The answer is $29.99. First, you add $10 to $49.98 which equals 59.98. Next, set up a proportion: x over 59.98 equals 50 over 100. 59.98 times 50 equals 2,999. Now divide 2,999 by 100 and you get your answer.
The parent function for quadratic equations is as followed:

where a for vertical stretches, b is for horizontal stretches, h is the x value of the vertex, and k is the y value of the vertex.
The vertex of the is (-3, -2), so we can write the first part of the equation:

To determine if the graph has any stretches, we can check how changes to the x coordinate affect the y value. If there are no stretches, as the x coordinate moves away from the vertex, the y coordinate should be x^2 from the vertex. If we test with a couple points on the graph, wee see that this is true, so there are no stretches. The answer is:
Answer:
D=160-13 1/3t
Step-by-step explanation:
D is distance in this instance
We are using y=mx+b for this.
The initial distance is 160 miles, that's our y-intercept or <em>b</em><em>.</em>
Now we need to find our slope. If Andrew is 40 miles away in 3 hours, he is 13 and 1/3 miles away in 1 hour. It's negative because you are subtracting from the initial distance. You can keep that as an improper fraction if that makes it easier for you.
Now plug it in
Distance=13 1/3 miles times <em>how</em><em> </em><em>many</em><em> </em><em>hours</em><em> </em>subtracted from 160 or D=-13 1/3+160. This can be rearranged to the answer above.
The Answer is 2.21 Meters Of Wood, Because 2.25+3.12= 5.37 He needs 7.58 Meters In All, so Subtract.
7.58-5.37=2.21 Meters. that is the amount of wood he still needs. Hopefully its not to difficult for you.
