What is the graph of the function rule? y = 3x - 2 Choose from the pictures

bulgar [2K]

we have

$y=3x-2$

we know that

this is the equation of a line, to identify which is the graph we will proceed to determine the points of intersection with the coordinate axes

1) Find the y-intercept

the y-intercept is when the value of x is equal to zero

For $x=0$

find the value of y

$y=3*0-2$

$y=-2$

2) Find the x-intercept

the x-intercept is when the value of y is equal to zero

For $y=0$

find the value of x

$0=3x-2$

$x=(2/3)$

therefore

the answer is the option B ( see the attached figure)

5x + 2 = 7 X = ? Can you please help me with this

daser333 [38]

Answer:

x=1

Step-by-step explanation:

Move the constant to the right side of the equation and change its sign to the opposite. the constant in this equation is +2. the new equation looks like this: 5x=7-2. After subtracting on the right (7-2) the new equation should be 5x=5. divide both sides of the equation by 5. the answer is x=1

Solve this quadratic equation by completing the square.

nadya68 [22]

Answer:

$x=-3+\sqrt{27}\\ x=-3-\sqrt{27}$

Step-by-step explanation:

Let's find our C value for the quadratic equation.

$(\frac{6}{2})^{2} = 9$

That is our C. Since we added 9 to one side, we have to do the same to the other. We get:

$x^{2} +6x + 9 = 18 + 9\\x^{2} +6x + 9 = 27$

Now, lets form the left side as a binomial squared.

$(x+3)^{2} = 27$

Let's square both sides now:

$x+3 = (+/-)\sqrt{27}$

Now, we subtract 3 from both sides to isolate the variable, X:

$x= -3(+/-)\sqrt{27}$

This means that the answers are:

$x=-3+\sqrt{27}\\ x=-3-\sqrt{27}$

I do not understand your answers though. Answer A makes no sense, answer B is 221, answer C is 115, and answer D also does not make sense. If you could clarify this portion, maybe I can help you find your alphabetic answer
