-x^2 = 4
(-x)(-x) = 4
x^2 = 4
x = 2

So, 2 is the answer.

If y varies inversely with x and y = 8...<br><br> the question is in the picture
pshichka [43]

Answer:

I believe the answer is 4.

Step-by-step explanation:

Since y = 8 when x = 4, y is double or 2 times x. So, when x = 2, y is 2 x 2, or 4.

In the figure, VW || YZ. Find the value of x, and the measure of YA and WA.
svetoff [14.1K]

Step-by-step explanation:

because VW || YZ, the 2 triangles are similar.

this is given by the rules of equal angles of intersecting lines with parallel lines. Z to V and Y to W would be such intersecting lines.

and therefore, the angle at W is the angle at Y, the angle at V is the angle at Z. and therefore both angles at A are equal.

so, for similar triangles the scaling factor between corresponding pairs of sides is the same for all sides.

e.g. the same scaling factor that converts 7.2 to 12, converts then also x to x+4.

7.2 × f = 12

f = 12/7.2 = 12/ 72/10 = 120/72 = 10/6 = 5/3

x × 5/3 = x + 4

5x = 3x + 12

2x = 12

x = 6

A to Y = x = 6

W to A = x + 4 = 6 + 4 = 10
