Answer:
The length of DE is 5 because they are similar triangle .
NQ
This is because you have to see what R is congruent to (based off the order) and you see N. Then you do the same thing for T and you get Q.
$0.25 = 5 bottles
Divide both sides by 5:
$0.05 = 1 bottle
Last week: $12.75
12.75 = 0.05b where b represents bottles
Divide all by 0.05 to get b alone:
255 = b
Answer:
y = 3.75x+5
Step-by-step explanation:
*** some of your points might be wrong ***
1. Take two points on the line. Ex: (0, 5) and (4, 20)
2. Find the slope using the change in y divided by the change in x.
Ex: m=(20 - 5)/(4 - 0) = 15/4 -> m= 3.75
3. Look at the graph for the y-intercept (when x =0)
y -intercept -> b = 5
Check:
y = mx + b; m = 3.75 (4, 20) -> x= 4 and y =20
20 = 3.75(4) + b
20 = 15 + b
5 = b
4. plug in to slope-intercept form: y = mx +b
y = 3.75x+5
