Answers

Equation Answer: y= -2x -7

Answer:

y = -1/2x -7

Step-by-step explanation:

. The slope of the line (rise over run) goes down so it's negative and it you go down (bc it's negative slope) 1 and go over 2 so it would be -1/2

. B stands for the y intercept so it would be -7 because the line goes through -7 on the vertical line.

Jeff is studying abroad in Sussex England this summer. He wants to visit a local museum outside of town this weekend. A taxi cab in London costs £2.70 pounds plus 0.20 pence per kilometer traveled if you use the Queen’s Cab Company. If you use the Royal Cab Company they will charge you £1.55 pounds plus 0.35 pence per kilometer. Which cab company should Jeff use?

Answers

Answer:

if it's less than 7.66km use Royal, if more than 7.66 use Queen's

Step-by-step explanation:

To get the answer you can set up mutliple equations

For Queen's Cab Company

2.70 + 0.20x = ?

for Royal Cab Company

1.55 + 0.35x = ?

Since you didn't give a distance which is what will determine which is cheaper we can solve as a set of equations.

2.70 + 0.20x = 1.55 + 0.35x

1.15 = .15x

x = 7.66

So this lets you know that at 7.66 km Royal cab company becomes more expensive due to their pence per km.

So if it's less than 7.66km use Royal, if more use Queen's

If you fold a number line so that a vertical crease goes through 0, the points you label would match up. Explain why this happens.

Answers

It would happen because 5 is 5 4 is 4 3 is 3 2 is 2 1 is 1 and 0 is only one number 0.

If we fold a number line so that a vertical crease goes through 0, the points will match up for the same because of the same distance on both sides from zero.

What is a number line?

A number line is a straight line representing numbers on it either vertically or horizontally.

If we fold a number line so that a vertical crease goes through 0, the points will match up for the same. this is due to the reason the points on a number line from zero are at the same distance on both sides so, the numbers will superimpose on each other when folded vertical through 0.

Since the distance of 1 and -1 is the same as zero so 1 would match -1.

Similarly for -2 and 2, -3 and 3, etc.
