Answer: (-9,6)
Step-by-step explanation:
3x+2y=-15
2x=-18
First solve for x in second equation
2x=-18
2x/2=-18/2
X= -9
Now substitute your x into first equation to find y
3(-9)+2y= -15
-27+2y=-15
2y= -15+27
2y= 12
2y/2=12/2
Y= 6
Answer:
The answer is 14
Step-by-step explanation:
14x2=28
14x3=42 so the greatest common factor is 14
Y=-3x+4
Gradient, m= -3
Parallel lines have equal gradients;
So, equation II,
y=mx+c
y=-3x+c
Replacing for x and y using point (-4, 6)
6=-3(-4)+c
6=12+c
6-12=c
c=-6
y=-3x-6
Answer:
Choice 2
Step-by-step explanation:
Range is talking about the y value of the coordinates. Choice 2 has all the y value in the function
I dont know if those lines were suppose to be there, but i put 0.63 in simplest form = 63/100
