Solve the system of linear equations below.
Mrac [35]

Answer:

I am not sure which one it is due to what you put in. I think it would be A.

x = 0

y = 2/3

Step-by-step explanation:

Step: Solve x + 6y= 4 for x:

x + 6y + −6y = 4 + −6y

x= −6y + 4

Step: Substitute −6y + 4 for x in 2x + 3y = 2:

2x + 3y = 2

2 (−6y + 4) + 3y = 2

−9y + 8 = 2

−9y + 8 + −8 = 2 + −8

−9y = −6

-9y/-9 = -6/-9

y = 2/3

Step: Substitute 2/3  for y in x = −6y + 4:

x = −6y + 4

x = -6 (2/3) + 4

x = 0

Sorry if it is long and confusing. But I hope this helps!

What is the effect on the graph of f(x) = 1 when it is transformed to
ivann1987 [24]

Answer: C) Shifted 16 units down

The minus 16 at the end is directly the reason why. Think of y = 1/x, and subtracting 16 from both sides to get y-16 = (1/x) - 16. The y-16 will shift every point down 16 units. For instance, the point (1, 1) moves to (1, -15).

Identify the congruent triangles in the figure.
Komok [63]

Answer:

The answer would be HFG = KIJ (A)

If we know that the opposite and the adjacent side of the triangle are congruent, then the hypotenuse is congruent too. Therefor, A is correct as we know the opposite side and the adjacent side are congruent.
