We are given with:
Average height of plants to be at least 73 inches
Three plants with heights of
70, 71, 72
The inequality that can be used to determine the possible heights of the fourth plant is:
(70 + 71 + 72 + x) / 4 ≥ 73
Solving for x
x ≥ 79
Answer:
Sketch the following three graphs:
1) y = (x - 5)²
2) y = -(x - 5)²
3) y = x - 5
First two are parabolas with vertex at (5,0)
Third one is a line which intersects both the parabolas as (5,0)
Answer:
56x² + 2xy+ 3y²
Step-by-step explanation:
81x²+18xy+18xy+4y² - (25x²+10xy+y²) = 56x² + 2xy+ 3y²
The value of the expression to the nearest tans is -8.4
<h3>What is rounding a number?</h3>
Adjusting a number's digits so that it produces an approximation of a result is known as rounding
The given expression is -8 (5/12).
Rewrite the expression:
-8 (5/12)
= - 101/12
= - 8.4
Hence, the value of the expression to the nearest tans is -8.4
