Answers
Answer:
a. ST and UV are perpendicular lines.
b. BC and DE are parallel.
c. NP and QR are neither parallel nor perpendicular.
d. GH and JK are parallel.
Step-by-step explanation:
Slopes are used to calculate steepness of a line. Slopes are also used to check if two lines are parallel, perpendicular or neither.
When two lines are parallel, their slopes are equal.
When two lines are perpendicular, product of slopes of both lines is -1
Slope is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
a) S(-4, -1), T(-1,5) and U(1,1), V(5, -1)
[tex]Slope\ of\ ST = \frac{5+1}{-1+4} = \frac{6}{3} = 2\\Slope\ of\ UV = \frac{-1-1}{5-1} = \frac{-2}{4} = -\frac{1}{2}[/tex]
Now,
[tex](Slope\ of\ ST)(Slope\ of\ UV) \\= 2 * -\frac{1}{2}\\=-1[/tex]
ST and UV are perpendicular lines.
b) B(-6, -2), C(-3, 3) and D(2,0), E(5,5)
[tex]Slope\ of\ BC = \frac{3+2}{-3+6} = \frac{5}{3}\\Slope\ of\ DE = \frac{5-0}{5-2} = \frac{5}{3}[/tex]
As the slopes of two lines is equal, BC and DE are parallel.
c) N(-6,2), P(--3, -4) and Q(1, -3), R(3, 4)
[tex]Slope\ of\ NP = \frac{-4-2}{-3+6} = \frac{-6}{3} = -2\\Slope of\ QR = \frac{4+3}{3-2} = \frac{7}{2}[/tex]
NP and QR are neither parallel nor perpendicular.
d) G(-2,5), H(4,1) and J(1, –4), K(7,0)
[tex]Slope\ of\ GH = \frac{1-5}{4+2} = \frac{-4}{6} = -\frac{2}{3}\\Slope\ of\ JK = \frac{0-4}{7-1}= \frac{-4}{6} = -\frac{2}{3}[/tex]
GH and JK are parallel.
Hence,
a. ST and UV are perpendicular lines.
b. BC and DE are parallel.
c. NP and QR are neither parallel nor perpendicular.
d. GH and JK are parallel.

Go to your math tools and open the Graph tool to graph Gwen's and Tristan's equations. Hint: To create the graph, select the correct relationship
and then enter the values for the variables. You will need to change the scales for the x- and y-axes. When deciding the scale, ask yourself what x
and y stand for, and what would be reasonable amounts for their minimum and maximums.
Do the two lines intersect? Why or why not? What does this mean in terms of the situation? If the lines intersect, at what point do they intersect
and what does this point mean in terms of the situation? Paste a screenshot of your graph in the space provided.
I just need help on graphing the equation I can take the screen shot my self. The equation for Gwen is Y = 100+10x
The equation for Kieth is Y = 10x
The equation for Tristan is Y = 12.5x
Answers
Answer:
Step-by-step explanation: when you first open the graphing tool you have to click relationship and choose custom. put in gwen’s equations (y=100+10x) then go to relationship and choose custom again and put in tristan’s equation (y=12.5)
also click on the settings button at the bottom of the graph and put the x axis to -100 min and 100 max and for y axis put -1000 min and 1000 max or you could choose your own numbers but thats just what i put
The graph of the equations (y = 10x + 100), (y = 10x), and (y = 12.5x) can be drawn by using the rules of transformation.
Given :
y = 100 + 10xy = 10xy = 12.5xThe following steps can be used to sketch the graph of the given line (y = 100 + 10x):
Step 1 - First sketch the graph of (y = x).
Step 2 - Then Multiply the x-axis by a factor of 10. The resulting graph is the graph of (y = 10x)
Step 3 - Then find the y-intercept from the given equation. Then draw the line that passes through (0,100). The resulting line is the graph of (y = 100 + 10x).
The following steps can be used to sketch the graph of the given line (y = 10x):
Step 1 - First sketch the graph of (y = x).
Step 2 - Then Multiply the x-axis by a factor of 10. The resulting graph is the graph of (y = 10x)
The following steps can be used to sketch the graph of the given line (y = 12.5x):
Step 1 - First sketch the graph of (y = x).
Step 2 - Then Multiply the x-axis by a factor of 12.5. The resulting graph is the graph of (y = 12.5x)
The graph of all the equations together is attached below.
Red line shows the graph of (y = 10x + 100).Blue line shows the graph of (y = 10x)Green line shows the graph of (y = 12.5x)For more information, refer to the link given below:

The value of the function g(x) is −2 when x=−5 and is 5.7 when x=6. What is the equation for the function g(x)?(1 point)
Answers
Given:
The value of the function g(x) is −2 when x=−5 and is 5.7 when x=6.
To find:
The equation of the function.
Solution:
The value of the function g(x) is −2 when x=−5. It means the graph of function passes through (-5,-2).
The value of the function g(x) is 5.7 when x=6. It means the graph of function passes through (6,5.7).
The equation of function g(x) that passes through (-5,-2) and (6,5.7) is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-(-2)=\dfrac{5.7-(-2)}{6-(-5)}(x-(-5))[/tex]
[tex]y+2=\dfrac{5.7+2}{6+5}(x+5)[/tex]
[tex]y+2=\dfrac{7.7}{11}(x+5)[/tex]
[tex]y+2=0.7(x+5)[/tex]
[tex]y+2=0.7x+3.5[/tex]
Subtract 2 from both sides.
[tex]y=0.7x+3.5-2[/tex]
[tex]y=0.7x+1.5[/tex]
Therefore, the equation of function g(x) is [tex]y=0.7x+1.5[/tex].

Anand needs to hire a plumber. He's considering a plumber that charges an initial fee of $65 along with an hourly rate of $28. The plumber only charges for a whole number of hours. Anand would like to spend no more than $250, and he wonders how many hours of work he can afford.
Let H represent the whole number of hours that the plumber works.
1) Which inequality describes this scenario?
Choose 1 answer:
A) 28 + 65H ≤ 250
B)28 + 65H ≥ 250
C) 65 + 28H ≤ 250
D) 65 + 28H ≥ 250
2) What is the largest whole number of hours that Anand can afford?
hours
Answers
Answer
1.) B
2.) 3 hours
Step-by-step explanation:
1.) option B is correct I think because it shows he will either be equal to or less than how much money he wants to spend
2.) i got three because if you sent up the equal I picked in question one then you subtract 28 from 250 giving u 222 and you divide that by 65 giving you 3.4 but he only charges by the whole hour so that .4 of an hour he wouldn't charge you for

Consider the following vectors in polar form.

What is the magnitude of vector w, if w = u – v?
|w| = 2.77
|w| = 2.95
|w| = 3.58
|w| = 5.60
Answers
Answer:
B 2.95
Step-by-step explanation:
The magnitude of w is |w| = 2.95 , Option B is the correct answer.
What is a Vector ?Any object that has both magnitude and direction is called a Vector.
It is given that
|u| = 2 at 0 degree
|v| = 4 at 45 degree
The magnitude of the vector w = | u -v| = ?
The resultant angle will be 45 degree
By applying Cosine law
w = | u -v| = [tex]\rm \sqrt { u^2 + v^2 - 2*u*v*cos \theta}[/tex]
w = | u -v| = [tex]\rm \sqrt { 2^2 + 4^2 - 2*2*4*cos 45^o}[/tex]
w = 2.947 = 2.95
Therefore the magnitude of w is |w| = 2.95 , Option B is the correct answer.
