If f(x)=4x-2 and g(x)=-8x+7, find h(x)=f(x) - g(x)

user100 [1]

Answer:

$h(x)=12x-9$

Step-by-step explanation:

We are given the two functions:

$f(x)=4x-2\text{ and } g(x)=-8x+7$

And we want to find:

$h(x)=f(x)-g(x)$

So, by substitution:

$h(x)=(4x-2)-(-8x+7)$

Simplify. Distribute:

$h(x)=(4x-2)+(8x-7)$

Rearrange:

$h(x)=(4x+8x)+(-2-7)$

Combine like terms. Hence:

$h(x)=12x-9$

Tina was asked to determine the possible dimensions of a given rectangle whose area is 12a4b3-18a6b3-72a7b3. Tina stated that th

Rufina [12.5K]

Answer:

Tina is correct

Step-by-step explanation:

Given

$Area = 12a^4b^3 - 18a^6b^3 - 72a^7b^3$

Required

State if $3a^4b^3(4-6a^2-24a^3)$ is a possible dimension

To do this, we simply expand $3a^4b^3(4-6a^2-24a^3)$

$3a^4b^3(4-6a^2-24a^3)$

$3a^4b^3 * 4-3a^4b^3 * 6a^2-3a^4b^3 * 24a^3$

$12a^4b^3 - 18a^{4+2}b^3 * -72a^{4+3}b^3$

$12a^4b^3 - 18a^{6}b^3 * -72a^{7}b^3$

By comparison, the result of the expansion

$12a^4b^3 - 18a^{6}b^3 * -72a^{7}b^3$

and the given expression

$Area = 12a^4b^3 - 18a^6b^3 - 72a^7b^3$

are the same.

<em>Hence, Tina is correct</em>
