How are the real solutions of a quadratic equation related to the graph of the quadratic function?

The solutions you get when you solve the formula are the corresponding y coordinates to your x value. So say a point on your graph is (2,3). The first number is x and the second is y. (x,y). The number you plug into your function is x,or in this case: 2. The solution to the equation when the x value is plugged in is y, or 3. Therefore, giving you a point on your graph.

Alexxandr [17]

Answer:

The gas-only SUV will exceed the cost of the hybrid after 37,111.2 miles.

Step-by-step explanation:

0.18×37,111.2=6680.016

27,055+6680.016=<u>33,735.016</u>

33,735.016≥33,735

A college is currently accepting students that are both in-state and out-of-state. They plan to accept three times as many in-st
kodGreya [7K]

Answer:

0

Step-by-step explanation:

Given:

Maximum number of out-of-state students, x=100

Maximum number of in-state students, y=3x

Therefore, the range of out-of-state students can be anywhere between a number greater than 0 but less than or equal to 100 as this is maximum limit.

0

In order to get the interval for y, we multiply the above by 3 throughout.

3\times 0< 3\times x\leq 3\times 100\\0 < 3x\leq 300

But 3x = y. Therefore,

0< y\leq 300

what is the equation of the line that is parallto the given line and passes through the point (2,3)?​
UNO [17]

Step-by-step explanation:

Here's how you can solve it if you have the equation of the line. Parallel lines have the same slope but different y-intercepts, meaning that if the equation of the line is in standard form, y = mx + b, then the m's are the same but the b's are different. To find the equation plug in the point (2,3) into whatever the original equation of the line is, (for demonstration purposes I am going to use m = 2 and b = 1). So....

3 = 2(2) + 1

But instead of solving it and proving it is true, take out the 1 and solve. (If you were to try to solve for it with the original b it would prove to be a false statement.)

So you actually have this equation.

3 = 2(2) + b

Now solve for b and plug that into the new equation. In this case, using the numbers I made up the parallel line would have the equation of y = 2x - 1.
