Given data

Cost of 5 pencils= $2.50

Required

The cost per pencil

The cost per pencil is

Cost of 5 pencils divided by 5

=2.5/5

=$0.5

This is the constant of proportionality

For any number of pencils x

The cost is

Cost =0.5x

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

Karina is showing her steps to solve the expression −26.7 ÷ 1/3
timama [110]

Step 2: -26.7 · -3

When you divide with a fraction, it's helpful to multiple by the reciprocal of the fraction .

This step instead multiplied by the negative reciprocal .

Therefore, the correct answer would be -80.1 instead of 80.1

The error was made in step 2.
