Answer:

48 is the answer..........

Answer:

d = -4

Step-by-step explanation:

3d – 4 + d = 8d – (-12)

3d - 4 + d = 8d + 12

4d - 4 = 8d + 12

(4d - 4d) - 4 = (8d - 4d) + 12

-4 = 4d + 12

-4 - 12 = 4d (+ 12 - 12)

-16 = 4d

-16/4 = 4d/4

d = -4

Answer:

d= -4

Step-by-step explanation:

3d- 4 +d = 8d + 12

4d - 4 = 8d + 12

4d = 8d + 16

-4d = 16

d= -4

Check

-12 - 4 - 4 = -32 + 12

-20 = -20

Answer:

$8000

Step-by-step explanation:

Let it be that investment in A is x dollars, then Jim invested in B x+3000.

x/100*8=0.08x- the profit from A, (x+3000)/100*7= 0.07x+210

0.08x+0.07x+210=960

0.15x=750

x=750/0.15= 5000

5000+3000=8000dollars- investment in B

The required amount invested in Fund A is $5000, and in Fund B is $8000.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Let the amount invested in fund A be x, and the amount invested in fund b be y.
x  = y - 3000 - - - - - -  - - - - -(1)

0.08x + 0.07y = 960 - - - - - - - - (2)

From the equation, 1
[y - 3000]0.08 + 0.07y = 960
y = $8000

Now,
x = 8000 - 3000
x = 5000

Thus, the required amount invested in Fund A is $5000, and in Fund B is $8000.

Answer:

Sara has enough money to buy all three items because after the sale and tax, the total of all three items is less than $100 at only $93.01.

Step-by-step explanation:

Solve for the sale:

43.98 × 0.25

10.995

38.59 × 0.25

9.6475

31.99 × 0.25

7.9975

Add these all together:

10.995 + 9.6475 + 7.9975

28.64

Subtract this amount from the original cost of all the items:

(43.98 + 38.59 + 31.99) - 28.64

114.56 - 28.64

85.92

Solve for the sales tax:

85.92 × 0.0825

7.0884

Add the sales tax to the total:

85.92 + 7.0884

93.0084

Round up to the nearest cent:

93.01

93.01 < 100

Answer:

11 months

Step-by-step explanation:

Let x = months

y = total cost

Since Fitness 19 charges $30 a month, we multiply x by 30 like this: 30x

$44 is already added on the cost, so the Fitness 19 equation will look like this:

y = 30x + 44

Since LA Fitness charges $25 a month, multiply x by 25 like this: 25x

$99 is already added to the cost, so the LA Fitness equation will look like this:

y = 25x + 99

We need to find the point where they are both the same

30x + 44 = 25x + 99

First, move like terms to one side by subtracting 25x from both sides

30x + 44 = 25x + 99

- 25x         - 25x

5x + 44 = 99

Then, subtract 44 from both sides

5x + 44 = 99

     - 44 - 44

5x = 55

Finally, isolate the variable, x, by dividing both sides by the coefficient, 5

5x/5 = 55/5

x = 11

Part (a)

Answer: Point M could be at (9, -3) and could be at (-1, -3)

There are infinitely many answer choices

----------------------------------------------

Explanation:

We start at point L(4,-3). We could move 5 units to the right. Doing so means we add on 9 to the x coordinate to get 4+5 = 9. That moves us to (9,-3) which is one possible location for point M.

Now move back to point L(4,-3). Let's move 5 units to the left and we'll get to (-1,-3) which is another possible location for M. I subtracted 5 from the x coordinate of (4,-3).

There are infinitely many places M can be. It turns out that M can be anywhere on the circle of radius 5 and centered at (4,-3). The equation of this circle is (x-4)^2 + (y+3)^2 = 25.

===============================================================

Part (b)

Answer:  11 units

----------------------------------------------

Explanation:

Point L is at (4, -3)

Point K is at (-7, -3)

Both have -3 as the y coordinate. So we focus on the distance between the x coordinates.

To find that x coordinate distance, we subtract and use absolute value like so

|x1-x2| = |4 - (-7)| = |4 + 7| = |11| = 11

Order doesn't matter with subtraction that involves absolute value

|x2-x1| = |-7-4| = |-11| = 11

Either way, we see that the distance from K to L is 11 units. This is the same as the length of segment KL.

Answer:

  a. M1 = (0, 0), M2 = (4, 2)

  b. LK = |-7-4| = 11

Step-by-step explanation:

a. The infinite number of points that are 5 units from point M comprise a circle of radius 5 centered at M. There are 12 points on that circle that have integer coordinates.

Conveniently, 5 is the hypotenuse of a right triangle with sides 3 and 4. So, any point that has coordinate differences from L that are (±3, ±4) or (±4, ±3) will be 5 units away. (The signs can be chosen independently, so that's a total of 8 points.) Of course, points 5 units away on the same horizontal or vertical line will also be possible locations of point M: (4±5, -3) or (4, -3±5), a total of 4 more points.

The points we have shown in the attachment are (4, 2) and (0, 0).

__

b. The distance formula can tell you the length of LK:

  LK = √((-7-4)² +(-3-(-3))²) = √(-11)² = |-11| = 11

A length is always positive. The distance along a horizontal line can be found by subtracting one end-point x-coordinate from the other. In order to ensure the length is positive, the absolute value of the difference must be used.

In the case of the distance formula, we end up with √(d²) = |d|, where d is the difference of x-coordinates on the horizontal line.

Answer:

y = 700 + (1900/60)x

[or y = 700 + (95/3)x if you simplified]

Explanation:

Since the fixed cost is 700 dollars, any additional cost will be added to that.

Hence, 700 + in the equation.

The amount added to the 700 is (1900/60)x because per 60 items you spend $1900. So, for 1 item you spend (1900/60) [or (95/3) if you prefer to simplify as much as possible]. Thus, the cost of manufacturing multiple items is $(1900/60)x.

So, your final equation should read:

y = 700 + (1900/60)x

[or y = 700 + (95/3)x if you simplified]

Answer:

3/2, 1/2, - 1

Step-by-step explanation:

x + 2y = 1 --> this is 'f(x)'. Sub in the each x-value to the equations.

First part:

x = -2

x + 2y = 1

-2 + 2y = 1

2y = 3

y = 3/2

Second part:

x = 0

x + 2y = 1

0 + 2y = 1

2y = 1

y = 1/2

Third part:

x = 3

x + 2y = 1

3 + 2y = 1

2y = -2

y = -2/2

y = - 1

Total cost = $50 + $10(10)

Total cost = $50 + $100

Total cost = $150

The average cost per class :

Total cost / number of classes

$150 / 10
