Answer:
Hi there!
Your answer is:
h(5y) = 5y-9
Step-by-step explanation:
h(5y) means we substitute 5y for p! This completely gets rid of the p!
Hope this helps
Answer:
<u>8. and anything less</u>
Step-by-step explanation:
The line thing would be pointing to the left as 8 and lower fit the solutions.
8 - 4 = 4 which is less than 5
7 - 4 = 3 which is less than 5
6 - 4 = 2 which is less than 5
If you were to carry on testing these where <em>X</em> is getting smaller in value, it will never end. Any number above 8 will not work
<span>Let's use the quadratic formula:
2w² -</span><span><span> 20w </span>+ 50 = 0</span>
a = 2 b = -20 c = 50
x = -b +-sq root(b^2 - 4*a*c) / 2*a
x = --20 +-sq root(400 -4*2*50) / 4
x = 20 +-sq root(400 -4*2*50) / 4
x = 20 +-sq root( 0) / 4
x = 20 / 4 =5
I'd say it has one rational solution.
It does NOT have 2 solutions because the "plus / minus" section = 0.
