Subtract 78.2 from both sides

0.5x+78.2-78.2= 287-78.2

0.5x = 208.8

Divide both sides by 0.5

0.5x/0.5= 208.8/0.5

x= 417.6

I hope that's help !

0.5x + 78.2 = 287
-78.2 -78.2

subtract 78.2 on both sides you will then get 0.5x = 208.8 you will then divide by 0.5 and the answer is x = 417.6

1. Change x = 4t into x = 3t

$4t\cdot\frac{3}{4}=3t$ so

$y=(\frac{3}{4}t)^2-1=\frac{9}{16}t^2-1$

Answer A and D are wrong.

2. Change x = 4t into x = 2t

$4t\cdot\frac{1}{2}=2t$ and

$y=(\frac{1}{2}t)^2-1=\frac{t^2}{4}-1$

Answer b is correct.

3. Change x = 4t into x = 8t

$4t\cdot2=8t$ and

$y=(2t)^2-1=4t^2-1$

Answer C. is correct, E. is wrong.

ASHA 777 [7]

Answer:

1/ 6^12

Step-by-step explanation:

f[x} = x ^ (-2x)

f(6) = 6 ^ (-2*6)

= 6 ^ -12

We know the negative exponent moves it to the denominator

= 1/ 6^12
