WebIdentify which equations have one solution, infinitely many solutions, or no solution. No Solution: 3z + 2.5 = 3.2y + 3z 4.5r = 3.2 + 4.5r One Solution: 1/2y + 3.2y = 20 2x + 4 = 3x + 1/2 Infinitely Many Solutions: 15/2 + 2z - 1/4 = 4z + 29/4 - 2z 1.1 + 3/4x + 2 = 3.1 + 3/4x Jessica is 5 years older than her sister Jenna. WebIn order to take your approach, you would need a variable to insert you selected value into the equation. If that had been the case, you would have an equation with one solution. 5=3 No solution because the number 5 will never equal the number 3. 5=3x you can …
WebA quadratic equation has one solution when the discriminant is zero. From an algebra standpoint, this means b 2 = 4ac. Visually, this means the graph of the quadratic (a … WebTo solve this equation for x, we can first isolate the absolute value term by adding 4 to both sides of the equation, which gives: 4 x − 3 = 9. Now we have an absolute value equation. To solve this equation, we need to consider two cases: one where 4x - 3 is positive, and one where 4x - 3 is negative. Case 1: 4 x − 3 ≥ 0.
