Answer:

Option 2: none of these

Step-by-step explanation:

-x +2y= 4

x-intercept occurs at y=0.

When y=0,

-x +2(0)= 4

-x= 4

x= -4

Thus, x-intercept is (-4,0).

y-intercept occurs at x=0.

When x=0,

0 +2y= 4

2y= 4

y= 4 ÷2

y= 2

Thus, y-intercept is (0,2).

*When writing coordinates, the x and y coordinates are separated by a comma in the bracket. If the 3rd option is a comma instead of a dot (which could instead denote a multiplication sign), it would be the correct option.

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Ratio of sapphires to emeralds = 3:1

Let the number of sapphires be 3x.

Let the number of emeralds be 'x'.

According to question, if 6 emeralds are added, we get that

$3x=x+6\\\\3x-x=6\\\\2x=6\\\\x=\dfrac{6}{2}\\\\x=3$

So, Number of sapphires = 3×3 = 9

Number of emeralds = 3

So, total emeralds would be 3+ 6 = 9.

Hence, option 'A' is correct.

Lilit [14]

As given,

Number of sheets of paper put in the binder 8 days ago = 50 sheets

Current number of sheets left after 8 days = 2 sheets

So, number of sheets used in 8 days = $50-2=48$ sheets

As it is stated that the same number of sheets are used each day, so number of sheets used per day = $\frac{48}{8}=6$ sheets.

Hence, 6 sheets of paper were used each day.
