Step-by-step explanation:
Compare the given equation ...
y = (5/9)x
to the equation for proportionality ...
y = rx
where r is the constant of proportionality.
Matching the two patterns, you should be able to see that r = 5/9.
The constant of proportionality is 5/9.

You borrow $1400 from a friend and promise to pay back
$2000 in two years. What simple interest rate, to the nearest
tenth of a percent, will you pay?
Answer:
21.4%
Step-by-step explanation:
You would pay back a 21.4%
The simple interest rate on the loan of $1400 is approximately 21.4% per year.
What is the simple interest rate of the loan?The simple interest can be expressed as:
A = P( 1 + rt )
Where A is accrued amount, P is the principal, r is the interest rate and t is time.
Given the parameter:
Principal P = $1400
Accrued amount A = $2000
Time t = 2 years
Interest rate r =?
Plug these values into the above formula and solve for the interest rate.
A = P( 1 + rt )
[tex]r = \frac{1}{t} * ( \frac{A}{P} - 1 ) \\\\r = \frac{1}{2} * ( \frac{2000}{1400} - 1 ) \\\\r = \frac{1}{2} * ( \frac{2000}{1400} - 1 ) \\\\r = 0.21428[/tex]
Convert r decimal to R a percentage
R = 0.214 × 100
R = 21.4% per year
Therefore, the rate is approximately 21.4% per year.

Solve for x 5x+10=7x+18
Answer:
I think it is x=-4
Step-by-step explanation:
Step 1: Subtract 7x from both sides.
5x+10−7x=7x+18−7x
−2x+10=18
Step 2: Subtract 10 from both sides.
−2x+10−10=18−10
−2x=8
Step 3: Divide both sides by -2.

The function f is defined by f(x) = - |x|, The expression for g (x) will be g (x) = - |x|+3.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that the function is,

Geometric transformation is the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
It is obtained from the graph that the point for the function g (x) is translated by the 3 units right.
Thus, the function f is defined by f(x) = - |x|, The expression for g (x) will be g (x) = - |x|+3.

Answer:
x = 30 over 11
Step-by-step explanation:
6(9x-5)-4(3+2x)-3(8x-20) = 24
54x-30-12-8x-24x+6 = 24
22x = 24+36
22x = 60
then divide both sides by 22
x = 30 over 11

Hey there!
Remember, equivalent means equal.
So we need to find some fractions that are equal to 4/7 and 3/5.
We can easily do that.
First, let's take 4/7.
Let's multiply the top & bottom by 2:
8/14
4/7 and 8/14 are equivalent.
Let's multiply the top & bottom by 2:
16/28
We can keep multiplying...
Also, there's no reason why we cannot multiply by 3, 4, 5, 6, 7, 8...
In other words, there are infinitely many fractions equivalent to 4/7.
Same with 3/5:
6/10, 12/20...
Hope everything is clear.
Let me know if you have any questions; if so, please ask.

9. Every school day, Lucas bikes to school, 12 miles away at 8 miles per hour. Today, Lucas was thinking about planning his sister’s party in the evening, and, distracted, travelled the first four mile at only 6 miles per hour. At what speed must he travel the last eight miles to reach school in time?
Answer:
Step-by-step explanation:
The question may be answered easily by first determining how far we would ride the bike in 1 hour. Riding the bike 12 mph (miles per hour) for one hour, we would ride the bike 12 miles.
Since 20 minutes is 1/3 of a hour, divide 12 by 3 to find out how far the biker traveled in 1/3 of the time:4 miles. that is the answer and the steps!!

A guest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent. This can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days. How many phone calls should she expect after a week?
Answer:
17
Step-by-step explanation:
After a week he can expect 17 calls.
Given that,
A guest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent.
This can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days.
How many phone calls should she expect after a week is to be determined.
The function which is in format f(x) =aˣ where a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
Here,
in 1 week = 7 Days
Now,
D = x
y = 30(0.92)ˣ
now put x = 7
y = 30(0.92)⁷
y = 30 * 0.55
y ≈ 17
Thus, After a week he can expect 17 calls.

The table represents a linear function. A two column table with six rows. The first row, x, has the entries negative 4, negative 2, negative 1, 1, 2. The second column, y, has the entries, negative 2, negative 10, negative 14, negative 22, negative 26. What is the slope of the function? –8 –4 2 5 Mark this and return
The slope of a line indicates how steep it is calculated mathematically as "rise overrun". It calculates the rate where the variable y changes when the relevant variable changes, and the further calculation can be defined as follows:
Given Points:
[tex](-4,-2) , (-2,-10)[/tex]
To find:
slope (m)=?
Solution:
[tex](-4,-2),(-2,-10)\\x_{1} =-4\\y_{1} =-2\\x_{2}= -2\\y_{2}=-10\\[/tex]
Using formula:
[tex]slope(m)=\frac{y_{2-} y_{1} }{x_{2-} x_{1} } \\=\frac{-10-(-2)}{-2-(-4)} \\\\=\frac{-10+2}{-2+4}\\=\frac{-8}{2} \\=-4[/tex]
Therefore, the slope is "- 4".
