B, short explanation remember the sets are set up like (x,y) in a set there should be no matching x points so if it matches it's not a function :)
long explanation: these are (x,y) sets {(0,3), (3,0), (0,4), (4,0)} the first choice shows that there are two X solutions <span>if they are equal to 0 (0,3) (0,4) so this cant be a function.
second choice</span><span> {(0,2), (2,0), (4,6), (6,4)} does not have two X solutions so this is a function
third choice</span>{(2,6), (3,6), (4,6), (2,0)} has two X solutions if x is equal to 2
and the last choice <span>{(6,2), (2,0), (4,6), (6,4)} has two X solutions if x is equal to 6
hope i helped! if i did please give me brainlest :)

Answer:13.1
Step-by-step explanation:
Area equation:S=
Answer:
x<84
Step-by-step explanation:
First, write an inequality. We know it is not an equation because of the words "less than". Also, x and 8 are being added because of the word "and". Here's the inequality: x+8 < 72. Now, subtract 8 on both sides so x is isolated. Our simplified inequality looks like this: x < 84.
Answer:
14 ft
Step-by-step explanation:
Focus on the triangle, and temporarily neglect the 2 ft measurement at the top of the triangle. Then the 2 legs of the triangle have lengths h - 2 ft and 5 ft, and the hypotenuse is 13.
Applying the Pythagorean Theorem, we get:
13^2 = (h - 2)^2 + 5^2, or
169 = h^2 - 4h + 4 + 25, or
144 = h^2 - 4h + 4, or
140 = h^2 - 4h, or, finally,
h^2 - 4h - 140 = 0. We must find the value of h.
I graphed this function on a calculator and found that -10 is a zero. Thus, the function factors into (h + 10)(h - 14) = 0, or h = 14.
The total height of the piece of plywood is 14 ft.
Check this: does a right triangle with legs (14 - 2) and 5 have a hypotenuse of 13? Yes.
Answer:
1176in^2
Step-by-step explanation:
find the surface area of the cube
(14*14)6=1176 inches cubed
14*14 is finding the area of one side and then we multiply it by six because that's how many congruent sides there are
