A) The cost in dollars is given as 50 + 0.50x, so ...
f(x) = 0.50x +50
B) You want to find x for f(x) = 100. Substitute the given numbers and solve for x.
100 = 0.50x +50
50 = 0.50x
50/0.50 = x
100 = x
You drove 100 miles during the week if the cost was $100.
<span>Let f represent the cost of ordering each ticket online. Write an equation that could be used to find the cost of ordering each ticket online. Each ticket is 24.95 each, you ordered 2 tickets and the total is 64.50</span>
Answer: y=-1/3x+5
Step-by-step explanation: I presume they want this in the y=mx+b format where m is the slope (change in y/change in x) of the line and b is the y-intercept (what y is when x is equal to 0). To answer this you need to choose any 2 points on this graph. For simplicity's sake, I'm going to choose (0,5) and (9,2). What's good about choosing (0,5) is that we now know the y-intercept is 5. Now, to find slope, subtract the y coordinate 2 from the y coordinate 5. You now know that the change in y is 3. Then, subtract the x coordinate 9 from the x coordinate 0. You now know that the change in y is -9. Finally, divide 3 (change in y) by -9 (change in x) and you should get -3/9 which can be simplified into -1/3. So now that you have your y-intercept and your slope, all that's left to do in plug it into the format. So your answer should be y=-1/3x+5. Hope this helps you!
Answer:
Area of the shaded region = Area of large circle - Area of small one!
So your answer = 125.1 cm^2
Step-by-step explanation:
Area of large circle = piR^2
= 3.14 * 11 * 11
= 379.4 cm^2
Area of the small circle = piR^2
= 3.14 * 9 * 9
= 254.34 cm^2
Area of the shaded region - (379.4 - 254.34)cm^2
= 125.1 cm^2
Answer:
