<span>Suppose the equation of the axis of symmetry for a quadratic function is x = 3

and one of the x-intercepts is 8.

What is the other x-intercept?

Recognize that the graph of this function will be symmetric with respect to the axis of symmetry, which is x=3. If one x-intercept is 7, we can quickly calculate that this intercept is 4 units from that axis. The other x-intercept is 4 units from that axis, but in the other direction; therefore, it is x=3-4 = -1.</span>

The points (2,-2) and (-4,13) line on the graph of a linear function of x. Which point also lies on the graph of this function?

Tcecarenko [31]

Answer:

(0, 3) lies on the line joining (2, -2) and (-4, 13).

Step-by-step explanation:

The equation of the line joining the points (2, -2) and (-4, 13) is:

$\frac{y+2}{13+2} =\frac{x-2}{-4-2}$

$\frac{y+2}{15} =\frac{x-2}{-6}$

$\frac{y+2}{5} =\frac{x-2}{-2}$

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

-2y - 4 = 5x - 10

5x + 2y - 6 = 0

When we substitute x = 0 and y = 3,

5(0) + 2(3) = 0 + 6 = 6

So, (0, 3) lies on the line joining (2, -2) and (-4, 13).

Answer:

70 m

Step-by-step explanation:

Perhaps you want to evaluate the expression:

$\dfrac{7\text{ cm}}{1\text{ yr}}\cdot 1000\text{ yr}=7000\text{ cm}=70\text{ m}$

__

There are 100 cm in 1 m. The units of yr cancel.
