Use formulas d=rt. find t for r=48.3 m/h and d = 545.79 m. (A) 26,362 h
(B) 497.49 h
(C) 0.09 h
(D) 11.3 h

11.3

Step-by-step explanation:

Just plug in the known variables.

d = rt

d = 545.79

r = 48.3

545.79 = 48.3t

you need to get T alone

so divide

the end answer is 11.3

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
