Step-by-step explanation:
since the two lines are parallel, slope of the line is Sam so it's 3.
let eqn of the line be y = 3x + b.
sub (4, -2):
4 = 3(-2) + b
b = 10
therefore, equation of the line is y = 3x + 10

Answer:
We let x be the number of hours both could the job together.
The fraction of the job done by Elias is
x/40
The fraction of the job done by Niko is
x/50
Together they would be able to finish the job
x/40 + x50 = 1
x = 1 / (1/40 + 1/50)
x = 22.22 min

Answer:
37.44 cm²
Step-by-step explanation:
To find the width, follow these steps.
10.4*2=20.8
28-20.8=7.2
7.2/2=3.6
The width is 3.6.
To find the area, multiply the width and the length together.
10.4*3.6=37.44
The area of the rectangle is 37.44 cm²
Hope this helps!
Answer:
200.3 cm
210 cm
Step-by-step explanation:
to find the mean add all the numbers up and then divide it by the total number sampled
so we have
(198+199*3+200*2+201*5+202*2)/13
which gives you around 200.3
To find the height of the new player we have the following equation
let x be the height of the new player
solve for x and get
210 cm
