4x+6y=-12
Make y by itself
6y=-4x-12
y=-2/3x-2
Y intercept: (0,-2)
X-intercept:
0=-2/3x-2
2=-2/3x
x= -3
(-3,0)
Hope that helps
Answer:
4th answer
Step-by-step explanation:
It is the only answer that is able to be represented by a equation.
Lets just say for funzies that "a number" is represented by a variable, say n. We need something that is 15 less than n. This means that subtraction is necessary. The equation representing 15 less than a number is n-15
When you're dividing two exponents with like bases, all you have to do is substract the exponents.
I believe this is 8.<span />
