Which is the equation of the line through the point (−3, 8) that is perpendicular to the line y=14x+12?
Answer:
y = -1/14x + 109/14
Step-by-step explanation:
If two lines are perpendicular to each other, they have opposite slopes.
The first line is y = 14x + 12. Its slope is 14. A line perpendicular to this one will have a slope of -1/14.
Plug this value (-1/14) into your standard point-slope equation of y = mx + b.
y = -1/14x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-3, 8). Plug in the x and y values into the x and y of the standard equation.
8 = -1/14(-3) + b
To find b, multiply the slope and the input of x (-3)
8 = 3/14 + b
Now, subtract 3/14 from both sides to isolate b.
8 - 3/14 = b
112/14 - 3/14 = b
109/14 = b
Plug this into your standard equation.
y = -1/14x + 109/14
This equation is parallel/perpendicular to your given equation (y = 14x + 12) and contains point (-3, 8)
Hope this helps!

Please find the area and perimeter
Answer:
Area: 54 in² Perimeter: 36 inStep-by-step explanation:
Area:
A = 6 in · 10 in - 2 in · 3 in = 60 in² - 6 in² = 54 in²
Perimeter:
P = 2·6 in + 10 in + 6 in + 3 in + 1 in + 2·2 in = 12 in + 20 in + 4 in = 36 in
Dorothy invested $80,000. Some was invested
in high-yield bonds that earned a 10% profit,
and the rest was put into “old economy" stocks
that earned a 12% profit. How much did
Dorothy invest in high-yield bonds if her total
profit on both types of investments was
$9,200?
Answer:
The amount invested in high-yield bonds was $20,000
Step-by-step explanation:
The total amount Dorothy invested = $80,000
The amount that can be earned by investing part of the amount in high-yield bonds = 10% profit
The amount that can be earned by putting the rest of the amount into "old economy" stocks = 12% profit
Dorothy's total profit = $9,200
Let 'x' represent the amount she invested in high-yield bonds, and let 'y' represent the amount she invested in "old economy" stocks, we have;
x + y = 80,000...(1)
0.1·x + 0.12·y = 9,200...(2)
From equation (1), we get;
y = 80,000 - x
Plugging in the above value of 'y' in equation (2), gives;
0.1·x + 0.12·y = 0.1·x + 0.12 × (80,000 - x) = 9,200
0.1·x - 0.12·x + 9,600 = 9,200
-0.02·x = 9,200 - 9,600 = -400
x = -400/(-0.02) = 20,000
x = 20,000
The amount Dorothy invested in high-yield bonds, x = $20,000
(∴ y = 80,000 - x = 80,000 - 20,000 = 60,000
y = 60,000
The amount she invested in old economy stocks, y = $60,000).
The distance from Alison's house to the mailbox is 2/5 mile. The distance from the mailbox to the bus stop is 1/3 mile. What is the total distance from Alison's house to the bus stop? 3/15 11/15 5/6 3/8
Answer:
Option B is correct
Step-by-step explanation:
Given
Distance from Alison's house to the mailbox = [tex]\frac{2}{5}[/tex] miles
Distance from the mailbox to the bus stop [tex]\frac{1}{3}[/tex] miles
The total distance between Alison's house to the bus stop is
[tex]\frac{2}{5} + \frac{1}{3} \\\frac{6+5}{15} \\\frac{11}{15}[/tex]
Hence, option B is correct
Consider the following pair of equations: y = x + 4 y = −5x − 2 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
(-1, 3)
Step-by-step explanation:
to solve using substitution, you have to know the value of either x or y. in this example, they gave you the value of y already: y=x+4.
this means you can substitute the y for (x+4). if we substitute y for (x+4) in the equation y=-5x-2, we get this:
(x+4)=-5x-2
then solve for x
6x=-6
so x=-1
since we know the x value, we can solve for y
y=x+4
y=-1+4
y=3
so the final answer is (-1, 3)
Answer:
(- 1, 3 )
Step-by-step explanation:
Given the 2 equations
y = x + 4 → (1)
y = - 5x - 2 → (2)
Substitute y = x + 4 into (2)
x + 4 = - 5x - 2 ( add 5x to both sides )
6x + 4 = - 2 ( subtract 4 from both sides )
6x = - 6 ( divide both sides by 6 )
x = - 1
Substitute x = - 1 into either of the 2 equations and evaluate for y
Substituting into (1)
y = - 1 + 4 = 3
solution is (- 1, 3 )
A model train is 9 centimeters long. The actual engine is 18 meters long. What is the scale of the model? Tracy has a model train set that is 59 centimeters long. How long would the train be in real life?
Answer:
1 cm : 2m
1 cm = 2m
118m
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
18 / 9 = 2 : 1
59 x 2 = 118

What is the equation of the line that passes through the point (-5, 4) and has a slope of - 3/5
Step-by-step explanation:
Using point slope form ,
=> ( x - (-5) ) m = ( y - 4)
=> x + 5 = -3/5 ( y - 4)
=> 5x + 25 = -3y + 12
=> 5x + 3y + 13 = 0
