Maria is on a hike. If she hikes to the scenic lookout on the following map first, she will have to hike farther than if she
iren [92.7K]

Based on the distance to the end of the hike and the distance to the scenic lookout, we can calculate that the straight route is 2 km shorter than the scenic lookout route.

<h3>Which route is shorter for Maria?</h3>

If Maria took the straight route to the end of the Hike from the coordinates, (4, -4) to (-5, 5), she would have to walk 13 km.

If she went the scenic lookout route, she would have to first go to (2,3) before going to (-5,5) which is 15 km.

The difference is:

= 15 - 13

= 2 km

A more readable version of the question is:
Maria is on a hike. If she hikes to the scenic lookout on the following map first, she will have to hike farther than if she went straight to the end of the hike.

3 connected points on a coordinate plane. The point labeled, "Maria," is at 4, -4. The point labeled, "end," is at -5, 5.

A solid line connect the points "Maria" and "end." The point labeled, "scenic lookout," is at 2, 3. Dashed lines connect "Maria" to "scenic lookout" and connect "scenic lookout" to "end."

An increased the quantities of all the ingredients in a recipe by 60, percent. She used 80 grams left parenthesis, right parenth
iogann1982 [59]

Answer:

The recipe did require 50 grams of cheese.

Step-by-step explanation:

Since, 60 percent extra cheese is used, therefore the given amount of cheese is 160% of recipe requirement. Or in other words, the given amount of cheese is 1.6 times the requirement.

80 grams = (1.6)(Recipe Requirement)

Recipe Requirement = 80/1.6 grams

<u>Recipe Requirement = 50 grams</u>

For the function , f(x) = 2x + 1. If f(x) = 3 , what is the value of x?
kodGreya [7K]

Answer:

For functions, the two notations mean the exact same thing, but "f (x)" gives you more flexibility and more information. You used to say "y = 2x + 3; solve for y when x = –1". Now you say "f (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one").
