Kaya's family spends $105 to rent a boat for 7
days. The total cost, c, of the boat rental is
proportional to the number of days, d, the
family rents the boat.

A. How much does it cost, in dollars, to
rent the boat for 3 days? SHOW
WORK!
B. Create an equation using "c" and "d" to
represent the proportional relationship
Answer:
A: $45 for 3 days
B: c=d(15)
Step-by-step explanation:
A: If 105 is the cost for 7 days and we want to find the cost for only 3 we have to find the cost for one day to start with so, 105 divided by 7 which is $15 so its 15 dollars a day then you multiply 15 by the number of days we want (3) and you get $45.
c) Which of these numbers is a square number?

what is the slope of the line graphed below? (3,3) (0,-6)
Answer:
Where is the line
Step-by-step explanation:
Answer:
The slope of the lines is 3.
Step-by-step explanation:
Since I can't actually graph it, we can make a table
x y
3 3
0 -6
From 3 to -6, you subtract 9 (for the y section)
From 3 to 0, you subtract 3 (for the x section)
Now all you need to do is divide y by x
y/x = -9/-3 = 3
It's a positive 3, because two negatives times each other will always result in a positive.
Slope = 3

Step-by-step explanation:
The equivalent of the expression, 2 x 2 x 2 x 2 x 2 x 2 is 2⁶.
How to find an equivalent expression?An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.
An equivalent expression is an expression that has the same value or worth as another expression, but does not look the same.
Therefore, let's simplify the expression to find its equivalent as follows:
2 x 2 x 2 x 2 x 2 x 2 = 2⁶

Answer: Lower-right corner [tex]3^7 \times \frac{1}{3^4}[/tex]
Explanation:
We use the rule that
[tex]a^{-b} = \frac{1}{a^b}[/tex]
The negative exponent tells us to apply the reciprocal if we want the exponent to be positive.
In this case, a = 3 and b = 4
So,
[tex]a^{-b} = \frac{1}{a^b}\\\\3^{-4} = \frac{1}{3^4}[/tex]
which is why overall,
[tex]3^7\times 3^{-4} = 3^7 \times \frac{1}{3^4}[/tex]

Using the graph above identify the constant of proportionality between the number of shirts and how much they cost? Hint: simplify your answer
A. K=80
B. K=20
C. K=10
D. k=8
Answer:
We conclude that the constant of proportionality between the number of shirts and how much they cost is:
k = 8
Hence, option 'D' is correct.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get
y ∝ x
y = kx
k = y/x
where k is called the constant of proportionality
Given the points
(10, 80)(20, 160)(50, 400)For (10, 80)
substituting y = 80 and x = 10 in the equation
k = y/x
k = 80/10 = 8
For (20, 160)
k = y/x
k = 160/20 = 8
For (50, 400)
k = y/x
k = 400/50 = 8
It is clear that the value of k is the same for all the points.
Thus, the value of k = 8
Therefore, we conclude that the constant of proportionality between the number of shirts and how much they cost is:
k = 8
Hence, option 'D' is correct.
(-s - 5) + (-2s + 2)
Answer:
-3s - 3
Step-by-step explanation:
Using PEMDAS you first want to get rid of the parenthesis, but in this case you don't have to change signs or anything because you're simply adding what's in the second parenthesis. From that you want to simplify by combining like terms.
= -s - 5 - 2s + 2
= -3s -3

[tex]step - 2 : \\ rewrite[/tex]
[tex]\frac{x}{3} + 1= - 8[/tex]
[tex]step - 3 : \\ subtract \: 1 \: from \: both \: sides[/tex]
[tex] \frac{x}{3} + 1 - 1 = - 8 - 1[/tex]
[tex] \frac{x}{3} = - 9[/tex]
