2x^2 +6x -3. if we are using the quadratic equation this would be

- 6

+ or -

\sqrt{{6}^{2} - 4 \times 2 \times ( - 3) }

all over 2×2

this simplifies to

x =  -  \frac{3}{2}  +  \frac{ \sqrt{15} }{2}

and

x =  -  \frac{3}{2}   -   \frac{ \sqrt{15} }{2}

If the points at (-4, 3) and (2, 3) are reflected over the x-axis to create two new points, what shape can be formed by the four
Svetllana [295]

Answer:

Step-by-step explanation:

Let (a,b)\in \mathbb{R}^{2}, a reflection over the x-axis consists in the following operation:

(a,b) \rightarrow (a,-b)

If we know that X = (-4,3) and Y = (2, 3), then the points translated over the x-axis are X' = (-4, -3) and Y' = (2,-3), respectively. The most precise description of the shape is a rectangle for the following facts:

1) XX' = YY' = 8 and XY = X'Y' = 6.

2) X and X' have the same x-component.

3) Y and Y' have the same x-component.

4) X and Y have the same y-component.

5) X' and Y' have the same y-component.

A representation of the shape is included below as attachment.

Barry wanted to save at least $700. He opened a savings account with an initial deposit of $150. After his initial deposit, Barr
uysha [10]

at least 700

he has already 150

he depositis the same amount for one year to attain his goal of 700

so we assume he attains his goal

150+depositintheyear is at least his goal

150+deposit≥700

deposit=deposit total in the year=

amount per month times number of months=x times 12=12x


the inequality would be 150+12x≥700

Answer:

  L'(4, -3)

Step-by-step explanation:

The reflection over the horizontal line y=-1 effects the transformation ...

  (x, y) ⇒ (x, -2-y)

So, the coordinates of L are transformed to ..

  L(4, 1) ⇒ L'(4, -2-1) = L'(4, -3)
