The answer must be B Step-by-step explanation:
The options you provided are unclear to me, so I will respond in general terms: to determine if a point (ordered pair) lies on a line, you need to substitute the x-value from that pair into the line's equation and check if the resulting y-value matches the y-value of the ordered pair. For example, if your line is y = 4/3x + 1/3, we can check if (0, 0) and (2, 3) fit this line. We find that y = 4/3·0 + 1/3 gives us 1/3, which does not equal 0, indicating (0, 0) is not on the line. For (2, 3), substituting yields y = 4/3·2 + 1/3 = 3, meaning (2, 3) is on the line.
Answer:
Step-by-step explanation:
a) According to the included image, the smaller section measures 16ft², and the larger section is 50 ft². The formula for the area of a square is side × side = side².
For the smaller section: Area = side²
16 = side²
side = √16 = 4 ft
For the larger section: Area = side²
50 = side²
side = √50
The overall length of the shed is the small area plus the large area = 4 + √50
The total length of the shed equates to 4 + √50
b) All square roots of integers unless they are perfect squares are irrational numbers, thus 4 + √50 is irrational. All such values fall within the set of real numbers, categorizing 4 + √50 as an irrational and real number.
