Help pls? Thank you :)

it's the last one

Step-by-step explanation:

just look up "reciprocal" lol

this is just a definition

A fraction that is the multiplicative inverse of the given fraction

Step-by-step explanation:

Let's prove the possible answers wrong:

A fraction with 1 as a denominator could be 5/1.  But a fraction could also have a 1 in the numerator, like 1/5. 5/1 and 1/5 are reciprocals

A fraction whose numerator and denominator have the same value. That means the only number possible is 1, when it is 1/1. But 5/1 can be a reciprocal as well

A fraction with the numerator as 1. Wrong, it can be 5/1 as well.

The last one is correct because is a reciprocal is when the numerator and the denominator is switched, or multiplicatively inverted.

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

-Chetan K

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
