Answer:

x intercept=(2,0)

y intercept=(0,6)

Step-by-step explanation:

when finding the x intercept you multiply the y by zero so you are just left with the x. then you would divide six and 3x by 3 so that you just get x, and you would get that x=2.

You do the same for the y intercept except you multiply x by xero, so you would be left with y=6.

What is the answer to 3(x+1) = 5+x

AleksandrR [38]

3 (x + 1) = 5 + x

First you must distribute the 3 to the values inside the parentheses:

3 (x + 1) = 5 + x

(3 * x) + (3 * 1) = 5 + x

3x + 3 = 5 + x

Now you must combine like terms. Like terms are numbers that have matching variables like 3x and x OR are numbers with out variables like 3 and 5.

3x - x = 5 - 3

2x = 2

Next, to completely isolate x, divide 2 to both sides. Since 2 is being multiplied by x, division (the opposite of multiplication) will cancel 2 out (in this case it will make 2 one) from the left side and bring it over to the right side.

2x / 2 = 2 / 2

1x = 1

Check:

3 (1 + 1) = 5 + 1

3 (2) = 5 + 1

6 = 6

^^^This is true, therefore:

x = 1

The following data represent the number of people aged 25 to 64 years covered by health insurance (private or government) in 2

Yuri [45]

The mean age is equal to: 44.09.

The standard deviation is equal to: 10.07.

<h3>How to determine the mean age and standard deviation?</h3>

First of all, we would determine the median of each class interval as follows:

Median 1 = (25 + 34)/2 = 29.5

Median 2 = (35 + 44)/2 = 39.5

Median 1 = (45 + 54)/2 = 49.5

Median 1 = (55 + 64)/2 = 59.5

Next, we would calculate the mean age by using this mathematical expression:

Mean age = ∑fx/∑f

Substituting the given parameters into the formula, we have;

Mean age = [(24.3 × 29.5) + (36.1 × 39.5) + (36.7 × 49.5) + (20.9 × 59.5)]/(24.3 + 36.1 + 36.7 + 20.9)

Mean age = [716.85 + 1,425.95 + 1,816.65 + 1,243.55]/118

Mean age = [5,203]/118

Mean age = 44.09.

Now, we can calculate the standard deviation as follows:

Standard deviation, S = √((∑f(xi - μ)²/∑f)

Standard deviation, S = √((24.3 × (29.5 - 44.09)² + (36.1 × (39.5 - 44.09)² + (36.7 × (49.5 - 44.09)² + (20.9 × (59.5 - 44.09)²)/(24.3 + 36.1 + 36.7 + 20.9))

Standard deviation, S = √((5172.70 + 760.56 + 1,074.14 + 4,963.08)/118)

Standard deviation, S = √(11,970.48/118)

Standard deviation, S = √101.5

Standard deviation, S = 10.07.

Figure ABCDE was reflected across the line y = x to

Anon25 [30]

Answer: E is located at (-2, 6)

Explanation:

The rule for reflecting over y = x is $(x,y) \to (y,x)$

The x and y coordinates swap places.

Point E' is located at (6, -2) so that means point E must be located at (-2, 6)
