2y = x + 3 5y = x - 7 What is the solution set of the given system?
prohojiy [21]
<span>2y = x + 3 then x = 2y - 3
5y = x - 7 then x = 5y + 7

so 
</span>2y - 3 = 5y + 7
2y - 5y = 7 + 3
-3y = 10
y = -10/3
y = -3 1/3

<span>2y = x + 3
</span>2 (-10/3) = x + 3
-20/3 - 3 =x
-29/3 = x
-9 2/3 =x
or
x = -9 2/3

solutions: x = -9 2/3 and y = -3 1/3

n200080 [17]

The value of a car after 10 years be $20898.27 if the car rental company assumes each car in their fleet depreciates by 6% per year option (a) $20898.27 is correct.

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent \rm y = a^x

where a is a constant and a>1

We can solve this problem by exponential function:

The word  depreciate means the price is decreasing.

We can find the value be when the car is 10 years old:

p = 38800(1 - 0.06)¹⁰

p = 38800(0.94)¹⁰

p = 20898.266 ≈ $20898.27

Thus, the value of a car after 10 years be $20898.27 if the car rental company assumes each car in their fleet depreciates by 6% per year option (a) $20898.27 is correct.

a set of data has the following linear regression equation y = 1+3x what does the equation predict for a value of x=14?
trasher [3.6K]
In this problem, you are simply going to input 14 for x in your equation.

y = 3x + 1
y = 3(14) + 1
y = 42+1
y = 43
This means, when x=14, y=43

Hope this helps!
