Can anybody help me with this? it’s probably simple but i don’t understand it

snow_tiger [21]

Answer:

KL=33

Step-by-step explanation:

Since all three sides have the ( symbol it means that all the angles in the triangle are the same. In a triangle with all the angles congruent the side lengths are also congruent.

As such you can make an equation where one side length equals the other.

10x+3=3x+24

10x-3x=24-3

7x=21

x=3

then just substitute 3 for x

3(3)+24=KL

9+24=KL

33=KL

Also it took me forever to understand this concept, trust me it can easily get confusing. I hope this helps!

Write the equation for a parabola whose vertex is (-6,-1) and passes through (-12,17).

Hitman42 [59]

Answer:

$y=\frac{1}{2}(x+6)^2-1$

Step-by-step explanation:

<u>Equation of the Quadratic Function</u>

The vertex form of the quadratic function has the following equation:

$y=a(x-h)^2+k$

Where (h, k) is the vertex of the parabola that graphically represents the function, and a is a coefficient different from zero.

The vertex of the required equation is located at (-6,-1)

The parabola passes through (-12,17)

Substituting the coordinates of the vertex, the equation of the function is:

$y=a(x+6)^2-1$

The value of a will be determined by using the given point:

$17=a(-12+6)^2-1$

Operating:

$17=a(36)-1$

$36a=18\Rightarrow a=18/36=1/2$

Solving:

$a=1/2$

The equation of the parabola is:

$\boxed{y=\frac{1}{2}(x+6)^2-1}$
