• _Value of the Discriminant:
• Number of Solutions:
• Number of x-intercepts:
• Type of Solutions:

Answers

Answer 1

Answer:

Step-by-step explanation:

value of discriminant:

[tex]5^{2} - 4 (2)(-4)\\=25+32\\=57\\[/tex]

As the value of discriminant is larger than zero, so there are 2 distinct solutions.

2 solutions also mean there are 2 x-intercepts.

∠e and ∠i; ∠f and ∠h
∠e and ∠g; ∠f and ∠h
∠e and ∠i; ∠f and ∠g

Answers

Answer:

im pretty sure the answer is ∠e and ∠i; ∠f and ∠g

but if not im so sorry :(

Answer:

The third answer

Step-by-step explanation:

Each angle on both triangles has a set of lines, either one, two, or three. These lines are used to show congruency over a number of lines or angles. So one angle will correlate with whatever other angles have that same number of lines. For example, e and g both have two lines, this means they are corresponding and congruent.

m/n(x), x≠

Answers

When we evaluate the quotient functions, (mn)(x) for x = -3

(mn)(-3) = 9 and (m/n) (x), x ≠ 0

How did we evaluate the quotient function?

To evaluate the quotient function (mn)(x) for x = -3, we  substituting x = -3 into the function mn(x).

This gives us (mn)(-3) = m(-3) × n(-3) = (-3)² × (-3) = 9.

We then need to evaluate (m/n)(x), x ≠ 0.

This is done by dividing the function m(x) by the function n(x). This gives us (m/n)(x) = m(x) / n(x) = x^2 / x = x. However, this expression is undefined when x = 0, because division by zero is undefine

3x + 5 = 6x – 13
please please help!

Answers

Answer:

Simplifying

3x + -5 = 6x + -13

Reorder the terms:

-5 + 3x = 6x + -13

Reorder the terms:

-5 + 3x = -13 + 6x

Solving

-5 + 3x = -13 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

-5 + 3x + -6x = -13 + 6x + -6x

Combine like terms: 3x + -6x = -3x

-5 + -3x = -13 + 6x + -6x

Combine like terms: 6x + -6x = 0

-5 + -3x = -13 + 0

-5 + -3x = -13

Add '5' to each side of the equation.

-5 + 5 + -3x = -13 + 5

Combine like terms: -5 + 5 = 0

0 + -3x = -13 + 5

-3x = -13 + 5

Combine like terms: -13 + 5 = -8

-3x = -8

Divide each side by '-3'.
