Answer:
1) rate = 175 miles/4 hours, unit rate = 43 3/4 miles/hour
5) y = 2x + 2
Also I think you made a mistake for #2, read explanation please.
Step-by-step explanation:
1) 175 / 4 = 43 3/4 miles/hour.
5) y = 2x + 2, We know that 2 is added since 0 x 2 =/= 2.
2) (Referring to 12^0) When you raise a number to the power of 0 the result is always 1, but if it's negative then the result would be -1 instead.
Expanded form and standard form are both 1, since the base 12 is positive.
