Answer:

Yes.

Step-by-step explanation:

$f\left(x\right)=-3x+2$

$f\left(-1\right)=-3(-1)+2$

$y=f(-1)=5$

The domain of this function is all Real numbers $\:\left(-\infty \:,\:\infty \:\right)$

$\{x \in \mathbb{R}: -\infty \:$

Hank the hiker would like to go on a hike. He only has four hours available today for the hike. The expression 1/2d + 1/2e is us

alisha [4.7K]

Answer:

No. Hank wont be able to complete the hike.

Step-by-step explanation:

Time Available for hike = 4 hours

The expression which represents the time Hank needs to complete the hike is:

$\text{time}=\frac{1}{2}d+\frac{1}{2}e$

d is the distance in miles of the hiking trail. Since, Hank would like to hike 6 miles, d = 6

e is the elevation gain in thousands. Since, the trail hank will hike on has an elevation gain of 3000, so e = 3

Using these values in the expression, we get:

$\text{Time}=\frac{1}{2}(6)+\frac{1}{2}(3)=4.5$

This means Hank should allow him 4.5 hours or the hike. Since he has only 4 hours available, he wont be able to complete the hike. So the answer to this question is No.

It is not 82 accidentally clicked it

Hi!

Your answer is 52.

To start off, let's start with some facts that will help us solve this:

Supplementary angles are two angles whose angle measures add up to 180 degrees. You can know that they are supplementary because they can be connected by a straight line.

Triangles (all of them) have angles that add up to 180 degrees.

We can start by using supplementary angles to solve. See where the angle of 67 degrees is? The one to the right of it is supplementary to it since they are on a straight line. That means their sum adds up to 180 degrees:

$67 +?=180$

$?=113$

That angle is 113 degrees.

Now, we have 2 out of 3 angles in the triangle. Since we know that triangles' angles add up to 180 degrees, we can make an equation:

$15+113+x=180$

$128+x=180$

$x=52$

Therefore, x is equal to 52.

If she chooses the 8-inch tiles, she will need a quarter as many tiles as she would with 2-inch tiles.

denis23 [38]

In the above word problem, If she chooses the 8-inch tiles, she will need a quarter as many tiles as she would with 2-inch tiles, Quarter 8-inch tiles will cover the same area as one 2-inches.

<h3>What is the justification for the above?</h3>

Note that the area of the one 2-inch tiles is given as:

A1 = 4in²

The area of the quarter 8-inch tiles is:

A2 = 1/4 x 8 x 8

A2 = 16inch²

Divide both areas

A2/A1= 16/4

= 4

This implies she'll need four 2-inch tiles to cover the same amount of space as a quarter 8-inch tile.
