Solve the inequality r-(-5)>-2
1 answer:
Answer:
Step-by-step explanation:
Solving an inequality is similar to solving an equation. To solve for r, isolate it. Whatever you do to one side, do to the other. Remember that a negative and a negative equal a positive, thus one side of the inequality becomes r + 5. Then, subtract both sides by -5 to find the answer.

Step-by-step explanation:
The equation of a linear function in a slope-intercept form is written as
where
m is the slope of the line
q is the y-intercept
We proceed as follows. First of all, we find the y-intercept, which is the value of y at which the line touches the y-axis.
From the graph, we see that this occurs at y = 4, therefore the y-intercept is
Now we have to find the slope. We do that by choosing two points along the line, with coordinates and
and by using the equation
Here we take the two points:
(0,4)
(-8,0)
So the slope is
Therefore, the equation of the line is

Step-by-step explanation:
The cost (in dollars) in making b bracelets is represented is
The cost (in dollars) of making b necklaces is
To find how much more it will cost to make b necklaces than b bracelets, we find the difference,
This is a polynomial in descending powers of b, hence it is in standard form;
