7. On the coordinate grid below, show a line that is parallel to y = 2x + 4. 2 5 3 1 2 3 2 -1 4
Answer
the graph of the line parallel to y = 2x + 4 is presented below
The line has the equation y = 2x + 1
Explanation
Any two parallel lines will have the same slopes.
The slope and y-intercept form of the equation of a straight line is given as
y = mx + c
where
y = y-coordinate of a point on the line.
m = slope of the line.
x = x-coordinate of the point on the line whose y-coordinate is y.
c = y-intercept of the line.
So, for y = 2x + 4, the slope is evidently 2
So, any line that we will pick that will be prallel to the given line has to be of the form
y = 2x + c
c, the y-intercept, can then be any number. Let us use an example where c = 1
The equation of a line parallel to y = 2x + 4 is y = 2x + 1
To plot this, we would need to use the intercepts.
when x = 0,
y = 2x + 1
y = 2(0) + 1
y = 0 + 1 = 1
First point of the line is (0, 1)
when y = 0
y = 2x + 1
0 = 2x + 1
2x = -1
Divide both sides by 2
(2x/2) = (-1/2)
x = -0.5
Second point on the line is (-0.5, 0)
We can then plot the line on the coordinate using these two points (0, 1) and (-0.5, 0)
So, the graph of the line parallel to y = 2x + 4 is presented under 'Answer'

If carpeting costs R75,50/m and an entrance hall has a length of 468,cm. Determine the cost of carpenting the hallway?
The cost of carpeting the hallway is Rs. 35,334.
The cost of carpeting is Rs. 7,550 per meter. We have an entrance hall. The length of the entrance hall is 468 cm. We need to find out the total cost of carpeting the hallway.
First of all, we will convert all the quantities to the same units. The length of the entrance hall is 468/100 = 4.68 meters.
The total cost of carpeting the hallway is the product of the length of the hallway and the cost of carpeting per unit length. Let the cost be represented by the variable "C".
C = Rs. 7,550*4.68
C = Rs. 35,334
Hence, the cost of carpeting the hallway is Rs. 35,334.

There are 11571 people in the world as of 2010, and would take about 22 years for that number to reach 50,000 of population.
What is termed as the exponential increase?An exponential function's curve is created by a pattern of data called exponential growth, which exhibits greater increases over time. Linear growth, which is additive, and geometric growth can be contrasted with exponential growth, which is multiplicative (that is raised to a power).Let P stand for the population in 2000 (or any other time period). Considering the equation:
P = 3485e∧0.12t,
The population in 2010 (t = 10 years) would be:
P = 3485e∧0.12×10
P = 3485e∧12
P = 11571
When there are 50,000 people in the population:
50,000 = 3485e∧0.12t,
Solving, by log property.
t = 22 years.
Thus, there are 11571 people in the world as of 2010, and would take about 22 years for that number to reach 50,000.

How much of your bill was for the parking fee?c.How much does it cost to stay at the hotel for 7 nights?d. If your bill was $591, how many nights did you stay at the hotel?
Answer:
(a)y=72x+15
(b)$15
(c)519
(d)8 nights
Explanation:
Let the number of nights which you stay = x
The cost of renting a room for a night =$72
Therefore, the costs for x nights = $72x
If the charge for using its parking lot = c
Then, the total cost, y=72x+c
Part A
When the total bill = $231
x=3 nights
[tex]\begin{gathered} 231=72(3)+c \\ 231=216+c \\ c=231-216 \\ c=15 \end{gathered}[/tex]Therefore, an equation in slope-intercept form that gives your total bill as a function of the number of nights, x is:
[tex]y=72x+15[/tex]Part B
Your packing fee, c=$15
Part C
When the number of nights, x=7
[tex]\begin{gathered} \text{Total Cost,y}=72(7)+15 \\ =504+15 \\ =\$519 \end{gathered}[/tex]Part D
When the total cost, y = $591
[tex]\begin{gathered} 591=72x+15 \\ 72x=591-15 \\ 72x=576 \\ \frac{72x}{72}=\frac{576}{72} \\ x=8 \end{gathered}[/tex]If your bill was $591, you stayed for 8 nights.

