Answer:
Which two expressions?
Step-by-step explanation:
Question 13-18 & 22-27 will all be answered the same way, so i will walk you through question 13: (6,4) y=3x-2
(x,y)=(6,4)
now that we know the first number in the parenthesis is the x value and the second number in the parenthesis is the y value we can plug it into the equation. (x=6,y=4)
4=3x-2 (add two to each side)
4+2=3x
6=3x (divide 3 from each side)
x=2
---------------
y=3(6)-2
y=18-2
y=16
-------------------
answer: (2,16)
now apply the same principles to the other problems!!! hope this helped!!!
Answer:
48.3 cm^2
Step-by-step explanation:
The area of the enclosing square is that of a square 15 cm on a side, so is ...
square area = (15 cm)^2 = 225 cm^2
The white area is that of a quarter-circle of radius 15 cm, so that area is ...
quarter-circle area = (1/4)πr^2 = (π/4)·(15 cm)^2 = 56.25π cm^2 ≈ 176.7 cm^2
Then the yellow area is the difference ...
yellow area = square area - quarter-circle area
= (225 cm^2) - (176.7 cm^2)
yellow area = 48.3 cm^2
Answer:
40x-11
Step-by-step explanation:
The more plot point the better but you must have at least three points, a labeled X-axis and Y-axis, and a table for the data to be organized into.
