8C2  * 6C2

============

14C4

8C2 = 8*7/1 * 2 = 28

6C2 = 6*5 / 1*2 = 15

14C4 = 14*13 *12 * 11 / (1 * 2 * 3 * 4) = 1001

28 * 15 / 1001 = .4195

Answer:

y = x - 1

Step-by-step explanation:

If it's parallel to x - y = 7, that means the slope of that equation is the slope for the equation you're looking for.  

To get the slope, you need to put the given equation into slope intercept form, so move x to the other side. You should get: -y = 7 - x

Then, to get the y positive, divide by -1:     y = -7 + x

Slope intercept form is as follows: y = mx + b, so whatever the number is in front of x is your slope. In this instance, your slope is 1.

You now have your slope, and a point in which your new line passed through. Using slope intercept form, y = mx + b, if you substitute in what you know, you can find your answer. Right now you know y, m, and x, and you're looking for b.  

x=1; y=0; m=1.  

So, substituting, you'd get 0 = (1)(1) + b

0=1+b     Solve

You should get b= -1, leaving your final answer as y = x - 1

y=x+1 is the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7.

The slope will be same as it is parallel.

x - y = 7.

-y=7-x

y=x-7

Slope is 1.

Now equation of line passing through (1,0)

0=1(1)+c

c=-1

y=x-(-1)

y=x+1

Hence y=x+1 is the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7.

Answer:

I'm pretty sure it's 16

Step-by-step explanation:

it measures up with the other triangles side

Answer:

Perimeter = 15

Step-by-step explanation:

We are told that the length of each of the 3 sides of the triangle are consecutive odd integers.

Thus means that we can write the 3 terms as;

(x - 2), x, (x + 2)

Thus, perimeter is;

P = (x - 2) + x + (x + 2)

P = 3x

If an angle is 120°, it means that the corresponding side that is directly opposite the angle is the largest side of the triangle.

Thus, this side is (x + 2)

Using cosine rule, we have;

(x + 2)² = x² + (x - 2)² - 2(x(x - 2))cos 120

Expanding, we have;

x² + 4x + 4 = x² + x² - 4x + 4 - (2x² + 4x)(-½)

This reduces to;

4x = x² - 4x + x² - 2x

2x² = 10x

2x = 10

x = 10/2

x = 5

Thus, other sides are;

(x - 2) = 5 - 2 = 3

And (x + 2) = 5 + 2 = 7

So,perimeter is;

P = 3x = 3 × 5 = 15

2a^2 b^3(3a^2 b^3 - 4ab^2 + 6)

Answer:

1, 3

Step-by-step explanation:

1. x > x

Technically, one number cannot be more than itself. It can only equal to itself.

3. –4 + x > –2 + x

If you minus x from both sides of the equation, it becomes:

-4 > -2

This is not true no matter what x is, thus it has no solution.

4. x – 2 < x + 3

If you add 2 on both sides, it becomes:

x < x + 5

This inequality is possible and has infinitely many solutions.

Note: I will update this answer and address Question 2 once the inequality sign is given :)

Answer:

4. The solution to the system of equations is: (2,-1)

5. The solution to the system of equations is: (3,5)

Step-by-step explanation:

4. What is the solution to the system of equations?

[tex]2x+3y=1\\-3x+4y=-10[/tex]

Let:

[tex]2x+3y=1--eq(1)\\-3x+4y=-10--eq(2)[/tex]

Multiply eq(1) by 3 and eq(2) by 2 and add both equations

[tex]6x+9y=3\\-6x+8y=-20\\---------\\0x+17y=-17\\y=\frac{-17}{17}\\y=-1[/tex]

So, value of y=-1

Now finding the value of x bu putting value of y in eq(1)

[tex]2x+3y=1\\2x+3(-1)=1\\2x=1+3\\2x=4\\x=\frac{4}{2}\\x=2[/tex]

So, value of x=2

The solution to the system of equations is: (2,-1)

5. What is the solution to the system of equations?

[tex]y=2x-1\\6x-y=13[/tex]

Let:

[tex]-2x+y=-1--eq(1)\\6x-y=13--eq(2)\\------\\4x=12\\x=\frac{12}{4}\\x=3[/tex]

So, value of x=3

Putting value of x in equation 1 to find value of y

[tex]y=2x-1\\y=2(3)-1\\y=6-1\\y=5[/tex]

So, value of y=5

The solution to the system of equations is: (3,5)

Answer:

1

Step-by-step explanation:

61.26 rounded to the nearest whole number = 61

59.593 rounded to the nearest whole number = 60

61 - 60 = x

61 - 60 = 1

x = 1

Answer:

Step-by-step explanation:

Since we are not given the dimension. Let us say the shape of the patio is a rectangle with length 30m and width 18m.

Area of the rectangle = Length * Width

Area of the rectangle = 30 * 18

Area of the rectangle = 540m²

This means that 540m² of the patio costs $2276.35. To get the cost of each square metre of patio, we will say;

540m² = $2276.35

1m² = x

cross multiply;

540x = $2276.35

x = $2276.35/540

x = $4.22

Hence each square meter of patio will cost $4.22

Note that the dimension of patio was assumed. Same explanation can be employed for any dimension.
