Mathematics
1 answer:
Vadim26 [7]3 years ago
3 0

Answer:

8x^{a+b}+4x^{3+a}-10x^{a+1}

Step-by-step explanation:

We need to find the product of: -2x^{a}(-4x^{b}-2x^{3}+5x)

We have that:

-2x^{a}(-4x^{b}-2x^{3}+5x) = 8x^{a+b}+4x^{3+a}-10x^{a+1}

We can't simplify more the expression, therefore, the solution is:

8x^{a+b}+4x^{3+a}-10x^{a+1}.

What is the solution of the inequality 7(x + 4) < 2(x–5) + 3(x + 9)?
emmasim [6.3K]

Answer:

x< -8.125

Step-by-step explanation:

7(x+4) < 2(x-5) -3(x+9)

distribute 7, 2, -3 to the parentheses to the right

7x+28<2x-10-3x-27

add like terms

7x+28<x-37

add x to 7x and subtract -28 to -37

8x<-65

divide both sides by 8

x<-8.125 or (-65/8)

First move the terms to get
6m-m=13+2
Then collect the like terms and calculate the sum, 5m=15
Divide both sides by 5
And you get m=3

Marcy had 9.98 pounds of sauce. She wants to put them into 2 equal bags. How many pounds of sauce will be in one bag?
aksik [14]
If Marcy would want to have 2 bags with the equal amount of sauce from a 9.98 pound bag of sauce, then all she needs to do is to divide the total amount of sauce, which is 9.98, by 2 bags. So if she would do this, then the equation will be 9.98/2. The answer to this problem would be 4.99 pounds of sauce per bag. This makes since because 4.99 pounds (in the first bag) + 4.99 pounds (in the second bag) will make up 9.98 pounds which is the total amount of sauce Marcy has.

The relation R is shown below as a list of ordered
Dmitrij [34]

Answer:

(1, 4) and (1,3), because they have the same x-value

Step-by-step explanation:

For a relation to be regarded as a function, there should be no two y-values assigned to an x-value. However, two different x-values can have the same y-values.

In the relation given in the equation, the ordered pairs (1,4) and (1,3), prevent the relation from being a function because, two y-values were assigned to the same x-value. x = 1, is having y = 4, and 3 respectively.

Therefore, the relation is not a function anymore if both ordered pairs are included.

<em>The ordered pairs which make the relation not to be a function are: "(1, 4) and (1,3), because they have the same x-value".</em>
