Solve the quadratic equation by completing the square. 2x2 + 3x - 4 = 0

Answers

Answer 1
Answer:

Answer: x = 0

Step-by-step explanation:

4 + 3x - 4= 0

3x=0 (divide both sides by 3)

x= 0/3

x = 0
Answer 2
Answer:

Step-by-step explanation:

2 {x}^(2) + 3x - 4 = 0 \n 16 {x}^(2) + 24x - 32 = 0 \n 16 {x}^(2) + 24x + 9 = 41 \n {(4x)}^(2) + 2 * 4x * 3 + {(3)}^(2) = 41 \n {(4x + 3)}^(2) = 41 \n |4x + 3| = √(41) \n 4x + 3 = + - √(41) \n 4x = - 3 + - √(41) \n x = ( - 3 + - √(41) )/(4)

Answer:

Consider the graph and equation, y = 3x, that represent Alonso’s walking speed. What relationship is represented by this equation and graph? What would the points (3, 9) and (5, 15) represent?

Step-by-step explanation:

What is y=x-4 2x+y=5

Answers

If you would like to solve y = x - 4 and 2 * x + y = 5, you can do this using the following steps:

y = x - 4
2 * x + y = 5
_____________
2 * x + (x - 4) = 5
2 * x + x = 5 + 4
3 * x = 9     /3
x = 9 / 3 
x = 3

y = x - 4 = 3 - 4 = -1

The correct result would be x = 3 and y = -1.
2x + y = 5
-x + y = -4

2x + y = 5
-(2)x + (2)y = (2)5

(x cancels) 3y = 15

y = 5

plug y into one of the two original equations to solve for x:

5 = x - 4

x = 9

The answer is x = 9, y = 5, or (9, 5)

The bug ran from 24 to 78. What distance did it cover? If this run took the bug 9 seconds, what was its average speed?
