Answer: D / none are true
Since it's proportional (it's a straight line), B and C are automatically wrong. A would seem true at first glance, <u>BUT </u>if you look closely at the graph, the slope of the graph is actually 2x.
Look at the beginning of the line. It starts at 18 (x = 0/y intercept) and at x = 1, you can see that y is at 16. The y value goes down by 2 every time x increases by 1. This means that the equation of the graph is -2x + 18 = y.
The graph is proportional and has an equation of y = -2x + 18. This means that A, B and C are incorrect.
Answer:
Yes it is
Step-by-step explanation:
Answer:
A. Brian will need 1.75 (1 3/4) cups of flour
B. Brian will need 1 1/16 cups of sugar
Step-by-step explanation:
Brian wants to make it for 3 people, so everything must be divided by 4 since 12/4=3.
7/4=1.75
4 1/4 divided by 4=1 1/16
Answer:
Step-by-step explanation:
Let x equal the first mile marker. Then x + 1 represents the second mile marker.
Then x + (x + 1) = 561, or
2x + 1 = 561, or
2x = 560, and so x = 280
Then the first mile marker reads 280 and the second mile marker reads 281.
