An easy this to do is use desmos... an online graphing site that will allow you to graph the curves and points... 

https://www.desmos.com/calculator

The alternate method is to subsitute each point into each equations... 

I just did (-2, 2) into A... that point is not on the curve.. that would be the hard way. Subsituting x = -2  y = 18 so (-2, 2) isn't on the curve. 

so eliminate A

repeat the process with B etc   is (-2, 2) in on the curve, then select the next point and check. 

That's why graphing is easier

The average movie ticket price in dollars since 1980 can be modeled by 0.142x + 1.93 where x is the number of years since 1980.
ipn [44]

Answer:

Step-by-step explanation:

1985:

x = 5 years  ( 1980 to 1985- 5 years)

0.142x + 1.93 = 0.142*5 + 1.93

                     = 0.71 + 1.93

                     = $ 2.64

                     

1999:

x = 19 years

0.142x + 1.93 = 0.142*19+ 1.93

                     = 2.698 + 1.93

                     =4.628 =  $ 4.63

                     

2010:

x = 30 years

0.142x + 1.93 = 0.142*30 + 1.93

                     =  4.26 + 1.93

                     = $ 6.19

Which is the slope for the equation that is perpendicular to y=-4x+3
zzz [600]

Answer:

\frac{1}{4}

Step-by-step explanation:

The equation for a line is y=mx + b where m represents the slope

If a line is perpendicular to another line, it's slope is the negative reciprocal of the other line's slope.

The reciprocal of -4 is -\frac{1}{4}

And the negative of that would be \frac{1}{4}

Mashutka [201]

33/4 is the same as 8 1/4

so that means that matt bought the Volvo for 8 1/4 times as much as the car his parents bought.

therefore... 8,000 times 8.25 = 66,000
