The work of a student to solve a set of equations is shown
Equation A y = 15 - 22
Equation B: 3y = 3 - 42
Step 1: -3y) = -3(15 -22) (Equation A is multiplied by-3.]
3y = 3-4 Equation B]
Step 2: -3y = 15-22 (Equation A in Step 1 is simplified)
3y = 3 - 42 [Equation B]
Step 3: 0= 18-62 Equations in Step 2 are added]
Step 4: 62 = 18
Step 5: Z=3
In which step did the student first make an error?
Step 4
Step 3
Step 2
Step 1

An object is translated by (x + 4, y - 2). if one point in the image has the coordinates (5, -3), what would be the coordinates of its pre-image? (9, -5) (1, -5) (9, -1) (1, -1)

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
