For a solution to exist for two lines, y=y so we can say:

-3=7x-10 add 10 to both sides

7=7x divide both sides by 7

x=1

So the solution is the point (1, -3)

Find the value of the variable and YZ if Y is between X and Z. XY= 11, YZ=4c, XZ=83

svet-max [94.6K]

So you know the whole line is XZ which is 83.Then you find out it is in two parts so that is XY and YZ which are 11 and 4c. You can make the equation:

11+4c=83
4c=72
c=18

c=18 and YZ=72

Jen invested $3500 into a continuously compounded account with an interest rate of 3.1%. After 9 years, how much money is in the

GarryVolchara [31]

Answer:

≈$4607

Step-by-step explanation:

I will assume it's compounded yearly.

Apply the compound interest formula.

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

A = Total

P = Initial Principle

r = Interest Rate

n = number of interest in every t period

t = number of periods

In the case,

P = 3500

r = 3.1% = 0.031

n = 1

t = 9

Hence,

$A=3500(1+\frac{0.031}{1})^{1*9}$

$A = 4606.764717......$

A ≈ 4607 (nearest whole number)
