Algebraic expression for 15x + 8

1 answer:

5 0

Yes, this is an algebraic expression, and is the simplest possible. Cannot be simplified further, and cannot be factored.

If we know the value of x, we can evaluate it to a number, otherwise, it stays as it is.

Or, perhaps the question is not complete.

What is the domain of the function f(x) =x+1/ X^2-6x+8?

SpyIntel [72]

Answer:

The domain of the function is all real values of x, except $x = 4$ and $x = 2$

Step-by-step explanation:

We are given the following function:

$f(x) = \frac{x+1}{x^2-6x+8}$

It's a fraction, so the domain is all the real values except those in which the denominator is 0.

Denominator:

Quadratic equation with $a = 1, b = -6, c = 8$

Using bhaskara, the denominator is 0 for these following values of x:

$\Delta = (-6)^2 - 4(1)(8) = 36-32 = 4$

$x_{1} = \frac{-(-6) + \sqrt{4}}{2} = 4$

$x_{2} = \frac{-(-6) - \sqrt{4}}{2} = 2$

The domain of the function is all real values of x, except $x = 4$ and $x = 2$

The equation of the line of best fit of a scatter plot is y = –7x – 2. What is the the y-intercept? (4 points)

slava [35]

-2

I just took this class for Algebra 1... it would be -2

y=mx+b

this is the equation you will use for these problems. the "b" in the equation represents the y intercept. In this specific problem -2 is the y intercept

Brodrick correctly represents a composite number as the product of a pair of prime factors. Which equation could show Brodricks

olchik [2.2K]

Answer:

G-7×17=119

Step-by-step explanation:

A prime number is a number which has only two factors, 1 and itself.

A composite number on the other hand is any number that has more than two factors.

In the options

In F-5×15=75, 15 can still be decomposed into 5X3

In H-9×19=171, 9 can still be decomposed into 3X3

In J-11×21=231, 21 can still be written as 7X3.

So option G is the only equation which could show Brodricks work.
