Answer:
A) y=-4/5
Step-by-step explanation:
When you have two fractions equal to one another, the easiest thing is often to cross multiply. To do this, multiply the top of the left fraction by the bottom of the right fraction, and then multiply the bottom of the left fraction by the top of the right side and put them equal to eachother:
Knowing this, and some algebra, we can solve the question:
(7y+4)(3)=(y+2)(-4)
21y+12=-4y-8
21y+4y=-8-12
25y=-20
y=-4/5
answer for sir is 27 and second is -18
Answer:
y = 2x - 1
Step-by-step explanation:
In an equation with the form y = mx + b, the slope is m. Because parallel lines have the same slope, the slope of the other line is also 2. Plug this back into the mx + b form to get y = 2x - 1.
"Increasing" and "decreasing" are references to what the y-values do when the x-values increase.
Attached is a copy of all four tables, marked with whether the y-values increased or decreased on each step (and it also shows how much that increase or decrease was.
The only table that does this is the top right table in the attachment, which is your second table.
