Answer:

C. Graph the first equation, which has slope = −2 and y-intercept = 3, graph the second equation, which has slope = −4 and y-intercept = −1, and find the point of intersection of the two lines.

Step-by-step explanation:

The two equations are in slope intercept form which is y = mx + b where m is the slope and b is the y-intercept.

In the first equation (y = -2x + 3), -2 is the slope since it is the coefficient. "b" is 3 since it is the constant of the equation.

In the second equation (y = -4x -1), -4 is the slope is the coefficient, and the y-intercept is -1 since it is the constant.

To solve the equations graphically, graph them and find the point where they intersect.

What is the value of x?

satela [25.4K]

Answer:

x = 4

Step-by-step explanation:

By property of intersecting secants outside of circle.

$PC \times PA = PB \times PD \\ 10(2x + 10) = 9(2x + 3 + 9) \\ 20x + 100 = 18x + 108 \\ 20x - 18x = 108 - 100 \\ 2x = 8 \\ x = \frac{8}{2} \\ \huge \red{ \boxed{ x = 4}}$

six people, including A,B, and C, form a queue in a random order (all 6! orderings are equiprobable). Consider the event "B is b

mojhsa [17]

Answer:

There is a 1.39% probability that "B is between A and C in the queue".

Step-by-step explanation:

The first step to solve this problem is find the total number of possible orderings:

The first person of the queue can be any of the six. The second, can be any but the first, so five.

There are 6*5*4*3*2*1 = 720 total queue orderings.

Now we find the number of queues that B is between A and C. So:

We have:

B as the second, A as the first and C as the third

B as the second, C as the first and A as the third

B as the third, A as the second and C as the fourth

B as the third, C as the second and A as the fourth

B as the fourth, A as the third and C as the fifth.

B as the fourth, C as the third and A as the fifth.

B as the fifth, A as the fourth and C as the sixth.

B as the fifth, C as the fourth and A as the sixth.

So 8 total outcomes in which B is between A and C.

What is its probability?

$P = \frac{8}{720} = 0.0111$

There is a 1.11% probability that "B is between A and C in the queue".

To find the correct order of similarity we see and compare the sides of both the trapeziums

LM corresponds to QR

KL to PQ

NM to SR

So the correct order should be

The area of rhombus is 360cmsquare and one of its diagonalis 18cm. Find the other diagonal.

Yanka [14]

Answer: 40 cm

So the diagonal formula is - 1/2* (d1*d2) d1 is the first diagonal and d2 is the second diagonal.

So,

1/2 * (18*d2)= 360

18*d2= 360*2

d2= 720/18

d2= 40
