Answer:

Devon

Step-by-step explanation:

lets use t=1 to compare

1. -5(12t+9)

if t = 1, -5(12+9) = -5(21) = negative number

2. 2(-6t-8)

if t = 1, 2(-6-8) = 2(-14) = negative number

3. -6(-2t+18)

if t = 1, -6(-2+18) = -6(16) = negative number

4. (-4(-3t-2)

if t = 1, -4(-3-2) = -4(-5) = 20 positive number

At a large nursery, a border for a rectangular garden is being built. Designers want the border’s length to be 5 feet greater th
Salsk061 [2.6K]

Let

x--------> the border’s length

y--------> the border’s width

P--------> perimeter of the border


we know that

x=5+y------> equation 1

P=2*[x+y]-----> P=2x+2y

P <=180 ft

(2x+2y) <= 180-------> equation 2


substitute the equation 1 in equation 2

2*[5+y]+2y <= 180

10+2y+2y <= 180

4y <= 180-10

4y <=170

y <=42.5 ft

so

the maximum value of the width is 42.5 ft

for y=42.5 ft

x=42.5+5------> x=47.5 ft


the answer is

the width of the border is less than or equal to 42.5 ft

If c(x)=5/x-2 and d(x)=x+3, what is the domain of (cd)(x)?
pickupchik [31]

Answer:

The domain is all Real x except x = 2 .

Step-by-step explanation:

(cd)(x) = ( 5 / x-2) * x+3

=  5(x+3)/(x-2)

The domain is all Real x except x = 2 .

(because when x = 2 (cd)(x) is undefined).
