Which function is described by values in the table?

Mathematics

One way to approach this problem is to go ahead and find the actual equation in slope-intercept form.


The slope of the line thru (3,6) and (5,4) is m = (6-4) / (3-5), or -2/2, or -1.

Subbing the known values of m, x and y, we get:

4 = -(5) + b. Then b = 9.

The correct equation (representing the data values in the table) is y = -x + 9.

Use area of squares to visualize Pythagorean theorem
docker41 [41]

We know that the Pythagorean Theorem is a² + b² = c² and that the area of a square is l x w.

Firstly, we'll have to find the two measures of the triangle that correspond to the areas.

Since the figures are squares, we know that the length and width values must be the same.

We could square the numbers to find the side lengths, however we would have to square them again when substituting for the Pythagorean Theorem, so we can leave them as-is and adjust the equation accordingly.

(33) + b² = (44)

Next, we'll subtract our smaller value from our larger.

b² = (11)

Once again, we could find the square root of this number, but we'd just have to square it again to find the area of the square, so we can just simply write our answer as 11 units.

Therefore, the area of the square is 11 units!

<em>Hope this helped! :)</em>

Answer:

m = \frac{7}{3}

Step-by-step explanation:

Given

3m + 8 = 15 ( subtract 8 from both sides )

3m = 7 ( divide both sides by 3 )

m = \frac{7}{3}
