Which are the solutions of the quadratic equation?
Given: x2 = 7x + 4
x2 = 7x + 4
0 = -x2 + 7x + 4
Answer: x = (7 + √33) / 2
Answer:
y=-2x+3
Step-by-step explanation:
the points of intersect are (0,3) and (2,-1) then i made it into slope
3+1/0-2
4/-2
-2
substitute (0,3)
3=b
y=-2x+3
B hope you have a blessed day!
Answer:
y +2 = 2(x +3)
Step-by-step explanation:
The equation in point-slope form for a line with slope m through point (h, k) is ...
y -k = m(x -h)
The slope of your given line is the coefficient of x, -1/2. The slope of a perpendicular line will be the negative reciprocal of that: -1/(-1/2) = 2. So, you have m = 2, (h, k) = (-3, -2), and your desired equation is ...
y -(-2) = 2(x -(-3)) . . . . . . which can be simplified to ...
y +2 = 2(x +3)
