Answer:

Step-by-step explanation:

from the graph of f(x)

when x=1,f(x)=0

or f(1)=0

when f(x)=2,x=2

for g(x)

when x=6,g(x)=16

or g(6)=16

when g(x)=18,x=32

for h(x)

when x=14

h(x)=27x-7

h(14)=27×14-7=7(27×2-1)=7(54-1)=7×53=371

h(x)=-493

27x-7=-493

27 x=-493+7=-486

3 x=-54

x=-18

for p(t)

when t=94

p(t)=24

p(94)=24

p(t)=67

t=31

Christian reads 14 book every 23 week.

mihalych1998 [28]

Picture 1: The amount of tax for Veena's meal is $1.02

Picture 2: Christian reads $\frac{3}{8}$ books per week.

Picture 3: 80% is equal to $\frac{4}{5}$ .

Step-by-step explanation:

Picture 1: Veena ate lunch at a deli. She ordered turkey sandwich for $9.25 and a salad for $4.35. The tax was 7.5%. What is the amount of tax for Veena's meal.

Given,

Price of turkey sandwich = $9.25

Price of salad = $4.35

Total amount = 9.25+4.35 = $13.60

Tax = 7.5%

Amount of tax = 7.5% of total cost

Amount of tax = $\frac{7.5}{100}*13.60$

Amount of tax = $\frac{102}{100} = \$1.02$

The amount of tax for Veena's meal is $1.02

Picture 2: Christian reads 1/4 book every 2/3 week. How many books does Christian read per week?

Given,

Books read every 2/3 weeks = 1/4 books

$\frac{2}{3}\ weeks=\frac{1}{4}\ books\\$

For determining the number of books read per week, we will multiply both sides by $\frac{3}{2}$

$\frac{3}{2}*\frac{2}{3}\ week=\frac{1}{4}*\frac{3}{2}\ books\\\\1\ week = \frac{3}{8}\ books\\\\$

Christian reads $\frac{3}{8}$ books per week.

Picture 3: What percent is equivalent to $\frac{4}{5}$ ?

We will multiply the given fraction with hundred for calculating the percentage.

$\frac{4}{5}*100\\\\\frac{400}{5}\\\\80\%$

Therefore,

80% is equal to $\frac{4}{5}$ .

What is the average (arithmetic mean) of all the multiples of ten from 10 to 190 inclusive?

NeX [460]

Answer:

letter C: 100

Step-by-step explanation:

This problem can be configured as an arithmetic progression:

The first value is 10, the ratio is also 10 (the multiples of ten are 20, 30, 40, ...) and the number of terms is 19 (10, 20, 30, ... , 180, 190 -> total of 19 numbers).

So, we can use the following formula to calculate the sum of all these numbers:

Sn = n(a1 + an) /2

where Sn is the sum, n is the number of terms, a1 is the first term and an is the last one.

The result we want is the average of the sum, so we need to divide Sn by n:

Average = Sn/n = n(a1 + an) /2n = (a1 + an) /2 = (10+190)/2 = 200/2 = 100

The correct option is letter C.

Pls help w/ algebra

AlladinOne [14]

<h3>Answer:</h3>

See attached graphs.

<h3>Step-by-step explanation:</h3>

You are being asked to observe the graphs of the various equations and identify something they have in common. To answer the question, it usually works well to do exactly what the question asks you to do.

a: All three lines have a slope of at least 1 and pass through the origin.

b: These lines all have the same slope. They are parallel.

c: All three lines have a slope less than 1 and pass through the origin.

d: These are all the same line.

e: All of these lines intersect at the point (2, -2).

<em>Comment on the graphs</em>

The number of attachments allowed here is limited, so some graphs have been combined. Where there are 3 lines, the first is red, the second is blue, the third is green.

Graphs for (a) and (c) appear on the same page. The graphs for (c) are shown as dashed lines.

Graphs for (b) and (d) appear on the same page. The graph for (d) is shown in orange (as a dashed line). All threee lines look exactly like this.

<em>Comment on the graphing program</em>

These are graphed using the Desmos on-line graphing calculator. It has a tutorial available and is not difficult to learn for most simple graphing applications. (It prefers the variables x and y.) Graphs can be saved for later. (Here, screen shots are used because Brainly doesn't like external links.)
