The army of a country launches a test rocket from a base. The rocket's height (h) can be determined by the formula h(t) = -1/10t^2 + 30, where t is the time in seconds. From a satellite in space, a laser is fired at the rocket to attempt to destroy it. The laser is fired at the correct time along the line y = -2t + 15. Determine the number of seconds, to the nearest tenth of a second, into the flight that the rocket is destroyed.

y=1/4x-4

step-by-step explanation:

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one

3a-24=0

oh

nu stiu chiar nu stiu sa o fac

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
