What is the value of x?

H. x = 8

Step-by-step explanation:

Let's label the vertices of the large triangle A, B, and C, and the point splitting the hypotenuse of the large triangle into the lengths x and 10 D (I've uploaded a marked up version of the problem to illustrate this step). The large triangle ABC and the small triangle ADC are similar, since they contain all three of the same angles. This means that the ratios between their corresponding sides are equal to each other. Side AB measures x + 10 and corresponds to side AC, which measures x + 4, so the ratio between their sides is . Similarly, side AC (measuring x + 4) corresponds to the side AD (measuring x) for a ratio of . Equating the two, we have

Cross multiplying, expanding and collecting like terms:

So our answer must be H. x = 8.

Ibelieve the answer is a

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
