Answer:
I believe 252
Step-by-step explanation:
Answer: 9+3×9×9 = 9+243 = 252 possible 3-digit numbers with at least
2 digits the same.
Answer:
$257.83
Step-by-step explanation:
Subtract like shown below....
310.63 - 52.80 = 257.83
We subtract because we are finding the total amount of money before the deposit.
Hope that helps and have a great day!
Answer: the third option m(x) = - 7x
Justification:
1) For a function to have inverse function, the original function has to be one to one. This is for the original function two (or more) images cannot have different inputs. That condition is satisfied by the function m(x) = - 7x, since it is a straigh line.
2) the function b (x) = x^2 + 3 is a parabola. That means that, except by the vertex, every image is realated with two inputs.
For example, b(x) = 103 => x^2 = 103 - 3 = 100 => x = 10 and x = -10.
3) For the function d(x) = - 9, you cannot tell the input value for the image because it is the same image for any value of x.
4) The function p(x) = |x| also has a pair of images for the same value of x (excpet for the vertex).
For example, for x = - 100 and x = 100, p(x) = 100, so you cannot tell the x value given the p(x) value.
The inverse is the exact opposite so -11, -13 and it if was negative points to plot it would just be possible.
Answer:
The numbers that work are: -15, 5, 3.5, and 4 3/4
Step-by-step explanation:
Subtract 5 from both sides of the equation. Which will give you 15≥3x. Then you divide both sides by 3 which will give you 5≥x.
20≥5+3x
<u>-5 -5</u>
15≥ 3x
<u>÷ 3 ÷ 3</u>
5 ≥ x
