Given number is .
Two-third of the number =
One-third of the number =
The sum of a certain quantity together with two-third of that number, and one-third of that number, becomes 234.
Answer:
-142
Step-by-step explanation:
So we have the function:
To find f(9), substitute x for 9:
Square the first term and multiply the second:
Add:
And that's our answer :)
Answer:
Step-by-step explanation:
The one-to-one functions g and h are defined as follows.
g={(-7,-6), (-5,4), (4,-7)(7,6)}
h(x)= 3x-14
Find the following.
g-1(4)=
"g-1(4)" just says "Find the pair of coordinates that has 4 for its
y-coordinate, and the answer is its x-coordinate". So we look through those
and find (-5,4) is the only one of those up there that has a 4 for it's y-
coordinate, and so its x-coordinate is -5 and we write:
g-1(4)=-5
Use one of the many Trigonometric ratios to solve for the missing angle and then use Pythagorean theorem to solve for the missing side.
These things can be done in any order.
Solve for <span>x</span> by simplifying both sides of the equation, then isolating the variable.<span>x=<span>5</span></span>
