Answer:

f(-4) = 13

Step-by-step explanation:

Hi there !

f(x) = 0.5x + 15

f(-4) = 0.5×(-4) + 15

= - 2 + 15

= 15 - 2

= 13

Arlecino [84]

Answer:

you need to isolate t or time

you need to know distance between sun and earth and velocity of them in order to calculate how long it takes for light to travel from the Sun to Earth

Step-by-step explanation:

$t*(d)=(v/t)*t\\td= v\\\\\frac{td}{d} =v/d \\t=v/d$

to find time you multiply t to both sides then you cancel t from where velocity is and you get velocity by itself

now you mulipy d to both side to get v over d and time by itself
