Answer:

y = 2x + 2

Step-by-step explanation:

given       : line passes through the points (4,10) and (9,20)

Required :  write a linear function in terms of x and y

solution   :

substitute the coordinate points into the equation: y = mx + b

(x=9, y=20)      _   20 = 9m + b

(x=4, y=10)           <u>  10 = 4m + b  </u>

subtracting           10 = 5m

                               m = 10/5

                               m = 2

substitute x=2 back into eq.1 to solve for b

20 = 9m + b

20 = 9(2) + b

20 - 18 = b

b = 2

therefore the straight line equation is:

y = mx + b

y = 2x + 2

In the number 35.3816, the underlined three is __________ the other three.
Fantom [35]
Answer:
100 times bigger 

Explanation:
The given number is:
35.3186

Let's take a look at the first 3 on the left (the one in bold).
We will find that this 3 is in the tens position (10)

Now, let's take a look at the other 3 (the one directly after the point).
We will find that this 3 is in the tenth position (0.1)

Now, when multiplying the digit in the tenth position by 100, this digit would be in the tens position.
This means that the difference between the two positions is 100

Based on this:
The 3 in the tens position is 100 times greater than the 3 in the tenth position.

Hope this helps :)

Find the value of x.<br> PLEASE HELP ME!!!!!!!!!!
murzikaleks [220]

Solution:

<u>Step-1: Find the missing side length using Pythagoras theorem:</u>

  • 115² = 69² + x²
  • => 13225 = 4761 + x²
  • => 13225 - 4761 = x²
  • => 8464 = x²
  • => x = √8464 = 92

<u>Step-2: Find the area of the rectangle:</u>

  • Area of rectangle = LB
  • => 69 x (92 + 100)
  • => 69 x 192
  • => 13248 units²

HELP I NEED HELP ASAP
aev [14]

Answer:

  A (-2, 5)

Step-by-step explanation:

The attached shows the rectangle and the offered points. The point not on the rectangle is A(-2, 5).

__

If we examine the coordinates, we see that the y-values must be -2 or 3 for a point to be on the rectangle. Similarly, the x-values must be -2 or 5.

The offered point A has an appropriate x-value, but not an appropriate y-value. Point A is not on the rectangle.
