Answer:
4
Step-by-step explanation:
2x+y=12
y=-2x+12
y-2=3(x-2)
If it’s parallel to each other: the slope has to be the same.
If is perpendicular to each other: the slope should be the reciprocal to each other.
The first equation has a slope of -2
The second has a slope of 3
Neither the condition meet. So the answer is 4
Answer:
a=20
Step-by-step explanation:
4a+8-2a-3=45

Answer:
x: 12 9 6 3
y: 11 8 5 2
Step-by-step explanation:
Every box is the previous number minus 3. For x, they say to start with 15 and subtract 3, so the first box is 15-3. The second box is the previous box, 12, minus 3 and so on. Y is done the same way. Hope this is helpful :)
