Answer:
where is the question at
Step-by-step explanation:
At first we will find the slope of the line that <span>passes through the points A and B
</span>
<span>A ( -10,8), B(2,3)
slope = (Δy)/(Δx) = (3-8)/(2-(-10)) = -5/12
the require line is parallel to the line </span><span><span>passes through the points A and B
</span>∴ the slope of the line </span><span>that passes through Point X = -5/12
and have a general form
y = m x + c
where m is the slope and c is constant
the constant can be calculated by substituting with the point x (-5,10) in the equation of general form
∴ 10 = (-5/12)*-5 + c
c = 10 - 25/12 = 95/12
∴ y = (-5/12)x +95/12 ⇒⇒⇒⇒ multiplying the equation by 12
∴ 12y = -5x +95

Answer:
Difference in area of the last square and the initial square = 440 cm²
Step-by-step explanation:
Length of the side of a square = 1 cm
Area of the square = (side)² = 1 cm²
Addition of side length every minute = 2 cm
After x minutes length of each side of the square = (1 + 2x) cm
If x = 10 minutes
Length of each side of the square = [1 + 2(10)]
= 21 cm
Area of the square after 10 minutes = (21)²
= 441 cm²
Therefore, difference in area of the last square and area of the initial square
= 441 - 1
= 440 cm²
To find the circumference, we will have to multiply the length of the diameter by pi
Mathematically, we have this as;
Brandon's backpack weighs = 3140 grams.
We know, 1000 grams in a kilogram.
Therefore, 3140 grams = 3000 grams + 140 grams = 3 kilogram 140 grams.
Brandon weighs(without backpack) = 22 kg 610 grams more than his backpack.
More than pharse represents addition.
22 kg 610 grams more than backpack weighs = 22 kg 610 grams + 3 Kg 140 = 25 Kg 750 grams.
Therefore, Brandon weighs(without backpack) = 25 Kg 750 grams.
Total weight of Brandon weighs and backpack weighs = Brandon weighs(without backpack) + backpack weighs.
= 25 Kg 750 grams + 3 Kg 140 grams
= 28 Kg 890 grams.
Therefore, Brandon got 28 Kg 890 grams on a scale when wearing his backpack.
