Answer:

Hence, we get the equation on elimination as:

10b=60

( Also a= -1 and b=6)

Step-by-step explanation:

We have to use the elimination method to solve the following system of equation with variables a and b:

5a+5b=25 -------(1)

-5a+5b=35-------(2)

Clearly on adding equation (1) to (2) we get:

      5a+5b=25

     -5a+5b=35

  ---------------------------

     0+10b=60

i.e. 10b=60 is the equation that we obtain and on solving this we obtain:

b=6 ( since on dividing both side of the equality by 10)

Also, on putting value of b in equation (1) we obtain the value of a as:

5a+5×6=25

5a+30=25

5a=25-30

5a=-5

Hence, a= -1.

I need help with this..
Misha Larkins [42]

Answer:

a0) 2

  x<0

a1) x

   0≤x<3

a2) 3

     x≥3

Step-by-step explanation:

As shown in the given graph

function of y is a straight line at y=2 line till x=0

hence a0:

y= 2 for x<0

Then function becomes linear line from x=0 till x=3

hence a1:

y= x for 0≤x<3

Now after that graph of function y again shift to straight line from x=3 onward with y-axis value of 3

hence a2:

y= 3 for x≥3 !
