Algebraically find the x-coordinates where the line y=2x+3 intersects the circle (x-3)^2 + (y+6)= 50

Answers

Answer 1

The x-coordinates where the line y = 2x + 3 intersects the circle is equal to -2 and -4.

What is the equation of a circle?

Mathematically, the standard form of the equation of a circle is represented by this mathematical expression;

(x - h)² + (y - k)² = r²  

Where:

h and k represents the coordinates at the center of a circle.r represents the radius of a circle.

From the information provided, we have the following system of equations:

(x - 3)² + (y + 6)² = 50      ......equation 1.

y = 2x + 3              .............equation 2.

In order to determine the x-coordinates at the point of intersection, we would substitute the equation 2 into equation 1:

(x - 3)² + (2x + 3 + 6)² = 50

(x - 3)² + (2x + 9)² = 50

x² - 6x + 9 + 4x² + 36x + 81 - 50 = 0

5x² + 30x + 40 = 0

x² + 6x + 8 = 0

x² + 6x + 9 = 1

(x + 3)² = 1

Taking the square of both sides of the equation, we have;

x + 3 = ±1

x = ±1 - 3

x = -2 and -4

Find the least common multiple (LCM) for the pair of numbers 6 and 18 ​

Answers

Answer:

the lcm is 6

Step-by-step explanation:

6 divided by 3 is 1

18 divided by 3 is 6

6 becomes 3 and 2

Answer:

18

Step-by-step explanation:

Since the question is asking for the least common multiple, you factor out the 6 in 18 and 6. This gives you 631 as the LCM because you have factored out 6 and this is the GCF because there are no more common factors between 3 and 1. Since 631 equals 18, 18 is the LCM

Answer:

Step-by-step explanation:

The n-th term of the geometric series is ...

  an = a1(r^(n-1))

for first term a1 and common ratio r. The common ratio here is the growth factor: 1 -20% = 0.8. This means the 5th term (5th year sales) will be ...

  a5 = 600(0.8^(5-1)) ≈ 246 . . . . . products sold in year 5

The sum is given by ...

  sn = a1(1 -r^n)/(1 -r) = 600(1 -0.8^5)/(1-0.8) = 2017

The company will have sold about 2017 products over 5 years.

to empty the aquarium?

Answers

9514 1404 393

Answer:

  20 minutes

Step-by-step explanation:

The volume is given by ...

  V = LWH

  V = (40 in)(22 in)(16 in) = 14,080 in³

If water is removed at the rate of 704 in³/minute, the time to remove it all is ...

  t = quantity/rate = (14,080 in³)/(704 in³/min) = 20 min

It takes 20 minutes to empty the aquarium.

The sum of two numbers is 9. If one number is subtracted from the​ other, the difference is −3. Find the two numbers.

Answers

Answer:

The numbers are 6 and 3

Step-by-step explanation:

Let the numbers be x and y

So their sum is x + y =9 (EQ. 1)

Their difference is x - y = -3 (EQ. 2)

Solve simultaneously using subtract method.

x-x=0, x is eliminated. y- -y = +2y since -x- is +.

so it is now 2y = 9- - 3:. 2y= 12; dividing both sides by 2. Y=6.

Substitute Y=6 in EQ 1 to find x.

So x + 6=9;. x=9-6 is achieved by collecting like terms. so x=3.

:. Y=6 and x=3. The numbers are 6 and 3

Answers

Answer:

Mode

Step-by-step explanation:

because 90 is the grade that shows up the most!

I hope I helped :)

Measure of center that Erica should use is mode to get the highest average on her scores.

What is Mean, Median and Mode?

For a set of data, mean is the average of all the elements in the data set.

Median is the element in the exact middle when numbers are arranged from smallest to largest or largest to smallest.

Mode is the element which is most repeated.

The given data set is,

80, 90, 70, 60, 90

Mean = (80 + 90 + 70 + 60 + 90) / 5 = 78

To find median, firstly arrange the numbers in order.

60, 70, 80, 90, 90

The middle element is the element in the third place, 80 which is the median.

90 is the only element which appears more than once. So mode is 90.

Mode gives the highest score.

Hence Erica should use mode as the measure of center to get the highest average.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that the equation as;
