!!!!!!!!!!!!!!!!!!!!!!!!
A car manufacturer is reducing the number of incidents with the transmission by issuing a voluntary recall. During week 3 of the recall, the manufacturer fixed 391 cars. In week 13, the manufacturer fixed 361 cars. Assume that the reduction in the number of cars each week is linear. Write an equation in function form to show the number of cars seen each week by the mechanic. f(x) = 3x + 400 f(x) = 3x + 391 f(x) = −3x + 391 f(x) = −3x + 400

Answer:

f(x)= -3x + 400

Step-by-step explanation:

\frac{x-x_{1} }{x_{2}-x_{1}  } = \frac{y-y_{1} }{y_{2}-y_{1}  }

\frac{x-3}{13-3} =\frac{y-391}{361-391}

-3 ( x-3 ) = (y - 391 )

-3x + 400

Select the two values of x that are roots of this equation.<br>x + 2x - 6 = 0​
VLD [36.1K]

For this case we must solve the following quadratic equation:

x ^ 2 + 2x-6 = 0

Where:

a = 1\\b = 2\\c = -6

The solution is given by:

x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}

Substituting:

x = \frac {-2 \pm \sqrt {2 ^ 2-4 (1) (- 6)}} {2 (1)}\\x = \frac {-2 \pm \sqrt {4 + 24}} {2}\\x = \frac {-2 \pm \sqrt {28}} {2}\\x = \frac {-2 \pm \sqrt {2 ^ 2 * 7}} {2}\\x = \frac {-2 \pm2 \sqrt {7}} {2}\\x = -1 \pm \sqrt {7}

Thus, we have two roots:

x_ {1} = - 1+ \sqrt {7}\\x_ {2} = - 1- \sqrt {7}

ANswer:

x_ {1} = - 1+ \sqrt {7}\\x_ {2} = - 1- \sqrt {7}

Solve the following exponential function 4^3x = 4^2
Alekssandra [29.7K]

For this case we must solve the following equation:

4^{3x} = 4 ^ 2

By definition, for the bases to be equal then the exponents must also be the same. Thus, we have to:

3x = 2

Dividing by 3 to both sides of the equation we have:

x = \frac {2} {3}

Answer:

x = \frac {2} {3}
