Answer:
a = 7 + 2b/5 + 3c/5
b=−35/2 + 5a/2 − 3c/2
c = −35/3 + 5a/3 − 2b/3
Step-by-step explanation:
Yes
Answer:
a= 3/4
Step-by-step explanation:
2/3 x 3/4- 1/6 = 1/3
Answer:
undefined slope, it's a vertical line
Begin by following the herd . . . call the two numbers 'x' and 'y' .
You said that xy=1 , so y = 1/x
You said that x + y = 10, so x + 1/x = 10
Multiply each side by 'x': x² + 1 = 10x
Subtract 10x from each side: x² - 10x + 1 = 0
Use the quadratic formula to solve this, and the two solutions
that you get for 'x' are also the two numbers 'x' and 'y' .
They are
<em>9.89898</em>
and
<em>0.10102</em>
