Answer:
2 < x
Step-by-step explanation:
7-2(x + 2) <-4 - 3(1 - x)
Distribute
7 - 2x-4 < -4 -3 +3x
Combine like terms
3 -2x < -7+3x
Add 2x to each side
3 -2x+2x< -7+3x+2x
3 < -7+5x
Add 7 to each side
3+7 < -7+7+5x
10 < 5x
Divide each side by 5
10/ 5 < 5x/5
2 < x
Answer: 3. 26
Step-by-step explanation:
Answer:
Part 1) Is not a valid code
Part 2) The last digit should be 6 in order to make it a valid code
Step-by-step explanation:
we have
2-81273-05213-8
we know that
The last number is the check digit (8)
<em>Verify the UPC number</em>
step 1
Sum the digits in the odd positions, starting at the left
so
2+1+7+0+2+3=15
step 2
Multiply the answer in step 1 by 3
15(3)=45
step 3
Sum the numbers in the even positions, ignoring the last (12th) digit because that is the check digit that you are verifying
Do not multiply this number by 3.
8+2+3+5+1=19
step 4
Add the results from steps 2 and 3
45+19=64
step 5
Subtract the number in step 4 from the next higher multiple of 10. In this example, the next multiple of 10 after 64 is 70, so subtract 64 from 70:
70-64=6
This number is not equal to the check digit (8)
therefore
Is not a valid code
The last digit should be 6 in order to make it a valid code
The answer is -60. this is because the signs implemented in front of numbers give it a sort pattern .
when there are two additions the last number after the positive sign will give a positive number 1 greater than the initial number for example + 5 + 6. Answer afterward will be + 7 and for negative sign eg: - 7 - 8 in the question will give the answer -8 the same number after a negative (-) sign .
Hope this helps
Answer:
A if 
B if y=3(2)x
Step-by-step explanation:
To find the table, input x values into the equation and solve for y:
- If the equation is y=3(2)x then table B is the solution.
For x=0, y = 3(2)(0) = 0.
- If the equation is then table A is the solution.
For x=2, 
.
For x=1, 
.
For x=0, 
.
