Answer:

255

Step-by-step explanation:

12x^(2) + 39x + 30

x = 3

Substitute in"3" for "x" and solve;

12(3)^(2) + 39(3) + 30

= 12 * 9 + 117 + 30

= 108 + 117 + 30

= 255

D(1) = 8 d(n) = d(n-1) x (-5) what is the 3rd term in the sequence
lisov135 [29]

Answer:

With the rule: d(n) = d(n-1) x (-5), we have:

d(1) = 8

d(2) = d(1)x(-5) = 8x(-5) =-40

d(3) =d(2)x(-5) = -40x-5 =200

Other way:

d(n) = d(n-1) x (-5) => d(n) = d(1)x(-5)^(n-1)

d(3) = d(1)x5^(3-1) =8x5^2=8x25 =200

What is the reflection of image p(0,0) after two reflections first across x=-3 and
pochemuha
<span>P (0, 0) across x = -3 will change the x value. From 0 to -3 which is 3 units down, so the reflection will be another 3 units down ( points are the same distance from the reflection line) so the new x-value is -6 now just do the same thing for the y-value and you will get an image of P¹ ( -6, -6 ) </span>
