Answer:
d. 45
Step-by-step explanation:
You can check the offered answers. You will find that the difference from reversing the digits will only be 9 if the digits differ by 9/9 = 1.
The original number is 45.
__
<em>Check</em>
45 + 9 = 54 . . . with the digits reversed
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
Hi the answer is 117 because 117 times 3 equals 351 , in this type of problems you just have to find a number that when is duplicate is going to give you the answer , so if you add 117 and 117 , 117 , you will find out that your answer is 351.
Answer:
d = 11.401754
For:
(X1, Y1) = (5, 4)
(X2, Y2) = (-4, -3)
Distance Equation Solution:
=√ (-4−5)2+(−3−4)2
=√ (-9)2+(−7)2
=√ 81+49
=√ 130
=11.401754
