Answer:
The solution of the system of equation in coordinate form is (2, 0)
Step-by-step explanation:
The given equation are;
2·x - y = 4....................(1)
5·x + 2·y = 10..............(2)
Multiplying equation (1) by 2 and subtract it from equation (2) gives;
5·x + 2·y - 2 × (2·x - y) = 10 - 2×4
5·x - 4·x + 2·y - 2·y = 2
x = 2
From equation (1), we have 2·x - y = 4, when x = 2, we get;
2×2 - y = 4
y = 2×2 -4 = 0
y = 0
Therefore;
The solution of the system of equation in coordinate form is (2, 0).
The value of car after 12 years is $ 2982.92
<em><u>Solution:</u></em>
Given that,
A new car is purchased for 17000 dollars
The value of the car depreciates at 13.5% per year
<em><u>To find: Value of car after 12 years</u></em>
<em><u>The decreasing function is given as:</u></em>
Where,
y is the future value
a is the initial value
r is the decreasing rate in decimal
t is the number of years
From given,
<em><u>Substituting the values we get,</u></em>
Thus value of car after 12 years is $ 2982.92
Answer:
When a=-2, and b=5, a+b = -2+5, which is equal to 3.
Let me know if this helps!
Y-2x=8. i just finished learning this lesson and i’m almost sure this is correct. please let me know if proven otherwise!
