Y = ax + b;
0.89 = a * 2 + b and 2.09 = a * 5 + b =>
=> 2.09 - 0.89 = a * 5 + a * 2 + b - b => 1.20 = 3 * a => a = 1.20 / 3 => a = 0.40;
b = 0.89 - 0.40 * 2 => b = 0.89 - 0.80 => b = 0.09;
y = 0.40x + 0.09 => 0.40x - y + 0.09 = 0 is the linear equation.
Thus half of 14 is: 7
Division sentence: 14 ÷ 2 = 7
<span>100 textbooks increased by 99%
Do this:
First, make 99% a decimal, to do this, you must divide 99 by 100
you get 0.99
multiply 0.99 by 100
you get 99
then, add 99 to 100 and you get 199
so the total sum is 199!!
Hope this helped!
