Answer:
Part A: We know that 3 bushels is $24, and that rate remains constant, as the graph has a straight line.
Divide both sides by 3 to get 1 bushel=$8.
We can also double check with the other values: 48/6=$8 per bushel, 72/9=$8 per bushel, and so on.
The rate of change is the slope of a line (how much one value changes when the other value does). In this equation, the equation of the line is y=8x, so the slope is 8. Therefore, the rate of change is 8.
Part B: In the previous year, each bushel of corn was 21/3, 42/6, etc., or $7 a bushel. This year, it is $8, so $8-$7=$1
Step-by-step explanation:
your welcome
well, let's notice something, we have two 45° angles, now each of those will give use an equal opposite side, namely if that one side is "x", the other is her twin, "x" as well.
is a right-triangle, so we can use the pythagorean theorem, and we know the sides are x,x,6.

area = 15 X 20
area = 300 cm²
Answer:
d. 8°
Step-by-step explanation:
It appears as though you intend ∠ECF and ∠ACB to be vertical angles, hence the same measure, 47°. The angle of interest, ∠BCD, is added to that to make ∠ACD, which is 55°. The added angle must be 55° -47° = 8°.
