Hello Guys, I really need help with these questions. Here they are.
Slav-nsk [51]

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.

y-8 < -11 \text{ or } y-8 > 11\\\\y < -3 \text{ or } y > 19

(g)  |3x-1| \ge 18 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.

3x-1  \le -18 \text{ or } 3x-1 \ge 18\\\\3x \le -17 \text{ or } 3x \ge 19\\\\x \le -\frac{17}{3} \text{ or } x \ge \frac{19}{3}

|4y+3| \le 13  means that 4y + 3 is closer to 0 than 13;  it is between -13 and 13.

-13 \le 4y+3 \le 13\\\\-16 \le 4y \le 10\\\\-4 \le y \le \frac{5}{2}

(That last fraction is 10/4 simplified.)

Jose, baulus, and George are having a disagreement over interest rates. Jose says that 6 3/4% can be expressed as 6.75%. George
otez555 [7]

Answer:

Jose and George are correct

Baulus is incorrect

Step-by-step explanation:

Given

6\frac{3}{4}%

Required

Compare the above expression with

Jose: 6.75%.

George: 0.0675

Baulus: 0.0675%

<em>The expression </em>6\frac{3}{4}<em>% is given as a mixed fraction;</em>

In Jose's case, he simply converted it to decimal

Converting 6\frac{3}{4}% to decimal;

First, we need to convert to improper fraction

6\frac{3}{4}% in improper fraction is \frac{27}{4}%

Then, we divide the numerator by the denominator

\frac{27}{4}% = 6.75%.

Hence, Jose is correct

In George's case, he solved further by removing the % from Jose's answer.

% means divided by 100; In other words, x% means that we divide x by 100

So, 6.75% means we divide 6.75 by 100

\frac{6.75}{100} = 0.0675

Hence, George is also correct

But same can't be said of Baulus;

Baulus converted 6\frac{3}{4}% as 0.0675%

This means that he converted 6\frac{3}{4} as 0.0675 then he appended it with the percentage sign (%)

Since 6\frac{3}{4} is not equal to 0.0675, then we can conclude that Baulus is incorrect
