Sehingga, himpunan selesaian dari pertidaksamaan |3 x + 2|/4 ≤ 1 adalah { x | –2 ≤ x ≤ 2/3, x bilangan real}. Selanjutnya, perhatikan pertidaksamaan |2 x – 7| < –5. Karena nilai mutlak dari setiap bilangan ... Algebra. Solve for x log of 7-2x=-1. log(7 − 2x) = −1 log ( 7 - 2 x) = - 1. Rewrite log(7− 2x) = −1 log ( 7 - 2 x) = - 1 in exponential form using the definition of a logarithm. If x x and b b are positive real numbers and b ≠ 1 b ≠ 1, then logb(x) = y log b ( x) = y is equivalent to by = x b y = x. 10−1 = 7−2x 10 - 1 = 7 - 2 x. Explanation: The x-intercept is the value of x when y=0, so plug in zero for y, and solve. 2x+5(0)= 3 2x= 3 ... 2x+7y=0 Geometric figure: Straight Line Slope = -0.571/2.000 = -0.286 x-intercept = 0/2 = 0.00000 y-intercept = 0/7 = 0.00000 Step by step solution : Step 1 :Equation of a Straight ... 2x+7y=3 Geometric figure: Straight Line Slope ...
