Answer: Here are a few ways that you could apply expressions or equations to a camping trip.
The cost of renting a cabin could be: C = 50N + 70, where C is the cost and N is the number of nights.
The number of tents needed could be: T = P/3, where T is the number of tents and P is the number of people going.
The amount of marshmallows needed could be: M = 5P, where M is the number of marshmallows and P is the number of people.
For 1 the equation of the parabola is y = x^2 - 8x + 3
For 2 the equation of the parabola is y = -2x^2 - 3x + 1
For 3 the equation of the parabola is y = -x^2 + 5x - 4
Answer:
<h2>only x = 39</h2>
Step-by-step explanation:
x + 6 = 45 <em>subtract 6 from both sides</em>
x + 6 - 6 = 45 - 6
x = 39
ANSWER: The size of a red blood cell IS approximately half the size of a plant cell.
EXPLANATION:
<em>1. We divide the size of the plant cell by 2 to see if half of its size is the size of a red blood cell. </em>
![\frac{0.00001265}{2} = 0.000006325 m](https://tex.z-dn.net/?f=%5Cfrac%7B0.00001265%7D%7B2%7D%20%3D%200.000006325%20m)
Therefore, half of a plant cell's size is 0.000006325 m.
<em>2. We now compare the size of half of the plant cell to the size of the red blood cell.</em>
0.000006325 m and 0.000007 m are very close in size; therefore, the size of a red blood cell IS approximately half of a plant cell.
(-3,4) is CORRECT!!!!!!!!!!!!!!!!
