1 Answer 1 vote Standard from of an equation is ax by c = 0 1) y 3 = 1/2 (x 6) Cross multiplication 2y 6 = x 6 x 2y = 0 2) y 4 = 2/3 (x 5)Therefore, cost of one pencil = Rs 3 and cost of one pen = Rs 5 2 On comparing the ratios 2, b 1 /b 2 and c 1 /c 2, find out whether the lines representing the following pairs of linear equations intersect at a point, are parallel or coincident Answer (i) 5x – 4y 8 = 0 7x 6y – 9 = 0 Comparing these equation with a 1 x b 1 y c 1 = 0 a 2 x b 2 y c 2 = 0 Ex 36, 1 Solve the following pairs of equations by reducing them to a pair of linear equations(i) 1/2𝑥 1/3𝑦 = 2 1/3𝑥 1/2𝑦 = 13/6 1/2𝑥 1/3𝑦 = 2 1/3𝑥 1/2𝑦 = 13/6Let 1/𝑥 = u 1/𝑦 = v So, our equations become1/2 u 1/3 v = 2 (3𝑢 2𝑣)/(2 × 3) = 2
The Substitution Method
1/0=0/0=z/0= tan(\\pi/2) =log 0 =0 and (z^n)/n = log z for n=0 exp(1/z) =1 for z=0。 基本的な関数 y=1/x の原点に於ける値は ゼロである。無限遠点がゼロで表される。ゼロの意味の新しい発見である。 これらの数学の素人向きの解説は 55カ月に亘って 次で与えられている： ベストアンサー x2乗＋ (y 3√x2乗)2乗＝1 とありますが，3は係数ではなく 正しい式は x² (y∛x²)²=1 ① で，♡を描きたいのでしょう． ①は陰関数ですが， dy/dx=0 という方程式の実数解を正確に求めることができなければ，増減の様子が分からず，微分法を用いてグラフを描くことはできません． 実際にその計算を行ってもらえばよいのですが 計算は困難で，dy/dxA x 2 b x c a x 2 b x c の形を使い、 a a, b b, c c の値を求めます。 a = 1 2, b = 0, c = 0 a = 1 2, b = 0, c = 0 放物線の標準系を考えてみましょう。 a ( x d) 2 e a ( x d) 2 e Substitute the values of a a and b b into the formula d = b 2 a d = b 2 a d = 0 2 ( 1 2) d = 0 2 ( 1 2) 右側を簡略化し
