Question

Find the product of both functions: y= 2x - 1 y = -x + 2

Answer 1

Answer:

0.375

Step-by-step explanation:

1.y=2x-1

2.y=-x+2

using substitution method

1.y=2x-1

y+1=2x

the other equation where there is an x will be replaced by a the first equation

so

2.y=-(y+1)+2

y=-y-1+2

y=-y+1

y+y=1

2y=1

2y/2=1/2

y=0.5

the value of y is 0.5 the value of x would be found by taking the y and replacing it with 0.5 in any of questions one and two.

1.y(0.5)=2x-1

0.5=2x-1

0.5+1=2x

1.5=2x

1.5/2=2x/2

0.75=x

the value of y is 0.5 and x is 0.75

0.5*0.75=0.375

=0.375
