Nico is saving money for his college education. he invests some money at 7%, and $1200 less than that amount at 3%. the investments produced a total of $174 interest in 1 yr. how much did he invest at each rate? he invested $ 7% and at 3%.

Nico invest at 7% and at 3%

Step-by-step explanation:

we know that

The simple interest formula is equal to

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

At 7%

substitute in the formula above

At 3%

substitute in the formula above

The total interest is equal to

I=I1+I2

I=$174

substitute

therefore

Nico invest at 7% and at 3%

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
