Subtitution is the simplest method to find the solution
First, change x to the value of y from the second equation
x - y = 6
x = y + 6
Second, subtitute x with the value of y in the first equation, to find the exact value of y.
x² + y² = 26
(y + 6)² + y² = 26
y² + 12y + 36 + y² = 26
2y² + 12y + 36 - 26 = 0
2y² + 12y + 10 = 0
y² + 6y + 5 = 0
(y + 5)(y + 1) = 0
y = -5 or y = -1
Third, we have 2 values for y. We should find the value of x for each y-value
For y = -5
x = y + 6
x = -5 + 6
x =1
For y = -1
x = y + 6
x = -1 + 6
x = 5
The solution are (1,-5) and (5,-1). The answer is option d
Answer:
108.7 ⇒ nearest tenth
108.67 ⇒ nearest hundredths
108.667 ⇒ nearest thousandths
Step-by-step explanation:
When you divide 652 by 6, you get 108.6666666... (the 6 is repeating)
So, round it to the nearest tenth, hundredths, or thousandths:
108.7 ⇒ nearest tenth
108.67 ⇒ nearest hundredths
108.667 ⇒ nearest thousandths
Answer:
