For what values of h does the equation have real solutions. √(3x-h)= x+3

Mathematics
1 answer:
Andru [333]3 years ago
4 0

Square both side to get

3x-h = (x+3)^2

distribute the squared

3x - h = x^2 + 6x + 9

subtract 3x from both sides

-h = x^2 + 3x + 9

The answer will only have real solutions if the right side is factorable

h= -19, and 2.25 are both values that would make the right side factorable

3) An existing track is perpendicular to y=1/2x + 2 and passes through B(7,5)
stira [4]

Answer:

2. y=\frac{1}{2}x +3

Step-by-step explanation:

2. The line will be parallel to the current track which means they have the same slope. To write the equation, use the slope m=1/2 and the point (2,4) in point slope form:

y-y_1=m(x-x_1)\\y-4=\frac{1}{2}(x-2)

This is the equation of the line. You can convert it to slope intercept form:

y-4=\frac{1}{2}(x-2)\\y-4 = \frac{1}{2}x -1 \y=\frac{1}{2}x +3
