Hey there!

First, we would determine what the first x-axis and y-axis have in difference. We would analyze the following:

<u>For number 1:</u> 55-90= 35 ... 90+35 = 125 ... 125+35=160.

The key number here would be 35.

Therefore, the equation would be the following:

the \ next \ equation\left \{ {{y=195+35=\bf(230)} \atop {6=2}} \right.

Answer: y=35x+20

The answer is y = 35x + 20.

In order to find this, start with two ordered pairs. For the purpose of this problem, we'll use (1, 55) and (2, 90). Now we use the slope formula to find the value next to x in the equation.

m(slope) = (y2 - y1)/(x2-x1)

In this equation (x1, y1) is the first ordered pair and (x2, y2) is the second. Plug in to the equation and solve.

m = (90 - 55)/(2 - 1)

m = 35/1

m = 35

Now that we have the slope, plug that into the equation along with either point to find the intercept (the last number).

y = mx + b

55 = 35(1) + b

55 = 35 + b

20 = b

Now that we have the slope and intercept, we can use each to fill in those blanks.

y = 35x + 20

Consider a circle centered at C(-2,-4). If the point P(1,-1) lies on the circle, then which of the following points also lies on
Aliun [14]

Answer:

Consider a circle centered at C(-2,-4). If the point P(1,-1) lies on the circle, then which of the following points also lies on the circle?

<h3>A. (-2, -√18)</h3>

B. (-2+√18, -4)

C. (√18, -4)

D. (-2, 4+√18)

Step-by-step explanation:

  • If the distance is greater than the radius, the point lies outside. If it's equal to the radius, the point lies on the circle. And if it's less than the radius, you guessed it right, the point will lie inside the circle.

hope it's help you

12x15y=4140; x+y= ? <br> solve.
Semenov [28]

Answer: The number of $12 tickets and $15 sold are 120 and 180 respectively.

Step-by-step explanation:

The given equation is:

12x + 15y = 4140             .....(1)

Where,

x stands for $12 tickets and y stands for $15 tickets

According to the question:

x + y = 300           ....(2)

Now solving equation 1 and 2.

From equation 2:

x = 300 - y

Now putting this expression in equation 1.

12x + 15y = 4140

12(300 - y) + 15y = 4140

3600 - 12y + 15y = 4140

3600 + 3y = 4140

3y = 4140 - 3600

3y = 540

y = 180

And,

x = 300 - y = 300 - 180 = 120

The number of $12 tickets sold = x = 120

The number of $15 tickets sold = y = 180

Thus, the number of $12 tickets and $15 sold are 120 and 180 respectively.
