Masteriza [31]3 years ago

For this case, we use a generic expression given by:

a * b = c\\

The commutative property establishes that the order of the factors does not alter the product, that is, the previous expression can be written as:

b * a = c\\

Thus, the commutative of 5 * 6 = 30 is given by:

6 * 5 = 30\\

Answer:

Option c

At a local grocery store, bananas were on sale. Green bananas were priced at $14.00 and yellow bananas were priced at $12.00. Sa
garri49 [273]

Answer:

Sabrina bought 6 yellow bananas and 3 green bananas

Step-by-step explanation:

Let

Green bananas = x

Yellow bananas = y

Green bananas = $14.00

Yellow bananas = $12.00

Total cost = $114.00

x + y = 9 (1)

14x + 12y = 114 (2)

From (1)

x = 9 - y

Substitute x = 9 - y into (2)

14(9 - y) + 12y = 114

126 - 14y + 12y = 114

- 14y + 12y = 114 - 126

-2y = -12

Divide both sides by -2

y = -12 / -2

= 6

y = 6

Substitute y = 6 into (1)

x + y = 9

x + 6 = 9

x = 9 - 6

= 3

x = 3

Flura [38]

The average of 6 quiz scores, where x is the score of the last quiz, is

\dfrac{83+81+89+92+80+x}6=\dfrac{425+x}6

The student needs a minimum average of 86 to earn an A:

\dfrac{425+x}6=86\implies425+x=516\implies x=91

so the student needs a score of 91.

How is the function shown below related to y=x? Graph the function by translating the parent function y=x+5
AveGali [126]

Consider x=0.

The output of the function y=x is y=0.

The output of the function y=x+5 is y=0+5, or y=5.

The value 5 is not 5 less than 0, not 1/5 of 0, and not 5 times 0. Rather, it is 5 more than 0, corresponding to selection ...

... C. Each output of y=x+5 is 5 more than the corresponding output of y=x.
