the pythagorean theorem is that the two smaller sides is equivalent to the biggest side. (A+B = C)
Answer: 3 1/18
11/3 * 5/6 =
55/18
= 3 1/18

Answer: Choice C</h3><h3>
{ (-2,2), (0,2), (7,2), (11,2) }</h3>
Here we don't have any repeated x values.
In choice A, x = 2 repeats. In other words, x = 2 leads to multiple y outputs. So this is not a function. Choices B and D are similar stories. A function is only possible if every x leads to exactly one y value only. The graph must pass the vertical line test.
Side note: the y values can repeat, but the function won't be one-to-one.
Answer:
(0,3) One solution
Step-by-step explanation:
Step: Solve x+5y=15for x:
x+5y=15
x+5y+−5y=15+−5y(Add -5y to both sides)
x=−5y+15
Step: Substitute −5y+15for x in 7x+2y=6:
7x+2y=6
7(−5y+15)+2y=6
−33y+105=6(Simplify both sides of the equation)
−33y+105+−105=6+−105(Add -105 to both sides)
−33y=−99
−33y
−33
=
−99
−33
(Divide both sides by -33)
y=3
Step: Substitute 3 for y in x=−5y+15:
x=−5y+15
x=(−5)(3)+15
x=0(Simplify both sides of the equation)
Therefore (0,3) which is one solution
