Consider the formula for the slope between two coordinates
krek1111 [17]

The following equations is equivalent to the slope formula is A) y₂= m(x₂-x₁) + y₁.

<h3>What is slope?</h3>

The angle of inclination of a line with respect to the horizontal is quantified. In analytical geometry, a line, ray, or line segment's slope is the proportion of the vertical to the horizontal distance between any two points ("slope equals rise over run").

<h3>What is equation?</h3>

Two expressions are combined by the equal sign to form a mathematical statement known as an equation. For instance, a formula might be 3x - 5 = 16. We discover that the variable x has a value of 7 after solving this equation.

Given that,

Take a look at the formula below for the slope between two coordinate locations, m.

m = \frac{y_{2}- y_{1} }{x_{2}-x_{1}  }

Here, slope is

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Where m is the slope and y₁ and y₂ and x₁ and x₂ are coordinates of the axis.

The first step is to multiply x₂-x₁ on both sides in order to acquire y₂ on its own.

so you must add y₁ to both sides in order to get y₂ alone.

m(x₂-x₁) +y₁ = y₂.

Therefore, the following equations is equivalent to the slope formula is A) y₂ = m(x₂-x₁) + y₁.

I need help with this promblem it’s ALGEBRA 2!
AlekseyPX

Answer:

(f\circ h)(2)=2

Step-by-step explanation:

<u>Composite Function </u>

Given f(x) and h(x) real functions, the composite function named (f\circ h)(x) is defined as:

(f\circ h)(x)=f(h(x))

It can be found by substituting h into f.

We are given the functions:

f(x)=2x^2-9x+2

h(x)=x^2-4

It's required to find (f\circ h)(2)

As defined above:

(f\circ h)(x)=f(h(x))

Thus:

(f\circ h)(2)=f(h(2))

Find h(2):

h(2)=2^2-4=0

h(2)=0

Now:

(f\circ h)(2)=2(0)^2-9(0)+2

(f\circ h)(2)=2
