Answer:
Intersect: (4 4/7 , 2 6/7)
Step-by-step explanation:
A: slope (m)= (-10-8) / (-9 - 10) = 18/19
Equation: y-8 = 18/19 * (x-10)
18x -19y = 28 (1)
B: slope (m) = (12 - -2) / (0 - 7) = -2
equation: y-12 = -2 *(x - 0)
2x + y = 12
38x + 19y = 228 (2)
(2) + (1): 56x = 256 x = 4 4/7
y = 12 - 2x = 12 - 64/7 = 2 6/7
The answer is 20 because you plug in x=2 into f(x)
Answer:320
Step-by-step explanation: 8 bats equals 40 grams of insect. 8 x 5= 40. 64 bats equals 320. 64 x 5 =320.
