your equation is this...
2x < y + 7
Now solve for y...
2x - 7 < y
Since you have two variable the most you can get out of (y) is the graph and the y-intercept.
the y-intercept is y > -7
Yes
so = -4y < -20 making y < 5
It cannot be solved because the discriminant of the quadratic equation is less than zero
This quadratic equation has no solutions because the discriminant is less than zero.
Correct.
Yes
No because the discriminant of the given quadratic expression is less than zero.
The equation 7x-12 is less than 4x plus 36 means just what it says7x - 12 less than 4x + 36To solve this, treat it like ordinary algebra and solve for x, replacing the equals sign with the less than sign. Remember that if you multiply or divide by a negative number, then the less than sign flips over and becomes the greater than sign.7x - 12 less than 4x + 367x less than 4x + 487x - 4x less than 483x less than 48x less than 16
so = -4y < -20 making y < 5
It cannot be solved because the discriminant of the quadratic equation is less than zero
9h + 2 < - 79 9h < - 81 h < - 9
This quadratic equation has no solutions because the discriminant is less than zero.
Correct.
A = 5 + 3*b To solve for b, rewrite as b = (A - 5) / 3
