Consider the line 2x+8y=8.

What is the slope of a line
parallel to this line?

What is the slope of a line perpendicular to this line?

Answers

Answer: parallel = - 1/4

Step-by-step explanation: perpendicular= 4

Answer:

Parallel = -1/4 ; Perpendicular = 4

Step-by-step explanation:

First, I'll put the line into slope-intercept form.

2x + 8y = 8

8y = -2x + 8

y = -1/4x + 1

Now we know that the slope is -1/4.

A parallel line would have the same slope of -1/4.

A perpendicular line would have a slope of 4.

Find the slope intercept equation of the line.

Answers

The equation for the slope interception is 1/5

A Porsche uses 2.5 litres of fuel every 2 kilometres it travels. How much fuel does it use if it travels 50 kilometres​

Answers

2.5/2 = 1.25 litres per kilo
1.25 * 50 = 62.5 litres

Solution: 62.5 litres of fuel

Answer:

The Porsche uses 62.5 liters in 50 kilometers

Step-by-step explanation:

Amount of fuel Porsche uses = 2.5/2 liters/kilometer

                                                  = 1.25 L/Km

         Distance to be travelled = 50 kilometer

Amount of fuel used in 50 km = 1.25 * 50

                                                  = 62.5 Liters

Therefore the Porsche uses 62.5 liters in 50 kilometers

LCM of 189024
please give me answer my question​

Answers

Answer:

360

Step-by-step explanation:

We need to find the LCM of 18,90 and 24.

The prime factorization of 18 = 2 × 3 × 3

The prime factorization of 90 = 2 × 5×3×3

The prime factorization of 24 = 2 × 3×2×2

LCM is least common multiple.

LCM = 2 x 2 x 2 x 3 x 3 x 5

= 360

Hence, the LCM of 18,90 and 24 is 360.
