Answer: Choice B
Range = {-3, 1, 5}
============================================
Explanation:
The domain is the set of all possible input x values. The range is the set of all possible y outputs.
Plug in each x value from the domain, one at a time, to get its corresponding range y value.
--------------------
Start with x = -3
f(x) = 2x+3
f(-3) = 2(-3)+3
f(-3) = -6+3
f(-3) = -3
So -3 is in the range.
--------------------
Move onto x = -1
f(x) = 2x+3
f(-1) = 2(-1)+3
f(-1) = -2+3
f(-1) = 1
1 is also in the range
--------------------
Finally plug in x = 1
f(x) = 2x+3
f(1) = 2(1)+3
f(1) = 2+3
f(1) = 5
The value 5 is the final value in the range.
--------------------
All of those values form the set {-3, 1, 5} which is the complete range.
Answer:
x=4.5
Step-by-step explanation:
Given the equation , we simplify as:
#We further simplify as multiples of 9(divide by 9 to solve for x):
Hence, from our simplification the equation has the same value as x=4.5

I think the answer is 30x+330>50x
Step-by-step explanation:
for the option A it was slightly changed,
cause the $30 was deposited by <em><u>helen</u></em> not <em><u>Vince.</u></em>
<em><u>so </u></em><em><u>check </u></em><em><u>that </u></em><em><u>well</u></em>
