Answer:
Step-by-step explanation:
let f(x)=y
y=2x+5
flip x and y
x=2y+5
2y=x-5
y=(x-5)/2
f^{_1}(x)=(x-5)/2
but f^{-1}(x)=1
so (x-5)/2=1
x-5=2
x=2+5=7
Here's the steps (if you know how just do this equation as if it was a literal equation)
Answer:
C.5, Because when you you add the line of best fit on the graph it goes through the 5 point right over 4 wins won last year.
Answer:
It means that 20 times x is 5
also the answer to that problem (20x=5) is 1/4
Step-by-step explanation:
20x means
20 * x
and since 20 * x = 5
divide 5 and 20
5/20 = 1/4
First, assign a variable that you're looking for.
Let x = the larger number
Then x - 1 = the smaller number
The sum of x and x - 2 will equal to 226.
x + x - 1 = 226
2x - 1 = 226
2x = 228
x = 114
So, the smaller number is 112 and the larger number is 114.
