Answer:
(a) and (b) are true
Step-by-step explanation:
a) is true.
b) is true. Replacing x with 8 in the equation y=1/4x-5 results in 2-5, or -3.
c) is false. See (a), above.
d) is false. Replacing x in the equation by 12 results in y = (1/4)(12) - 5, or -2.
Answer:
The simplest way to teach middle school math scale drawings is to use real pictures to relate to each other to explain the concept. For example, scaling a red ball of 1" to a ball of 2" and so on. This will show how the ball increases by size by adding 1" each time.
Answer: x = 6, the y - coordinate is 4, therefore the value of the function when x = 6 is 4.
