Answer:

Step-by-step explanation:
<em>In order to calculate the slope m between two points (x1, y1) and (x2, y2), we can use the formula below:</em>
<em></em>
<em></em>
<em>So, for points (4, 2) and (-16, -10), we have:</em>
<em></em>
<em></em>
<em>Therefore, The Answer is </em>
<em />
Step-by-step explanation:
3x + 5y = 21 * (-4) •••••• -12x -20y = -84 (a)
4x - 2y = -24 * (3) •••••• 12x -6y = -72 (b)
(a) + (b)
-26y = -156
y = 6
3x + 5 * 6 = 21
3x = 21 - 30
3x = -9
x = -3
Answer:
-1.5
Step-by-step explanation:
2.5 units towards right of the origin means x = +2.5
1.5 units down means y = -1.5
It depends on how many hours the sailfish swims
Answer:
9+-36=-27 is the sum of 9 and y is at least - 27.
