Answer:
X = 18
y = 9
Step-by-step explanation:
Basically the 2 diagnols bisect each other making them congruent. so that makes
x-3 = 15 and y + 3 = 12
simplify and
the. you simplify and get x = 18 and y =9
Answer:
(1, -6)
Step-by-step explanation:
the layout of your question is kind of confusing, but i'm guessing this is the system of equations
x = -y - 5
-3x + 7y = -45
plug in x to the second equation
-3(-y - 5) + 7y = -45
distribute
3y + 15 + 7y = -45
combine like terms
10y = - 60
divide by 10
y = -6
plug y into first equation
x = -(-6) - 5
x = 6 - 5
x = 1
Answer:
7g+3h
Step-by-step explanation:
you combine like terms by adding 3g and 4g and subtracting 2h from 5h.
A(5) = 2 + 5^2 = 2 + 25 = 27
Step-by-step explanation:
This sequence is defined as a(n) = 2 + n^2.
Thus, a(1) = 2 + 1^2 = 2 + 1 = 3
Then a(5) = 2 + 5^2 = 2 + 25 = 27
