Pls solve this simultaneous step by step :
3a + 2b = 6
3b - 2a =10

Step-by-step explanation:

The simaltaneous equation are:

● 3a + 2b = 6

● 3b - 2a = 10

Graph both equations

While graphing use x instead of a and y insread of b in the graphing tool

The solutions are the coordinates of the intetsection point between the two lines.

The intersection point coordinates are approximatively (-0.15,3.2) picture below

Wich means:

● x = a = -0.15

● y = b = 3.2

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
