No, that does not make sense. When you subtract, you add the opposite. That means you’re adding two positive numbers. When you a

dd two positive numbers, the result is positive.

NeX [460]

Total number of friends = 3

Let the fare be = $ J

As it is equally divided, each friend has to pay $\frac{J}{3}$ amount

Angela paid $5 additional as tip so her share is $\frac{J}{3}+5$

Hence,Angela paid $ $\frac{J}{3}+5$ in total.

Model the data using an exponential function f(x) = Abx. HINT [See Example 1.]

zlopas [31]

We take the function as a sequence

Term 1 ⇒ 5
Term 2 ⇒ 4
Term 3 ⇒ 3.2

Between terms, there is a common ratio of ⁴/₅
We get it from here:
Term 2 / Term 1 = $\frac{4}{5}$
Term 3 / Term 2 = $\frac{3.2}{4}$ = $\frac{4}{5}$

When a sequence has a common ratio between term, the sequence is a Geometric Sequence

$n_{th}term=ar^{n-1}$
Where $a$ is the first term, $r$ is the common ratio, and $n$ is the term number

We have: $a=5$ and $r= \frac{4}{5}$
The formula for the function is

$f(x)=5( \frac{4}{5})^{x-1}$

A taxi charges $20 flat fee for the first 5 miles (even if it takes the rider one mile the cost is $20) and after that the addit

Free_Kalibri [48]

Ok so, we have the fact that 1.20 per mile Lets represent m as each additional mile so we have 1.20m which is That much per additional mile So For the first 5 functions we have f(1) = 20 f(2) = 20 f(3) = 20 f(4) = 20 f(5) = 20 Only for the first 5 miles though, since it is a flat fee. So for the additional miles we go back to what I said in the first Paragraph. 1.20m That is for additional miles, so that will be added to 20 So if you travel more than 5 miles the function looks like this: f(x) = 20 + 1.20m So the first 5 miles it is: f(x) = 20 For 7 mles the function would look like: f(7) = 20 + 1.20(2) It is a 2 because it is the additional mile, which is 2 hope this helps

Si el área de una figura rectangular esta dada por A-bxh,¿cual es la siguiente expresiones representa el área de la puerta

stealth61 [152]

Respuesta:

3x² + 5x - 2

Explicación paso a paso:

Dado que :

Área del rectángulo, A = largo * ancho

Dimensión = 3x - 1; x + 2

Área = (3x - 1) * (x + 2)

Área = 3x² + 6x - x - 2

Área = 3x² + 5x - 2
