Answer:

The discriminant of the quadratic equation is -7.

Step-by-step explanation:

We are given the following quadratic equation in the question:

x^2+x+2 = 0

Comparing to general quadratic equation:

ax^2+bx+c = 0\\a = 1\\b = 1\\c = 2

We have to find the discriminant of the quadratic equation.

Formula:

d = b^2-4ac

Putting values, we get,

d = (1)^2 - 4(1)(2) = 1 - 8 = -7

Thus, the discriminant of the quadratic equation is -7.

x is the independent variable.

y is the dependent variable.

-3 is the rate of change (slope).

-7 is the initial value.

Step-by-step explanation:

The form of the linear relation is y = m x + b, where

  • m is the rate of change (slope)
  • b is the initial value(value of y at x = 0)
  • x is the independent variable
  • y is the dependent variable

∵ The equation of the line is y = -3 x - 7

- Compare it with the form above

∴ m = -3

∵ m is the rate of change

∴ The rate of change is -3

∴ b = -7

∵ b is the initial value

∴ The initial value is -7

∵ y depends on x

∴ x is the independent variable

∴ y is the dependent variable

x is the independent variable.

y is the dependent variable.

-3 is the rate of change (slope)

-7 is the initial value.

Answer:

Y1 is parallel to Y2 and L1 to L2.

Step-by-step explanation:

A line is 180°. To find the degree the angles I subtracted 117 and 63 by 180 to find thair respective angles. (Also 117+63 equil 180) meaning that the Y's and L's are parallel to each other.
