Answer:
Let x be the number of 3- point questions and y be the number of 5-points questions.
Step-by-step explanation:
The GCF of a polynomial is the greatest factor which is common to all the terms of the polynomial.
Thus, an example of a polynomial with a GCF of 2y is

The above polynomial can also be rewritten as

This form of the polynomial is obtained by factoring out the GCF of the polynomial.
<span>1/(4p)(x-h)^2+k=0
</span><span>1/(4p)(x-h)^2 = -k
</span>
<span>k(4p)(x-h)^2+1=0
4kp (x^2 - 2xh + h^2) + 1 = 0
4kp x^2 - 8kph x + 4kph^2+1 = 0
D = (-8kph)^2 - 4(4kp)(4kph^2+1) = 64(kph)^2 - 64(kph)^2 - 16kp
D = -16kp < 0
SO discriminant is always less than 0

Answer:
y= -1/2x-1
Step-by-step explanation:
1) put the equation in y-intercept form to find the slope of the original line 2x+4y=8
y=8/4-2x/4
y=2-1/2x
slope of second line will be -1/2
2) put point into the point-slope form (2,-2)
y-(-2)= -1/2(x-2) now simplify
y+2= -1/2x+2/2
y+2 = -1/2x + 1
y+2-2=-1/2x + 1 -2 ====>>>> y= -1/2x-1
