What are the x and y-intercepts and the vertex of x^2+2x-80? Sketch the graph and write the equation in graphing form.

Answers

Answer 1
X^2 + 2x - 80
So if we factorise
(X+10)(x-8)
So x intercepts are (-10, 8)
The y intercept and vertex is -80

Write the expression as a single logarithm.

log₄ 2x - log₄ 6y

Answers

Answer:

[tex]log_{4}(\frac{2x}{6y})[/tex]

Step-by-step explanation:

According to the Quotient Rule (Logarithmic Property):

[tex]log_{a}x - log_{a}y = log_{a}(\frac{x}{y})[/tex]

Therefore, you could combine the logarithmic expressions as:

[tex]log_{4}2x - log_{4}6y = log_{4}(\frac{2x}{6y})[/tex]

Optional:

If ever you're required to simplify it further, [tex]log_{4}(\frac{2x}{6y})[/tex] will be:

[tex]log_{4}(\frac{2x}{6y}) = log_{4}(\frac{x}{3y})[/tex]

Answer:

Rational

Step-by-step explanation:

Rational numbers include fractions and decimals that end or have a pattern. Irrational numbers, however, do not end and have an arbitrary pattern. -0.25 is rational because it is a terminating decimal which means it ends.

Examples of irrational numbers include:
