Answer:
18% intrest
Step-by-step explanation:
Answering pretty sure yes
the price per book is $3 the constant of proportionality is 3
12 divided by 4 is 3 and 9 divided by 3 is 3 so it means that the price for 1 book is going to be 3 and for every book you buy the original value will be 3.
67°
Angles on a straight line add to 180, so:
A + D = 180
D = 180 - A
D = 180 - 113
D = 67
f(x) = 4x² - 1
The given function is; f(x) = x²
Now, when stretched vertically by a factor of 4, we have;
f(x) = 4x²
It's now shifted 1 unit down.. Thus, the final function will be;
