Work out -4x-3+2x-6 can I have help please ?

Answers

Let's reorder the equation. -4x+2x-3-6. Now we can reduce like terms. -4x+2x= -2x and -3-6= -9. Put the two back together and it is simplified to -2x-9.
-4x-3+2x-6-4x+2x-6-3-2x-9I hope that is good!

What is an increasing or decreasing interval of a parabola? Is it like the vertex or turning point of the parabola? I don't remember. :(

Answers

Well first, an interval is a set of real numbers, usually x values. For example 0 ≤ x ≤ 1 is an interval. If the y values for the x values of the set increase as the x values increase, then the interval is increasing. If the y values for the x values of the set decrease as the x values increase, then the interval is decreasing. I hope that wasn't confusing, if you have questions, ask.

Use a transformation to solve the equation. k/-4 = - 0.8












A.

k = –3.2








B.

k = –0.2








C.

k = 0.2








D.

k = 3.2

Answers

k/-4 = - 0.8,
make k the subject of the equation by multiplying through by -4,
   this means, (k/-4) x -4 = - 0.8 x -4
     this should give you k = -0.8 x -4, the negatives will cancel out to give you positive values,
                               so k= 3.2

your answer is D
