A system of equations is given below.
y=-3x+6 and Y = 6-3x
Which of the following statements best describes the two lines?
O They have different slopes and different y-intercepts, so they have no solutio
They have different slopes and different y-intercepts, so they have one soluti
They have the same slope and the same y-intercept, so they have no solutio
TO They have the same slope and the same y-intercept, so they have infinitelyn

answer: 1 and 3

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
