Math Algebra A radioactive substance decays in such a way that the amount of mass remaining after t days is given by the function m (t) = 14e-0.014+ where m (t) is measured in kilograms. (a) Find the mass at time t = 0. kg (b) How much of the mass remains after 43 days? WebSolve the simultaneous equations \(x + y = 5\) and \(y = x + 1\) using graphs. To solve this question, first construct a set of axes, making sure there is enough room to plot the two graphs.

WebSolve each of the following given systems of equations graphically and find the vertices and area of the triangle formed by these lines and the y - axis: 2x – 5y + 4 = 0, 2x + y – 8 = 0. Answer: We can rewrite the equations as: 2x – 5y = - 4 & 2x + y = 8. For equation, 2x – 5y = - 4. First, take x = 0 and find the value of y. WebThe second inequality is y is less than 2x minus 5. So if we were to graph 2x minus 5, and something already might jump out at you that these two are parallel to each other. They have the same slope. So 2x minus 5, the y-intercept is negative 5. x is 0, y is negative 1, negative 2, negative 3, negative 4, negative 5. small shower tent

Solve the following system of equations graphically: 2x – 3y + 6 = 0 and 2x + 3y – 18 = 0 Also, find the area of the region bounded by these lines and y-axis. Solution: Given that, 2x – 3y + 6 = 0 and 2x + 3y – 18 = 0. Now, 2x – 3y + 6 = 0. y = (2x + 6)/3. When x = 0, we get y = 2. When x = -3, we get y = 0 small shower system
