A.
It is exponential because the x is listed as an exponent rather than a variable attached to a coefficient.
Answer:
So first u add
-10 + 30
Now you substract
20
Therefore the answer is 20
F(x) = 2x - 10
let y = f(x)
y = 2x - 10 solving for x.
y + 10 = 2x
2x = y + 10
x = (y + 10)/2
Recall f(x) = y. Implies x = f⁻¹(y)
<span>x = (y + 10)/2
</span>
f⁻¹(y) <span>= (y + 10)/2
</span>
So as well:
f⁻¹(x) <span>= (x - 10)/2</span>
Answer:
Simplifying
0.125x + 3 = 10
Reorder the terms:
3 + 0.125x = 10
Solving
3 + 0.125x = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 0.125x = 10 + -3
Combine like terms: 3 + -3 = 0
0 + 0.125x = 10 + -3
0.125x = 10 + -3
Combine like terms: 10 + -3 = 7
0.125x = 7
Divide each side by '0.125'.
x = 56
Simplifying
x = 56
Step-by-step explanation:
Answer: the second option (1/2)
Step-by-step explanation:
numbers greater than 3: 4, 5, and 6
3 numbers
so 3/6 or 1/2
1/2 or 50% so the second option
