The equation
$y = - 3 {x}^{2} - 29x + 30$
is quadratic, since the highest power of x is x^2. The quadratic term is -3x^2, the linear term is -29x, and the constant is 30.

Solve the system of equations by graphing. x+y=-9 4x+y=-19

shutvik [7]

For this case we have the following system of equations:

$x + y = -9\\4x + y = -19$

We multiply the first equation by -4:

$-4x-4y = 36$

We have the following equivalent system of equations:

$-4x-4y = 36\\4x + y = -19$

We add the equations:

$-4x + 4x-4y + y = 36-19\\-3y = 17\\y = - \frac {17} {3}$

We find the value of the variable "x":

$x = -9-yx = -9 - (- \frac {17} {3})\\x = -9 + \frac {17} {3}\\x = \frac {-27 + 17} {3}\\x = - \frac {10} {3}$

Thus, the solution of the system is:

$(x, y): (- \frac {10} {3}, - \frac {17} {3})$

2.0Plss solve for x...........................

Paul [167]

Answer:

x = - 7

Step-by-step explanation:

( x + 139 ) and 132 are vertically opposite angles.

Vertically opposite angles are equal,

x + 139 = 132

x = 132 - 139

x = - 7

Answer: 0.4

Step-by-step explanation:

Given: Cumulative exponential distribution:

$P(x$

As per given,

$P(x$

$P(0.5 < X < 3) \\\\=P(X$
