(-∞,-2] U [2,∞)
Step-by-step explanation:
Answer:
(1, 2/3) (-1, -1) are the points. use the slope formula to find the slope y2-y1/x2-x1
(-1 - 2/3) / (-1 -1) (answer both sides of the division side)
-5/3 / -2 (divide)
slope = 5/6 (the slope)
plug in values you know into point-slope form (y -y1) = m(x-x1)
y - (-1) = 5/6 (x - (-1) (i chose the easier point to plug in. two neg. make a pos. )
y +1 = 5/6 (x +1) (use the distributive property)
y +1 = 5/6x+5/6 (subtract 1 from both sides)
y = 5/6x - 1/6 or B (this is the equation)

The kilogram of grass eaten by the cow is 7kg and the kilogram of grass eaten by the horse is 6kg.
<h3>The two simultaneous equations that can be derived from the question:</h3>
9h + 45c = 369 equation 1
4h = 3c + 3
4h - 3c = 3 equation 2
Where:
c = kg eaten by cows
h = kg eaten by horses
<h3>What is the value of h?</h3>
In order to determine the value of h, multiply equation 2 by 15
60h - 45c = 45 equation 3
Subtract equation 3 from equation 1
69h = 414
h = 6kg
<h3>
What is the value of c?</h3>
Substitute for c in equation 2
4(6) - 3c = 3
24 - 3c = 3
21 = 3c
c = 7
