Answer:
Step-by-step explanation:
Since this is a system with two equations, we can easily use a graphing calculator to find the solution
The intersection between the graphs of the equations
y = 3x + 10
2y = 6x – 4 (if we divide by two)
y = 3x - 2
However, we can see that the graphs have the same slope m = 3
Since both equations are not equal, there is no solution for this system
Please see attached graph. The lines are parallel and they never touch each other.
(x, y)=(4,5) hope this helps
Answer:
I think its D? I'm not sure sorry if I get it wrong
Answer:
B) f(x) = 3x² - 2x + 5
Step-by-step explanation:
To find the correct quadratic function that represents the table, you must substitute [x] into the quadratic function.
A) f(x) = 3x² + 2x - 5
B) f(x) = 3x² - 2x + 5
C) f(x) = 2x² + 3x - 5
D) f(x) = 2x² - 2x + 5
A. 3(-2)² + 2(-2) - 5 =
3(4) - 4 - 5
12 - 4 - 5
12 - 9
= 3
B. 3(-2)² - 2(-2) + 5 =
3(4) + 4 + 5
12 + 9
= 21
C. 2(-2)² + 3(-2) -5 =
2(4) - 6 - 5
8 - 11
= - 3
D. 2(-2)² + 2(-2) + 5 =
2(4) - 4 + 5
8 - 4 + 5
8 + 1
= 9
Your correct answer is: B
74.6 - 54.5 = 20.1
20.1/2 = 10.05
54.5/74.6 = 0.731 (rounded)
Apple makes 10.05 billion more every year. The percent growth rate is about 73.1% a year.
