Answer:

Step-by-step explanation:

First, we plug in -3 in place of x...

f(x) = 2(-3)^2 + (-3) + 1

Then, we simplify each indidvidual expression...

f(x) = 18 - 3 + 1

Finally, we add/subtract all the values to get our answer...

f(x) = 16

using the midpoint formula, solve for the midpoint of the segment with these pairs of endpoints (20,-15) and (-11,-10)

Gre4nikov [31]

Answer:

(9/2, -25/2)

Step-by-step explanation:

The Midpoint Formula: The midpoint of the segment joining points $(x_1,\,y_1)$ and $(x_2,\,y_2)$ is $\left(\frac{x_1+x_2}{2},\,\frac{y_1+y_2}{2}\right)$ .

$\left(\frac{20+(-11)}{2},\,\frac{-15+(-10)}{2}\right)$

$(\frac{9}{2},\,-\frac{25}{2})$

By the way, instead of trying to memorize the formula, why not just think the x-coordinate of the midpoint is the average of the x-coordinates of the points. The y-coordinate of the midpoint is the average of the y-coordinates of the points.

The average of two numbers is exactly halfway between them!

Convert the following repeating decimal to a fraction in simplest form .53

galben [10]

9514 1404 393

Answer:

53/99

Step-by-step explanation:

When an n-digit repeat begins at the decimal point, the repeating digits can be placed over an equal number of 9s to make a fraction. Sometimes, that fraction can be reduced to lower terms.

$0.\overline{53}=\boxed{\dfrac{53}{99}}$
