Answer:
y = 4/5x - 3
Step-by-step explanation:
The slope-intercept form of a line is y = mx + b. We need to isolate the y.
(add 4x to 15)
-4x + 5y = 15
5y = 4x + 15
(divide by 5 from both sides)
y = 4/5x + 15/5
y = 4/5x + 3
4x-3y=-9
The first step is to isolate your y value.
Subtract 4x from both sides to get
-3y=-4x-9
Then, divide your whole equation by -3. This gives you y=4/3+3
To graph, plot (0, 3), or three on your y-axis to get your y-intercept.
For your slope, use the rise/run (go up 4, across 3)
You should have a positive slope.
The total cost will be ...
... cost = 3×$32 + 1×$53 + h×$5
In dollars, that simplifies to
... cost = 5h + 149
Answer:
C
Step-by-step explanation:
f(x)=0 at points of intersection of the graph of the function with x-axis.
From the diagram you can see that the graph of the function intersects x-axis at three points:
somewhere between -3 and -2;
somewhere between -1 and 0;
at x=1.
Since x=1 is the value of x from the domain, then correct choice is option C.
You find the overall change in temperature by adding them together.
-8 would be from were is decreased 8 degrees and +8 would be from where it increased 8 degrees
Like: -8+8=0