Given the function and the graph below, which of the following best describes the continuity, interval of increase and interval of decrease?
Given the function:
[tex]f(x)=(-x-1)^2+3[/tex]As we can see, there is no restriction for x, it can be any real value. Additionally, looking at the graph, we do not see any discontinuity ("jumps" or "holes"). We conclude that the function is always continuous.
The vertex of the parabola is at (-1, 3), so x = 1 separates the intervals of increase and decrease. Going from -∞ to -1, we see a decrease in the y-values. Similarly, from -1 to +∞, we see an increment. Then:
Interval of increase: -1 < x < +∞
Interval of decrease: -∞ < x < -1

solving right triangle find the missing side. round to the nearest tenth number 15
To solve the triangle we are going to first find the measures of all the angles:
[tex]\begin{gathered} A=47\text{\degree} \\ B=90\text{\degree}\Rightarrow\text{ Because is a right triangle} \\ A+B+C=180\text{\degree} \\ \text{Because the sum of the internal angles of a triangle is 180 degrees} \\ 47\text{\degree}+90\text{\degree}+C=180\text{\degree} \\ 137\text{\degree}+C=180\text{\degree} \\ \text{ Subtract 137\degree from both sides of the equation} \\ 137\text{\degree}+C-137\text{\degree}=180\text{\degree}-137\text{\degree} \\ C=43\text{\degree} \end{gathered}[/tex]Now to find the measures of the sides you can use trigonometric ratios because it is a right triangle:
Side a: you can use the trigonometric ratio tan(θ)
[tex]\tan (\theta)=\frac{\text{ opposite side}}{\text{adjacent side}}[/tex][tex]\begin{gathered} \tan (47\text{\degree})=\frac{a}{28} \\ \text{ Multiply by 28 from both sides of the equation} \\ \tan (47\text{\degree})\cdot28=\frac{a}{28}\cdot28 \\ 30=a \end{gathered}[/tex]Side b or side x: you can use the trigonometric ratio cos(θ)
[tex]\cos (\theta)=\frac{\text{adjacent side}}{\text{hypotenuse}}[/tex][tex]\begin{gathered} \cos (47\text{\degree})=\frac{28}{b} \\ \text{ Multiply by b from both sides of the equation} \\ \cos (47\text{\degree})\cdot b=\frac{28}{b}\cdot b \\ \cos (47\text{\degree})\cdot b=28 \\ \text{ Divide by cos(47\degree) from both sides of the equation} \\ \frac{\cos (47\text{\degree})\cdot b}{\cos (47\text{\degree})}=\frac{28}{\cos (47\text{\degree})} \\ b=\frac{28}{\cos(47\text{\degree})} \\ b=41.1 \end{gathered}[/tex]Therefore, when solving the triangle you have
[tex]\begin{gathered} A=47\text{\degree} \\ B=90\text{\degree} \\ C=43\text{\degree} \\ a=30 \\ b=41.1 \\ c=28 \end{gathered}[/tex]and the missing side is

Before we begin we will order the data set given
4, 6, 7, 9, 10, 11, 11, 12, 15, 16
Mean.
The mean of a data set is given by:
[tex]\operatorname{mean}=\frac{\sum ^{}_{}x_i}{n}[/tex]where the denominator means that we have to add the points on the data and then divide them result by the number of points in the data. In this case we have:
[tex]\begin{gathered} \operatorname{mean}=\frac{4+6+7+9+10+11+11+12+15+16}{10} \\ \operatorname{mean}=\frac{101}{10} \\ \operatorname{mean}=10.1 \end{gathered}[/tex]Hence the mean of the data set is 10.1
Median.
The median is the central value of the ordered data set. In this case we have an even number of values which means that the median is the average of the central values. The central values in this set are the the fifth and sixth term, that is, 10 and 11. The median is then:
[tex]\begin{gathered} \operatorname{median}=\frac{10+11}{2} \\ \operatorname{median}=\frac{21}{2} \\ \operatorname{median}=10.5 \end{gathered}[/tex]Mode
The mode is value that occur most frequently. In this case only the 11 repeats itsefl, hence the mode is 11.
Summing up we have:
Mean 10.1
Median 10.5
Mode 11
