The answer if 7 years, if you multiply 2,000 by .02 it equals 40. so you divide 280 by 40 and get 7

(3x^2) (2x^5)<br>use the properties of exponents to simplify​
Solnce55 [7]

Answer:

6x^7.

Step-by-step explanation:

The exponent property for this would be that

x^a * x^b = x^a + b.

So x^2 * x^5 = x^2 + 5 or x^7.

The other part is just multiplying the coefficients 3 and 2, which is 6.

Put these together and you get your answer 6x^7.

6x^2-4xy-15xy+10y^2 factor by grouping
PtichkaEL [24]

Best Answer
We will need to split the middle term and use the grouping method. To do this multiply the coefficient of the first term (6) against the coefficient of the last term (10):

6 * 10 = 60
Factors of 60 = +-(1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60)

From the list of factors find two numbers that when added together give -19 and when multiplied together give 60. -15 and -4 added together give -19 and multiplied together give 60 so split the middle term by rewriting these values back into the expression:

6x^2 - 15xy - 4xy + 10y^2

Now use the grouping method, take out the highest common factor between the two sets of terms:

3x(2x - 5y) - 2y(2x - 5y)

Group the outside terms:

(3x - 2y)(2x - 5y)


Answers
6 = -3*-2
10 = 5*2
5*3+2*2=19
thus
(2y-3x)(5y-2x)

YALL HELP!!!!!!!!!!!!!!
QveST [7]

Answer:

The second choice

Step-by-step explanation:

In most cases, the dependent variable is the y value in the graph.

The dependent variable is the thing that is being measured or changing.

In this example it can't be the time because time is always moving at a constant rate and there is nothing that can be done to change it.
