highest power in the expression. Since here, that is number 4, then it means that this polynomial is a fourth degree polynomial, or quartic polynomial, if you want to sound smart. :)

Graph the solution set of this inequality: 5x − 4y > 20.

Yanka [14]

Answer:

Step-by-step explanation:

Solve the inequality 5x − 4y > 20 for y, as follows: Subtract 5x from both sides, obtaining:

-4y > 20 - 5x;

Then divide all terms by -4:

y < -5 +(5/4)x, where the direction of the inequality sign has been reversed because of division by a negative quantity.

Temporarily replace the < symbol with = obtaining y = -5 +(5/4)x. Now choose at least three x values and find the corresponding y values. For example:

x y = -5 +(5/4)x

0 -5

4 0

-8 -15

Now plot these three points (0, -5), (4, 0) and (-8, -15). Draw a dashed line through them. Because of the < symbol in y < -5 +(5/4)x, shade the area underneath the dashed line.

F(x)=3.7-2x

Luda [366]

Answer:

C) h(x)=-1.3-1.75x

Step-by-step explanation:

f(x)=3.7-2x

g(x) = 0.25x-5

f(x) + g(x) =3.7-2x + 0.25x-5

Combine like terms

= -1.75x - 1.3
