Answer:
the answer is 4
Step-by-step explanation:
if y=21 the we substitute in the main equation
21=8x-11
8x=32
x=4
9514 1404 393
Answer:
A) $8/bushel (divide dollars by bushels)
B) $2
Step-by-step explanation:
A) We observe that the graph is a straight line through the origin, so we know the price is proportional to the quantity. The "rate of change" is the ratio of price to quantity, which can be figured using any point on the graph.
For easy division by quantity, it is convenient to use the point for 10 bushels. That price is $80, so the "rate of change" is ...
price per bushel = $80/10 = $8 . . . per bushel
__
B) The same calculation can be done for the previous year. Any line of the table will do.
price per bushel = $12/2 = $6
The current year price is greater by ...
$8 -6 = $2 . . . per bushel
Answer:
The scale factor for the dilation is 3.
Step-by-step explanation:
We are given that,
Rectangle ABCD is dilated to form the rectangle A'B'C'D'.
<em>To find the scale factor, we will find the ratio of the lengths of the rectangle.</em>
We see that,
A= (1,5) and B= (4,5). So, the length of side AB = 4-1 = 3
A'= (3,15) and B'= (12,15). So, the length of side A'B' = 12-3 = 9
So, the ratio of the sides AB : A'B' = 3 : 9 = 1 : 3.
Hence, we get that,
<em>Length of side A'B' is 3 times the length of side AB.</em>
This relation can be verified for other sides also.
Thus, the scale factor for the dilation is 3.
The answer is 22, it would have to be much larger for it to be 32
Answer:
on the first triangle it is equal, 1.5 on the left of it is half of 3 on the right triangle, 5 on the left is half of 10 on the right triangle. so the answer is 8 becuase each side on the left is 2 times the side on the right
Step-by-step explanation:
