The point (1, 4) is translated so it ends on the coordinates (-2, 2). Which of the following describes the translation?
Rom4ik [11]

Answer:

The first answer choice is the correct one.

Step-by-step explanation:

Going from (1, 4) and ending up at (-2, 2), we see that the original point is now 3 units to the left of its starting position, and 2 units down.

Clarification:  from x = 1 to x = -2 is 3 units (to the left), and

                       from y = 4 to y = 2 is 2 units (down)

The first answer choice is the correct one.

When you subtract a number, you get the same results as when you add the opposite number. Why?
lapo4ka [179]

Answer:

Step-by-step explanation:

Well, the opposite of a number is the same number with the opposite sign. For example, the opposite of -1 is 1.

So, say we have an equation where we're subtracting a number, for example, 2-1, which obviously equals 1. Now, if we add the opposite of 1 to 2, we get the equation 2+(-1) which still equals 1.

I hope this helps!

Raul is paid $75 per week plus $5 for each new gym membership he sells. He may switch to a gym that pays $50 per week and $7.50
rosijanka [135]
Answer:
11 memberships

Step-by-step:
Gym 1 = 75+5m
Gym 2 = 50+7.5m

75+5m=50+7.5m
-50 from both sides
25+5m=7.5m
-5m from both sides
25=2.5m
divide both sides by 2.5
10=m
for 10therefor 75+5m<50+7.5m he must sell 11 memberships.
