2 = 2????

Thats what Im getting it from.

Since x is 2 then it would still be 2=2 in simple term.

Which equation could generate the curve in the graph below?

dimulka [17.4K]

Answer:

The answer is option 1.

Step-by-step explanation:

In order to find the equation, you have to apply Discriminant Law, D = b² - 4ac. When D < 0, the equation has no real roots (no x-intercept). When D = 0, it has 2 and equal roots (1 x-intercept). When D > 0, it has 2 distinct roots (2 x-intercept).

Option 1,

$y = 3 {x}^{2} - 2x + 1$

$D = {( - 2)}^{2} - 4(3)(1)$

$D = - 8$

$D < 0$

Option 2,

$y = 3 {x}^{2} - 6x + 3$

$D = {( - 6)}^{2} - 4(3)(3)$

$D = 0$

Option 3,

$y = 3 {x}^{2} - 7x + 1$

$D = {( - 7)}^{2} - 4(3)(1)$

$D = 37$

$D > 0$

Option 4,

$y = 3 {x}^{2} - 4x - 2$

$D = {( - 4)}^{2} - 4(3)( - 2)$

$D = 40$

$D > 0$

As you look at the graph, the curve does not meet x-axis so the discriminant must be less than 0.

Luiza delivers newspapers in her neighborhood. If you plot the points (−1, 1), (4, 1), (4, −2) and (−1, −2), you will create a r

wel

The first thing to do in this case is to draw the ordered pairs in the Cartesian plane and join the points.
We have then that the resulting figure is a rectangle.
We must find the perimeter of the rectangle that is given by:
P = 2L + 2W
Where,
L: long
W: width
Restoring the values:
P = 2 * (5) + 2 * (3)
P = 16
Answer:
her route cover 16 miles.
