Rectangle Formula: a = lw (Area = Length x Width)

Trapezium: A= a+b/2h (Area = Area + Base / 2 x h)

I hope this helps. :)

Find the value of y when x equals 4.<br> -3x + 9y = -57

ANTONII [103]

Answer:

y = -5

Step-by-step explanation:

Isolate y:

-3x + 9y = -57

9y = -57 + 3x

y = (-57/9) + (3/9)x

Substitute for x:

y = (-57/9) + (3/9)(4)

y = (-57/9) + (12/9)

y = (-45/9)

y = -5

Answer:

Option D. $\$83.75$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=30\ years\\ P=\$187.45*0.10=\$18.745\\ r=0.05\\n=12$

substitute in the formula above

$A=\$18.745(1+\frac{0.05}{12})^{12*30}=\$83.75$
