Answer:

y = 4x + x is a linear equation

Step-by-step explanation:

A linear equation has the general equation as below;

${ \bf{y = mx + k}}$

k is a constant.

• For y = 4x + x

y = 5x

m is 5 and k is 0

If f(x) = 2x – 1 and g(x) = ^ – 2, find [g ◦ f](x).

Viefleur [7K]

Answer:

<em> The value of [g ◦ f](x) = $4x^{2} -4x-1$ </em>

Step-by-step explanation:

If f(x) = 2x - 1

g(x) = $x^{2} -2$

we need to find the value of [g ◦ f](x).

which means that g(f(x))

g(f(x)) = $(2x-1)^{2} -2$

g(f(x)) = $4x^{2} -4x+1 -2$

g(f(x)) = $4x^{2} -4x-1$

<em> The value of [g ◦ f](x) = $4x^{2} -4x-1$ </em>

The taxi fare in Gotham City is $2.40 for the first 1/2 mile and additional mileage charged at the rate $0.20 for each additiona

Troyanec [42]

3.3 miles should be the answer
10 = 2.40 + .2x    - take 2.4 from both sides
7.6 = .2x    - take 2 from 7.6 for the tip
5.6 = .2x    - divide both sides by .2
28 = x
this means that you can pay the taxi drives an additional 28 times with the .20 cents fee and still have 2 dollars left over
now multiply 28 by .1 miles which is 2.8 miles
add 2.8 miles to .5 miles which equals 3.3 miles
