-0.75 is a rational number because it can be expressed as the fraction -3/4 and it is an integer
Answer:

Step-by-step explanation:
The standard form of a linear equation is
, where
,
, and
are constants in the equation.
Based on the equation you have provided, the standard form would be
, where
.
To find the y-intercept, set
.

Therefore, the y-intercept is
.
Do the same thing for the x-intercept, but this time with
.

Therefore, the x-intercept is
.
The solution to the equation would be 21.5
Why?
If you do the equation backwards
30 - 8.5 = x
You would get 21.5
You can plug it into the first equation to check!

Answer:
2 nickels, 9 dimes
Step-by-step explanation:
When there are a number of overlapping shaded areas on the graph, I find it convenient to use the reverse of the inequalities. That makes the <em>unshaded</em> area the solution space. Here, the vertices of the triangular solution space are ...
(2, 9), (2, 13), (6, 9)
Any of the grid points within (or on) this triangle is a possible solution. One of them is (2, 9) corresponding to 2 nickels and 9 dimes.
__
Three solutions are shown:
(x, y) = (2, 9), (3, 10), (4, 11)
