The initial value of the car is 18000. To subtract 25% of 18000 one must times 18000 by 0.75 which equals 13500. Next, one must times 13500 by 0.88 to the power of 4 which equals 8095.89 to 2 decimal plac...
To solve this problem we're going to use an equation. First let's write down the information that we do know.Let's use (r) for ruler and (c) for crayon.So 7 rulers and 15 crayons cost £7 (or 700 pen...
First write out the general equation, y = mx + c where m = gradient and c = the Y-interceptFind the gradient m= change in y/change in xM= (-4,-6)/(9-4) = (-10)/(5) = -2Find c by substituting in either of ...
To expand is just to multiply out. We will multiply everything inside the bracket by everything inside so it becomes2a x 4 + 2a x aThen we use bidmas to get:8a + 2a^2
Step 1) Write out the general equation of a straight line: y = mx + c where m is the gradient and c is where the line intersects the y-axis. Step 2) Find the gradient: m...
