Answer: B, C, E
-------
The difference between consecutive terms (numbers that come after each other) in arithmetic sequences is the same. That means you add the same number every time to get the next number. To figure out which choices are arithmetic sequences, just see if the differences are the same.
Choice A) 1, -2, 3, -4, 5, ...
-2 - 1 = -3
3 - (-2) = 5
The difference is not constant, so it is not an arithmetic sequence.
Choice B) 12,345, 12,346, 12,347, 12,348, 12,349, ...
12,346 - 12,345 = 1
12,347 - 12,346 = 1
The difference is constant, so it is an arithmetic sequence.
Choice C) <span>154, 171, 188, 205, 222, ...
171 - 154 = 17
188 - 171 = 17
The difference is constant, so it is an arithmetic sequence.
Choice D) </span><span>1, 8, 16, 24, 32, ...
8 - 1 = 7
16 - 8 = 8
</span>The difference is not constant, so it is not an arithmetic sequence.
Choice E) <span>-3, -10, -17, -24, -31, ...
-10 - (-3) = -7
-17 - (-10) = -7
</span>The difference is constant, so it is an arithmetic sequence.
Answer:
x = -6
Step-by-step explanation:
That's it. That's the vertical line through (-6, 6).
Literally just the x-coordinate (because it will be parallel to the y-axis, draw it out on a paper if confusion).
Answer:
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced problems.
The Pet-agree company is buying the collars at $1.19. They then have to increase the price in order to make a profit. They decide to mark it up 356% of the cost they paid. In order to calculate the Selling Price we need to first convert the percent into a decimal. We can do this by moving the decimal point two digits to the left.
356.00% ⇔ 3.56
Now we can multiply the decimal by the original cost of the collar.
$1.19 × 3.56 = $4.236
Rounded up the Selling price of the collar would be $4.24. But the question asks us for the amount of the mark up, so we need to subtract the selling price from the buying price.
$1.19 - $4.24 = $3.05
The amount of mark-up from the original price is a $3.05 difference.
