Can u guys please help me with the second problem

-3x+6y+5=-7
-3x+6y=-12
6y=3x-12
y=1/2x-2
Since the y-intercept of this graph is -2, we can automatically say that point (0,-2) is on the graph.
Then you can just plug the x value of each point into the equation and see if you get the right y value.
to test point (6,-3) plug in x=6 to get (6/2)-2 which equals 1. since the y value when x=6 is 1 instead of -3, we can say that this point is not on the graph.
repeat that step for each of the given points.
when done correctly you should get that points (0,-2) and (8,2) are on the graph.

2x + 5y = 19
x - 2y = - 4
Answers
Answer:
Step-by-step explanation:
｡☆✼★ ━━━━━━━━━━━━━━ ☾
2x + 5y = 19
x - 2y = -4
Multiply the second equation by 2
2x - 4y = -8
Now we have:
2x + 5y = 19
2x - 4y = -8
Subtract the second eq from the first to get:
9y = 27
/ 9
y = 3
Now substitute this value into one of the first equations
x - 2(3) = -4
x - 6 = -4
x = 2
Thus, your answer would be option B

There can be 9 arrays.
Step-by-step explanation:
We are asked that the number of arrays that Courtney can make with 36 photos.
The dimensions of the possible arrays are
Here, the array with 1 row by 36 columns and 36 rows by 1 column are different. (Answer)
Final answer:
Arrays represent sets of elements in rows and columns. Courtney can make 9 different arrays with her 36 photos: 1x36, 2x18, 3x12, 4x9, 6x6, 9x4, 12x3, 18x2, 36x1.
Explanation:
An array represents a set of elements organized in rows and columns. It is a way to represent multiplication and division. Here, we must determine all possible ways Courtney can arrange her 36 photos.
The possible arrays, or divisions of 36, include:
- 1 row of 36,
- 2 rows of 18,
- 3 rows of 12,
- 4 rows of 9,
- 6 rows of 6,
- 9 rows of 4,
- 12 rows of 3,
- 18 rows of 2,
- and 36 rows of 1.
So, Courtney can make 9 different possible arrays with 36 photos.
