Initially we have two unknown variables, so we want to eliminate one of the variables (x) to solve for the other (y). The LCM of 6 and 4 is 12, so multiply each equation such that the coefficient of x is ...
The vector equation of any line is composed of the addition of a point on the line and some distance in the direction of the line, in the form y=(x,y,z) +d(x_1, y_1, z_1), where (x,y,z) is any point on th...
7x = 4yx=4y/7If we insert this into our other equation.4y/7 + y = 8811y/7 =88y = 56As we knowx =4y/7X= 4*56/7 = 32Then we can work out the answer X - Y = 32 - 56 = -24
f(x)=(x3-2x)5If we look at this function, we can see that it can be split into two functions, one hiding in the other one. Because of that, to solve this problem we will need t...
The integral can be split into two different functions of x which is a hint that we must use the integration by parts method. The method is defined as WHAnswered by William H. • Maths tutor3918 Views
