4 0

Answer:

Step-by-step explanation:

y=ar^x

(ar^5)/(ar^3)=72/432

r^2=1/6

Since r^2 < 1

This is exponential decay.

7. Write an equation for the line that is parallel to the given line and that passes through the given point.
Vlad1618 [11]

Answer:

C. y = 1/2x - 14

Step-by-step explanation:

Find the slope of the original line and use the point-slope formula  y − y 1 = m ( x − x 1 )  to find the line parallel to  y = 1 /2 x − 8 .

y = 1 /2 x − 14                              PARALLEL

...................................................................................................................................................

Find the negative reciprocal of the slope of the original line and use the point-slope formula  y − y 1 = m ( x − x 1 )  to find the line perpendicular to  y = 1 /2 x − 8 .

y = − 2 x − 29                               PERPENDICULAR

Which Graph correctly solves the equation below? -1/2x^2 +2 = 2x^2 -8
lubasha [3.4K]

Answer:

see attachment

Step-by-step explanation:

The given equation is

-  \frac{1}{2}  {x}^{2}  + 2 = 2 {x}^{2}  - 8

The graph of the left hand side of this equation is

y =  -  \frac{1}{2}{x}^{2}  + 2

This quadratic graph has its vertex at (0,2) and turns upside down.

The right hand side of the equation is

y = 2 {x}^{2}  - 8

This quadratic graph opens upwards and has its vertex at (0,-8).

The two graphs intersects at two points , which are (-2,0) and (2,0).
