Well, you can see in the system that they give you the expression x = 6 - y. So it's literally telling you that, well, x equals (6 - y), and therefore since they're equivalent expressions, you can substitute 6 - y for x to solve the system.
They are using two different functions.
Tell your math teacher that questions like these are loaded and should not be given as assignments.
Answer:
LM = 6
Step-by-step explanation:
use the ratio of corresponding sides
1/3 = 2/LM
LM = 6
Your answer would be 24 marbles. This is because if you add up all the number of pulls, you get 20, which means we would need to multiply all of the results by 3 to see how many pulls you would get in a bag of 60, and so 8 x 3 = 24. I hope this helps,
Answer:
a)
b) The inverse function is a reflection of the original function across the line
y = x. For example, if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x. So you would use it to find the x-value at a y just like you use the original to find the y value at an x.
Step-by-step explanation:
To do an inverse of a function you first switch the independent variable (d) and the dependent variable (c).
d = 0.45c + 5.50
Then you solve for c
d - 5.50 = 0.45 c
c = (d-5.50)/0.45
