timofeeve [1]3 years ago
7 0

Answer:

  A.  (-7 -2)

Step-by-step explanation:

You can eliminate y by multiplying the first equation by 7 and subtracting 6 times the second equation:

  7(-3x +6y) -6(5x +7y) = 7(9) -6(-49)

  -21x +42y -30x -42y = 63 +294 . . . . eliminate parentheses

  -51x = 357 . . . . . . . . collect terms

  x = -7 . . . . . . . divide by -51. This matches answer choice A.

kenny6666 [7]

Answer:

You will save: $15

Total cost: $60

Step-by-step explanation:

First turn the percent into a decimal.

To do so move the . over to the left twice.

20% - .20

Now multiply 75 by .20

75 x .20 = 15

So you will save $15

Now subtract 15 from 75

75 - 15 = 60

Zigmanuir [339]
<span>Experimental Probability is the ratio of the number of times an event occurs to the total number of trials.

Given that </span><span>Cole rolls a number cube multiple times and records the data in the table below. At the end of the experiment, he counts that he has rolled 190 fours.

From the table, we see that the total number of trials is 1,000 and there are 190 fours.

Therefore, the experimental probability of rolling a four, based on Cole’s experiment is given by 190 / 1,000 = 0.19 = 0.190 to the nearest thousandth.</span>

Completely factored form of xy^3 – x^3y?
Zolol [24]

Answer:

xy(y - x)(y + x)

Step-by-step explanation:

take out a common factor xy from both terms

= xy(y² - x²)

y² - x² is a difference of squares and factors in general as (y - x)(y + x)

Hence

xy³ - x³y = xy(x - y)(x + y)
