Answer:
You just made a silly mistake. Angle A is 79, not 89. Just be more careful next time. (Remember, this figure is a cyclic quadrilateral whos opposite angles add up to 180)
A mapping system is a way of describing
a C. Preimage of a figure. Mapping statements are known to define the range of
data sources thus showing all the data. While on the other hand, preimage (in
Mathematics) meaning is that set of all the elements of the domain that maps to
the members of S.

13.) A=9cm^2
If the area is l•h, and there are 9 cubic squares, that means that the length of each side on the square is 3cm, each square on it equals 1cm.
14.) V=27cm^3
If the volume is l•w•h, then we find the third power square root of 27, so 3•3=9•3=27, the answer is 3cm for the length, width, and height.
15.) V=4,913cm^3
If volume is l•w•h, then what number when raised to the third power equals 4913? The answer is 17, since 17•17=289•17=4913. So the length is 17cm
16.)V=216cm^3
If volume is l•w•h, then what number when raised to the third power equals 216? The answer is 6, since 6•6=36•6=216.
17.)A=121
Is area is l•w, then what number raised to the second power equals 121? The answer is 11, since 11•11=121. Therefore it WILL NOT fit a car with a length of 13ft.
18.)A=141
If area is l•w, then what number raised to the second power equals 141? The answer is 12, since 11.87•11.87=141 (answer was rounded to nearest whole number) meaning that she will need 12ft of fence to enclose her garden.
The desired inequalities are given as follows:
A. A. x > x + 1. because solving it yields an inequality that is False for all real numbers x.
B. D. x < x + 1, because solving it yields an inequality that is True for all real numbers x.
<h3>Which inequality represents graph A?</h3>
For graph A, as nothing is plotted on the line, we have a inequality with no solution.
The successor of a number(number plus 1), will always be greater than the number, hence the inequality that has no solution is:
A. x > x + 1. because solving it yields an inequality that is False for all real numbers x.
<h3>Which inequality represents graph B?</h3>
For graph B, as the entire line is plotted, we have a inequality with all real values as solution.
From the same logic above, of the successor, the correct option is:
D. x < x + 1, because solving it yields an inequality that is True for all real numbers x.

#SPJ1
Answer:
C
Step-by-step explanation:
A relation is a function if each input gives exactly one output. There is one price for each number of pounds, so the relation is a function.
__
<em>Additional comment</em>
Relations expressed in terms of ordered pairs or tables can be identified as "not a function" if any input (x) value is repeated. Relations expressed as a graph will be "not a function" if any vertical line intersects the graph at more than one point. (This is called "the vertical line test.")
The cost function in this case is a straight line through the origin. It has a slope of $5.99/lb. Any polynomial relation will be a function.
