Answer:
And....what are the options? or are we suppose to know answer that?
Answer:
We have a total of 7200 plants.
The plants are distributed in one field with 18 rows of 200 plants and another field with 9 rows of N plants.
Where we want to find the value of N.
The total number of plants in the rows is:
"number of rows times number of plants in each row."
Then the total number of plants is:
18*200 + 9*N
And we know that we have a total of 7200 plants, then:
18*200 + 9*N = 7200
9*N = 7200 - 18*200 = 3600
N = 3600/9 = 400
Then the plants are distributed in 18 rows of 200 plants for one field, and 9 rows of 400 plants in the other field.
Answer:
A
Step-by-step explanation:
because the difference between each new number y(-2, -4, -6, -8) x(3, 6, 9, 12) is the same. For the y column it decreases by 2 each time and for the x column it increases by 3 each time. Therefore, yes, -2/3 is the correct answer
Answer:
x=13/5
Step-by-step explanation:
Answer:
First turn 3x + y = -5 to slope-intercept form (y=mx+b) by subtracting 3x in order to move it to the other side, to get
y = -3x - 5.
So now you have all three lines in proper slope-intercept form. (Don't worry about
y = 7 - 3x, it's still in slope-intercept form, despite the y-intercept and slope being swapped.)
<u>Here are the lines rewritten below</u>.⤵⤵⤵
1. y = -3x - 5
2. y = -3x + 7 or y = 7 - 3x (either way works)
3. y = -3x + 2.5
As we can see, all three lines are parallel.
Because all the slopes are the same and the y-intercepts are different. If the slopes were different, the lines wouldn't be parallel.
I also graphed the lines above, so you can see what I mean.⤴⤴⤴ Hope this helped :)
