B. 5 is the input
Step-by-step explanation:
f(x) = 4x + 3 f(5) = 23 Plug in 5 for x.
f(x) = 4(5) + 3
f(x) = 20 + 3
f(x) = 23
B. 5 is the input
Answer:
Yes, both have the same value ( 20) when x = 5.
Step-by-step explanation:
We have two functions:
y = 15 + x
y = 4*x
We want to see if these functions have the same value when x = 5.
Then we just need to replace x by 5 in both equations, and see if the values of y are the same
first function:
y = 15 + 5 = 20
second function:
y = 4*5 = 20
So yes, both functions are equal to 20 when x = 5.

The answer is "Option A".
Step-by-step explanation:
Dormitory students.
Please find the complete question in the attched file.
indicates that teachers live in the west hall.
indicates that the students live in the south tower.
describes the likelihood which West Hall students received free coupons.
indicates that students in the south tower were given free coupons.
To maximize the probability that the person selected at random will receive the coupon, multiply the following numbers by the possibility of success of the coupon:
Ali is correct because you shouldn’t deliver the minus in the 5b number
Answer: x < 0
There is no underline under the "less than" sign
===================================================
How I got this answer:
We have an open hole at 0, and shading to the left. The shading represents all the possible solutions. For example, x = -1 is a solution since it is in the blue shaded region. We can list out the numbers -7, -6, -5, -4, -3, -2, -1 as values in the solution set, but we'd be working forever since there are infinitely many numbers in this set. Also, we'd be excluding fractional and decimal values using this slow method.
As a shortcut, we can just say "any number less than 0 is a solution" which we write as x < 0 or "x is less than zero". We do <u>not</u> include x = 0 itself due to the open hole at 0 on the number line.
