The slope is 4/5 and the y intercept is 1. To graph the equation start at 1 because that is where the graph crosses the y axis and go up 4 and over to the right 5 since the slope is positive.

Which linear equation has no solution? 23(9x+6)=6x+4
stiks02 [169]

Answer:

Step-by-step explanation:

23(9x+6)=6x+4

Expand it

207x+138 = 6x+4

Simplify it

201x = -134

Divide everything by 201

x=-134/201

Simplify it again

x=-2/3

Form a quadratic polynomial whose zeroes are 3-√3/5 and 3+√3/5?​
barxatty [35]

Answer:

x^2 -6x + 222/25

Step-by-step explanation:

If the zeros are as above, then ;

x = 3-√3/5 or x = 3 + √3/5

Firstly, let’s represent √3/5 by b

Thus;

The two roots are ;

x = 3-b or x = 3 + b

so;

x+ b -3 and x -3-b

The quadratic equation is the product of the two

(x + b-3)(x - b -3)

x(x - b-3) + b(x -b -3) -3(x - b -3)

= x^2 -bx -3x + bx -b^2 -3b -3x + 3b + 9

Collect like terms and we are left with;

x^2 -6x -b^2 + 9

So let’s put back b = √3/5

x^2 -6x -(√3/5)^2 + 9

x^2 -6x -3/25 + 9

x^2 -6x + 222/25
