What is the approximate solution of this system of equations? y = x^2 + 3x + 3; y = x^2 + x + 2

1 answer:

6 0

X^2 + 3x + 3 = x^2 + x + 2
2x = -1
x = -1/2

y = (-1/2)^2 + (-1/2) + 2
y = 1/4 - 2/4 + 8/4
y = 7/4

answer
solution of this system (-1/2 , 7/4)

A clothing business finds there is a linear relationship between the number of shirts, Q ,it can sell and the price, P , it can

Vlad [161]

Answer:

P = -0.004Q + 149

Step-by-step explanation:

The general form of the linear equation is:

$P=aQ+b$

The slope of the equation (a) can be found by using the two given points (4,000; $133) and (27,000; $41)

$a = \frac{\$41-\$133}{27,000-4,000}\\a=-0.004$

Applying the point (4,000; $133) to the equation below yields in the linear equation for Price as a function of the number of shirts:

$P-P_0=a(Q-Q_0)\\P-133=-0.004(Q-4,000)\\P = -0.004Q+149$

The linear equation is:

P = -0.004Q + 149
