Answer:
f(x) = x - 3
Step-by-step explanation:
y = mx + b
first let's find b, the y-intercept
based on the graph, the y-intercept is (0,-3), so b = -3
immediately, we can eliminate f(x) = 3 - x and f(x) = -3x
comment any questions pls
Answer:
The value of f(30) is equal to 2.
Step-by-step explanation:
The given expression is :

We need to find the value of f(30)
Put x = 30 in above expression.
So,

Hence, the value of f(30) is equal to 2.
Answer:
x=12.50
y = 17.50
Step-by-step explanation:
x = Amount of one Derek withdrawal
then amount of John withdrawal =x+5
Total withdrawals of Derek = no of times x one time withdrawal
= 7(x) = 7x ... i
No of John withdrawal = no of times x one time withdrawal
= 5(x+5) ... ii
Given that i and ii are equal
i.e. 7x =5(x+5)
7x = 5x+25
2x =25
x = 12.50 dollars
Y = 17.50 dollars
Checking part:
total derek withdrawal = 7(12.5) =87.50
Joh's withdrawal = 5(17.50) = 87.50
Since both are equal, our answers are right.
Solution: Derek withdrew each time 12.50 dollars each for 7 times and John withdrew 17.50 dollars each for 5 times.
