Answer: y = 7
Explanation:
7^8/7y = 7^6
7^7/y = 7^6
In order for 7^7 to become 7^6 you need to divide by 7
Which mean y = 7
So that:
7^7/7= 7^6
7^6 = 7^6
Answer:
80 questions
Step-by-step explanation:
- 35/100 = 28/x
- 35x = 28(100)
- 35x = 2800
- x = 2800/35
- x = 80
Answer:
y=3/5x+3
Step-by-step explanation:
The y-intercept which is the (+3) is taken from where the line crosses the y-axis.
The slop is found from rise over run, in this case, -5 to 0 is positive 5 this would go in the denominator, because we go from solid ground 0 to 3 without crossing another solid point, the numerator is 3.
It follows from the definition of the binomial coefficient:
So we have
That is, 
gets absorbed into the numerator's factorial, and we introduct 
into the denominator. Now, 
, so we get
as required.
