Answer:
I graphed it for you in the image below.
Step-by-step explanation:
1\3h-2.7+12=2\3h-6
-2.7+12+6=2\3h-1\3h
15.3=1\3h multiply both sides by 3
45.9=h
Hi. I begin by finding the positive factors of 14. They are: 1 x 14 and 2 x 7. None of those can be added to yield a negative number, so let's now instead consider their negatives: -1 x -14 and -2 x -7. Does either of these pairs, when added, yield -9? Yes: -2 and -7.
To be clear: -2 x -7 = 14; and -2 + -7 = -9.
So the answer is -2 and -7.
Answer:
Value of x for fg(x)=gf(x) at <em>f(x) = 2x²</em> and <em>g(x) = x+1</em> is x = -1/4 .
Step-by-step explanation:
We have, f(x) = 2x² and g(x) = x+1
Now, f(g(x)) = g(f(x))
⇒ <em>2(x+1)² = 2x² + 1</em>
<em>⇒ 2( x² + 2x + 1 ) = 2x² + 1</em>
<em>⇒ 2x² + 4x + 2 = 2x² + 1</em>
<em>⇒ 4x = -1</em>
<em>⇒ </em><em>x = -1/4</em>
