Answer:

2. ΔABC is isosceles

Step-by-step explanation:

Given : m∠A = 50

m∠BCD = 180 - (m∠BDC + m∠DBC)

              = 180 - (100 + 30)

              = 50

then

m∠A = m∠BCD

therefore ΔABC is isosceles

Given an investment of $2300, after 7 months, earning 6.6% APR, compounded monthly, the future value is given by
AVprozaik [17]

we are given

investment amount is 2300

so,

P=2300

r=6.6%

r=0.066

it is compounded monthly

so,

n=12

now, we can use formula

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

now, we can plug values

t=7/12

and we get

FV=2300(1+\frac{0.066}{12})^{7}

now, we can find FV

FV= $2390.02454............Answer

Which is the solution of the following system of equations: 2x + y = 4 3x – y = - 14
murzikaleks [220]

2x + y = 4 \\ 3x - y =  - 14

Lets add 2 equations

5x =  - 10 \\ x =  - 2

Now we need to put x into any equation

2 \times ( - 2) + y = 4 \\  - 4 + y = 4 \\ y = 8

Answer: (-2; 8)
