Answer:
11
Step-by-step explanation:
1st plug in the given numbers for each variable (the letters)
4 x 6 ÷ 3 + 3 =
Next, use the order of operations to solve the expression.
4 x 6 ÷ 3 + 3 =
24 ÷ 3 + 3 =
8 + 3 = 11
Equation would be: 25.15 - 1.75x
Where, x = number of days.
Substitute for x = 3,
= 25.15 - 1.75(3)
= 25.15 - 5.25
= 19.90
In short, Your Answer would be $19.90
Hope this helps!
Answer:
Range: (-∞, 0]
General Formulas and Concepts:
<u>Algebra I</u>
- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
When we graph the equation, we should see that our y-values span from -∞ to 0. Since 0 is a closed dot, it is inclusive in the range:
(-∞, 0] or y ≤ 0
Lets Sean's age be x
Helen's age by y
x/y=3/5
x=3/5y
Second equation
2(x-2)=y-2
on solving u get Helen as 10 and Sean as 6
It really does not matter ... anyone can be a many-to-one function !!
