Answer:

See below

Step-by-step explanation:

1. (refresh if you cant see it)

F = \frac{9}{5}C+32\\\text{Bring variable C to left side}\\-\frac{9}{5}C=-F+32\\\text{Multiply by -1}\\\frac{9}{5}C=F-32\\\text{Multiply the equation by 5/9 to get C by itself}\\C = \frac{5}{9}(F-32)

2.

2(x + 3) = 20

Distribute.

2x + 6 = 20 \neq 2x + 3 = 20

Your answer is false.

3.

x \geq -2 because even though it includes the expression "x>5", those values are also above -2, including 5.

What does the line 5x + 4y = -6 look like
RoseWind [281]

Answer:

See attached photo for graph

Step-by-step explanation:

Solve the equation for y...  (that means get y by itself)

4y = -5x - 6         (subtract 5x from both sides)

y = -(5/4)x - 6/4  (divide both sides by 4)

y = -(5/4)x - 3/2      (simplify)

Now you can graph using slope-intercept method.   The y-intercept is -3/2, and the slope is -5/4

A woman wishes to rent a house within 9 miles of her work. If she lives x miles from her work, her transportation cost will be c
I am Lyosha [343]

Answer:

the woman has to live 1 mile from work to minimize the expenses

Step-by-step explanation:

Given the data in the question;

the distance within 9 miles ⇒ 0 < x > 9

Total costs Q = cx + 4c/( x + 1)

costs should be minimum  ⇒ dQ/dx = 0

⇒ d/dx [ cx + 4c/( x + 1) ] = 0

⇒ ( x + 1)² = 4

take square root of both side

√[ ( x + 1)² ] = √4

x + 1 = 2

x = 2 - 1

x = 1

Therefore, the woman has to live 1 mile from work to minimize the expenses

a company borrowed 25,000 and was charges 3.5% and was charged 2,625 in interet...how long was it before the company repaid the
Sladkaya [172]
We'll have to assume that interest is charged annually.

interest = i = p*r*t, where p is the initial amount ($25000), r is the annual interest rate as a decimal fraction, and t is the length of time, in years.

Then  $2625 = $25000*0.035*t.  Solve for t:

$2625
------------ = 0.035t   =  0.105.  Dividing both sides by 0.035, we get
$25000

t = 3 years (answer)
