Anna and Hannah have \$80$80dollar sign, 80 each. Their friend offered to invest their money, promising to return a sum rrr times as great as what they invested. Anna was suspicious, so she invested \$20$20dollar sign, 20 only, but Hannah invested her entire \$80$80dollar sign, 80. Fortunately, the friend did indeed return a sum rrr times as great to each.

They decided to make another investment. This time, Hannah invested all of the money returned to her, and Anna invested the money returned to her and the remaining \$60$60dollar sign, 60. Again, they got a sum rrr times as great as what they invested. In the end, Hannah had twice the amount Anna had.

Write an equation in terms of rrr that models the situation.

John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. The pizza cost $12.50. They spend a total of $16.85. Write an equation to represent the problem. Find the cost of one large drink.

### Answers

**Answer:**

Hm, okay.

**Step-by-step explanation:**

So, if the pizza cost $12.50, and the total money spent is $16.85, we must first subtract our money spent on pizza from the total amount spent.

$16.85 - $12.50 = $4.35

So, that means that John and his two friends spent $4.35 on 3 large drinks. But how do we figure out how much each individual drink cost?

We divide $4.35 by 3.

$4.35 / 3 = $1.45.

So, the amount of money spent on one large drink was $1.45.

Stefan said that the y-intercept for the graph of the function f(x)=3log(x−7)+1 is 1. He also said that as x approaches positive infinity, the graph of f(x) approaches positive infinity. Describe which of Stefan's statements, if any, are incorrect, and, if so, correct the statements.

### Answers

**Answer:**

see below

**Step-by-step explanation:**

f(x)=3log(x−7)+1

There is no y intercept

log (x) does not intercept the y axis. This shifts the function 7 units to the right so the graph will not intercept the y axis

**Answers:**

**His first statement is incorrect**

**His second statement is correct.**

======================================

Explanation:

The first statement is incorrect because plugging x = 0 into f(x) leads to

f(x) = 3*log(x-7)+1

f(0) = 3*log(0-7)+1

f(0) = 3*log(-7)+1

We stop here because we cannot take the log of a negative number (unless you want a complex number but that's for another time). This means that x = 0 is not in the domain. The domain is x > 7 to ensure that x-7 > 0. That way we avoid taking the log of a negative number, and taking the log of zero as well.

The vertical asymptote is at x = 7 and the log curve is entirely to the right of it, so there's no way it's reaching the y axis.

Simply put: there is no y intercept for this function.

---------------------

The second statement is correct.

The function y = log(x) has y go off to infinity when x does.

The same applies to y = 3log(x) and y = 3log(x-7) and y = 3log(x-7)+1

We can say it "rises to the right" as another way of describing part of the end behavior.

c.the slope is 1/3 and the y intercept is -2/5

d.the slope is 2/5 and the y intercept is -1/3

### Answers

**Answer: a. the slope is -2/5 and the y-intercept is -1/3**

**Step-by-step explanation:**

**Find the slope by finding the difference in x-values divided by the difference in y-values**

**(1/4 ,-13/30) and (-3/4, -1/30) are useful values**

** -13/30 --1/30 = -12/30 = -2/5 is the rise **

**-1/4 - -3/4 = 1 is the run **(-2/5)/1 Division by 1 leaves the original numerator)

**the slope is -2/5**

To find the y intrcept, substitute the y and x values from any given coordinate into the slope intercept form and solve for b

y= mx + b

-3/5 = (-2/5)(2/3) + b

-9/15 + 4/15 = b

-5/15 = b

**-1/3 = b This is the y-intercept**

Gerald is going mini golfing at Golf-O-Rama with his family. For his family of 5 to play it costs $34. They were charged for three student tickets and two adult tickets. If a student ticket costs 3/4 as much as an adult ticket costs, how much does one student ticket cost?

### Answers

Answer:

The cost of one student ticket = $6

Step-by-step explanation:

They were charged for three student tickets and two adult tickets.

Let the cost of one student ticket = a

Let the cost of one Adult ticket = b

If a student ticket costs 3/4 as much as an adult ticket costs

a = 3/4(b)

= 3b/4

For his family of 5 to play it costs $34.

Hence:

3a + 2b = $34

a = 3b/4

3(3b/4) + 2b= 34

9b/4+ 2b = 34

9b + 8b / 4 = 34

17b/4 = 34

17b = 34 × 4

b = 136/17

b = $8

The cost of one Adult ticket = $8

Note that:

a = 3b/4

a = 3(8)/4

a = 24/4

a = $6

Therefore, the cost of one student ticket = $6
