Answer:

The correct options are 1 and 3.

Step-by-step explanation:

It is given that x represents the number of small boxes and y represents the number of large boxes.

The post office has 10 small boxes and 9 large boxes in stock.

He needs at least 4 small boxes.

$4\leq x\leq 10$

He will buy no more than 15 boxes.

$6+9=15\leq 15$

$8+6=14\leq 15$

Therefore options 1 and 3 are correct.

$x+y\leq 15$

$7+10=17>15$

$9+8>15$

Therefore options 2 and 4 are incorrect.

FrozenT [24]

Answer:

-3 and -4

Step-by-step explanation:

x = 1st number

y = 2nd number

set up system of equations:

2x + 3y = -18

3x + 2y = -17

elimination method: multiply 1st equation by -2 and second by 3

-4x - 6y = 36

9x + 6y = -51

5x = -15

x = -3

find y: 2(-3) + 3y = -18

-6 + 3y = -18

3y = -12

y = -4

HURRY! (NO LINKS PLEASE)

Hi!

To solve this, we use the slope equation $\frac{y1-y2}{x1-x2}$

With numbers in the equation it looks likes this:

$\frac{9-6}{1-6} = \frac{3}{-5}$ or $\frac{-3}{5}$

Therefore your answer is D.

Hope this helps! :D

Answer:

1. Not proportional 2. is proportional. For 3, 4, 5, and 6 just plot them.

Step-by-step explanation:

For 1, y intercept/x intercept is not 0 when you graph, thus not proportional. Number 2 is, thus proportional. For 3, 4, 5, and 6 you would plot them accordingly. So for (-5, -2) Start as 0,0 and go 5 to the left as it's negative, and 2 down as it is also negative. Do the same for others.

What is the value of y?

RUDIKE [14]

Answer:

C. 55

Step-by-step explanation:

Since all angles in a triangle add up to 180°, we have:

40 + y + y + 30 = 180

2y + 70 = 180

2y = 110

y = 55
