1 -4
2 -10
3 10
4 -21
and you will need to figure the rest out
Answer:
b and c
Step-by-step explanation:
because they are correct
Answer:
The answer to your question is because it is a solution of each equation.
Step-by-step explanation:
Data
Point (3,4)
Equation l y = 1/3x + 3
Equation ll y = 2x - 2
Process
1.- To test is a point is solution to a system of equations,
-Substitute the point in both equations
Equation l 4 = 1/3(3) + 3
4 = 1 + 3
4 = 4 The point is a solution because
4 = 4
Equation ll 4 = 2(3) - 2
4 = 6 - 2
4 = 4 This point is a solution for the second
equation but not for the first one.
2.- Conclusion
As the point is a solution of each equation, it is a solution of the system.
Answer:
x = 2.2
Step-by-step explanation:
Comment
f(x) = g(x) I don't think has any meaning for this question. I will just solve the equation.
Solution
7x - 12 = - 3x + 10 Add 3x to both sides
7x + 3x -12 = - 3x + 3x +10 Combine
10x - 12 = 10 Add 12 to both sides
10x -12 + 12 = 10 + 12 Combine
10x = 22 Divide by 10
10x/10 = 22/10
x = 2.2
Answer:
f is not defined at x = 3 ⇒ answer (b)
Step-by-step explanation:
∵ f(x) = x² - x - 6/x² - 9 is a rational function
∴ It will be undefined at the values of x of the denominator
∵ The denominator is x² - 9
∵ x² - 9 = 0 ⇒ x² = 9 ⇒ x = ±√9
∴ x = ± 3
∴ f(x) can not be defined at x = 3
∴ The f(x) can not be continuous at x = 3
∴ The answer is (b)
