Step-by-step explanation:
4x² + 11x - 3 = 0
(4x-1)(x+3) = 0
x = 1/4, -3
Answer: 2b +2f =5----------(1)
3b +4f =8.5---------(2)
From eqn 1
2f = 5 -2b
f = (2.5 - b)
Put f =(2.5-b) in eqn 1
3b + 4(2.5-b) =8.5
3b +9 - 4b =8.5
-b = -0.5
b = $0.5
Step-by-step explanation:
X = -675
I hope this helps! :)
Solve for x, distibutive 0.2:0.2x - 540
Subtract 0.2x to each side: -540 = x - 0.2x
Combine x: -540 = 0.8x
Divide 0.8 to each side: x = -540/0.8 = -675
Answer:
(-3,5) ia the answer
Step-by-step explanation:
It is because when you reflect it across the x axis the first coordinate will be negative and the second number is positive since its in the second square of the graph, so it is more of a resonable guess.
You know that 0 times anything is 0.
So, 0y = 0.
3x + 0 = 3x
Monomial.
