If graph of the function y=f(x) was shifted to the right 1 unit, then you got new function y=f(x-1).
Reversly, if you have the function

that is obtained by shifting to the right 1 unit, then the initial function was

.
Answer: Correct choice is D.
Answer:0 and -20
Step-by-step explanation:
5x=0;
x=0/5.
3x+60=0;
3x= -60;
x= -60/3;
x= -20
Answer:


Step-by-step explanation:
Represent trees with T and wreaths with W
Given


Solving (a): Cost of W
Substitute 3 + 4 * W for T in the second equation


Collect Like Terms


Divide through by 6


Hence, each wreath costs $16
Solving (b): Cost of T

Substitute 16 for W



Hence, each tree costs $67
Ok so cos(x) = sin(90-x) so using that you can get sin(7x-15) = sin(90-(3x+5)) so 7x-15 = -3x+85. 10x = 100 and x = 10. Use that to find the 2 angles are 55 and 35
Log4 + logX + log13 = 0
logX = -log13 - log4
logX = -1.716
x= 10^[-1.716]
x= 0.019 A
