You would need to know the length of two sides either a2, b2, c2. you would also need to know what sides you are solving for, either one of the legs or hypotenuse. hope this helps, if you know how to solve a Pythagorean theorem problem this should be easy to answer
Hello from MrBillDoesMath!
Answer:
The first choice ( -12, 20)
Discussion:
Using matrix multiplication we find the equations:
1x + 1y = 8 (A)
2x + 3y = 36 (B)
Next, compute
2(A) - B =>
(2x + 2y) - (2x + 3y) = 2*8 - 36 =>
(2x - 2x) + ( 2y-3y) = 16 - 36 =>
-y = -20 =>
y = 20
Substituting this y value in (A) gives
x + 20 = 8 =>
x = 8 - 20 =>
x = -12
The answer is the first choice ( -12, 20)
Thank you,

Answer:
Step-by-step explanation:
Let the equation of the cosine function is,
y = Acos(Bx)
From the graph attached,
A = Amplitude = 
= 1
B = 
B = 
B = 
B = 4
Therefore, equation of the cosine wave given in the graph will be,
y = 1.Cos(4x)
y = Cos(4x)
Answer:
itsw b
Step-by-step explanation:
X was already negative so the only thing turning negative is Y!
So the first one is correct.
They all say the same thing
X ya era negativo, por lo que lo único que se vuelve negativo es Y!
Entonces el primero es correcto
X était déjà négatif donc la seule chose qui devient négative est Y!
Donc le premier est correct
X已经是负数，所以唯一变成负数的就是Y！
所以第一个是正确的
X已經是負數，所以唯一變成負數的就是Y！
所以第一個是正確的
