The graph of y = 4x2 - 4x – 1 is shown.
11Alexandr11 [23.1K]

Answer:

i) The approximate solutions are: x_{1} \approx -0.207, x_{2} \approx 1.207.

ii) The approximate solutions are: x_{1}\approx -0.5, x_{2} \approx 1.5.

Step-by-step explanation:

i) The best approach to estimate graphically the solution of 4\cdot x^{2} - 4\cdot x - 1 = 0 is graphing the following system of equations:

y = 4\cdot x^{2}-4\cdot x - 1 (1)

y = 0 (2)

And labeling the points in which both intersects each other. We include the result in the image 'solution-i'. The approximate solutions are: x_{1} \approx -0.207, x_{2} \approx 1.207.

ii) The best approach to estimate graphically the solution of 4\cdot x^{2} - 4\cdot x - 1 = 2 is graphing the following system of equations:

y = 4\cdot x^{2}-4\cdot x - 1 (1)

y = 2 (2)

And labeling the points in which both intersects each other. We include the result in the image 'solution-ii'. The approximate solutions are: x_{1}\approx -0.5, x_{2} \approx 1.5.

(2,-1)<br> Is one of many solutions to the inequality:<br> X - 3y&lt;1<br> True or false?
aksik [14]

Answer:

False

Step-by-step explanation:

lets find out..

x - 3y < 1.....check (2,-1)....x = 2 and y = -1

now we sub

2 - 3(-1) < 1

2 + 3 < 1

5 < 1.......so is 5 less then 1 ? NO, it is not...so (2,-1) IS NOT a solution

Error Analysis A classmate found the slope of the line passing through (8,-2) and (8.10), as shown at the right. Describe your c
GarryVolchara [31]

Answer:

m=undefined; 12/0

Step-by-step explanation:

The classmate's mistake is that she should have placed the y and top and the x on the bottom.

m= 10+2/8-8

m= 12/0

The slope is undefined, meaning that it is a vertical line.
