I believe the correct answer would be perfect negative association. It is describe as perfect since the points reflects an almost linear graph or relation. It is  negative since as Y increases, the value of X decreases or vice versa. Hope this answers the question.

Aleonysh [2.5K]

Let

x-------> Leila 's profit

y------> Jo's profit

we know that

\frac{x}{y} =\frac{3}{4} ----------> equation 1

For y=\$60

<u>Find the value of x</u>

Substitute the value of y in the equation 1

\frac{x}{60} =\frac{3}{4}

x=60*\frac{3}{4}

x=\$45

therefore

<u>the answer is</u>

Leila make \$45 in profit

A restaurant earns $10 for each hour worked up to 40 hours each week and 15 for each additional hour worked over 40 hours. If x
makvit [3.9K]

Answer:

f(x) =  15x - 200

Step-by-step explanation:

Given

Earnings = \$10 per hour for 40 hours, weekly

Additional\ Hour = \$15 per hour over 40 hours, weekly

Required

Determine f(x)

From the question, we have that

x represents hours worked

Earnings in 40 hours is: 40 * 10 = $400

Hours over 40 will be: x - 40

So, earnings during this time will be: (x - 40) * 15

Total earnings is:

f(x) = 400 + (x - 40) * 15

f(x) = 400 + 15x - 600

f(x) =  15x - 600 + 400

f(x) =  15x - 200

Write the explicit equation for the sequence 5,8,11,14
mamaluj [8]
Consecutive terms differ by 3, so

a_n=a_{n-1}+3=a_{n-2}+2\times3=a_{n-3}+3\times3=\cdots=a_1+(n-1)\times3

Since the first term is a_1=5, the formula for the sequence is

a_n=5+3(n-1)=3n+2
