Answer:

D.....is\:   the \: equivalent \: system

Step-by-step explanation:

if \to 4x + 5y = 3 \\ if  \to 2x + 3y = 1 \\then \\ 2 \times  \: 4x + 5y = 3 \\ 4 \times 2x + 3y = 1 \\ 10y - 12y = 6 - 4 \\  - 2y = 2 \\ \boxed{ y =  - 1} \\ 4x  +  5y = 3 \\ 4x  +5( - 1) = 3 \\ 4x  -  5 = 3 \\ 4x = 3  + 5 \\ 4x =  8 \\  \boxed{x =  2} \\ hence \: the \: equivalent \: system \: is \to D \\

Answer:

(-1/3, 3/4)

Step-by-step explanation:

9x + 8y = 3

6x - 12y = -11

Let's solve the system by eliminating x. We need the coefficients of x to be additive inverses, so they will add to zero eliminating x. The LCM of 9 and 6 is 18. Let's multiply both sides of the first by 2 and both sides of the second equation by -3.

18x + 16y = 6

-18x + 36y = 33

The coefficients of x are 18 and -18, which add to zero. Now we add these two equations.

52y = 39

y = 39/52

y = 3/4

Now we substitute y with 3/4 in the first equation and solve for x.

9x + 8y = 3

9x + 8(3/4) = 3

9x + 6 = 3

9x = -3

x = -3/9

x = -1/3

Solution: (-1/3, 3/4)

Answer:

y = 90°

Step-by-step explanation:

The left side base angle of the triangle and the angle of 110° form a straight angle and are supplementary, thus

base angle = 180° - 110° = 70°

The right base angle is also 70° , thus the triangle is isosceles

The line segment from the vertex is a perpendicular bisector, hence

y = 90°
