To get from the post office to the library, Sindy walked due north and then due east. The distance Sindy walked east is 20 meters more than the distance she walked north. If Sindy were able to walk directly from the post office to the library in a straight line, she would have walked 150 meters. Suppose x represents the distance Sindy walked north. Which equation can be used to find x?x^2 (x 20)^2=150^2
202=x^2-150^2
x (x 20)=150
x^2 (x 150)^2=20^2

Answers

Answer 1

Answer:

Answer:

x² + (x + 20)² = 150²

Step-by-step explanation:

Sindy walked x meters in north and then x+20 meters toward east. If Sindy were able to walk directly from the post office to the library directly in a straight line, the distance she would have walked 150 meters.

Thus Sindy forms a right angle triangle as in the figure attached.

From Pythagoras theorem

x² + (x + 20)² = 150²

This is the equation we can use to find x.

Answer 2

Answer: Technically, none of the equations.

The equation you're looking for would be:

x²+(x+20)²=150²

Slope = 3/2, or 1.5

Step-by-step explanation:

Pick out the lattice points ( points that intersect the graph markings)

I see 2 points, ( 3, 1), and ( 5, 4)

Slope = Δy/xΔ = 4 - 1/5 - 3 = 3/2

Slope is 3/2, or 1.5

The scatter plot represents the purchase prices and selling prices of X-ray machines made by five different manufacturers. Which of the following points show errors of prediction or residuals?Answer Choices :
Points (14, 25) and (15, 25)
Points (15, 25) and (18, 26)
Points (14, 25) and (16, 25)
Points (12, 24) and (18, 26)

Answers

The points on the scatter plot show the different predictions. The straight line drawn is called the line of regression. Errors in prediction for each point can be determined by drawing a vertical line from the point to the line of regression. As seen in the image, all of the prediction points are found on the line except for points (14,25) and (16,25). Therefore, these points contain errors in prediction.

How do you solve x + 1/4x = 15.

Answers

x + 1/4x = 15
4/4x + 1/4x = 15
5/4x = 15
5x = 60
x = 12

x+(1/4)*x = 15 // - 15

x+(1/4)*x-15 = 0

5/4*x-15 = 0 // + 15

5/4*x = 15 // : 5/4

x = 15/5/4

x = 12
