Step-by-step explanation:
(f+g)(x) means f(x) + g(x).
(f−g)(x) means f(x) − g(x).
So all you have to do is add them and subtract them.
1. (f+g)(x) = f(x) + g(x)
(f+g)(x) = (3x − 7) + (2x − 4)
(f+g)(x) = 5x − 11
2. (f−g)(x) = f(x) − g(x)
(f−g)(x) = (3x − 7) − (2x − 4)
(f−g)(x) = 3x − 7 − 2x + 4
(f−g)(x) = x − 3
3. (f+g)(x) = f(x) + g(x)
(f+g)(x) = (2x + 3) + (x² + ½ x − 7)
(f+g)(x) = x² + 2½ x − 4
4. (f−g)(x) = f(x) − g(x)
(f−g)(x) = (2x + 3) − (x² + ½ x − 7)
(f−g)(x) = 2x + 3 − x² − ½ x + 7
(f−g)(x) = -x² + 1½ x + 10
Answer:
The point represents a 36 months old Panda whose weight is 82kg
Step-by-step explanation:
Given
See attachment for plane
Required
What does the point shown represent
The point is: (36,82)
Age is plotted on the x-axis and weight on the y-axis:
This means that:
<em>So, the point represents a 36 months old Panda whose weight is 82kg</em>
Answer:
2x-9y=-51
2x-3y=-9
subtract question ii from i we get
-6y = -42
y =7
put value of y in 1
2x - 63 = -51
2x= 8
x=4
Answer:
JL = 56
NK = 28
Step-by-step explanation:
Since JL = MK
5x + 1 = 8x - 32
8x - 5x = 32 + 1
3x = 33
x = 11
so
JL = 5x + 1 = 5(11) + 1 = 55 + 1 = 56
NK = 1/2MK = 1/2JL = 56/2 = 28
