Answer:
The Answer is: The first number is 10 and the second number is 8.
Step-by-step explanation:
Let f = first number and s = second number.
The first number is 2 larger than the second:
f = n + 2
The numbers times each other is 80:
f * n = 80
Substitute the value of f, which is (n + 2):
n(n + 2) = 80
n^2 + 2n = 80
n^2 + 2n - 80 = 0
(n + 10)(n - 8) = 0
n^2 + 10n - 8n - 80 = 0, so the first number is 10 and the second one is 8.
Another method, just from thinking about it:
factor 80:
8 * 10, is the first factoring I thought of. I then noted that the difference between the two is 2 and if you multiply them they equal 80.
Hope this helps! Have an Awesome Day!! :-)
Answer:
x=4
Step-by-step explanation:
f(x) = (x-2)^5 +3
Let f(x) = 35
35 = (x-2)^5 +3
Subtract 3 from each side
35-3 = (x-2)^5 +3-3
32 = (x-2)^5
Take the fifth root of each side
32 ^ (1/5) = (x-2)^5^ 1/5
2 = x-2
Add 2 to each side
2 +2 = x-2+2
4 =x
1/2 x 5 equals 2.5
hope that helps lol
X = 9 is the only choice that is not a solution.
Explanation:
7.95, 4.3, and -3 are all values that are less than 8. For instance, if you were to plot these values on a number line, 9 would be the only value to the right of 8 or the only value that surpasses 8.
