Answer 2

Using the concept of combination, the value of the expression 9C4 is 126

Recall the combination formula :

[tex]nCr = \frac{n!} {(n-r)!r!} [/tex]

[tex]9C4 = \frac{9!} {(9-4)!4!} [/tex]

[tex]9C4 = \frac{9 \times 8 \times 7 \times 6} {4 \times 3 \times 2 \times 1} [/tex]

[tex]9C4 = \frac{3024} {24} = 126 [/tex]

Therefore, the value of the expression 9C4 is 126.

What is 2 (x-3) -(6x-4)

Answers

Answer:

simplify = - 4 x -2  factored = 2 (-2x - 1)

Step-by-step explanation:

Write the equation in slope-intercept form, identify the slope and the y-intercept.

(Slope-intercept form: y = mx + b)

-2x + 3y = -6

Answers

Answer:

Slope is 2; y-intercept is (0,-6)

Step-by-step explanation:

Slope intercept form looks like 3y = 2x - 6

In the equation y=mx+b, M is always the slope, and B is always the y-intercept. Therefore if you look back at the problem the slope number should be in front of the x which makes it 2. Since the y-intercept is always b, y = -6.

Slope or m = 2; y-intercept is (0,-6)

Answer:

y = [tex]\frac{2}{3}[/tex] x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- 2x + 3y = - 6 ( add 2x to both sides )

3y = 2x - 6 ( divide all terms by 3 )

y = [tex]\frac{2}{3}[/tex] x - 2 ← in slope- intercept form

with slope m = [tex]\frac{2}{3}[/tex] and y- intercept c = - 2

The table shows the temperature (y) at different altitudes (x).
This is a linear relationship. (Example 2)
2)Find the slope of this relationship

3)Find the y-intercept for this relationship

4)Write an equation in slop intercept form that represents this relationship

5)Use the equation to determine the temperature at an altitude of 5000 feet

Answers

Answer/Step-by-step explanation:

2. Using two pairs of values, (0, 59) and (2,000, 51),

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{51 - 59}{2,000 - 0} = \frac{-8}{2,000} = -\frac{1}{250} [/tex]

3. The y-intercept is the value of y when x = 0. Thus, x = 0, when y = 59. Therefore,

y-intercept (b) = 59

4. To write an equation in slope-intercept form, simply substitute m = -¹/250, and b = 59, in [tex] y = mx + b [/tex]

✅[tex] y = -\frac{1}{250}x + 59 [/tex]

5. Substitute x = 5,000 in [tex] y = -\frac{1}{250}x + 59 [/tex].

[tex] y = -\frac{1}{250}(5,000) + 59 [/tex]

[tex] y = -20 + 59 [/tex]

[tex] y = 39 [/tex]

At an altitude of 5,000 ft, temperature would be 39°F

Answers

Km = miles x 1.609

240 x 1.609 = 386.24 km

The answer is D. 386 kilometers

Answer:

D. 386

Step-by-step explanation:

If we know that we have 240 miles then we need to find the Km/m which is 1.60934 Km to 1 M, and we have the equation y= 1.60934(x), y bing the total amount of Km, or in other words, your answers, and x is the miles. Now change that x into 240 so now you have y= 1.60934(240) which comes out to 386.2416 Km or 386Km as seeing you have to round tho the nearest whole number.

An architect designs two similar triangular patios. The first patio has angle measures of (x + 10)°, (y + 15)°, and 70°. The second patio has angle measures of (x + 20)°, 50°, and 60°. Find the values of x and y.

Answers

Answer:

x is 50

y is 55

Step-by-step explanation:

Let us start working with the second patio

At any point in time, the total measure of the angles of a triangle is 180

Thus in the second patio;

x + 20 + 50 + 60 = 180

x + 130 = 180

x = 180-130

x = 50

In the first patio;

x + 10 + y + 15 + 70 = 180

substitute 50 for x

50 + 10 + y + 65 = 180

60 + 65 + y = 180

y = 180-60-65

y = 55

Answer:

the other answer above is wrong,

x=50

y=35

z = 3[tex]\sqrt{13}[/tex]

Step-by-step explanation:

Using the altitude- on- hypotenuse theorem

( leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )

z² = 9 × (9 + 4) = 9 × 13 = 117 ( take square root of both sides )

z = [tex]\sqrt{117}[/tex]

  = [tex]\sqrt{9(13)}[/tex]

Gerry arrived at the bus stop x hours past noon. Dale arrived 4 hours later. Pat arrived at 5 P.M., x hours after Dale.

At what time did Gerry arrive at the bus stop? [Your answer must include an A.M. or a P.M.]

Answers

Answer:

Gerry arrived at the bus station at 12:30 P.M.

Step-by-step explanation:

From noon and 5:00 P.M. there are 5 hours.

Gerry, Dale, and Pat arrived at the bus stop within that interval, which means the sum of the times elapsed between their arrival times must be 5.

4 out of the 5 hours elapsed since Gerry and Dale's arrivals. This means there is only one hour left for twice x.

If twice x is one hour, then x is half an hour. Thus, the complete sequence of arrivals is:

Gerry arrived at the bus station at 12:30 P.M.

Dale arrived at the bus station at 4:30 P.M.

Pat arrived at the bus station at 5:00 P.M.

my and Stephanie were playing a number game. Amy picked a number and told Stephanie that if she added 8 to the number and multiplied the sum by 3, it would equal 9. Which equation could Stephanie use to find the number, x?
A.
3 + (x + 8) = 9

B.
8(x + 3) = 9

C.
3(x + 8) = 9

D.
3(x) + 8 = 9

Answers

C.
3(x+8)=9
Always make sure u do PEMDAS so since the number that Amy picked is unknown we will label it X. Next step was x added to 8 which will look like this x+8 but wants the sum multiplied by 3 so since we don't know the answer we will close it in parenthesis and multiply it by 3 which will look like 3(x+8) and lastly add the equal sign and the number 9.
