Answer:
See below.
Step-by-step explanation:
It can really help to think when you see |expression| that it means the distance from expression to zero.
(a) |x| < 7 means the distance from x to 0 is less than 7. That puts x between -7 and 7. The solution set is -7 < x < 7.
(b) |x + 3| < 9 means that the distance from x + 3 to 0 is less than 9. That puts x + 3 between -9 and 9:
-9 < x + 3 < 9 Now subtract 3 from all three parts.
-12 < x < 6
(c) |y - 8| > 11 means that the distance from y - 8 to 0 is more than 11 units. That puts y - 8 in one of two places: left of -11 or right of 11.
(g) 
means that the distance from 3x - 1 to 0 is more than (or equal to) 18. Another way to say it is, 3x - 1 is farther from 0 than 18 units. That puts 3x - 1 in one of two places: to the left of -18 or to the right of 18.
means that 4y + 3 is closer to 0 than 13; it is between -13 and 13.
(That last fraction is 10/4 simplified.)
Answer:
35x^2 is a polynomial because it is a whole # and x is the product of the term, it also has a variable.
the other answer is x/5+2
Answer:
1.45 as a fraction is 29/20
Step-by-step explanation:
Answer:
$1605
Step-by-step explanation:
Because this is simple interest, you can convert the 7% into a decimal
Because she payed an EXTRA 7% she payed 107% total
107% is the equivalent to 1.07
By multiplying 1500 x 1.07 = 1605
