Solve by any method -7x-4y=-4. 14x+10y=24

Answers

Answer 1

Answer: x=−4.895105y

Step-by-step explanation:

−7x−4y=−4.14x+10y

Step 1: Add 4.14x to both sides.

−7x−4y+4.14x=−4.14x+10y+4.14x

−2.86x−4y=10y

Step 2: Add 4y to both sides.

−2.86x−4y+4y=10y+4y

−2.86x=14y

Step 3: Divide both sides by -2.86.

−2.86x

−2.86

=

14y

−2.86

x=−4.895105y

Given:

The zeros of the polynomial are [tex]-2,\pm 5,4[/tex].

Degree = 4

Leading coefficient  = 1

To find:

The polynomial.

Solution:

If c is a zero of a polynomial, then (x-c) must be a factor of the polynomial.

Here, -2,4,-5, 5, are zeros of the required polynomial, so (x+2), (x-4), (x+5), (x-5) are factors of required polynomial.

[tex]p(x)=(x+2)(x-4)(x+5)(x-5)[/tex]

[tex]p(x)=(x^2-4x+2x-8)(x^2-5^2)[/tex]     [tex][\because a^2-b^2=(a-b)(a+b)][/tex]

[tex]p(x)=(x^2-2x-8)(x^2-25)[/tex]

Using distributive property, we get

[tex]p(x)=x^2(x^2-25)-2x(x^2-25)-8(x^2-25)[/tex]

[tex]p(x)=x^4-25x^2-2x^3+50x-8x^2+200[/tex]

On combining like terms, we get

[tex]p(x)=x^4-2x^3+(-25x^2-8x^2)+50x+200[/tex]

[tex]p(x)=x^4-2x^3-33x^2+50x+200[/tex]

Here, the leading coefficient is 1. So, it is the required polynomial.

Therefore, the correct option is E.

Subtracting a number is the same as adding its additive inverse. For which elevation do we need to find the additive inverse?

Answers

Answer: I need to find the additive inverse of the number being su tracked. That number is -9.6. The additive inverse of -9.6 is 9.6.

Step-by-step explanation:

Answer:

Additive inverse can be defined as adding a number with the opposite or the negative of that number to equal zero. The additive inverse of 1 is (-1), the additive inverse of 2 is (-2) and so on.

Example: 5 + (-5) = 0

In this example, (-5) is the additive inverse.

You can then take additive inverse one step when finding the additive inverse when subtracting rational numbers.

Example: 7 - 4 = 7 + (-4)

3 = 3

When finding the inverse, it is important to keep in mind that what you do to one side, you must do the opposite to another. In the example above, because you subtracted a positive four on one side, you are going to add a negative four to the other. This will make the equation equal on both sides.

Which of the following graphs correctly graph y=4^x
(PICS BELOW!!!) (HURRY)

Answers

Answer:

Thus, the 2nd or lower graph represents the graph of  [tex]y\:=\:4^x[/tex].

The correct graph is also attached below.

Step-by-step explanation:

Given the function

[tex]y\:=\:4^x[/tex]

Let us determine the y-intercept by setting x=0, and then determining the corresponding y-value.

now substituting x = 0 in the function

[tex]y=\:4^0\:[/tex]

Apply the rule: [tex]a^0=1,\:a\ne \:0[/tex]

[tex]y = 1[/tex]

Thus, the y-intercept is (0, 1)

Now, if we closely observe the 2nd graph or lower graph, the y-intercept of the lower graph is (0, 1)

Thus, the 2nd or lower graph represents the graph of  [tex]y\:=\:4^x[/tex].

The correct graph is also attached below.

Answers

Answer:

15 ounces per box

Step-by-step explanation:

The rate StartFraction 165 ounces Over 11 boxes EndFraction describes the relationship between the number of boxes and the weight of the crackers in the boxes. What is the weight, in ounces, of one box?

Total weight of crackers in the boxes = 165 ounces

Total number of boxes = 11 boxes

What is the weight, in ounces, of one box?

Weight per box of crackers =

Total weight of crackers in the boxes / Total number of boxes

= 165 ounces / 11 boxes

= 15 ounces per box

The weight, in ounces, of one box is 15 ounces

Amadahy wants to buy a card and two gifts for her friend. Cards cost 3.49 each and gifts cost $10.63 each. Amadahy has a 20$ bill. Does she have enough to buy these items? If so, how much change will she receive? Will she receive? If not, how much more money does she need

Answers

Answer:

Given that Amadahy has a $ 20 bill, and wants to buy a card and two gifts for her friend, and knowing that each card costs $ 3.49 and each gift costs $ 10.63, the total cost of the 3 items would be $ 24.75 (10.63 x 2 + 3.49 ).

Therefore, she will not be able to purchase the products she wants, since she will need $ 4.75 to reach the amount necessary for it (24.75 - 20).

What is a Trigonometric Ratios?

Trigonometric Ratios are ratios of the side of a right angled triangle. These are used to find the missing sides and angles of a right angled triangle.

The step 1 in the table is

sin (2x) = sin (x+x)

The step 3 is

sin (2x) = 2 sine (x) cosine (x)

The step 2 is obtained by the trigonometric identity

sin (x+y) = sinx cosy + cosx siny

So,

sin (x+x) = sinxcosx+sinx cosx

sin (2x) =  sin(x)cos(x) + sin(x)cos(x)
