Answer:
5r = 7.50
Step-by-step explanation:
As, the cost of 1 ruler = r
So, r times 5 ruler will give u the cost of 5 rulers, which is 7.50
So, 5r = 7.50
F(-2).....this is basically saying that when x = -2, what is y
so f(-2) = 2
because f(x) is the same as y...but when u have f(-2)....this is saying x = -2 and they are wanting to know what y is....and when x = -2, y = 2....so f(-2) = 2
We add 548 and 225 which would be 773
It is a 45-45 - 90 triangle (as the right angle is split in half for the outer one)
In this case, x is in the hypotenuse. The side lengths follow the 1, 1, √2 formula.
If 1 = 3, then:
3 x √2 = Answer
Answer = 3√2
hope this helps
The answer i think is it c
