Basically the inverse is when you reflect the function across the identity line, y=x
basically to find the inverse of a function
flip switch all x and y and solve for y, then replace y with finverse
f(x)=7x-13
y=7x-13
switch
x=7y-13
solve for y
x+13=7y
(x+13)/7=y
finverse=(x+13)/7
3rd one
quantity of x plus 13 over 7
<span>The product of a fraction and 7 is greater than 7, if fraction i a/b then </span>(a/b)*7>7
The denominator 7 means (a/7), so we can rewrite (a/b)*7>7 as
(a/7)*7>7, from this inequality we get
a>7,
so the numerator is greater than 7
Answer:
.7% of the people had a mild allergic reaction
Step-by-step explanation:
42/6000 = .007
To turn the decimal into a percent, you need to move the decimal 2 spaces to the right.
.007 → 00.7 → .7%
