Answer:
Sub the values for x and y into the equations.
Step-by-step explanation:
x = 2
y = 1
Y = 2x - 3
1 = 2(2) - 3
1 = 4 - 3
1 = 1
Y = -½x + 2
1 = -½(2) + 2
1 = - 1 + 2
1 = 1
Answer:
its SAS so yes they're congruent
Step-by-step explanation:
We first need to find f(3).
f(3) = 2(3) + 8
f(3) = 6 + 8
f(3) = 14
We now want g(f(3)).
We know that f(3) is 14.
We also know that g(x) is 5.
As you know, 5 is a constant. No matter what the value of x is for g(x), it will not change the value of g(x).
So, g(f(3)) = g(14) = 5.
Answer: g(f(3)) = 5.
-50 and +50

If two angles are supplementary, then
the sum of their measures is 180°.
So if the measure of an angle is 77°,
the measure of its supplement is 103°.
We can find the measure of its supplement by taking 180 minus the measure of the original angle which in this case is 180 - 77 or 103°.
