Answer:

-1/2

Step-by-step explanation:

use the slope formula:

(2-4)/(2-(-2)) = -2/4 = -1/2

you can also look at the graph and see it rises -2 (negative means goes DOWN 2) and runs 4, and the slope is rise/run, so it would be -2/4 which simplifies to -1/2

Answer:

The slope is negative one half.

Step-by-step explanation:

Slope is defined as rise over run, or Δx/Δy, when going left to right. In this case, the line goes from (-2,4) to (2,2), so the slope is:

$\frac{2-4}{2 - (-2)} \\\frac{-2}{4}\\= \frac{-1}{2}$

Change to decimals. 1. 75%

ANEK [815]

Answer: 0.75

Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.

So we can think of 75% as the ratio 75 to 100 or 75 ÷ 100.

Dividing by 100 moves the decimal point two places to the left so 75 ÷ 100 will move the decimal point two places to the left which would give us .75 or 0.75.

This means that 75% can be written as the decimal 0.75.

Evaluate 33/5 - 1/10

azamat

Answer:

$\large\boxed{\dfrac{13}{2}=6\dfrac{1}{2}=6.5}$

Step-by-step explanation:

We have the different denominators.

The common denominator is 10.

$\dfrac{33}{5}=\dfrac{33\cdot2}{5\cdot2}=\dfrac{66}{10}$

We can subtract these fractions now.

$\dfrac{33}{5}-\dfrac{1}{10}=\dfrac{66}{10}-\dfrac{1}{10}=\dfrac{66-1}{10}=\dfrac{65:5}{10:5}=\dfrac{13}{2}\\\\\dfrac{13}{2}=\dfrac{12+1}{2}=6\dfrac{1}{2}$
