I cannot find the answer on my own, I need a lil' bit of help.
viktelen [127]

for any fraction a/b, the decimal format of it is just a ÷ b.

A)

is the number rational?

well, a rational number is one we can write as a ration or fraction, well clearly is a fraction so it is rational.


B)

can it be written as a repeating/recurring decimal?  well, 9/20 is 0.45, so -9/20 is -0.45, no repeating decimal like 0.454545......... , just a plain vanilla -0.45, so nope.


C)

is it less than -0.4?

well, let's recall that for the negative side on the number line, the closer to 0, the larger the number, so then -1,000,000 is much smaller than -1, because -1 is closer to 0.

who is closer -0.4 or -0.45?

|---------------------  -0.45  --------  -0.40  -------------------  0  ---------------  1  -------------------|

so, -0.45 is farther from 0, and therefore is smaller than -0.4, so yes.

A survey asked people to name their favorite season. The results of the survey showed that 34% said spring and 15% said fall. Wh
max2010maxim [7]

Answer:

D. 29% and 22%

Step-by-step explanation:

The known percentages are 34% and 15%. Add these two together to get 49%. All four choices should add up to 100%. So subtract to find what remains:

100% - 49%

= 51%

We don't actually have enough information to determine the percents for summer and winter. BUT the only answer that adds up to 51% is answer D. 29% and 22%.

Help me with this problem !!!!!!!!!!
Mamont248 [21]

Answer:

Hi, your answer is y=-\frac{1}{2} x-3

Step-by-step explanation:

We will use the slope-intercept formula which is

\frac{y2-y1}{x2-x1}

We will use two points in this case I'll use

(-2,-2) and (-8,1)

\frac{1-(-2)}{-8-(-2)}=-\frac{3}{6} which can be simplified as -\frac{1}{2}

Your Y will be -3

which your final answer will be y=-1/2x-3

Hope this helps :)
