P varies inversely with x. If P = 7 when x = 8, find the value of P when x = 7.

inna [77]

Answer:

P = 8

Step-by-step explanation:

Given that P varies inversely with x then the equation relating them is

P = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition P = 7 when x = 8 , then

7 = $\frac{k}{8}$ ( multiply both sides by 8 )

56 = k

P = $\frac{56}{x}$ ← equation of variation

When x = 7 , then

P = $\frac{56}{7}$ = 8

Solve for x: 3x − 2 > 5x + 10. (5 points)<br> 1) x > 6<br><br> 2) x −6

san4es73 [151]

Answer:

$x$

Step-by-step explanation:

$3x-2>5x+10$

Add 2 to both sides

$3x-2+2>5x+10+2$

Simplify

$3x>5x+12$

Subtract $5x$ from both sides

$3x-5x>5x+12-5x$

Simplify

$-2x>12$

Multiply both sides by $-1$ (reverse the inequality)

$(-2x)(-1)$

Simplify

$2x$

Divide both sides by $2$

$\frac{2x}{2}$

Divide the numbers: $\frac{2}{2} =1$

$=x$

Divide the numbers: $\frac{-12}{2}$

Apply fraction rule: $\frac{-a}{b} =-\frac{a}{b}$

$=\frac{12}{2}$

Divide the numbers: $\frac{12}{2} =6$

$=-6$

$x$
