Answer:


Step-by-step explanation: so to find slope it’s y2-y1/x2-x1

Slope is 1/6

Y = 1/6x + b

Plug in one set of points to find b Idek if u need to find it but

2 = 1/6(12) + b

2 = 6  + b

2-6 = -4

Y = 1/6x -4

What is the total amount in an investment of $3500 that was compounded quarterly for 8 years at a rate of 5%?
erica [24]

Answer:

Principal = 3500

Time = 8 years

We are given that compound quarterly

So, No. of compounds per year = 2

Rate of interest = 5%

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

Substitute the values :

A=3500(1+\frac{0.05}{2})^{2 \times 2}

A=3863.345

Interest = 3863.345 - 3500 = 363.345

Hence the total amount in an investment of $3500 that was compounded quarterly for 8 years at a rate of 5% is $3863.345 and the interest that was made on that account mentioned is $363.345

y = x2 − 6x 8 2y x = 4 the pair of points representing the solution set of this system of equations is___ and ___?
mariarad [96]
Some operators are missing.
If the right equations are y = x^2 -6x +8 and 2y + x =4
This is the solution

2y + x = 4
2y = -x +4
y = -x/2 + 2

y = x^2 -6x + 8 = -x/2 + 2

2x^2 - 12x + 16 = -x + 4
2x^2 -11x +12 = 0

Factor

(x-4)(2x-3)=0

x= 4 and x =3/2

y = -x/2 +2
 
y = -4/2 + 2 = 0
y = - (3/2)/2 + 2 = -3/4 + 2 = 5/4

Answer (4,0) and (3/2, 5/4)
