This is something you call "Proportions" or two ratios equal to each other.

$\frac{7}{8}= \frac{z}{32}$

Multiply 32 and 7.

$\frac{224}{8} = z$

The answer is $z = \frac{224}{8}$ or $28$

Answer: $x^2-8+\dfrac{4x+5}{x^4-3x^2+4x+5}$

Step-by-step explanation:

P(x) = x⁴ - 3x² + 4x + 5

g(x) = x² + 5

_x²_- 8

x² + 5) x⁴ + 0x³ - 3x² + 4x + 5

-(x⁴ + 0x³ + 5x²) ↓ ↓

-8x² + 4x + 5

-(-8x² + 0x - 40)

4x + 45

$\dfrac{x^4-3x^2+4x+5}{x^2+5}=\large\boxed{x^2-8+\dfrac{4x+5}{x^4-3x^2+4x+5}}$

Answer:

Required inequality is $4800+183x>8000$ .

Step-by-step explanation:

Given that Mrs. Robinson, an insurance agent, earns a salary of $4,800 per year plus a 3% commission on her sales. The average price of a policy she sells is $6,100. Write an inequality to find how many policies Mrs. Robinson must sell to make an annual income of at least $8,000.

Calculation is given by:

Salary per year = $4,800

Average price of a policy = $6,100.

commission on her sales = 3%

Then commission on $6,100 = 3% of $6,100 = 0.03 ($6,100) = $183

Let number of policies Mrs. Robinson must sell to make an annual income of at least $8,000 = x

then total commission on x policies = 183x

Total income using x policies = 4800+183x

Since she wants to make an annual income of at least $8,000. so we can write inequality as:

$4800+183x>8000$

Hence required inequality is $4800+183x>8000$ .
