Firstly we must count the values between each of the terms to find the first differences. (EG- 26-11=15, 1st differences: 15,19,23)Next we need to count the values between each of the first differences to...

x = -2 x = -2/3

In order to get p on its own, it is necessary to move it over to the right hand side of the equation. When moving something from one side to another, you flip the sign. For example, in this case, it is 8*...

Two equations 1) 5x + y = 21, 2) x - 3y = 9. Eliminate x or y by manipulating equations 1 or 2. Equation 3 = equation 2 x 5 = 5(x-3y) = 5(9) 3) 5x - 15y = 45. Equations 3 & 1 both have 5x's so we can ...

f(-2) = 3(-2) + (-2)² = -6 + 4 = 2First you need to substitute -2 for each value of x in the function. Then you need to simplify the expression by multiplying -2 by 3 and by squaring -2. (Hint...
