Answer:
um i think its i dont know
Step-by-step explanation:
sorry but i dont know this
Y=mx+b where m=slope which is change in y divided by change in x m=(-8-7)/(4-9)=-15/-5=3 so we have y=3x+b now we can use either point, I'll use (9,7), to solve for b or the y-intercept... 7=3(9)+b 7=27+b b=-20so our line is: y=3x-20
Answer:
557.28

Answer:
x=-1
Step-by-step explanation:
3/x - 5 = 10/x +2
add 5 to each side
3/x = 10/x +7
subtract 10/x from each side
-7/x = 7
multiply by x on each side
-7 = 7x
divide by 7
-7/7 = x
-1=x
