Step 1: Subtract 3x from both sides.
−x+7=−52
Step 2: Subtract 7 from both sides.<span><span><span><span>

Okay, so you are talking about exponents, so what you are talking about is 2², to find the answer to the exponent you multiply the same number as many times as the exponent (little number) says, so in here we are going to multiply 2 x 2 and the answer is 4. So 2 to the power of 2 is 4.
#420
because 70x4=420 within 300 and 500 and is greater than 400 which is a multiple of 100
To move a graph up c units, add c to the whole function
so basicaly what you did is you subtraced 3 from the whole function
the whole graph shifts 3 units down
B is answer
