Well... triple the numbers. 7x3 is 21. 1.3x3 is 3.9. And 900,000x3 is 2,700,000.
But the answer is: 3.9gigawatts
It is 729
We get this by doing 3x3x3x3x3x3
You cant solve y but you can form an equation in terms of y
which is y=7-2x
if you were given another equation that has the term y and x than you can solve it.also that is a simultaneous equation.
Hope this helps,dont forget to put this as the brainliest answer if it does to help me out too. xD
Answer:
Step-by-step explanation:
<u>1)</u>
f(x) = -6x + 3
To get the inverse of this, make x be the subject of the formula.
let f(x) = y
6x = 3 - y
x = (3 - y)/6
∴ f(x) = (3 - x)/6
Truly f and g are inverse functions.
<u>2)</u>
f(x) = -3x²+ 5
let f(x) = y
y = -3x² + 5
3x² = 5 - y
x² = (5 - y)/3
x = √[(5 - y)/3]
f(x) = √[(5 - x)/3]
Truly f and g are inverse function.
