Could someone please explain how to plot the x-intercept of the first equation and what the answer would be?

You would start in the middle of the number line, move right to positive 4x then move up 2 units to land right in line with 2y this is where your plot would be.

Step-by-step explanation:

Hope this helps mark brainliest please!

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
