Answer:
If Zahara finishes a level in 201 seconds, she earns:
Step-by-step explanation:
To identify the number of points that Zahara obtained when she finished a level in 201 seconds, you must use the given expression:
- -5.5 + 500+ 0.9t + (1 - 1.9t)
Where:
As Zahara took 201 seconds to finish a level, we're gonna replace this value in the equation:
- -5.5 + 500+ 0.9t + (1 - 1.9t)
- -5.5 + 500+ 0.9(<u>201</u>) + (1 - 1.9[<u>201</u>]) (we're not use the unit "seconds", because we don't need it in this calculation)
- -5.5 + 500+ 180.9 + (1 - 381.9)
- -5.5 + 500+ 180.9 - 380.9 (You can organize the numbers is you want)
- 500 + 180.9 - 380.9 - 5.5
- <u>294.5 points</u>
As you can see, <u>Zahara obtains 294.5 points if she finishes the level in 201 seconds</u>.

X B.) it is twice the area of a rectangle of length 4 units and width two units
X C.) it is 1/2 the area of a square of side length 4 units
X D.) it is twice the area of a square of side length 4 units
Answer:
B. y = -x + 2
Step-by-step explanation:
Now, the standard slope formula is y = mx + b, where m is the slope and b is the y intersect. From the graph pictured, we know that it has a slope of 1 since it goes up one point and to the right one point. So, I know the equation of this line is y = x + 2. Now, all that is left is to find this equation with a -x, which indicates that it is a -1 slope. Since option B has the formula y = -x + 2, that is the correct answer.
