Keep in mind both the distance and time of the scenarios. The faster and more distance travelled = a higher gradient for the line. If he slows, the gradient decreases. If he stops, the line is flat but time still goes on.

Use the remainder theorem to find the remainder of 2x^4 + x^2 - 10x -1 divided by x +2.

I am Lyosha [343]

Answer:

The remainder is 55

Step-by-step explanation:

Let

$p(x)= 2 {x}^{4} + {x}^{2} - 10x - 1$

According to the remainder theorem, if p(x) is divided by x+a, the remainder is p (-a).

The given divisor is x+2, therefore the remainder is given by:

$p( - 2)$

We substitute x=-2 to get:

$p( - 2)= 2 {( - 2)}^{4} + {( - 2)}^{2} - 10( - 2) - 1$

We simplify to obtain:

$p( - 2)= 2 \times 16 + 4 + 20- 1$

We multiply to get:

$p( - 2)=3 2 + 4 + 20- 1 = 55$

Therefore the remainder is 55

Round fraction 3 3/2 to nearest whole number

fenix001 [56]

The answer is: 4 because when you put the mixed number in an improper fraction it is 11/3 and 11 divided by 3= 3.67, so you will need to round it to the nearest whole number which is 4

Answer:

The correct answer is: Option D) 5

Step-by-step explanation:

Given equation is:

$3(x + 2) + x = 2x + 16$

In order to find that which values of x makes the equation true, we have to put each value of x in the equation. When both sides of equations will be equal, that value of x will be true for the equation.

Putting x = 2

$3(2 + 2) + 2 = 2(2) + 16\\3(4)+2 = 4+16\\12+2 = 20\\14 \neq 20$
