Remember that a quadratic equation is a parabola. The equation is of the type y = Ax^2 + Bx + C


A linear equation is a straight line. The equation is of the type y = MX + N


The soluction of that system is Ax^2 + Bx + C = MX + N

=> Ax^2 + (B-M)x + (C-N) = 0


That is a quadratic equation.


A quadratic equation may have 0, 1 or 2 real solutions. Those are all the possibilitis.


So you must select 0, 1 and 2.


You can also get to that conclusion if you draw a parabola and figure out now many point of it you can intersect with a straight line.


You will realize that depending of the straight line position it can intersect the parabola in none point, or one point or two points.

Use the Distributive Property to expand this expression.<br><br> z(–6.4 – 3.5x)
dedylja [7]

Answer:

z\left(-6.4\:-3.5x\right)=-6.4z-3.5zx

Hence, Option 'C' is true.

Step-by-step explanation:

Given the expression

z\left(-6.4\:-3.5x\right)

Apply distributive law:   a\left(b-c\right)=ab-ac

Here:  a=z,\:b=-6.4,\:c=3.5x

so the expression becomes

z\left(-6.4\:-3.5x\right)=z\left(-6.4\right)-z\cdot \:\:3.5x

                         =-6.4z-3.5zx                 ∵  +\left(-a\right)=-a

Therefore,

z\left(-6.4\:-3.5x\right)=-6.4z-3.5zx

Hence, option 'C' is true.

Find each missing measure.
Anni [7]

Answer:

m∠E= 37°

m∠F=37°

Step-by-step explanation:

Total angle value: 180°

180-106=74

The lengths are the same, so we can determine that the angles E and F are the same. So we divide 74 by 2

74/2= 37

m∠E= 37°

m∠F=37°

Hope this helps! Have a nice day :)
