The point (-3, -5) is on the graph of a function. Which equation must be true regarding the function?
Scrat [10]

Answer:

f(-3)=-5

The problem:

(-3,-5) on the graph of f implies which of the choices:

A) f(-3)=-5

B) f(-3,-5)=-8

C) f(-5)=-3

D) f(-5,-3)=-2

Step-by-step explanation:

If the name of the function is f and (-3,-5) is on the graph of f, then you can conclude the value y=-5 corresponds to x=-3.

In other words, the value f(x) is -5 when x=-3.

f(x)=-5 when x=-3 just means f(-3)=-5.

In short, (a,b) on f means that f(a)=b.

The width of a rectangle is 15 ft. shorter than its length. Its perimeter is 262 ft. Let l equal the length of the rectangle.
masha68 [24]
Let the length be l.
For now, let's make the width be w. 
Additionally, l = w + 15. Using this equation, width can also be written as l - 15. 
The perimeter of a rectangle is length + length + width + width. This can also be written as l + l + (l-15) + (l-15) = l + l + l - 15 + l - 15 = 4l - 30.
Using this equation:
4l - 30 = 262
4l = 292
l = 73

4(w + 15) - 30 = 262
4w + 60 - 30 = 262
4w + 30 = 262
4w = 232
w = 58
