6 students are 6th graders
Step-by-step explanation:
27/9 = 3
3•2=6
x2 + y2 – 8x + 12y – 5 = 0?
Answer:
radius:
Step-by-step explanation:
by using the quadratic equation.
Answer:
Step-by-step explanation:
Here the coefficients of this quadratic equation are {7, -1, -3}. Note that the given equation must be rewritten in standard form: 7x^2 - x - 3.
Then the discriminant, b^2 - 4ac, is (-1)^2 - 4(7)(-3), or 1 + 84, or 85. Because this discriminant is positive, the given quadratic has two real, unequal roots. These roots are:
-(-1) ± √85
x = ------------------
14
or:
1 ± √85
x = ------------------
14

the y intercept is 1
the slope is (y2-y1)/(x2-x1)
m = (0-1)/(6-0) = -1/6
the equation of the line is y = mx+b
y = -1/6x+1
the graph is shaded above y>
the line is dotted so no equals
y> -1/6x+1
