​ y=3x+3 y=−2x+3 ​ how many solutions does the system have

Answers

Answer: One solution

Step-by-step explanation:

y = 3x + 3

y = -2x + 3

-----------------------------------------------------------------------------------------------------------

To solve this, you need to understand a few things:

a) If two lines have the same slope but different y-intercepts, they are parallel when graphed and thus do not have any solutions

b) If two lines have the same slope and same y-intercepts, they are the same line when graphed and thus do not have infinitely many solutions

c) If two lines have different slopes (and/or y-intercepts), they have one solution

-----------------------------------------------------------------------------------------------------------

These two lines have different slopes but the same y-intercept (condition c)

So they have one solution

the annual rent of the house is 3600$ . Find the rent of 5 months

Answers

Answer:

1500 dollars

Step-by-step explanation:

annual means yearly and we want to find how much it will cost for 5 months

First thing we want to do is find how much it cost every month and to do that we divide 3600 by 12

3600/12=12 so it cost 300 dollars monthly

then we just multiply that by 5

5x300=1500 so it cost 1500 dollars for 5 months

Construct a probability distribution for the data.
7. The probabilities that a patient will have blood drawn 0,1,2, or 3 times in a visit are 6/15, 5/15, 3/15, and 1/15, respectively.

Answers

Answer:

X : ___ 0 ____ 1 _____ 2 ______ 3

P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15

Step-by-step explanation:

From the data, to produce a probability distribution for the data :

X : number of times blood is drawn ;

P(x) : probability that blood is drawn at X times

Hence, the probability distribution table for the data Given goes thus :

X : ___ 0 ____ 1 _____ 2 ______ 3

P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15

Probability that blood is drawn 0 times = 6/15

Probability that blood is drawn 1 time = 5/15

Probability that blood is drawn 2 times = 3/15

Probability that blood is drawn 3 times = 1/15

(6/15 + 5/15 + 3/15 + 1/15) = 1

What is the degree measure of Angle P?

Answers

Answer:

D. 40°

Step-by-step explanation:

Angle formed by two secants is half of the difference of intercepted arcs:

m∠P = 1/2(mST - mQR)

Find the measure of missing arc:

mQR = 360° - (85° + 95° + 175°) = 5°

Substitute the value of arc QR into above equation:

m∠P = 1/2(85° - 5°) = 40°

two numbers have ratio 12:5.their differnce is 49.find the two numbers .​

Answers

Answer:

84 and 35

Step-by-step explanation:

12 - 5 = 7

12(7) = 84

5(7) = 35

Two numbers: 84 and 35

Step-by-step explanation:

Let the two numbers be x and y

Given:

Ratio of two numbers= 12:5

Difference between two numbers= 49

So, we need to find the difference between its ratio in order to get two numbers.

12 - 5 = 7

Thus, simply on multiplying the number so obtained after subtraction we will get:  

12 * (7) = 84

5 * (7) = 35

Also, the difference is given which is 49

so, we can confirm it by finding the difference between the numbers obtained which is 84-35=49

Therefore, the two numbers are 84 and 35.

You pay 3.5% annual simple interest for 12 years on a loan, and you pay $1,512 in interest. How much is the principal?

Answers

A = Pe^rt
Amount of interest paid = Principal*e^ (rate*time)
(The rate must be in decimal form)
3.15% / 100 = .0315

1,512 = P[e^(.0315*12)]
1,512 / e^(.0315*12) = P
