The required coordinate of A will be at (-4, 0)
When a point bisects a line, it cuts the line into two equal parts and the point on that line is known as its midpoint. The expression for calculating the midpoint of a line is expressed as;
![M(X, Y)= [{ \frac{x_2+x_1}{2} , \frac{y_2+y_1}{2} ]](https://tex.z-dn.net/?f=M%28X%2C%20Y%29%3D%20%5B%7B%20%5Cfrac%7Bx_2%2Bx_1%7D%7B2%7D%20%2C%20%5Cfrac%7By_2%2By_1%7D%7B2%7D%20%5D)
where:
From the question, we are given the following coordinate points
Get x₂;
Get y₂;
Hence the coordinate of A will be (-4, 0)

For any value, e.g. a, to the nearest x units, the upper and lower bounds are:
(a + x/2) and (a - x/2)
For your question, there are three dimensions so:
Dealing with the first one, we have 24 cm to the nearest 2 cm so the boundaries are:
Upper boundary: 24 + 2/2 = 25
Lower boundary: 24 - 2/2 = 23
The second dimension is the same as the first in value and is also given to the nearest 2 cm so the boundaries are the same as for the first.
The third dimension is 20 cm to the nearest 2 cm so the boundaries are:
Upper boundary: 20 + 2/2 = 21
Lower boundary: 20 - 2/2 = 19
To get the largest possible area, we take the upper bounds of all the dimensions and multiply them so:
25 * 25 * 21 = 13125 cm³
Answer:
Step-by-step explanation:
Put the ordered pairs into the slope formula x=y2-y1/x2-x1 then you will get your slope of the line. once you have your slope pick an ordered pair and put it in point slope y-y1=m(x-x1) distribute and you will get your answer.
Answer:
Total amount she spent on the posters = $43.2 + $10.8 = $54
Step-by-step explanation:
Lila bought a green poster that measured 36 inches by 24 inches and a red poster that measured 12 inches by 18 inches. The posters cost per square inch is $0.05 .
To know how much she spend on the posters one have to convert the measured values of the posters to square inches(area).
Green poster
area of rectangle = Lb
area of rectangle = 36 × 24
area of rectangle = 864 square inch
since 1 square inch = $0.05
864 square inch = ?
cross multiply
864 × 0.05 = $43.2
Red posters
area of rectangle = Lb
area of rectangle = 12 × 18
area of rectangle = 216 square inches
since 1 square inch = $0.05
864 square inch = ?
cross multiply
216 × 0.05 = $10.8
Total amount she spent on the posters = $43.2 + $10.8 = $54
