There are many ways a problem can be simplified. You can divide by the GCF (Greatest Common Factor) or even factor which depending on where you are in math you may or may not have learned. For your problem, I will use the first method.
3m-8 can be multiplied by any term (keep it simple):
2(3m-8) = 6m-16
4(3m-8) = 12m-32
Your answers should be 6m-16 and 12m-32.
Denominator, 12 and 9 are on the bottom. and 15 and x are on the right side.
Answer:
y= -2x-3
Step-by-step explanation:
Using the slope intercept form we have to first find the gradient of the line.
m=(y₂-y₁)/(x₂-x₁)
y₁=5
y₂=-9
x₁=-4
x₂=3
Therefore, m= (-9-5)/(3--4)
=-2
Therefore if we pick any point on the line, say, (-4,5) we obtain the same slope.
(y-5)/(x--4)=-2
(y-5)/(x+4)=-2
y-5=-2(x+4)
y-5=-2x-8
y= -2x-3
Thus the equation of the line in the slope intercept form is: y= -2x-3
Answer:
2 lines
Step-by-step explanation:
You're close. The only one missing is the intersection of 3 planes can be 2 lines if 2 of the planes are parallel.
