Answer:

Step-by-step explanation:

The easiest way is to graph both functions and see where they intersect. The intersection is where f(x) = g(x).

f(x) = -x² - 3x + 6

g(x) = 2x² + 5x + 3

Complete the equation of the line through (6,-6) and (8,8).<br> Use exact numbers.<br> y=?

MariettaO [177]

Y = 7x - 48

use slope formula so, y2 - y1 over x2 - x1 to get your m value or your slope which is 7. then plug in the slope and a random set of point so I used (6, -6). -6 = 6(7) + b, simplify.
-6 = 42 + b, subtract 42 which leaves you with b= -48. hope this helps :)

Ryan has x stamps in his collection if he was 6 times as many stamps as penny, how many stamps does penny have in her collection

Free_Kalibri [48]

The number of stamps with penny in terms of x is $\frac{x}{6}$

<em><u>Solution:</u></em>

Given that,

Ryan has x stamps in his collection

Number of stamps of Ryan = x stamps

Let the stamps with penny be "a"

Ryan has 6 times as many stamps as penny

Therefore,

Number of stamps in Ryan = 6 times as many stamps as penny

$\text{Number of stamps in Ryan } = 6 \times a\\\\x = 6a\\\\a = \frac{x}{6}$

Thus number of stamps with penny in terms of x is $\frac{x}{6}$

Find the height of the tree

NeX [460]

Use the property of similarity of triangles =》the corresponding sides of a triangle should be in the same ratio.

Take the missing side as 'x'.

The corresponding sides here are,

■ 7 & 14 ft

■ 5 & x ft

7/14 = 5/x

7x = 5 × 14 (cross multiplication)

7x = 70

x = 70/7

x = 10 ft

Height of the tree = 10 ft.
