Solve 2x - y = -6 if the domain is (-2,-1, 0, 1).

MAVERICK [17]

Answer:

y = 2, y = 4, y = 6, y = 8

Step-by-step explanation:

We are given an equation 2x - y = - 6.

We have to solve it.

The linear two-variable equation can be rearranged as y = 2x + 6 ........ (1)

Now, we need x values to get corresponding y values.{Since, there are two variables and only one equation}

It is given that the domain is (- 2, - 1, 0, 1).

Therefore, those are the x values for which we have to solve for y from equation (1).

For, x = - 2, y = 2( - 2 ) + 6 = 2 (Answer)

For, x = - 1, y = 2( - 1 ) + 6 = 4 (Answer)

For, x = 0, y = 2( 0 ) + 6 = 6 (Answer)

For, x = 1, y = 2( 1 ) + 6 = 8 (Answer)

Simplify (-5/7)÷(-1/2) show work

anastassius [24]

Answer:

$\frac{10}{7} \: or \: 1 \frac{3}{7}$

Step-by-step explanation:

$- \frac{5}{7} \div - \frac{1}{2} = - \frac{5}{7} \times - \frac{2}{1}$

First you reciprocate the fractions and change the division sign to multiplication.

$- 5 \times - 2 = 10 \: and \: 7 \times 1 = 7$

Therefore the answer is:

$\frac{10}{7}$

What is the completely factored form of x^4+8x^2-9

denis-greek [22]

Remark

You'll see it a whole lot easier if you make a substitution so that it looks like something you have already seen

Solution

let y = x^2

x^4 = x^2 * x^2

x^4 = y * y

x^4 = y^2

Now the expression becomes

y^2 + 8 y - 9 = z

(y + 9)(y - 1) = z

Now put the x^2 back in.

(x^2 + 9) ( x^2 - 1) = z

x^2 - 1 becomes x + 1 and x - 1. At this level x^2 + 9 can't be factored.

Answer

(x^2 + 9) (x + 1)(x - 1)

HOW TO WRITE IN DIVISION EXXPRESION I GIVE BRAINLEST

Rufina [12.5K]

Answer:

I believe that 4 1/2 divided by 6 is the correct answer.

(It is the same as the expression you wrote next to "Regular." It is correct because it does not include an equal sign and correctly expresses the problem.)

Note: Do not include any work below the arrow when writing in the "Expression" section.

Please let me know if this is incorrect.
