Answer:
Step-by-step explanation:
Answer: y=-4x+7
Step-by-step explanation: Move 8x to the right side to isolate y. 2y=14-8x. Divide the whole equation by 2 to get y by itself. y=7-4x
Answer:
b. g(x)=|x+3|-1
Step-by-step explanation:
We first determine the z-scores for the given x-values of 64 and 96.
For x = 64: z = (64 - 80) / 8 = -2
For x = 96: z = (96 - 80) / 8 = 2
Therefore we find the probability that -2 < z < 2, which is around 0.95. Therefore, out of 100 students, approximately 100(0.95) = 95 students will weigh between 64 and 96 pounds.

Answer:
1406.25 square yards
Step-by-step explanation:
To find the number of square yards represented by one square inch, divide the number of square yards by the number of square inches.
(9000 yd²)/(6.4 in²) = 1406.25 yd²/in²
Each square inch represents an area of 1406.25 square yards.
