Answer:

g(x) > h(x) for x = -1.

For positive values of x, g(x) > h(x).

For negative values of x, g(x) > h(x).

Is the following number rational or irrational? -3+π

enyata [817]

Answer:

B, irrational

Step-by-step explanation:

We know that π is irrational, since it can not be written as a division between natural numbers (a sub class of Real numbers called N), it's value is 3,1415(a whole bunch of decimals after this)

If you remove the decimal part of π by subtracting the integer part of it, that is the number 3. the result will still being and irrational number

Since π= 3(the rational part) +0,1415... (the irrational part)

The resut of π-=3= 0,1415...

inessss [21]

Answer:

6 bags.

Step-by-step explanation:

We have been given that trail mix is sold in 1-pound bags. Mary will buy some trail mix and repackage it so that each of the 15 members of her hiking club gets one 2/5 bag.

Let us find the number of pounds Mary will need to give to 15 members. As Mary wants to give 2/5 of 1 ounce bag of trail mix, so she will need 15 times 2/5 ounces to given to 15 members of her hiking club.

$\text{Pounds of trail mix needed to give to 15 members}=15\times \frac{2}{5}\text{ ounce}$

$\text{Pounds of trail mix needed to give to 15 members}=3\times 2\text{ ounce}$

$\text{Pounds of trail mix needed to give to 15 members}=6\text{ ounces}$

So Mary needs 6 pounds of trail mix to give to 15 members of her hiking club. As trial mix is sold in 1-pound bags, therefore, Mary should buy 6 bags to have enough of trail mix without any trail mix left over.

Alma charges $97 for a job that takes 2 hours and $187 for a job that takes 4 hours. Write an equation in slope-intercept form t

lara [203]

Answer:

y = 45x + 7

Step-by-step explanation:

From the given data, we have ordered pairs (2, 97) and (4, 187). We can use them to find the slope, as such:

$m=\frac{187-97}{4-2}=\frac{90}{2}=45$
