Below is the complete solution :
-
two points on earth are :
(39N,120W) and (41N,84W)
midpoint between them = <span>(<span><span>39+41/</span>2</span>N, <span><span>120+84/</span>2</span>W)
= </span>(802N, 104/2W)
= <span>(40N,52W<span>)</span></span>
It's a linear function. The graph is a straight line, therefore we need only two points.
Select any value of x and calculate the value of y:
y = -3x + 4
for x = 0 → y = -3(0) + 4 = 4 → (0, 4)
for x = 2 → y = -3(2) + 4 = -2 → (2, -2)
Answer:
B) 25
Step-by-step explanation:
First, you add up all the numbers. Then, you divide it by 9 which is the total amount of numbers there are.
