Answer: They second one is rational!
Step-by-step explanation:
A rational number for a decimal is a pattern of numbers.
Answer:
1) Equation's:
2) Number of guest and the charge:
- Cost is same for both at 50 meals. The cost is $1250.
<u>Part 1</u>
Turn sentences into equation's (Let 'y' be total cost and x per meal) :
(i) charges $500 and $15 per meal
(ii) charges $350 and $18 per meal
<u>Part 2</u>
y = y
500 + 15x = 350 + 18x
18x - 15x = 500 - 350
3x = 150
x = 150/3
x = 50
Charge at guest's 50 meal:
y = 500 + 15(50)
y = $1250
Point : (50, 1250)
The figure is a trapeziod
both pairs are parallel
AB slope is 4/3
BC slope is -2/7
AD slope is -2/7
(and I don't know about CD)
Answer:
C. f(x) = 2x + 2 is the answer.
