Percent is simply /100, so the fraction would be 450/100. Divide both top and bottom and you will get 9/2, or 4 1/2
This problem could be set up algebraically or you could use trial and error.
a) 9 and 4 (9 + 4 = 13, 9 * 4 = 36 and 36 - 23 = 13)
I won't give you the rest of the answers, but the second and third ones have to add together to equal a negative number and multiply to equal a positive number. I hope this helps some.
Slope is change in y over change in x.
Change in y is -9
Change in x is +12
So -9/12 or -2/3
Answer -2/3
An equation can be determined as linear if it is first order in a single variable, i.e. y=3x, but not y=3x^2.
A graph will be linear if the slope is constant
Let's solve for i.
z=−12i+11
Step 1: Flip the equation.
−12i+11=z
Step 2: Add -11 to both sides.
−12i+11+−11=z+−11
−12i=z−11
Step 3: Divide both sides by -12.
−12i−12=z−11−12
i=−112z+1112
Answer:
i=−112z+1112
