Answer:
its either ratio or unit rate.
Step-by-step explanation:
which sequences are arithmetic? check all that apply. –8.6, –5.0, –1.4, 2.2, 5.8, … 2, –2.2, 2.42, –2.662, 2.9282, … 5, 1, –3, –

In an arithmetic sequence, the next term is found by adding a constant term to each number to arrive at the next number. The common difference can be found by subtracting the first term from the second term.
-8.6, -5.0, -1.4, 2.2, 5.8....the common difference here is 3.6
-8.6 + 3.6 = -5.0
-5.0 + 3.6 = -1.4
1.4 + 3.6 = 2.2
2.2 + 3.6 = 5.8
so this IS an arithmetic sequence.
2,-2.2, 2.42, -2.662, 2.9282...there is no common difference..so this is not an arithmetic sequence
5,1,-3,-7,-11....common difference is -4
5 + (-4) = 1
1 + (-4) = -3
-3 + (-4) = -7
-7 + (-4) = -11
this IS an arithmetic sequence
-3,3,9,15,21...common difference is 6
-3 + 6 = 3
3 + 6 = 9
9 + 6 = 15
15 + 6 = 21
this IS an arithmetic sequence
-6.2, -3.1, -1.55, -0.775, -0.3875...this is not an arithmetic sequence
Answer:
x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.75x+3=6(x−3)
0.75x+3=(6)(x)+(6)(−3)(Distribute)
0.75x+3=6x+−18
0.75x+3=6x−18
Step 2: Subtract 6x from both sides.
0.75x+3−6x=6x−18−6x
−5.25x+3=−18
Step 3: Subtract 3 from both sides.
−5.25x+3−3=−18−3
−5.25x=−21
Step 4: Divide both sides by -5.25.
−5.25x/-5.25 = -21/-5.25
Answer: x=4
The answer would be 1,000,000 times
