Answer:

Yes, the student is correct

Step-by-step explanation:

Given

(0,-10)

Required

Does it represent the x intercept

At the x intercept, the value of x is 0.

So, the function (x,y) becomes (0,y)

(0,-10) can be compared to (0,y)

Hence, the student is correct

Yes, you are correct.

From the image, we can see 3 triangles, the large triangle and the two triangles that make the larger triangle.

All 3 of these triangles are similar since they're angle measurements are the same (can be proven by geometry).

We can gather the following information from the given information.

  • The largest triangle (the one made up of two triangles) has a hypotenuse of 3+9=12, and a leg length of x. The hypotenuse to leg ratio is 12/x
  • The second largest triangle has a hypotenuse length x and leg length 9. The hypotenuse to leg ratio is x/9

We know the hypotenuse to corresponding leg ratio must be equal since these two triangles are similar. Thus, we have the equation:

12/x = x/9

Using the cross product property gives us:

x² = 9 × 12

x² = 108

Taking the square root of both sides gives us:

x = √108

= 6 √3

Thus, your answer is correct. Great job!

Let me know if you need any clarifications, thanks!

Help pls i cant answer and i need to get them right
hoa [83]

The expression has 2 factors, and the second factor has 2 terms.

<h3 /><h3>How many factors has the expression?</h3>

We can write an expression of N factors as:

y = A_1*A_2*...*A_n

Here, the expression is:

4*(8x + 5)

This expression has 2 factors, which are:

4 and (8x + 5)

Now, if we look at the only factor 8x + 5, we have two terms (the terms are the parts that are added), the terms are:

8x and 5.
