Mathematics

Natalka [10]3 years ago

Are these simultaneous questions or like seperate ones?

Simultaneous:
4x -3(7x-4) = 12
4x - 21x + 12 = 12
-17x = 0
X = 0

Therefore y = -4

***
If it's a graph
x int: (3,0)
Y int: (0, -4)

Um idk if that's the answers you wanted but I hope it helped somehow??

PLEASE HELP ASAP, I NEED A PERFECT SCORE. I'M IN A STRESS AND PANIC MODE BECAUSE I MAY NOT FINISH 9TH GRADE, PLZ HELP ME ANSWER
grandymaker [24]
M(x) = 5x + 4     n(x) = 6x - 9

Part 1 (m + n)(x) = 5x + 4 + 6x - 9
                           = 11x - 5

Part 2 (m * n)(x) = (5x + 4)(6x - 9) = 30x^2 - 21x - 36

Part 3 m[n(x)] = 5(6x - 9) + 4
                       = 30x - 45 + 4
            = 30x - 41

20 points<br> How on Earth am I supposed to do this
goblinko [34]

Answer: -89

Step-by-step explanation:

So your equation is

- 9(a) - 7(x) - 9(c) - 9(b) - 7(y)

You know that (a) (b) and (c) = -1

You also know that (x) and (y) = 7

So, when you put this into the equation, it will look like this:

- 9(-1) - 7(7) - 9(-1) - 9(-1) - 7(7)

When you work that out you will get left with your answer, which is -89.

HOPE THIS HELPS!!!
