Answer:
y = x + 1
See below.
Step-by-step explanation:
To find the slope intercept form of a line, calculate the slope first.
So the slope is 1. Substitute m = 1 and (1,2) into the point slope form. Then simplify to slope intercept form.
y - 2 = 1 (x - 1)
y - 2 = x - 1
y = x + 1
Its 400 ..... hope that helps :)
Answer
b
highest he should make is 3599.55 and lowest is 3332.55 so a doesnt fit and b does
Answer:
100g : 60g : 80g
Step-by-step explanation:
5+3+4 =12 total parts
(5/12 of 240)
5/12 x 240 = 100g
3/12 x 240 = 60g
4/12 x 240 = 80g
Check:
100g + 60g + 80g = 240g
Hope this helps!
Answer:
Step-by-step explanation:
Let he speed of the boat on the lake is x.
<u>Considering the speed of the current it will take him:</u>
- 22.5/(x + 6) + 22.5/(x - 6) = 9
- 2.5 / (x + 6) + 2.5 / (x - 6) = 1
- 2.5(x - 6 + x + 6) = (x + 6)(x - 6)
- 2.5*2x = x² - 36
- x² - 5x - 36 = 0
- x = (5 ± √(5² + 4*36))/2 = (5 ± 13) / 2
- x = (5 + 13)/2 = 9 mph (negative root is discarded as the speed should be positive)
