No work free points ;) thx
Answer:
Step-by-step explanation:
F(x)=-x+5
So
f(-4)= -(-4)+5
f(-4)= 4+5
f(-4)= 8
Only we have to substitute value of x then after simplification we will get answer..Hope this will help
Answer:
This table is a guess-and-check, which means that you input whatever number you think might work in this situation in “city gallons”
Step-by-step explanation:
After you just input that same number to wherever the “6” was in the first row...
E.g., if you put “7” for the next “city gallons”, then you’d put “10 - 7 = 3” in “freeway gal” and so on with ever different number you put in for “city gallons”.
That last part in the way bottom goes the same way! Except you input ”c” instead of a number, which is how you find the actual correct answer.
Hope this helps :)
Answer:
Step-by-step explanation:
We can use the rule of three!
We know we have the following relationship:
From here, we can solve this like any other equation:
Therefore, you would earn $28 after washing 4 cars.
Good luck!
First of all, recall that division by zero is undefined; it's nonsensical; it's just not allowed.So zero certainly needs to be excluded when dividing.
But what about multiplying by zero?
The problem is that multiplying by zero can change the truth of an equation:
It can take a false equation to a true equation.
To see this, consider the false equation ‘
2 = 3
Multiplying both sides by zero results in the new equation
2 ⋅ 0 = 3 ⋅0 (that is, ‘0 = 0’), which is true.
