Answer:

(1,-3)

x=1 y= -3

Step-by-step explanation:

Looking at this we can see that there's a 2y in both of the equations (one is negative while the other is positive and so we'll add them)

so we have

(2x+2y)+(6x-2y)= -4+12

this simplifies to

8x=8

x=1

We know that x=1 and so we will plug this back into one of the two equations

2(1)+2y= -4

2+2y= -4

2y= -6

y= -3

Therefore the solution is (1,-3)

Answer:

2x+2y=-4

since we don't know the value of the letters, we could ignore it. then we add 2+2 which equals 4

6x-2y=12

In this case this equation is incorrect.

Step-by-step explanation:

sorry if I'm incorrect

(please if I'm correct, I really need the brainliest)

A dentist polls his patients and finds that 83 percent brush their teeth at least twice a day, 47 percent floss daily, and 19 pe

puteri [66]

Answer:

The correct option is B. 23%

Step-by-step explanation:

Let the event that patient brushes his teeth at least twice a day is denoted by A

So, P(A) = 0.83

Let the event that patient flosses daily is denoted by B

So, P(B) = 0.47

Now, it is given that 19 percent patients brush at least twice a day and floss daily.

⇒ P(A and B) = 0.19

Now, we need to find conditional probability of occurring event B given A has occurred.

$\implies P(B|A) =\frac{P(A\: and\: B)}{P(A)}\\\\\implies P(B|A) = \frac{0.19}{0.83}\\\\\implies P(B|A) = 0.2289\approx 0.23$

Hence, Nearest required percentage = 23%

Therefore, The correct option is B. 23%

State the type of angles and solve for the given variable.

Evgen [1.6K]

Step-by-step explanation:

the given pair is Alternate Exterior Angle

so their values are equal so,

→ 2x + 26 = 3x - 33

→ 2x - 3x = -33 - 26

→ x = 59

therefore option C is correct

hope this answer helps you dear...take care and may u have a great day ahead!

A farm increases in value from $800,000 to $1,100,000 over a period of 6 years. Use the formula r=(F/P)^1/n−1 to find the annual

enot [183]

Answer:

Step-by-step explanation:

The formula representing the the annual inflation rate r is expressed as

r = (F/P)1/n−1

Where

n represents the the number of years during which the value increases from P to F

A farm increases in value from $800,000 to $1,100,000 over a period of 6 years. This means that

P = $800,000

F = $1,100,000

n = 6

Therefore,

r = (1100000/800000)1/6−1

r = 1.375/5 = 0.275
