We are given

First equation:

y=x-1

we can use formula

y=mx+b

slope is m=1

y-intercept is b=-1

Second equation:

y=-2x+5

we can use formula

y=mx+b

slope is m=-2

y-intercept is b=5

Graph:

We can see that

both curves intersect at (2,1)

so, solution is x=2 and y=1.................Answer

X/3/4 = 100<br> what does x equal
Crank

Answer:

x=1200

Step-by-step explanation:

x/3/4=100

Step 1: Multiply both sides by 4.

x/3/4=100

(x/3/4)*(4)=(100)*(4)

x/3=400

Step 2: Multiply both sides by 3.

3*(3/x)=(3)*(400)

x=1200

Which infinite geometric series can you NOT find the sum?
Oksanka [162]

Answer: C) 127, 152.4, 182.88, 219.456,...

Step-by-step explanation:

You can only find the sum of an infinite geometric sequence if it converges.

One criterion to see if the series converges is if:

aₙ < aₙ₋₁

This means that, as n increases, the value of the terms decreases.

This means that as n tends to infinity, aₙ tends to zero.

Then we only can find the sum of those series where the terms are decreasing.

in A, B and D the terms are decreasing, then we can find the sum of those 3 series.

Now in the case of C, the terms are increasing, then we can not find the sum of that series.

if serena invested the 2500 in the cd that she yields at 4% interest, what will the cdbe worthafte 2 years?
Naya [18.7K]

Your answer would be <u>2700</u>

Using I=P*r*t

P= 2500

R= 4% (substitue to 0.04)

T= 2 Years

I= 2500* 0.04 * 2

I= 100* 2

I= 200

2500+200=

2700
