Answer:

x= -0.66+0.33

Step-by-step explanation:

you already have what y equals, so the next step is to plug in the solution for y into  6x - 2y = - 4

-plug in y = 3x + 2 into 6x - 2y = - 4 through the y variable

-making the equation now 6x - 2(3x + 2) = - 4

-now solve for x by distributing -2 to 3x and +2

6x - 6x - 4 = - 4 ------> - 4 = - 4

6x - 2y = - 4 -----> 6x = - 4 + 2y -----> x = - 0.66 + 0.33

Answer:

Step-by-step explanation:

6x - 2y = -4

y= 3x + 2

We see that y = 3x + 2 so we can use that value of Y everytime we see i in the other equation.

6x - 2(3x +2) = -4

Now usually we'd we simply solve for X.

6x - 6x -4 = -4

This clearly does not work as we cannot get rid of X

Therefore, this system of equations has no solution we can find through substitution

A gallon of Moo Milk cost $5.12. What is the price, in dollars, of an 8 oz glassof Moo Milk?
MA_775_DIABLO [31]
The cost for a gallon of Moo Milk is $5.12
To find the cost of 8 fl. oz. of Moo Milk, the unit price must be found.

Therefore:

One gallon of liquid equals 128 fluid ounces. 

5.12 ÷ 128 = 0.04

0.04 × 8 = 0.32

Therefore, the cost of 8 fluid ounces of Moo Milk is $0.032 

I hope this helped - Maria S.

verbally explain how to obtain the graph of the quadratic function f(x)=-2(x+3)^2-4 from the graph of y=x^2.
Ksivusya [100]

Answer:

The graph f(x)=-2(x+3)^2-4 is a reflection over the x-axis, vertical stretch by a factor of 2, a horizontal translation left 3 units and a vertical translation 4 units down of the graph y=x^2.

Step-by-step explanation:

The graph f(x) is reflected over the x-axis because the negative is outside of the parenthesis.

it's a vertical stretch by a factor of 2 because 2 is outside of the parenthesis and is greater than 1.

(x+3) is a horizontal translation left 3 units because it is inside the parenthesis.

-4 is vertical translation 4 units down because it is outside of the parenthesis.
