Answer:
Step-by-step explanation:
We are given the slope along with an (x, y) coordinate with which to write the equation. You could use this info in the slope-intercept form and solve for b, or you could use this info in the point-slope form and solve it for y. Trust me when I tell you that either one will get you the correct equation. Promise! I used the point-slope form, just because. ; )
y - 2 = 3(x - 1) and
y - 2 = 3x - 3 and
y = 3x - 1 OR in standard form, we will put the x and y terms on the same side of the equals sign, separated from the constant:
-3x + y = -1. But if we get picky and do not like to lead with negatives, we could change ALL the signs to their opposites (which is the same as multiplying the whole thing by a -1) to get
3x - y = 1 which is the third choice down.
<em>- What two consecutive odd integers have a sum of 48</em>?
23 + 25 = 48
- <em>Two negative consecutive integers have a sum of -45. What are the integers?
</em>
<em />-22 + -23
- <em>The sum of two consecutive integers 75. What are the two integers?</em>
37 + 38 = 75
- <em>What <u>three</u> consecutive odd integers have a sum of 81?
</em>
<em />25 + 27 + 29 = 81
Hope I could help! Have a good one. I believe that is all of the unanswered questions. If I missed one, let me know!<em />
Answer:
4 horses maybe
Step-by-step explanation:
you might subtract the 4 horses from the left to get 8 horses in the right but that's equal to 2 elephants so divide 8 by 2 to get the 1 elephant so 4 maybe
Only 3 is needed
Step-by-step explanation:
Answer:
x = 8 and y = 5
Step-by-step explanation:
2x - 3y = 1 --(1)
x + 2y = 18
x = 18 - 2y --(2)
sub (2) into (1):
2(18 - 2y) - 3y = 1
36 - 4y - 3y = 1
-7y = 1 -36
7y = 35
y = 5
x = 18 - 2(5) = 8
