Mathematics

Answer:

x = 6 and x = -1.

Step-by-step explanation:

The given equation is :

6x^2-30x=36\\\\6x^2-30x-36=0\\\\or\\\\x^2-5x-6=0

We can solve it using the middle term splitting method.

x^2-(6x-x)-6=0\\\\x^2-6x+x-6=0\\\\x(x-6)+1(x-6)=0\\\\(x-6)=0\ and\ (x+1)=0\\\\x=6\ and\ x=-1

So, the solutions are x = 6 and x = -1.

Answer:

It'd be C?

Step-by-step explanation:

Well, if you turn 5/2 into a mixed number, it will be 2 1/2, and if you add 2 1/2 to 3, it would be 5 1/2, and C is the only one that shows it. Not only that, you could probably find out with common sense, because there is no subtracting in this problem, but every other answer besides C is subtracting.

Hope this helps

Bit late though lol

Y=-4x-7, x+y=2 please help rn
Mashcka [7]
Use substitution
x -4x - 7 = 2
-3x = 9, x = -3
Y = -4(-3) - 7
Y = 12 - 7, y = 5
Solution: x = -3, y = 5

Y=1/2×-6 ×=-4 what is the solution to the system of equations
hodyreva [135]

Answer:

(-4, -8)

Step-by-step explanation:

Use the substitution method.  x = -4, so y = (1/2)x - 6 becomes:

y = (1/2)(-4) - 6, or y = -2 - 6, or y = -8.

The solution is (-4, -8).
