Question 1 of 10<br> What is the x-intercept of the function graphed below?
aleksley [76]

The "x-interept" is the point where the graph crosses the x-axis.

From here, it looks like this graph crosses the x-axis where x=2 .

So the point is  <em>(2, 0)</em> .

That's choice-<em>A</em> .

Brainliest Answer!!!

Its fairly straightforward. Since the bottom equation only has one unknown,x, because y=1.3, you can plug y in and solve for x. Once you find the value of x, you then have the value for two variables, x and y, and again have one unknown coefficient a. To solve for the coefficient you just plug in your y value (1.3) and your x value (which can be rounded to 0.42). Using a little bit of algebra, you can then solve for a which should be a=2.108. I am not sure if your teacher wants you to solve it this way but you could also use the elimination method or substitution method that you would of learned when discussing system of equations. But no matter which way you do it, the math follows the rules. Hope this helps. I’d suggest you solve it yourself to double check my work.

Hey there, Selenawebb0418!

If you look at the table, you can see that the plant grows 2 centimeters (I'm assuming it's centimeters) every 3 days.
So, the rate of the plant should be \frac{2}{3} cm per day.

Thank you for using Brainly.
See you soon!
