Need help ASAP! ΔABC was dilated from the origin by a scale factor of 2 to create ΔA′B′C′. Which statement explains why the triangles are similar? Dilations preserve side length; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve betweenness of points; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve orientation; therefore, the corresponding angles of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve angle measure; therefore the corresponding angles of ΔABC and ΔA′B′C′ are congruent.

Suppose your school costs for this term were $4900 and financial aid covered 3/4 of that amount. how much did financial aid cover? and how much do you still have to pay?

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
