Step-by-step explanation:
Given
Solving (a): Number of students
Represent students with S and non students with N
So:
--- (1)
--- (2)
Make N the subject of formula in (1)
Substitute 434 - S for N in (2)

Divide through by -2
<em>Hence; 286 students attended</em>
Solving (b):
Recall that
<em>148 non students attended</em>
The answer is d, ive had this question before and thats what i put
For #2 an easier way to solve problems like this is to move the decimal point to the left twice in this case it’ll be 0.15 instead of 15% now you multiply 35 by 0.15 which is 5.25 now you add the total price and the tip 35+5.25=40.25 and there’s your answer
Answer:
g(x) = Negative two-fifths(10)x
Step-by-step explanation:
In order to reflect a function over the x-axis, you have to multiply the function by minus one.
Given the function:
f(x) = 2/5(10)^x
Its reflection over the x-axis is:
-f(x) = -2/5(10)^x = g(x)
