A direct variation function contains the points (–9, –3) and (–12, –4). Which equation represents the function?

Natasha_Volkova [10]

First, find the slope between the two points.
Slope = y2-y1 / x2-x1
-4+3/ -12+9
-1/-3
1/3 is the slope of this equation.
You do not have to go any further to find b or the y-intercept because it appears that b or the y-intercept is 0 in this case.
y= 1/3x or in other words y= x/3

To convert mixed fractions to improper fractions:

a b/c=(ac+b)/c so we have:

43/10+127/30+37/15 now making all terms have a common denominator of 30

(43/10)(3/3)+(127/30)(1/1)+(37/15)(2/2)

129/30+127/30+74/30

(129+127+74)/30

RS 3560 becomes RS 4272 in 8 years at S.I. What will be the simple interest on Rs 6480 in 14 years at the same rate of interest?

Readme [11.4K]

Answer:

$RS\ 8,748$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

step 1

Find the rate of interest

in this problem we have

$t=8\ years\\ P=RS\ 3,560\\ A=RS\ 4,272\\r=?$

substitute in the formula above

$4,272=3,560(1+8r)$

solve for r

$8r=(4,272/3,560)-1$

$r=[(4,272/3,560)-1]/8$

$r=0.025$

convert to percentage

$r=0.025*100=2.5\%$

step 2

What will be the simple interest on Rs 6480 in 14 years at the same rate of interest?

we have

$t=14\ years\\ P=RS\ 6,480\\ A=?\\r=0.025$

substitute in the formula above

$A=6,480(1+0.025*14)$

$A=6,480(1+0.35)$

$A=RS\ 8,748$
