Which of the graphs below correctly solves for x in the equation −x2 − 3x − 1 = −x − 4?
gtnhenbr [62]

Answer:

Graph of quadratic opening downward and linear sloping up to the left. They intersect at point negative 3, negative 1 and point 1, negative 5

Step-by-step explanation:

we have

-x^{2} -3x-1=-x-4

we can separate the expression above into two equations

y=-x^{2} -3x-1 ----> equation A

This is a quadratic equation ( vertical parabola) open downward (the leading coefficient is negative)

y=-x-4 ----> equation B  

This is a linear equation with negative slope (decreasing function).so linear sloping up to the left

The solution of the original expression are the x-coordinates of the intersection point both graphs

using a graphing tool

The intersection points are (-3,-1) and (1,-5)

see the attached figure

Lindsay invested $4500 at 4% interest compounded annually.
goldfiish [28.3K]

Answer:

\$2,161.1

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=10\ years\\P=\$4,500\\ r=0.04\\n=1  

substitute in the formula above  

A=\$4,500(1+\frac{0.04}{1})^{1*10}  

A=\$4,500(1.04)^{10}

A=\$6,661.10    

Find the interest

I=A-P

I=\$6,661.10-\$4,500=\$2,161.1
