Is 10=5x-6y written in standard form?

1 answer:

7 0

No, the standard form for a straight line is in the form:

ax + by + c = 0

Since the 10 is on the LHS, you'd need to move it to the RHS to fit the straight line form and then moving everything to the LHS.

0 = 5x - 6y - 10
5x - 6y - 10 = 0 is the standard form.

How do I solve for x since the triangles are similar?

Llana [10]

A line that is parallel to a side and intersects the other two siddes divides the sides proportionally.

Set up the proportion

DE is a midsegment of AABC . Find the value of x .<br> B<br> х<br> 5<br> А

Ugo [173]

Answer:

x = 10

Step-by-step explanation:

DE is the midsegment joining the midpoints of BC and AC respectively.

Therefore, by the property of midsegment of a triangle,

DE will be parallel and half of the measure of the third side of the triangle.

DE = $\frac{1}{2}(AB)$
