Let's call the two numbers x and y. The first sentence, one is 6 less than twice another, translates to

We also know the sum of their squares:

So, we have the following system:

We can use the expression for x in terms of y from the first equation to turn the second equation into something involving y alone:

Expand the square:

Subtract 680 from both sides:

Using the quadratic equation

we find the two solutions

Since we know that both numbers are integer we can only accept the second solution. It yields the following x value:

Answer: f(x) = log(x+1)

Answer:
100 degrees and 70 degrees
Step-by-step explanation:
180 - 10 = 170
with a ratio of 7:10
7x + 10x = 170
17x = 170
x = 170/17
x = 10
one angle in 100 degrees and the other is 70 degrees
