Since she had $35.48 on her card.
Amount spent in buying coffee = $70 - $35.48 = $34.52
Cost of coffee = $8.63 per pound
No of pounds = Amount spent / cost per pound
= 34.52 / 8.63 Use your calculator.
= 4
The speed at which they are moving apart = 475 + 525 = 1000 mi/h
Time = distance / speed
= 6000 / 1000 = 6 hours
The answer is 6 hours.
F (9)= 5(9) -16
45-16
f(9)=29
Answer:
We can graph y = 2x/3 - 2 to find the line.
We know one point, which is the y-intercept. The y-intercept is (0,-2) so that is our first point. Plot that point on the chart. Now to find another point, we can just insert a number for x and solve for y. I am going to use the number 3.
y = 2x/3 - 2
y = 2(3)/3 - 2
y = 6/3 - 2
y = 2 - 2
y = 0
So when x = 3 y = 0. We have another point,which is (3,0) Plot the points (0, -2) (3, 0) and draw a line between the points and that is your graph.
there ya go
