If y = -x and x + 6y = 30, what is the<br> value of x?
jekas [21]

Answer:

x = -6

Step-by-step explanation:

y = -x  equation 1

x + 6y = 30   equation 2

using equation 1 in equation 2 we have:

x + 6(-x) = 30

x - 6x =30

-5x = 30

x= -30/5

x= -6

solve the inequality algebraically. express your answer using interval or set notation. graph the solution set. -5 less than or
Bumek [7]

Step-by-step explanation:

This ≤ inequality sign means:

  • Less than/Equal to
  • No more than
  • At most
  • Maximum of

-5 ≤ 4

And then:

-3x ≤ 2

OR:

-5 ≤ 4 -3x ≤ 2

Hi!!! Sorry, I didn't know if they were suppose to be together or separate, so I just did it both ways!!! :) Really sorry if I am wrong...

Eira created color panels for a wall using a mix of only red and blue paints. She plotted the quantities of red and blue paints
lesya [120]

Answer:

3 ≤ x ≤ 7 or x is between 3 and 7, inclusive

Step-by-step explanation:

Eira's graph probably resembled the diagram below.

The domain is the set of all possible x-values that will make a function work.

x can take any value from 3 to 7.

The domain is [3, 7] or 3 ≤ x ≤ 7.

Choose the equation that satisfies the data in the table.
KengaRu [80]

The equation that satisfies the data in the table is,

y = -4x - 4 [Option D]

Definition of an Equation:

An equation is defined as a mathematical assertion in which you use mathematical symbols to demonstrate the equality of two amounts. A combination of expressions with variables and constants on either side of the equality sign make up an equation.

The (x, y) coordinates from the given table are,

(-1,0), (0, -4), (1, -8)

Now, these points must satisfy the required equation.

Considering the first point (-1, 0), if we substitute these values of x and y coordinates in y=4x-4, the equality is no longer maintained.

Similarly, (-1,0) does not satisfy the second and third equations, that are, y = -x + 4 and y = x + 4, respectively, either.

Taking the fourth equation, y = -4x - 4

Putting x = -1 in this equation, we get,

y = -4(-1) - 4

y = 4 - 4

y = 0

Likewise, this equation satisfies the rest of the data in the table too.

Therefore, y = -4x - 4 is the required equation.

If y is less than or equal to minus 4x and 3x minus 4 is equal to 2x plus 6. find the value of x​
MrRa [10]

Answer:

y <= -40

Step-by-step explanation:

3x-4 = 2x +6 --->

3x-2x = 6+4 ---->

x  = 10 --->

y <= -4 times  10--->

y <= 40
