Answer:

The correct option is 1.

Step-by-step explanation:

A relation is called a function if there exist one value of y for each value of x.

In a mapping first set represent the value of x and second set represent the value of y.

In mapping 1, for $x=-5$ , the value of y is -4 and 3. For single of x there exist more than one value of y, therefore this relation is not a function.

In mapping 2 and 3, for all values of x, the value of y is unique. For single of x there exist only one value of y, therefore these relations are function.

Therefore mapping 1 does not represent a function. Option 1 is correct.

Answer:

The correct answer option is A.

Step-by-step explanation:

A process or a relation is said to be function such that each element of a set X is associated to only one single element of another set Y.

Here, in the given mapping diagrams, the set on the left represents x and the set on the right represent y.

Out of the given relation, the first mapping set does not represent a function as one value of x is associated with two values of y.

Two brothers each purchase a new pair of hiking boots and two canteens. The hiking boots cost 34.00 each. The total of their pur

polet [3.4K]

Answer:

The cost of one canteen is $7.5

Step-by-step explanation:

We are given the following in the question:

Each brother purchase a new par of boots and two canteens.

Cost of one hiking boots = $34.00

Total cost of hiking boots =

$=34\times 2\\=\$68.00$

Let x dollars be the cost of one canteen.

Number of canteens bought by both brother = 4

Total bill = $98.00

Thus, we can write the equation:

$68 + 4x = 98$

Solving the equation, we get,

$68 + 4x = 98\\4x = 98-68\\4x = 30\\x = 7.5$

Thus, the cost of one canteen is $7.5

Rearrange the equation so uuu is the independent variable. -12u+13=8w-3

Semmy [17]

Answer:

u = 8w-16 /-12 or = - 8w-16/12 both mean the same due to the a/-b- = -a/b rule. Then you can factor out the rest. note the fnew subtraction changes mean the same as - (a/b) and should show without brackets as a centre pointing whole fraction subtraction sign.

Step-by-step explanation:

-12u -13 = 8w-3

-12u+13 -13 = 8w-3-13 Eliminate -13 by +13 both sides

-12u = 8w-16 So you are left with one value left side.

-12u/-12 = 8/-12 - 16/-12 Then divide all values by -12 to find value for u and keep the subtraction as 8 never had subtraction sign and no multiplication .

u = 8w-16 /-12 Then you can factor out the rest

This has made u the independent variable then you have a choice to continue showing or ignore u; as u =

= - 8(w-2)/12 Step 1 Factor with subtraction change from -12 to - central fraction

= - 2(w-2)/3 Step 2 Simplify with new minus sign for central fraction to replace a/-b

DochEvi [55]

1 yard = 3 feet
2/3 of a yard would be 2 feet

4.5 yards = 13.5 feet
13.5-2 = 11.5 feet

11.5 feet = 3.83 yards

therefore at least 11.5 feet or 3.83 yards must be purchased
