Find the midpoint of the line segment joining the points (10,7) and (negative 2,negative 7).

Basile [38]

The midpoint of the line segment joining the points (10,7) and (negative 2,negative 7) is (4, 0)

<h3><u>Solution:</u></h3>

Given that line segment joining the points (10,7) and (negative 2, negative 7)

Thus the two points are (10, 7) and (-2, -7)

The midpoint of two points $(x_1, y_1)$ and $(x_2, y_2)$ is given as:

$M(x, y)=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)$

$\text {Here } x_{1}=10 \text { and } y_{1}=7 \text { and } x_{2}=-2 \text { and } y_{2}=-7$

Substituting the values in formula, we get

$\begin{array}{l}{M(x, y)=\left(\frac{10+(-2)}{2}, \frac{7+(-7)}{2}\right)} \\\\ {M(x, y)=\left(\frac{10-2}{2}, \frac{7-7}{2}\right)} \\\\ {M(x, y)=(4,0)}\end{array}$

Thus the midpoint of line segment is (4, 0)

Consider f(x) = 4x^3 – 5, g(x) = 2x + 5 and h(x) =2x^2+2x. Which statement about (f + g – h) is true?

Natalka [10]

$\large{\mathcal{ANSWER:}}$

b) It is a cubic function of 4 terms.

In this case p(3) = t + 2 is synonymous for p = 3 + 2. Remember p is synonymous for y. So in this equation it is p = 5.

Hope this helps!
