PLEASE HELP!!!
Anuta_ua [19.1K]

Answer:

The value of g(-1) is -2

Step-by-step explanation:

g(x) = 2x^4 + 3x^3 - x^2

Now we find g(-1)

To find g(-1) plug in -1 for x  in the given g(x) equation

Replace all x by -1

g(x) = 2x^4 + 3x^3 - x^2

g(x) = 2(-1)^4 + 3(-1)^3 - (-1)^2

g(x) = 2-3-1=-2

The value of g(-1) is -2

I will mark you brainliest!!!! Which ordered pair is the best approximation of the solution?
Ulleksa [173]

Answer:

D

Step-by-step explanation:

We can substitute y = 2x + 1 in the second equation

2x + 1 = -7x + 8

Add 7x to both sides

9x + 1 = 8

Subtact 1 from both sides

9x = 7

x = 7/9

Substituing x in the first equation

y = 14/9 + 1

x rounds to 0.8

y rounds to 2.5

What are the solutions to the equation (x – 2)(x + 5) = 0?
nataly862011 [7]

A product of two (or more) factor can be zero if and only if at least one of the factors is zero.

In other words, you cannot multiply two non-zero real numbers, and have zero as a result.

So, if we want the product of these two factors to be zero, at least one of them has to be zero.

The first factor is zero if

x-2 = 0 \iff x=2

The second factor is zero if

x+5 = 0 \iff x=-5
