Answer:

N = 10

Step-by-step explanation:

Normally the coordinate system goes:

x axis (horizontal)

y axis (vertical)

Here, we have:

Horizontal axis as "M", and

Vertical axis as "N"

We want to know what N will be when M equals 50.

So, we look at the x-axis and go to M equals 50.

Then we move up until the "trend line". The intersection.

If we move directly left to vertical axis (N variable), we see that it is at the point:

N = 10

So,

When M = 50, N = 10

Z=Xm+n-p,solve for x
timama [110]

z=xm+n-p

We need to isolate x to one side I will do that on the left side so it looks cleaner, therefore I will first flip the equation.

xm+n-p=z

Now move the n and p to the right side

xm=z-n+p

x=(z-n+p)/m

Hope this helped, if you have any questions about this just comment and I will come answer.

An infinite geometric series has a first term ai = 15 and a sum of 45. Explain how you
oee [108]

Answer:

r= \frac{2}{3}

Step-by-step explanation:

The sum to infinity of a geometric series is calculated as

S∞ = \frac{a_{1} }{1-r} ; | r | < 1

where a₁ is the first term and r the common ratio

here a₁ = 15 and S∞ = 45 , then

45 = \frac{15}{1-r} ( multiply both sides by (1 - r ) )

45(1 - r) = 15 ( divide both sides by 45 )

1 - r = \frac{15}{45} = \frac{1}{3} ( subtract 1 from both sides )

- r = \frac{1}{3} - 1 = - \frac{2}{3} ( multiply both sides by - 1 )

r = \frac{2}{3}

2(4x - 1) + 3(3 - 2x) = 0
LUCKY_DIMON [66]
2(4x-1) + 3(3-2x)=0
distribute
8x-2+9-6x=0
add like terms
2x+7=0
subtract 7 from both sides
2x= -7
divide both sides by 2
x=-7/2
