A quadratic function is defined by f(x) = 3x^2 + 4x - 2. A linear function is defined by g(x) = mx-5. What values of the slope o
irakobra [83]
You need to find points where the line g(x) intercepts the quadratic function f(x) in one and only one point.

Then 3x^2 + 4x -2 = mx - 5

solve 3x^2 + 4x - mx -2 + 5 = 0

3x^2 + (4 - m)x + 3 = 0

In order to there be only one solution (one intersection point) the radicand of the quadratic formula must be 0 =>

b^2 - 4ac = (4 - m)^2 - 4(3)(3) = 0

(4 - m)^2 = 24

4 - m = +/- √(24)

m = 4 +/- √(24) = 4 +/- 2√(6)

Then m, the slope of the line, may be 4 + 2√6 and 4 - 2√6

If YW bisects XYZ and mZXYW = 25°, then what is mZXYZ?​
Alisiya [41]

Answer:

50°

Step-by-step explanation:

Since, YW bisects angle XYZ.

\therefore m\angle XYZ =2\times m\angle XYW\\\therefore m\angle XYZ =2\times 25\degree \\\huge \purple {\boxed {\therefore m\angle XYZ =50\degree}}

2x+4y=16
x-7=-4y

4y=16-2x
<span>4y=16-2(-4y+7)
4y=16+8y-14
-4y=2
-4y/-4=2/-4
<u>y=-0,5</u>

2x=16-4(-0,5)
2x=16+2
