5x + y = 21x - 3y = 9First, find the lowest common multiple for x or y and make the equations equal for either x or y.Here, we multiply the second equation by 5 to make the amount of x the same. The equat...

In Spanish we change the endings of verbs to show who is doing the action. Each verb has a stem and for regular verbs this never changes. To conjugate (form) a verb in the present tense we take the infini...

In this question we are looking to find a value by substitution. In this case we are substituting the integer (-2) into the equation in place of the x which would be illustrated as f(-2)= 4(-2)^3+12. It i...

First identify the part of the sentence in which the answer is. This will be from 'ut' to 'interficerent', since the question 'in what way were Nisus and Euryalus cruel?' is practically a translation of '...

First find a root of the function: f(x)=x^3+2x^2-5x-6 f(2)=(2)^3+2*(2)^2-5*(2)-6 =0. Therefore, (x-2)(x^2+Ax+3)=0 where A is an unkown constant. Compare x^2 coeffecients: A-2=2, A=4. So (x-2)(x^2+4x+3)=0....
