Answer:
Then the desired equation is y = -2x - 6.
Step-by-step explanation:
As we move from point (-3, 0) to point (0, -6), x increases by 3 and y decreases by 6. Thus, the slope of the line segment connecting these two points is m = rise / run = -6/3 = -2.
Now use the slope-intercept equation of a straight line to determine the y-intercept of this line:
y = mx + b becomes 0 = -2(-3) + b, so that b = -6.
Then the desired equation is y = -2x - 6.
Check: Does (0, -6) satisfy y = -2x - 6? Is -6 = -2(0) - 6 true? YES

Answer:
$500
Step-by-step explanation:
You hand him 100%
He pays back 140%(original amount plus 40%)= 700
Original amount =x
700/140 = x/100
140x=700*100
140x = 70,000
x=500
200 is the 40% of 500
500+200= 700
Answer:
3 seconds
Step-by-step explanation:
Maximum height=150
150=-16t^2+96t+6
-16t^2+96t-144=0
-16(t^2-6t+9)=0
-16(t-3)^2=0
t=3 seconds
