Answer:

(- 2, 3)

Step-by-step explanation:

The solution of the graphed system is the point of intersection of the 2 lines.

This occurs in the second quadrant where the x- coordinate is negative and the y- coordinate positive.

A reasonable estimate is therefore (- 2, 3)

Please help!! I need the answer to the question in the picture!!!!

Answer:

$\large\boxed{D.\ x=-2(y+3)^2-1}$

Step-by-step explanation:

The equation of a horizontal parabola in the standard form:

$x=a(y-k)^2+h$

(h, k) - vertex

if a > 0, then open right

if a < 0, then open left

We have the vertrex (-1, -3) and the parabola is open left (a < 0).

Therefore the equation of a given parabola could be:

$x=-2(y-(-3))^2+(-1)=-2(y+3)^2-1$

Add. Write your answer in scientific notation. (8×106)+(7.92×109)

Anettt [7]

The sum of the numbers 8 × 10⁶ and 7.92 × 10⁹ in the form of scientific notation will be 7.928 × 10⁹.

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The expression is given below.

8 × 10⁶ and 7.92 × 10⁹

The addition of both terms 8 × 10⁶ and 7.92 × 10⁹ will be

⇒ 8 × 10⁶ + 7.92 × 10⁹

⇒ 8 × 10⁶ + 7920 × 10⁶

⇒ 7928 × 10⁶

⇒ 7.928 × 10⁹

The sum of the numbers 8 × 10⁶ and 7.92 × 10⁹ in the form of scientific notation will be 7.928 × 10⁹.
