I will give you the points so that you can draw the graph
x y
(number of chairs assempled in 20 days) (number of tables assembled in 20 days)
0 5
4 4
8 3
12 2
16 1
20 0
Then the graph of the function y = 5 - x/4 will pass for all those points. It will intersect the y-axis at 5 and the x-axis at 20. Note that this mean tha if she makes 0 chairs she will make 5 tables, and if she makes 20 chairs she will make 0 chairs.
The function y = 5 - 4/x is continuos, but the real function of assembly is discrete, because she cannot assemble a fraction of chairs or a fraction of tables.
Answer:
The solutions are 3 and -3
Explanation:
To get the solution, we will need to isolate the x on one side of the equation as follows:
10x² - 56 = 88 - 6x²
10x² - 56 + 56 = 88 - 6x² + 56
10x² = 144 - 6x²
10x² + 6x² = 144 - 6x² + 6x²
16x² = 144
x² = 144/16
x² = 9
x = <span>±</span>√9
either x = +√9 = 3
or x = -√9 = -3
Hope this helps :)
The solution for h is ⇒ A
Step-by-step explanation:
Let us revise how to solve an equations contains many letters for one letter
- Write the equation and under line the letter you want to solve the equation for it
- Separate this letter one side and put the other letters in the other side
- Divide the two sides by the coefficient of the letter
∵ m = 8k + 5h
- We need to solve it for h, then take 8k to the other side with m
by subtracting 8k from both sides
∴ m - 8k = 5h
- Divide both sides by the coefficient of h
∵ The coefficient of h is 5
∴ Divide both sides by 5
∴
- Switch the two sides
∴
The solution for h is

Answer:
The net change is - $0.30
Step-by-step explanation:
3.5 - 3.7 = -.2
-.2 + 3.3 = 3.1
3.1 - 3.4 = -.3
