what is the domain of the function f(x)=6x+3
Answer:
All Real Numbers
Step-by-step explanation:
This is a linear function, so the domain is All Real Numbers, or (-∞, ∞). In other words, the all numbers on the x-axis are defined on the graph. We have no points where x is undefined or imaginary. Domain contains all real numbers.

A family of five went out to dinner at HogTastic Pit BBQ. They all ordered the buffet and drink at $12.80 each. They left a 15% gratuity for the waitress on the after-tax bill. Based on a tax rate of 7.5%, they ended up paying a total of $ blank
for dinner.
Answer: $79.12
Step-by-step explanation:
[tex]$$5 peopleeach order is worth \$12.80$$\begin{aligned}\therefore \text { Total bill } &=12.80 \times 5 \\&=64 \$\end{aligned}$$[/tex]
[tex]${Tax}: 7.5 \%$$\therefore$ Bill after tax$$\begin{aligned}&=64\left(\frac{100+7.5}{100}\right) \\&=64(1.075) \\&\text{Bill \ with \ tax}=68.8 \$$\end{aligned}$$[/tex]
[tex]$$Gratuity$=15 \%$ of bill with tax$$\begin{aligned}\therefore \text { Gratuity} &=0.15 \times 68.8 \\&=10.32 \$\end{aligned}$$$\therefore$ Ended up paying a total of $=68.8+10.32$$$\ \ \ \ \ \ \ \ \ \ =\$79.12 $$[/tex]

Mr. Whitman gave a test to his 32 math students. He felt the results were low, so he retested them one week later. The results of the original and retake test are shown below.
A. What is the difference in the median grade?
B. Compare the percent of students who got at least a 60 on the original test to those that got at least a 60 on the retake.
C. If the students need a 65 in order to pass the test, how many more passed the retake?
The number of student more passed the retake, when the students need a 65 in order to pass the test is 8.
What is box and whiskers plot?Box plot is the way of representation of data which gives the graphical image of the data set to understand better. In this the data is represented with the help of quartile.
A.The difference in the median grade-The median of first test is 60 while the second test is 80. Thus, the difference is,
[tex]d=80-60\\d=20[/tex]
B. Compare the percent of students who got at least a 60 on the original test to those that got at least a 60 on the retake.The student, who got at least 60 in first test, falls in the second half of the plot. Thus, the 50% of students got atleast 60% marks. In the retake test, all 100% student got at least 60 on test.
C. If the students need a 65 in order to pass the test, how many more passed the retake?In the first test 1/4 are passed while in second test 3/4 students are passed and got the marks 65 or more than this, Thus the number of student pass more in this test,
[tex]n=(\dfrac{3}{4}-\dfrac{1}{2})\times 32\\n=8[/tex]
Thus, the number of student more passed the retake, when the students need a 65 in order to pass the test is 8.

The area of a rectangle is 72 square inches. The length is
12 inches. What is the width?
Answer: 6 inches
Step-by-step explanation: the area of a rectangle is width times length, that is [tex]A = w.l[/tex]
In this case we have:
Area A = 72 square inchesWidth w = 12 inchesSo to get the Lenght l we need to divide [tex]l = \frac{A}{w}[/tex]
[tex]l = \frac{72}{12}[/tex]
[tex]l = 6[/tex]

Answer:
rounded to the nearest whole number = 166
Step-by-step explanation:
Add all of the angles together, to get 39x. In a hexagon, all the angles add up to 720. Divide 720 by 39 to get x, then multiply x by 9, as that is the largest angle to get an answer rounded to the nearest whole number of 166.

Answer:
54=x
Step-by-step explanation:
2x+2=3x-52
this is because they are opposite alternating angles so now we can re arrange the equation.
54=x
Step-by-step explanation:
The both angles are vertically opposite angle so
[tex](2x + 2) = (3x - 52)[/tex]
By moving x on left side
[tex]2x - 3x = - 52 - 2[/tex]
So
[tex] - x = - 54[/tex]
Negative sign in both side are canceled so we got

Suppose the goal is to raise $600. One equation relating the calendar and poster sales to the $600 goal is 3c + 2p= 600. Suppose the company donating the calendars and posters said they would provide a total of $250 items.
Answer:
100 calendars and 150 postersStep-by-step explanation:
Note it seem the "$" shouldn't be in front of 250 as it is the numbe of itemsa) The second equation is
c + p = 250b) The graph of both equations is attached
The intersection point of the lines is (100, 150)
It indicates 100 calendars and 150 posters to be donated to meet both of targets $600 and 250 items.
Answer:
Given equation:
[tex]3c+2p=600[/tex]
where:
c = number of calendarsp = number of postersPart (a)If the company donating the calendars and posters said they would provide a total of 250 items then:
[tex]c+p=250[/tex]
Part (b)To graph:
Rewrite both equations to make p the subjectFind the c-interceptFind the p-interceptConnect the two points with a straight line[tex]3c+2p=600 \implies p=300-\dfrac{3}{2}c[/tex]
[tex]\textsf{x-intercept}: \quad 300-\dfrac{3}{2}c=0 \implies c=200 \implies (200,0)[/tex]
[tex]\textsf{y-intercept}: \quad 300-\dfrac{3}{2}(0)=300 \implies (0,300)[/tex]
[tex]c+p=250 \implies p=250-c[/tex]
[tex]\textsf{x-intercept}: \quad 250-c=0 \implies c=250 \implies (250,0)[/tex]
[tex]\textsf{y-intercept}: \quad 250-0=250 \implies (0,250)[/tex]
Point of intersection (equate equations):
[tex]\begin{aligned}300-\dfrac{3}{2}c &=250-c\\50 & =\dfrac{1}{2}c\\ c & =100\end{aligned}[/tex]
[tex]p=250-100=150[/tex]
[tex]\implies \left(100,150}\right)[/tex]
The point of intersection tells us that they need to sell 100 calendars and 150 posters to reach their goal of raising $600. Therefore, the company needs to provide 100 calendars and 150 posters (or 250 items in the ratio of calendars to posters of 2 : 3).

Answer:
310 yd
Step-by-step explanation:
Perimeter = distance all the way around the outside of a 2D shape
Missing vertical length = 22 + 27 + 15 = 64
⇒ perimeter = 59 + 22 + 32 + 27 + 32 + 15 + 59 + (22 + 27 + 15)
= 59 + 22 + 32 + 27 + 32 + 15 + 59 + 64
= 310 yd
