Answer:

The are congruent.
They are non-adjacent.

Step-by-step explanation:

Where a transversal crosses parallel lines, the angles outside the parallel lines are called exterior angles. When they are on opposite sides of the transversal, they are alternate exterior angles.

Alternate exterior angles are congruent.

The share a side (the transversal, but not a vertex. So they are non-adjacent.

_____

Additional comment

In this geometry, corresponding angles are congruent. Of course, vertical angles are always congruent. Each alternate exterior angle is a vertical angle with one that is corresponding to the other alternate exterior angle.

Write a linear function f with the values f(0)=-1 and f(2)=-5

Darya [45]

Answer:

f(x) = - 2x - 1

Step-by-step explanation:

Let the linear function f(x) is given by f(x) = ax + b where a and b are unknown constants.

Given that f(0) = -1 and f(2) = -5

Hence, a(0) + b = - 1, ⇒ b = - 1

Again from the condition given

a(2) + b = -5, ⇒ 2a - 1 = - 5, ⇒ 2a = - 4, ⇒ a = - 2.

Therefore, the linear function is f(x) = - 2x - 1 (Answer)

True or false (picture provided)

Kitty [74]

Answer:

True

Step-by-step explanation:

we know that

A non-negative number is a real number greater than or equal to zero

In this problem

we have

$x\geq 0$

The solution of the inequality is all real numbers greater than or equal to zero [0,∞)

Therefore

$x\geq 0$ express a non-negative number in symbols

Show that the equation x cubed + 8x = 30 has a solution between x = 2.2 and x =2.3 ?

tatuchka [14]

$x^3+8x=30\\
x^3+8x-30=0\\\\
2.2^3+8\cdot2.2-30=10.648+17.6-30=-1.752\\
2.3^3+8\cdot2.3-30=12.167+18.4-30=0.567
$

For $x=2.2$ the value of $x^3+8x-30$ is negative, and for $x=2.3$ the value is positive which means between $x=2.2$ and $x=2.3$ there is an x for which the value of $x^3+8x-30$ is equal to 0 and therefore there is a solution.
