Sophie [7]

Number of ounces left is 1120

Step-by-step explanation:

Step 1: Find number of ounces left after each day.

Given total soup prepared each day = 15 gallons

Amount served each day = 1/4 of 15 = 15/4 gallons

Amount left after each day = 15 - 15/4 = 60 - 15/4 = 35/4 gallons

Step 2: Convert gallons into ounces. 1 gallon = 128 ounces

35/4 gallons = 35/4 × 128 = 1120 ounces

A 3-mi cab ride costs $7.30. A 8-mi cab ride costs $15.30. Find a linear equation that models a relationship between cost c and

Rus_ich [418]

Answer:

Option c) $c=1.60d+2.5$

Step-by-step explanation:

Let

d -----> the distance in miles

c ----> the cost in dollars

we have the ordered pairs

(3,7.30) and (8,15.30)

step 1

Find the slope of the linear equation

The slope is equal to

$m=\frac{15.30-7.30}{8-3}$

$m=\frac{8}{5}$

step 2

Find the equation of the line in point slope form

$c-c1=m(d-d1)$

we have

$point\ (3,7.30)$

$m=\frac{8}{5}$

substitute

$c-7.30=\frac{8}{5}(d-3)$

$c=\frac{8}{5}d-\frac{24}{5}+7.30$

$c=1.60d+2.5$

F ( x ) = x − 3 x , g ( x ) = x + 3 , h ( x ) = 2 x + 1 , ( g ⋅ h ⋅ f ) ( x )

DiKsa [7]

Composing functions just means to feed the ouput of the inner one as the input for the outer one.

So, the following writings are equivalent:

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

Using the second form, we can see that the first thing to do is to compute $f(x)$ , which is given:

$f(x) = x-3$

This means that we can update the fomula:

$(g\circ h \circ f)(x) = g(h(f(x))) = g(h(x-3))$

So, now we have to compute $h(x-3)$ . Given $h(x)=2x+1$ , we know that $h$ doubles the input and adds one. In this case, the input is $x-3$ , so we have to double this and add one:

$h(x-3) = 2(x-3)+1 = 2x-6+1 = 2x-5$

So, we have

$(g\circ h \circ f)(x) = g(h(f(x))) = g(2x-5)$

Similarly, from $g(x) = x+3$ , we understand that $g$ just adds 3 to the input. In this case, the input is $2x-5$ , so we'll add 3 to this quantity:

$g(2x-5) = (2x-5)+3 = 2x-2$

So, we finally have

$(g\circ h \circ f)(x) = g(h(f(x))) = 2x-2$
