Answer:
Erica did
Step-by-step explanation:
60% of 30 is 18
20% of 70 is 14
Multiply tvs sold by cost of the warranty:
17 x 20 = $340
Subtract the total warranty from total made and divide by number of TVs.
1360 - 340 = 1020
1020/17 = 60
He earns $60 per tv
Answer:
slope = m = 1
Step-by-step explanation:
y = x + 5
slope intercept form is y = mx + b, where m is the slope.
in this case, the m = 1; therefore, the slope is 1
Answer:
a) y = 6x - 3
b) 1/3y = 2x -1
The first thing you need to do is isolate (y) in the second equation
3 x (1/3y) = 3 x (2x - 1)
y =6x - 3
After isolating (y) in equation b they end up being the same.
Graphing:
In order to graph this, you have to make the first point at (0, -3) since this is the Y-intercept of the equation.
In order to graph the other points, you must move 6 units up and 1 unit to the right. Or vise versa If you need a visual I'll gladly link one.
Answer: The graph is attached.
Step-by-step explanation:
By definition, the line intersects the y-axis when 
.
Then, in order to find the y-intercept, substitute into the equation and solve for "y":
By definition, the line intersects the x-axis when 
.
Then, in order to find the x-intercept, you can substitute into the equation and then you must solve for "x". Then you get:
Knowing that the line passes through the points 
and 
, you can graph it (The graph is attached).
