Answer:

<h2>First, second and fifth option can be selected.</h2>

Step-by-step explanation:

The given equations are Ax + By = C and Dx + Ey = F

If one multiple of equation 1 replaces it, then it is nothing but the same equation itself, hence first option can be selected.

If the sum of equation 1 and 2 will replace equation 1 then, it will show some additional data in the changed equation. Hence, second option can also be selected.

If we replaced the equation 1 with (A + D)x + By = C then the system of equations will take us to a different solution. Hence, the third option can not be selected.

Fourth option is same as the third option, here the difference is just the another variable is chosen. It can not be selected.

Fifth option can be selected as it changes the equation 1 by multiplying the given data of 1 and 2 with some value and adding them.

Points S,U, and T are the midpoints of the sides of PQR. Which statements are correct ? 1/2QP=UT 1/2TS=RQ SU=PR SU||RP UT=RP

cricket20 [7]

Answer:

$\frac{1}{2} QP = UT$

Step-by-step explanation:

GIVEN : In ΔPQR

S is the mid point of QP

U is the mid point of PR

T is the mid point of QR

Solution :

i) is true i.e $\frac{1}{2} QP = UT$

Refer the attached file

By mid segment theorem i.e. In a triangle, the line joining the midpoints of any two sides will be parallel to the third side and that same line joining the midpoints is also half of length of third side .

UT is the line joining the two mid points . So, by theorem given above UT is parallel to PQ and 1/2QP=UT.

So, (i) statement is true i.e. $\frac{1}{2} QP = UT$
