Aline is drawn on a scatter plot, as shown below:
which statement best describes the line?
it can be the line of best fit because it closely fits the data points.
it can be the line of best fit because it is passes through all the data points.
it cannot be the line of best fit because it shows a negative linear association.
it cannot be the line of best fit because it does not pass through all the data points.
the solutions are -8, -3
we are given an equation z² + 11z + 24 = 0 and we have to find solutions for it, which means finding out the value of z.
we will do it by factorization method
we will factorize the equation such that the sum of two factor is equal to 11z and the product is 24z²
z² +8z + 3z + 24 = 0
z(z + 8) + 3(z + 8) = 0
taking z+8 common above
(z+3)(z+8) = 0
z+3 = 0, z = -3
z+8 = 0, z = -8
so the solutions are -8, -3
given the radical form:
use the exponent rules:
we can write as:
therefore, in exponential form is
