Answer: y = 3
Step-by-step explanation: y−3=2(x+1)
We know that x=-1 and we want to solve for y
Put in x=-1
y-3 = 2(-1+1)
y-3 = 2(0)
y-3=0
Add 3 to each side
y-3+3 = 0+3
y =3
Answer:
see the graph below
Step-by-step explanation:
If you add 1-y to both sides, the equation will be in intercept form:
x/3 - y = 1
This tells you the x-intercept is (3, 0) and the y-intercept is (0, -1).
The graph of the equation is the line through these points.

<em>Comment on intercept form</em>
When the equation is written as
x/a + y/b = 1
the x-intercept is "a", and the y-intercept is "b".
I find it convenient to use this form when I want to find both intercepts of the linear equation.
Answer:
Step-by-step explanation:
Let the base camp is point A and boats' locations after two hours are points B and C.
By connecting the three points together we get a triangle ABC with sides:
- AB = 50*2 = 100 km
- AC = 70*2 = 140 km
The angle between AB and AC is:
- 60 + 50 = 110 degrees (opposite directions from south)
We are looking for the distance BC, which can be found by using the law of cosines:
- BC² = AB² + AC² - 2AB*AC*cos ∠BAC
- BC² = 100² + 140² - 2*100*140*cos 110°
- BC² = 39176.56 (rounded)
- BC = √39176.56 = 197.93 km (rounded)
The distance between the boats is 197.93 km.
