Answer:
let me explain how you do this:
Step-by-step explanation:
first, you write your equation down:
-x + 5y = 8
next, group everything out seperately so you can know what to do in this problem, like grouping out each variable and number you see. then, figure out if the solution is simplified down to the last number. if so, if there is two variables that aren't the same, try and figure out a way to solve this equation with these two different variables. figure out if you have to multiply, subtract, add, or divide.
To start off, you should make each fraction have a common denominator.
2*3 = 6
3*2 = 6
The lowest common denominator is six.
so 3 3/6 + 2 2/6 = 5 5/6
Hopefully that helps!
Answer:
y = - 3
Step-by-step explanation:
Locate x = 2 on the x- axis, then go down vertically until the line is met.
Then read the corresponding y- coordinate at this point.
When x = 2 the value of the function is y = - 3
Answer: -5
Step-by-step explanation:
The appropriate exponential function for the first question is
... A: f(n) = 10 × 1.2^n
To find the revenue from sales of that many glasses, we multiply by the sale price to get
... B: 0.5(10 × 1.2^n)
