Convert to mixed number;
The 2nd selection is correct.
_____
If your relation has some point (x1, y1), the inverse relation has the point (y1, x1). For example, one of the points of your relation is (-1, 0), so (0, -1) will be a point in the inverse relation.
A relation is a function if it does not contain two or more points with the same x-value.
(The relation shown in the graph is NOT a function, but its inverse relation IS a function.)

Answer:
(c) 5y - x = -20
Step-by-step explanation:
When the x- and y-terms are on the same side of the equation, the slope of the line will be ...
m = -(coefficient of x)/(coefficient of y)
So, the slopes of the offered choices are ...
a) -5/1 = -5
b) -1/5
c) -(-1)/5 = 1/5 . . . . . parallel to given line
d) -5/-1 = 5
The lines will be parallel when their slopes are the same. The slope of the given line is the coefficient of x, 1/5. Choice C has the same slope.
Thus is how you write y=2x-7 in a function notation. ANSWER:F(x)=2x-7.
Answer:
n = 62 + x
Step-by-step explanation:
From the problem given, it is clear that the orange has LESS calories than a nectarine. <em>HOW much less? "x" less.</em>
<em />
Also, orange has 62 calories. So, nectarine MUST HAVE 62 + x calories.
<em>If we let nectarine's calories be n, we can write:</em>
<em>n = 62 + x</em>
