I hope this helps, pls tell me if my way of answering is wrong
Answer:
2x-3y=4
x-2y=4
The minimum number of times would be 5 times.
15^2 + 36^2 = 39^2
Your answer is 39
1.1 Solve y-12x+7 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-12x+7 = 0 and calculate its properties
According to: https://www.tiger-algebra.com/drill/y=12x-7/
im not sure about the first one but im 100% about 2 and 3
2-A
3-D
