Answer:
I don't know, I'm so sorry but can you respond at my question?
Answer:
40 more inches of fabric is needed to cover the entire table.
Step-by-step explanation: you add ten inches to every end of the table
Number the tables as follows:
1 2
3 4
Eliminate 3 and 4 immediately, because for x = 2 the y values are wrong (3 and 1).
In tables 1 and 2, the input (1) produces the correct output (-1).
So we have to determine which table agrees 100% with the system of equations given.
Comparing tables 1 and 2, row by row, we see that their contents are the same EXCEPT for the first rows. So focus on determing which of those 2 rows displays values that satisfy both given equations.
First I looked at y=2x-5, and subst. -1 for x. I got -7, which is correct in table 1 but not in table 2 (where the value would be -13).
Thus, table 1 correct represents the solution of the system of equations.
Answer:
- area of rectangle: 48 cm²
- area of triangle: 18 cm²
- shaded area: 30 cm²
Step-by-step explanation:
The area of a rectangle is given by the product of its length and width.
... A = LW
For your rectangle, the overall area is ...
... A = (12 cm)(4 cm) = 48 cm² . . . . rectangle area
___
The area of a triangle is half the product of its base and height. Your triangle is shown with a base of 9 cm, and its height is the height of the rectangle, 4 cm. The triangle area is ...
... A = (1/2)bh
... A = (1/2)(9 cm)(4 cm) = 18 cm² . . . . triangle area
___
The shaded area of the figure is the difference between the rectangle area and the triangle area. (The triangle is fully included in the rectangle, but is not shaded.) That difference is ...
... shaded area = rectangle area - triangle area
... shaded area = 48 cm² - 18 cm² = 30 cm² . . . . shaded area
