The price y is a function of x, the speed of the processor.

In function notation this means, y=f(x), where f(x)=<span>101x + 207.85.
</span>
For example to calculate the (approximate) price of a laptop with processor 4 gigahertz, we let x=4, and plug in f. 

That is the price y for x=4 is calculated by y=f(4).

So, since y=f(x)=<span>101x + 207.85, the (expected) price of a laptop with processor speed 2.5 gigahertz is :

y=f(2.5)=101(2.5)+207.85= 460.35 ($)


Answer:

</span>C. $460

Answer: the top box can be the linear equation y=40x+15 and the bottom box is 40

Step-by-step explanation:

If you swim 15 more minutes than your friend and your swam 55 minutes, that means your friend only swam 40 minutes. The set amount of time that your friend swims for <em>x</em> is 40 minutes. So the additional time you swim is <em>b</em>, 15 minutes.

Answer:

58 units squared

Step-by-step explanation:

We want to find the area of the square. To do so, we need to find the hypotenuse of the right triangle because this coincides with the side length of the square.

We use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:

a^2 + b^2 = c^2

Here, a = 7 and b = 3, so:

7^2 + 3^2 = c^2

c^2 = 49 + 9 = 58

Now, the area of a square is: A = s^2, where s is the side length. Well, c is the side length, and we've already found what c^2 is (it's 58), so that means the area of the square is 58 units squared.

Thus, the answer is 58 units squared.

The difference between number 20 and its opposite is what percentage of 200? (if you do not remember: opposite of 15 is −15; opp
True [87]
20%

This is because 20 and it's opposite -20 is 40. (20 - -20 = 40). Then 40 is 20% of 200.
