Answer:
Step-by-step explanation:
7x - 15 = 4x - 12
3x - 15 = -12
3x = 3
x = 1
y = 7(1) - 15
y = 7 - 15
y = -8
(1, -8)
First we try to frame the equation between the sale price and the final cost.
Let us consider, the price to be x and the final cost to be y, since the final cost is 75% of the price, we have the below equation
y = 0.75x
This is of the form of straight line equation y = mx +c where c =0 and m = 0.75
This means the function is linear since it satisfies a straight line equation.
So, we can eliminate options (3) and (4)
Now, the function is not a continuous one because the function is has definite value which is 0.75x and this make the function discrete. Hence option (2) is eliminated
Therefore we are left with option (1) which is the answer
Answer is (1) It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant
Answer:
Step-by-step explanation:
x² + 9x+8 = (x+1)(x+8)
You know that 3 times 2 is 6 so 30'times 20 equals 60
- The number of vertical pieces will be 28. Then the correct option is A.
- The number of horizontal pieces will be 600. Then the correct option is B.
<h3>What is decision-making?</h3>
The process of making choice is by identifying the correct decision, gathering information, and assessing alternative solutions.
Horizontal pieces can be produced at a rate of 200 per labor hour.
A carpenter uses 500 horizontal pieces and 22 vertical pieces while making racks for an hour.
You have 900 horizontal pieces and 50 vertical pieces in stock right now.
For the next hour, you assign Juan to rack making, Debbie to trim making, and both mike and stan to horizontal piece production.
1. Then at the end of the next hour, the number of vertical pieces available in stock will be
→ 50 - 22
→ 28
Thus, the number of verticle pieces will be 28.
2. Then at the end of the next hour, then the number of horizontal pieces available in stock will be
→ 900 + 200 - 500
→ 600
