Answer:
42%
Step-by-step explanation:
1) so out of the 50 girls surveyed, only 21 students played in the league. We can write this as 21/50
to convert this into percentage multiply by 2 on both sides:
21*2=42
50*2=100
42/100=42%
42% of girls played in the league

Hey there!
The distributive property is defined as:
a(b+c) = ab+ac.
Since a is being multiplied by b and c, it's a common factor. In this situation, our common factor is 6, as it goes into 6x and 42. So, we have:
6(7 + x)
Hope this helps!
Y= 5x + 2
For each category you plug it into the equation,
7= (5x1) + 2
12= (5x2) + 2
Answer:
f(x) = f(-x) = x^2 -1 is an <u>even</u> function
Step-by-step explanation:
When f(x) = f(-x), the function is symmetrical about the y-axis. That is the definition of an <em>even</em> function.
___
An odd function is symmetrical about the origin: f(x) = -f(-x).
