Answer:
3×22+3×54
as there's bracket, so c is the answer
All the blocks are total 100 (10x10), so the answer will be 72 of 100 or 72/100
4x - 2y ≤ 6 <em>subtract 4x from both sides</em>
-2y ≤ -4x + 6 <em>change the signs</em>
2y ≥ 4x - 6 <em>divide both sides by 2</em>
<h3>y ≥ 2x - 3</h3>
y = 2x - 3 - it's a linear function. We need only two points to plot the graph.
Choose any two values of x and calculate the values of y:
for x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)
for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1)

you re-write your eq as:
dx/dy -4(x/y) = 4y^5
the integrating factor is:
<span><span>e<span>−4∫dy/y</span></span>=1/<span>y^4
now solve it</span></span>
It would be exponential because you just plug in the values to each type of equation to get on that equals on both sides.
