Step-by-step explanation:

1) a) 3 - 4*5² = 3 - 4 * 25

= 3 - 100

= -97

$b) 2 + \frac{10}{5}*4 = 2 + 2*4 \\\\ = 2 + 8\\\\= 10$

c) (2 -8)² - 2*(-3) = (-6)² - 2*(-3)

= 36 - 2*(-3)

= 36 + 6

= 42

Step-by-step explanation:

If you rearrange the equation in b, you get

y=5(x-3)+15

This means that your f(1) is equal to f(3), or 15, and for each additional month, it increases by 5, which is what the table shows.

Find the midpoint of the segment with the following endpoints.<br> (4,2) and (7,6)

Tema [17]

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(4,2) and (7,6)

The midpoint is

$M = ( \frac{4 + 7}{2} \: , \: \frac{2 + 6}{2} ) \\ = ( \frac{11}{2} \: , \: \frac{8}{2} )$

We have the final answer as

$( \frac{11}{2} \: , \: 4)$

Hope this helps you
