Answer:
x=1, z=-2, y=3
Step-by-step explanation:
Substitution Method
Answer:
y = 5
Step-by-step explanation:
y = mx + b
5 = 6m + b
5 = 3m + b
Take the first minus twice the second.
-5 = - b
b = 5
Substitute back to calculate m.
5 = 6m + 5
6m = 0
m = 0
No, It's not.
coefficients for perfect square would be:
3² - 2(3)(6) + 6² = 9 - 36 + 36
Answer:
5.3
Step-by-step explanation:
Use Pyth Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 8^2
36 + b^2 = 64
b^2 = 28
Sq root of 28 = 5.3
