f(x) = 3x + 5/x

f(a + 2) = 3.(a + 2) + 5/(a + 2)

Answer:

1/10

Step-by-step explanation:

A number line is a line which contains numbers marked at intervals (usually regular intervals). Points to the right of the origin are positive numbers while those to the left are negative numbers.

The school is used as the origin. Ellie house is 1 and three fifths blocks east (to the right) of the school. This means that it is + 1 and three fifths (+8/5).

Chase house is 1 and one half blocks (3/2) west of Ellie. Since it is west then it is to the left. Hence the coordinate of chase house = 8/5 - 3/2 = 1/10

Hence the coordinate of chase house is 1/10(one tenths).

The error may be as a result of thinking chase house is to the east of Ellie, hence adding to get 3 and one tenth.

Could someone explain why the value of x is (-2).

irina [24]

Answer:

$x=-2$

Step-by-step explanation:

Given equation:

$2x^3+16=0$

To solve for the unknown variable x, apply arithmetic operations to isolate the variable.

Subtract 16 from both sides:

$\implies 2x^3+16-16=0-16$

$\implies 2x^3=-16$

Divide both sides by 2:

$\implies \dfrac{2x^3}{2}=\dfrac{-16}{2}$

$\implies x^3=-8$

Take the cube root of both sides:

$\implies \sqrt[3]{x^3}=\sqrt[3]{-8}$

$\implies x=-2$

When taking the cube root of a negative number, the result will be negative. To understand why, examine what happens when we cube a negative number.

When a number is cubed, it is multiplied by itself, then by itself again.

When multiplying a negative number by another negative number, the result is always positive.

When multiplying a positive number by a negative number, the result is always negative.

Therefore:

$\begin{aligned}\implies (-2)^3 &= -2 \cdot -2 \cdot -2\\ & = 4 \cdot -2\\& = -8\end{aligned}$
