Answer:
she has a 1/4 of the property remaining
Step-by-step explanation:
Answer:
The second one
Step-by-step explanation:
4x-y=14
4(y+2) -y=14
4y+8-y=14
3y=14-8
3y=6
y=2
x=2+2
x=4
Answer:
(f + g)(x) = 12x² + 16x + 9 ⇒ 3rd answer
Step-by-step explanation:
* Lets explain how to solve the problem
- We can add and subtract two function by adding and subtracting their
like terms
Ex: If f(x) = 2x + 3 and g(x) = 5 - 7x, then
(f + g)(x) = 2x + 3 + 5 - 7x = 8 - 5x
(f - g)(x) = 2x + 3 - (5 - 7x) = 2x + 3 - 5 + 7x = 9x - 2
* Lets solve the problem
∵ f(x) = 12x² + 7x + 2
∵ g(x) = 9x + 7
- To find (f + g)(x) add their like terms
∴ (f + g)(x) = (12x² + 7x + 2) + (9x + 7)
∵ 7x and 9x are like terms
∵ 2 and 7 are like terms
∴ (f + g)(x) = 12x² + (7x + 9x) + (2 + 7)
∴ (f + g)(x) = 12x² + 16x + 9
* (f + g)(x) = 12x² + 16x + 9
I think you didn’t move the negative down with the x, which would require you to divide 6 by -1 which gets you -6
Answer:
y = -2/3x + 8/3
Step-by-step explanation:
3x - 2y + 5? I am assuming you mean 3x - 2y = 5, so this answer is based on this equation.
3x - 2y = 5
-2y = -3x + 5
2y = 3x - 5
y = 3/2x - 5/2
3/2 = -2/3 (This is the perpendicular slope)
(4,0)
y - y1 = m(x - x1)
y - 0 = -2/3(x - 4)
y = -2/3x + 8/3
So the equation would be y = -2/3x + 8/3.
You can check the equations by graphing them:
