<span>y+4=3(x-7)
y + 4 = 3x - 21
y = 3x - 21 -4
y = 3x - 25

when x = 7
y = 3(7) - 25
y = -4
Therefore (7, -4) pass through this equation </span>

Ian and April wish to have 8,000 available for the wedding in six years how much money should be set aside now at 6% compounded
ira [324]

Answer:

\$5,586.42  

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=6\ years\\ A=\$8,000\\ r=0.06\\n=12  

substitute in the formula above  

8,000=P(1+\frac{0.06}{12})^{12*6}  

8,000=P(1.005)^{72}  

P=8,000/(1.005)^{72}  

P=\$5,586.42

Algebraically determine the x-intercepts of this function. Please show work.
WINSTONCH [101]
To determine x intercept, put y=0

<span>x^4 - 10x^2 + 9  = 0
</span>
<span>x^4 - 9x^2  - x^2 + 9 = 0

x^2(x^2 - 9) - 1(</span><span>x^2 - 9) = 0

(</span><span>x^2 - 9)(x^2-1) =0

x^2 - 9 = 0
⇒ x^2 = 9
⇒x = +3, -3

x^2 - 1 = 0
x^2 = 1
x = +1, -1

X intercepts are -3, -1, 1, 3
