Hello!
To the value of b, or the y-intercept, we need to substitute an ordered pair/point into the given equation.
Since we are given two points, we can use those two points to find two different equations.
Remember that ordered pairs are written as (x, y).
A(-2, 4)
y = -3x + b
4 = -3(-2) + b
4 = 6 + b (subtract 6 from both sides)
-2 = b
A) Therefore, the equation of the first ordered pair is y = -3x - 2.
B(5, 2)
2 = -3(5) + b
2 = -15 + b (add 15 to both sides)
17 = b
B) The equation of the second ordered pair is y= -3x + 17.
<u>Final answers</u>:
- A) y = -3x - 2
- B) y = -3x + 17
Answer:
The missing number would be a 9
To answer this you can use proportions.
4 1/2 6%
------- = ----
X 100%
So, 6/4.5=1.3333...
Finally, 100/1.3333... appeoximately gives you 75.
75 hours are needed to restore the boat.
Hope this helped!
Answer:
A: $48.53
B: $58.23
Step-by-step explanation:
7% of 45.36 is 3.17.
