Answer:

x = 57

Step-by-step explanation:

Where parallel lines are crossed by a transversal, all obtuse angles are congruent and supplementary to all acute angles, which are also congruent.

x = 180 -123

x = 57

HELP!!!!!!!

Answer:

Option A, Left by 4 units

Step-by-step explanation:

Step 1: Convert g(x) to a function square

We currently have g(x) in this order: $ax^2 + bx + c$

However, we want g(x) to be in this order: $(ax + c)^{2}$

The first thing we have to do is to factor it out:

$g(x)=x^{2}+8x+16$

$g(x) = (x + 4)(x + 4)$

$g(x) = (x+4)^{2}$

Step 2: Now we can see which way we need to move it

The original form is: $f(x) = (ax - b)^{2}$

Since the - has changed to a +, that means that we moved -4 spaces down the x-axis. This means that we move left by 4 units.

Answer: Option A, Left by 4 units

What is the absolute value of -4-√2i

rodikova [14]

For x +iy absolute value = √(x² + y²)

Absolute value of -4-√2i = -4-i√2, comparing x = -4, y= -√2

Absolute value = √( (-4)² + (-√2)²),

(-4)² = (-4)*(-4) = 16, (-√2)² = -√2 * -√2 = 2

= √( (-4)² + (-√2)²)

= √(16 + 4) = √20

√20 = √(4*5) = √4 * √5 = 2√5

Absolute value = 2√5
