3x + 4 = 13 by adding -4 to both sides of the equation we say that +4 and -4 on the left side of this equation ? each other out. algebra

Complex numbers multiply √-4 * √-25 and show all intermediate steps. alternative notation is sqrt(-4) * sqrt(-25).

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
