Answer:
y = − 2 x
Step-by-step Explanation:
Y + 2 = − 2 ⋅ ( − 1 ) Write in y = m x + b form.
The equation of a perpendicular line must have a slope that is the negative reciprocal of the original slope.
m in perpendicular = − 1 2
(1,-2),y=(1)/(2)x+4

Answer:
y = -2x + 8
Step-by-step explanation:
For this problem we need to consider that the equation of a line perpendicular to another line will have a "negative reciprocal" slope so that when they cross, it forms a 90-degree angle, hence perpendicular. Additionally, we will need to use the point-slope form and re-write it into the slope-intercept form to incorporate (2,4) into our equation. With these things in mind, let's do that.
y = (1/2)x + (1/2)
We want a "negative reciprocal" so:
y = -2x + (1/2)
Since -2 is the "negative reciprocal" of 1/2.
And now we want to use the point-slope form to incorporate (2,4)
y - y0 = -2 ( x - x0 )
Where, y0 = 4 and x0 = 2.
y - y0 = -2 ( x - x0 )
y - 4 = -2 ( x - 2 )
y - 4 = -2x + 4
y = -2x + 8
So, the equation that is perpendicular to y = (1/2)x + (1/2) and includes the point (2,4) is y = -2x + 8.
Cheers.

[tex] - 3(2a - 14) - 3a = 24[/tex]
[tex] - 6a + 42 - 3a = 24[/tex]
[tex] - 9a + 42 = 24[/tex]
Subtract sides 42
[tex] - 9a + 42 - 42 = 24 - 42[/tex]
[tex] - 9a = - 18[/tex]
Divide sides by - 9
[tex] \frac{ - 9a}{ - 9} = \frac{ - 18}{ - 9} \\ [/tex]

Suppose you are told that 1/2 = 3' on a scale drawing. If there is an object that measures 5" in the drawing, what would its actual length be?
Scale drawings are used to represent a large drawing using smaller measurements
The equivalent of 5" in the drawing is 30' i.e. 30 feet
The scale is given as:
[tex]\mathbf{\frac 12" = 3'}[/tex]
A single quote means feet, while a double quote means inches
So, the scale can be rewritten as:
[tex]\mathbf{\frac 12\ inches= 3\ feet }[/tex]
Multiply both sides by 10
[tex]\mathbf{\frac 12\ inches \times 10 = 3\ feet \times 10}[/tex]
Simplify
[tex]\mathbf{5\ inches = 30\ feet }[/tex]
Rewrite as:
[tex]\mathbf{5" = 30'}[/tex]
Hence, the equivalent of 5" in the drawing is 30' i.e. 30 feet

What is the average rate of change of f over the interval -7 < or equal to x
Give an exact number
Answer:
[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
The average rate of change can be found by using the following formula
[tex]\frac{f(x_{2}) - f(x_{1}) }{x_{2} - x_{1}}[/tex]
Since the interval goes from -7 to 2, we should find the y-values that correspond to x=-7 and x=2.
By inspection of the graph, we can clearly see that when x is -7, y is -7 as well and when x is 2, y is 5.
Now that we know this, we can simply plug these values into the formula!
[tex]\frac{f(2) - f(-7) }{2 - (-7)} = \frac{5 - (-7)}{2 - (-7)} = \frac{5 +7}{2+7} = \frac{12}{9} = \frac{4}{3}[/tex]
Good luck!
Does the point (-3,-1) lie on the line with the equation y = 10 - 3x ? Be sure to show your work.
Replace x in the equation with the x value from the point and solve. If the equation equals the y value from the point the point lies in the line, if it doesn’t equal the y value then it doesn’t lie on the line.
Y = 10 -3(-3) = 10 + 9 = 19
19 doesn’t equal -1 so the point does not lie on the line.

2. When Deema begins her drive, she is 400 mi from home. She drives at an average rate of 50 mph until she gets
home. Draw a graph to represent this situation?
Answer: I can give coordinates (0,400) (1,350) (2,300) (3,250) (4,200) (5,150) (6,100) (7,50) (8,0)
Step-by-step explanation:
Deema starts at 400 which is y-intercept and goes down on a slope of -50 cause we are decreasing 50 mi for every hour she drives.

Total distance traveled by Deema = 400 miles
The average speed of Deema = 50 mph
In each 1 hour, 50 miles of distance will be covered
So by the rate of 50 miles per hour the coordinates in this situation are given as follows
Time (X axis) Distance (Y axis)
0 400
1 350
2 300
3 250
4 200
5 150
6 100
7 50
8 0
