Solve the “and” compound inequality for –1 < 6x + 1 ≤ 13
ser-zykov [4K]

Answer:

-1/3 < x <(or equal to) 2

Step-by-step explanation:

Firstly divide your inequality into two separate inequalities...

1) -1 < 6x + 1...then solve for the first one..,which then gives you....;

-2 < 6x....which gives us our first solution (x > -1/3)

Then the second inequality

2) 6x + 1 <(or equal to) 13

which then gives you....,

6x <(or equal to) 12...which then gives our second solution...( x <(or equal to) 2)

Then combine the two solutions into a compound solution

-1/3 < x <(or equal to) 2

carey is trying to decide between two guitars. the first had an original price of $160, but is on sale for $100. the second had
MrMuchimi
To determine the percent change in price, solve for the differences between the original prices and the sale prices. Then, divide the difference by the original price and multiply by 100%.

Guitar 1:       (($160 - $100) / $160) x 100% = 37.5%
Guitar 2:       (($250 - $150) / $250) x 100% = 40%

Thus, guitar 2 has a greater percent change in price.

Which equation shows how to find the product of 100,000 and 1,000,000 using scientific notation?
Drupady [299]
Your answer is B 100,000 × 1,000,000 = (1 × 10^5) × (1 × 10^6) = 1 × 10^(5 × 6) = 1 × 10^30 because...

100,000=1×10^5
1,000,000=1×10^6

And 5×6=30

Also its not A because 5×6=30 not 11 its not C because 5×6=30 not 13 and when it came down to rather B or D I choose Because once again 5×6=30 no 42.


Basically all of the options are worded correctly but their they didn't multiply it the same at the end which is 5×6


Your answer is B.
