Answer:

x < -3\frac{3}{4}

Step-by-step explanation:

Given

-6x+22\frac{1}{4}+2x > 9\frac{3}{4} +16\frac{1}{2}

Required

Solve for x

-6x+22\frac{1}{4}+2x > 9\frac{3}{4} +16\frac{1}{2}

Collect Like Terms

-6x+2x > 9\frac{3}{4} +16\frac{1}{2}-22\frac{1}{4}

-4x > 9\frac{3}{4} +16\frac{1}{2}-22\frac{1}{4}

Convert all fractions to improper fractions

-4x > \frac{39}{4} +\frac{33}{2}-\frac{45}{4}

Take LCM

-4x > \frac{39+66- 45}{4}

-4x > \frac{60}{4}

-4x > 15

Divide through by -4; When an inequality is divided by a negative number, the inequality changes.

\frac{-4x}{-4} < \frac{15}{-4}

x < \frac{15}{-4}

x < -\frac{15}{4}

Convert to improper fraction

x < -3\frac{3}{4}

Which pair of functions are inverses of each other?
klio [65]

f(x) = 10x -5 and g(x) = (x+5)/10  are inverses of each other , Option D is the correct answer.

<h3>What is a Function ?</h3>

A function is a mathematical statement which relates two variables , a dependent and an independent variable.

The inverse of a function is found by replacing every y by x and vice versa , and then solve for y

The equation

f(x) = 4/x - 3

or

y= 4/x -3

Replacing y by x

x = 4/y -3

x +3 = 4/y

y = 4/(x+3)

Which do not correlate with the given inverse

f(x) = 10x -5

y = 10x -5

for finding inverse

10y -5 = x

10y = x+5

y = (x+5)/10

g(x) = (x+5)/10

Therefore , Option D is the correct answer.

A football stadium splits ticket sales in ratio of 3 : 4 between the away team and the home team. The home team make £36,000. Wh
Naddika [18.5K]
<h3>Answer is 63,000 pounds</h3>

The ratio 3:4 means for every 3 pounds made in away team tickets versus home team tickets. Multiply both sides by 9000 to have that 4 turn into 36000. The ratio 3:4 will then turn into 27000:36000

With this new ratio, we see that the away team pulls in 27000 and the home team pulls in 36000. Add the two amounts to get the final answer

27000+36000 = 63000

------------

We could alternatively add 3 and 4 (from the ratio 3:4) to get 3+4 = 7. Then multiply by that same scale factor 9000 getting 9000*7 = 63000.
