Using proportions, it is found that the coordinates of point B are given as follows:
A. (1.6, 0).
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Point B is 3/4 of the way from AB to AC, hence:
The points are:
Then, to find the x-coordinate:
x + 2 = 3.6.
x = 1.6.
For the y-coordinate:
y + 3 = 3
y = 0.
Hence option A is correct.

25.
The area is b * h, so
(2x + 7) * 4
which is greater than 100 units, so
(2x + 7) * 4 ≥ (don't look at =; only major) 100
8x + 28 ≥ 100
8x ≥ 100 - 28
8x ≥ 72
x ≥ 9
26.
The perimeter is 2 * (b + h), so
2 * (2x + 7 +4) = 2 * (2x + 11)= 4x + 22
which is greater than 50 units, so
4x + 22 ≥ (don't look at =; only major) 50
4x ≥ 50 - 22
4x ≥ 28
x ≥ 7
Answer:
31.5 m^2
Step-by-step explanation:
To find the amount for 7 bags, create a proportion.
To solve for y, cross multiply numerator to denominator of each fraction.
4(y) = 18(7)
4y= 126
y= 31.5
7 bags will do 31.5 m^2
Answer:
Y= -X + 9 Can be found by trials
