Answer: Hence, our required model will be

Explanation:
Since we have given that
Luana bought a new phone and
For 3 months, the amount she paid = $175
For 6 months, the amount she paid = $295
Now, we have to model an equation ,
Here, let cost be 'C' and
Let number of months be 'm'.
So, we will use the "equation of line" i.e. for two point slope form :
Here y represented by 'C' and x represented by 'm'
So,

Hence, our required model will be

(x+4)

Answer:
x = -2, y = -4, or (-2, -4).
Step-by-step explanation:
5x + y = -14
5x - 3y = 2
If we look at the first equation, we can see that y can be easily isolated.
5x + y = -14
Subtract 5x from both sides.
y = -5x - 14
Now we have a variable that we can plug into the second equation.
5x - 3y = 2
5x - 3(-5x - 14) = 2
Distribute the -3 across each term in the parentheses.
5x + 15x + 42 = 2
Combine like terms.
20x + 42 = 2
Subtract 42 from both sides.
20x = -40
Divide both sides by 20 to isolate x.
x = -2
Plug in x = -2 back into one of the equations to find y.
y = -5x - 14
y = -5(-2) - 14
Multiply.
y = 10 - 14
Subtract.
y = -4
Our solution is x = -2, y = -4, or (-2, -4).
Check your answer by plugging both values into one of the equations.
5x - 3y = 2
5(-2) - 3(-4) = 2
-10 + 12 = 2
2 = 2
Your answer is correct.

Set it up as a ratio:
mans shadow over mans height (4/6 ) equals flag pole shadow over flag pole height (15/x)
set them to equal each other:
4/6 = 15/x
cross multiply: 4*x =4x, 15*6 = 90
so you have 4x = 90
now divide both sides by 5 to solve for x, which is the height of the flag pole:
x = 90 / 4 = 22.5 feet tall
Hello,
There are 24 hours in a day. If 25% of your day is spent at school, then you spent (24)(0.25) = 6 hours at school.
If 8% of your day is spent eating, then you spent (24)(0.08) = 1.92 hours eating.
Together, this is 6 + 1.92 = 7.92 hours ≈ 7.9 hours spent at school and eating in one day.
Hope this helps!
