What is the value of x if 3x - 5 = 7?

To find the value of x, you can first add 5 to both sides of the equation to isolate the variable: 3x - 5 + 5 = 7 + 5, which simplifies to 3x = 12. Then, divide both sides by 3 to solve for x: 3x/3 = 12/3, giving x = 4. Therefore, the value of x is 4.

Solve the equation 2(x + 4) = 14.

To solve the equation 2(x + 4) = 14, first distribute the 2 on the left side to get 2x + 8 = 14. Then, subtract 8 from both sides to isolate 2x and get 2x = 6. Finally, divide by 2 on both sides to find x = 3. Therefore, the solution to the equation is x = 3.

Find the slope of the line passing through the points (3, 2) and (5, 7).

To find the slope of the line passing through the points (3, 2) and (5, 7), we use the formula for slope, which is (y2 - y1) / (x2 - x1). Substituting the coordinates, we get (7 - 2) / (5 - 3) = 5 / 2. Therefore, the slope of the line passing through these two points is 5/2.

Simplify the expression 3x^2 - 2x + 5 - (x^2 + 3x - 1).

To simplify the expression 3x^2 - 2x + 5 - (x^2 + 3x - 1), first distribute the negative sign within the parentheses to get 3x^2 - 2x + 5 - x^2 - 3x + 1. Combining like terms, we get 2x^2 - 5x + 6. Therefore, the simplified expression is 2x^2 - 5x + 6.

Solve the system of equations: 2x - 3y = 6 and 4x + 2y = 12.

To solve the system of equations, we can use the method of substitution or elimination. By solving simultaneously, we get x = 3 and y = 0 as the solution to the system of equations.

Graph the inequality y > 2x + 1.

To graph the inequality y > 2x + 1, start by plotting the line y = 2x + 1 as a dashed line. Then shade the region above the line, since the inequality is y > 2x + 1. This shaded region represents all the points that satisfy the inequality.

Find the value of y when x = -3 in the equation y = 2x^2 - 5x + 4.

Substitute x = -3 into the equation y = 2x^2 - 5x + 4: y = 2(-3)^2 - 5(-3) + 4 = 2(9) + 15 + 4 = 18 + 15 + 4 = 37. Therefore, when x = -3, the value of y is 37.

Determine the zeros of the quadratic function f(x) = x^2 - 4x + 3.

To determine the zeros of the quadratic function f(x) = x^2 - 4x + 3, we need to find the values of x where f(x) = 0. By setting f(x) to zero and solving for x, we get x^2 - 4x + 3 = 0. Factoring this quadratic equation gives us (x - 3)(x - 1) = 0. Therefore, the zeros of the function are x = 1 and x = 3.

Simplify the expression (3a^2b^3)^2.

The simplified expression is 9a^4b^6.

Solve the absolute value equation |2x - 6| = 10.

To solve the absolute value equation |2x - 6| = 10, first separate it into two equations: 2x - 6 = 10 and 2x - 6 = -10. Solving these equations separately, we get x = 8 and x = -2. Therefore, the solutions to the absolute value equation are x = 8 and x = -2.
