$y equals 2 x plus 4$
$y equals left parenthesis x minus 3 right parenthesis left parenthesis x plus 2 right parenthesis$
The system of equations above is graphed in the xy -plane. At which of the following points do the graphs of the equations intersect?

Note:
We can solve the equations by other methods too, but the method of substitution is most suitable here. Also, instead of solving
$x squared minus 3 x minus 10 equals 0$ by middle term factorisation, we could also use the quadratic formula, which is given by
$x equals fraction numerator negative b plus-or-minus square root of b squared minus 4 a c end root over denominator 2 a end fraction$
Where the standard form of equation is $a x squared plus b x plus c equals 0$

$y equals 2 x plus 4$
$y equals left parenthesis x minus 3 right parenthesis left parenthesis x plus 2 right parenthesis$
The system of equations above is graphed in the xy -plane. At which of the following points do the graphs of the equations intersect?

Find the area of an isosceles trapezium ABCD, if the parallel sides are 6cm and 14 cm, its non parallel sides is 5cm each.

$fraction numerator x minus 2 over denominator 3 end fraction plus fraction numerator y minus 1 over denominator 4 end fraction equals 13 over 12$ and $fraction numerator 3 plus y over denominator 3 end fraction plus fraction numerator x minus 2 over denominator 2 end fraction equals 11 over 6$ Solve by using the elimination method.

Cylindrical vessel of diameter 9 cm has some water in it. A cylindrical iron piece of diameter 6 cm and height 4.5 cm is dropped in it. After it was completely immersed, find the rise in the level of water.

During mineral formation, the same chemical compound can be come different minerals depending on the temperature and pressure at the time of formation. A phase diagram is a graph that shows the conditions that are needed to form each mineral. The graph above is a portion of the phase diagram for aluminosilicates, with the temperature t , in degrees

Which of the following systems of inequalities best describes the region where sillimanite can form?

Note:
We do not have the exact inequalities in the option, so we choose the one from the options which is the closest approximation of the inequalities that we have calculated. There are a couple of formulas and concepts used here, such as the equation of a line passing through two points and the concept that the region below a line is given by replacing the equality sign with less than or equal to in the standard form of the equation and vice versa.
