Answer:

(0,5)

Step-by-step explanation:

Just plug them in:

2x - y = 10

- 2 (0) - (5) = 10?

no because 2 x 0 is 0. That would mean -5 = 10. which isn't true

- 2 (10) - (10)?

yes because 2 x 10 is 20. Subtract 10 from that and you get 10. so 10 =10

- 2 (5) - (0)?

yes because 2 x 5 is 10. There is nothing to subtract from 10 so you get 10. 10 =10.

AB is parallel to CD, and EF is perpendicular to AB

The number of 90° angles formed by the intersections of Ef and the two parallel lines AB and CD is ____

Answer:

The number of 90° angle formed = 8 angles

Step-by-step explanation:

From the question and attached diagram, the following information is given:

AB is parallel to CD

EF is perpendicular to AB

Required: number of 90° angles formed by the intersection of the perpendicular line and the parallel lines.

<em>Note, the angle formed between a line and a perpendicular line = 90°</em>

From the diagram:

Number of 90° angle formed by intersection of perpendicular line EF and line AB = ∠1, ∠2, ∠3 and ∠4 = 4 angles

Number of 90° angle formed by intersection of perpendicular line EF and line  CD = ∠5, ∠6, ∠7 and ∠8 = 4 angles

Total 90° angles formed by perpendicular line with lines = ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7, and ∠8 = 8 angles

Tom rode his horse for 4/6 mile. Liz rode her horse for and equal distance. what is an equivalent fraction that describes how fa
Tpy6a [65]
I saw the images that accompanied this problem. 

2 circles: circle 1 has 6 slices ; circle 2 has 3 slices

Circle 1 is for Tom: you can shade 4 slices out of the 6 slices.
Circle 2 is for Liz: you can shade 2 slices out of the 3 slices.

4/6 is equal to 2/3 because when 4 and 6 are both divided by 2, they give quotient of 2 and 3, respectively.

4 ÷ 2 = 2
6 ÷ 2 = 3
