Answer:
$880
Step-by-step explanation:
This is called a system of equations!! Here's how to do it:
1. Make Equations
In this case, the equations would be
- p+c=64 (this is saying that pepperoni pizzas plus cheese pizzas equal 64, which we got from the question.)
- 1/3c=p (this is telling us that he sells 1 pepperonis for 1/3 cheese pizza)
2. Solve the system of equations
For this problem, we will substitute 1/3c for p. The problem becomes
Then you divide by 4/3 to get p by itself:
Now substitute 48 for p in the first equation.
3. Find the money amounts
Now that you know that pepperoni pizzas equal 48, and cheese equals 16, this is easy.
- Multiply 16*10 to get the cheese cost. ($160)
- Multiply 15*48 to get the pepperoni cost ($720)
- Then add those to get the total!
Answer:
The correct option is;
C. (1.6, 1.3)
Step-by-step explanation:
Given that at x = 1.5 the y-values of both equations are y = 1.5 and y = 1 respectively
The x-value > The y-value
The difference in the y-values = 1.5 - 1 = 0.5
At x = 1.6 the y-values of both equations are y = 1.2 and y = 1.4 respectively
The x-value > The y-value
The difference in the y-values = 1.2 - 1.4 = -0.2
At x = 1.7 the y-values of both equations are y = 0.9 and y = 1.8 respectively
The x-value > The first y-value and the x-value < the second y-value
The difference in the y-values = 0.9 - 1.8 = 0.9
Therefore, the approximate y-value can be found by taking the average of both y-values when x = 1.6 where the difference in the y-values is least as follows;
Average y-value at x = 1.6 = (1.2 + 1.4)/2 = 1.3
Therefore, the best approximation of the exact solution is (1.6, 1.3)
By calculation, we have;
-3·x + 6 = 4·x - 5
∴ 7·x = 11
x = 11/7 ≈ 1.57
y = 4 × 11/7 - 5 ≈ 1.29
The solution is (1.57, 1.29)
16.6 feet (with the last 6 repeating) per minute or if you want whole numbers, it would be 50 feet per 3 minute.
The axis of symmetry is x = -5
