Answer:
5 + 14 and 12 + 7
Step-by-step explanation:
Answer: 200
Step-by-step explanation: all you have to is multiply 50 by 4 because 25 is a forth of 100% and 50 x 4 = 200.
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/
Factorise x^2+6x+8=0 to get (x+4)(x+2)=0
Solve to get x=-4, x=-2
Factorise x^2+6x+13=0 (I assumed you mistyped and wrote * instead of +)
Use the quadratic formula and you find that there are no real roots so the answer for this is just x=-4, x=-2
Tell me if I made any mistakes
