Answer:
D
Step-by-step explanation:
3,280
the decimal moves across four places so you get...
0.328 x 10^4
<span>3x2(7x2 − 9)
Multiply 3x^2 by 7x^2 and -9(Use distributive property)
Final Answer: D.) 21x^4 - 27x^2</span>
Y intercept occurs when x = 0
so its 0-4 / 0- 4 = 1
coordinates of y intercept is (0,1)
x intercept occurs when y = 0
(x -4) / (x^2-4) = 0
x-4 = 0
x = 4
x intercept at (4,0)
I was originally going to graph the two equations, but I don't have graph paper so I set the equations equal to each other.
so Mr.Reeds equation is: y=70x+4.5 and Mrs.Reeds equation is: y=85x
so if I set these equal to each other I would minus the 70x from both sides leaving me with 15x = 4.5. Now since that's done I would divide everything by 15 which will cause me to get a fraction. So once that's done I would be left with x=3/10. I hope this helped!
