Answer:One way of knowing the correct answers, we substitute the ordered pairs to the function and see whether it would make the function true.
3x – 4y = 21
A. (−3, 3)
3(-3) – 4(3) = 21
-21 = 21 ---------------> not equal
B. (−1, −6)
3(-1) – 4(-6) = 21
21 = 21 ---------------> equal
C. (7, 0)
3(7) – 4(0) = 21
21 = 21 ---------------> equal
D. (11, 3)
3(11) – 4(3) = 21
21 = 21 ---------------> equal
Answer:
Part A: Describe how you can decompose this shape into triangles: If you draw a line from each vertex to the vertex at the opposite side of the hexagon, you will form 6 triangles.
Part B: What would be the area of each triangle: 62.4
Part C: Using your answers above, determine the area of the table's surface: 374 .4
Step-by-step explanation:
Part A: Describe how you can decompose this shape into triangles: If you draw a line from each vertex to the vertex at the opposite side of the hexagon, you will form 6 triangles.
Part B: What would be the area of each triangle: bxh /2
12 x 10.4 /2
Part C: Using your answers above, determine the area of the table's surface: 374.4
The correct answer would be ‘B’ because...
A rounds up to 277000
B rounds to 276000
C rounds to 275000
And D rounds to 275000 as well.

Answer: Paula starts with 301.5 yarns.
Step-by-step explanation:
Equation of a line passing through two points (a,b) and (c,d) is given by:-
Given: x= number of square inches knitted on the scarf
y= number of yarns remaining on the ball of yarn
The equation of a line passing through (15, 300.2) and (26, 177.88):
To find initial point, put x=0
Hence, Paula starts with 301.5 yarns.
Replace every x in the function with a -2. 3(-2)^2 - 2(-2) + 7. Simplifying gives you 3(4) + 4 + 7. Do the math now. 12 + 4 + 7 = 23
