I don't know what you are looking for
but the equation y = 1/2 x + 7 is called slope intercept form, one of the easiest way to draw line/linear graph.
It has slope(m) of 1/2 and y-intercept (b) of 7.

y= mx + b

18,000 amounts to 21,600 in 4 years at simple interest. Find the sum of

AnnyKZ [126]

Answer:

$\$20,400$

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

$t=4\ years\\ P=\$18,000\\ A=\$21,600\\r=?$

substitute in the formula above and solve for r

$\$21,600=\$18,000(1+4r)$

$1.2=(1+4r)$

$4r=1.2-1$

$r=0.2/4=0.05$

The rate of interest is $5\%$

step 2

Find the sum of money that will amount to 25,500 in 5 years, at the same rate of interest

in this part we have

$t=5\ years\\ P=?\\ A=\$25,500\\r=0.05$

substitute in the formula above and solve for P

$\$25,500=P(1+0.05*5)$

$P=\$25,500/(1.25)=\$20,400$

Y - 5 = -2x - 4 Write in simpilest form.

Romashka-Z-Leto [24]

Y - 5 = -2x - 4

Add 5 on both sides.
y = -2x + 1

y = -2x + 1 is in simplest form.

Jill’s room is 12 feet long and 10 feet wide. she made a scale drawing of the room with a scale of 0.5 inches = 2 feet. what is

umka21 [38]

12/2=6.
6X0.5=3
so the scale drawing is 3 inches long
10/2=5
5X0.5=2.5
so the width of the scale drawing is 2.5 inches
3+3+2.5+2.5=11
