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).

Answer:

Step-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

Answer:

y= -9/5x -7

y= -3x +2

y= 45/7

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 )

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

Answer:

here is the answer as I believe it is correct

1.) 3/2

Answer:

73.5 in^2

Step-by-step explanation:

Given data

Dimension of square= 3.5 inches

Area= 3.5^2

Area= 12.25 in^2

Number of square= 6

Hence the total area is

=12.25*6

=73.5 in^2

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!

(3, 29)

b)  y = 8x + 5

c)  101 thousand

Step-by-step explanation:

slope m = (29-5)/(3-0) = 24/3 = 8

y-intercept = (0, b) = (0, 5)

y = mx + b

y = 8x + 5

2014 - 2002 = 12

y = 8(12) +5
