Answer:
Just find the coordinate at the point where the x-coordinate is 3
Step-by-step explanation:
F(x) is just another term for Y. The variable of X is the value that you input into the f(x), which just stands for a function. Since the value that they asked for was 3, you know that they inputted the value of 3 as x. Just look where the coordinate at the point where the x-coordinate is 3 to find the answer.
Answer:
B
Step-by-step explanation:
You are making composite functions, since all the answers provided dont fit, I only suggest to clearify that the lone term in the B option, is actually 45x and not 45.
If this is the case, composite functions means that you eval the expresion g(x) in every x variable found in f(x).
Using this, it gives you that f(g(x))= 
Answer:
<u>John spends $ 37.98</u>
Step-by-step explanation:
1. John has a bill of $ 32.57
2. He leaves a tip of 18% on the amount before the coupon or tax is applied, in consequence: 32.57 + 18% (32.57) = 32.57 + 5.86 = 38.43
3. He uses a 10% off coupon on the cost of the meal, therefore:
38.43 - 10% (32.57) = 38.43 - 3.26 = 35.17
4. The tax is 8%, then:
35.17 + 8% (35.17) = 35.17 + 2.81 = 37.98
<u>John spends $ 37.98</u>
Answer:
x ≤ 12.83
(Any number under or equal to 12.8333...)
Step-by-step explanation:
154 ≥ 12x
12.833.... ≥ x
x ≤ 12.83
