Answer:

y = 3x - 10

Step-by-step explanation:

I'm assuming that you are supposed to write the equation of a line that is parallel to the one given, going through the point given. I'm going with that. This is a line in slope-intercept form: y = mx + b.

If 2 lines are parallel to one another, the m values are exactly the same. So what we need to do is find the y-intercept value, b, since that is what is different in parallel lines. We will use the m value of 3, the x value from our point of 2, and the y value from our point of -4 to solve for b:

-4 = 3(2) + b and

-4 = 6 + b so

b = -10. Now we fit that back into the equation using the same m value as in the line it is parallel to:

y = 3x - 10

$\begin{gathered} -2(x+4)(3x-18)=0 \\ \text{There are two factors here which are} \\ -2(x+4)\text{ and} \\ (3x-18) \\ \text{This means, either} \\ 2(x+4)=0 \\ 2x+8=0 \\ 2x=-8 \\ \text{Divide both sides by 2} \\ x=-4 \\ OR \\ 3x-18=0 \\ 3x=18 \\ \text{Divide both sides by 3} \\ x=6 \\ \text{Therefore,} \\ x=-4\text{ or} \\ x=6 \end{gathered}$

x = -4 OR x = 6

The correct options are B and G

3q(p-q)+2r(p-q)-S(q-p)<br> Can u solve it step by step

Artyom0805 [142]

Answer:

-3q² + 3qp + 2rp - 2rq + Sq - Sp

Step-by-step explanation:

first part

3q(p-q) = 3qp - 3q²

second part

2r(p-q) = 2rp - 2rq

third part

S(q-p) = Sq - Sp

then we put it all together

3qp - 3q² + 2rp - 2rq + Sq - Sp

in the right place possibly

-3q² + 3qp + 2rp - 2rq + Sq - Sp

Solve for x:

777dan777 [17]

Answer:

Step-by-step explanation:

x^2+120=0 can be rewritten as x^2 = - 120. Taking the square root of both sides, we get x = plus or minus i*√120 = plus or minus i*√4√30, or

x = plus or minus i*2√30

So the correct answer choice here is "None of the above."

King cobras can grow to be more than 4 Meters long how long is this in feet

Aliun [14]

To figure out how long a king cobra is in feet, you need to find how much 1 meter is in feet.

1 meter is 3.28084 feet. So you need to multiply 3.28084 feet (equals 1 meter) by 4 meters.

A king cobra is 13.1234 feet.
