Answer:

  40x +18(x -3) = 468

Step-by-step explanation:

If x is collected from each of 40 repeat customers, the amount collected from them is 40x.

If $3 less is collected from each of 18 new subscribers, the amount collected from them is 18(x -3).

The total amount collected is 468, so we have ...

  40x +18(x -3) = 468

Please help, i have no idea how to do this

Answer:

  8 square units

Step-by-step explanation:

The figure is a trapezoid. The area of it is given by the formula ...

  A = (1/2)(b1 +b2)h

where b1 and b2 are the lengths of the parallel bases and h is the distance between them.

Your figure shows the base lengths to be 5 and 3, and their separation to be 2. Filling the numbers in the formula, we have ...

  A = (1/2)(5 +3)(2) = (1/2)(8)(2) = 4·2 = 8

The area of the figure is 8 square units.

_____

The right-pointing arrows on the horizontal lines identify those lines as being parallel. The right-angle indicator and the 2 next to the dotted line indicate the perpendicular distance between the parallel lines is 2 units.

Marshall invest $4500 into an account bearing 6% interest compounded semiannually. How much interest will be added into this acc
Sphinxa [80]

Answer:

$1547.62

Step-by-step explanation:

The principal Marshall invested is $4500.

The rate of interest is 6%

The compound interest formula is

A=P(1+r)^n

We substitute P=4500,r=0.06 and t=5 to obtain:

A=4500(1+ \frac{0.06}{2} )^ {2 \times 5}

We simplify to get:

A=4500(1+ 0.03)^ {10} = 4500 \times  {1.03}^{10}

This gives us:

A=6047.62

The interest after 5 years is

6047.62 - 4500 = 1547.62

A equation for (7,2) and (2,12)
alexira [117]

Well to find this line you want to know the slope and the y-intercept. So find the slope:

(y2-y1)/(x2-x1)

12-2 = 10

2-7 = -5

10/-5 = 2/-1

-2 is your slope

Now for y-intercept, find the point closest to the y-axis. That is the point (2,12), and if your slope is negative 2, that means that if you go up 4 and left 2, you should find the y-intercept:

12 + 4 = 16

16 is your y-intercept

So now lets write this out in an equation:

y = mx + b

m = slope

b = y-intercept

y = -2x + 16

there you go! hope this helps!
