Find the equation of the quadratic function with vertex (-2,18) passing through (-5,0)?
Sliva [168]

Answer:

y-18=-2(x+2)^2

Step-by-step explanation:

Equation of the Quadratic Function

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

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

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

It's been given the vertex of the parabola as (-2,18):

y-18=a(x+2)^2

Now substitute the point (-5,0) and find the value of a:

0-18=a(-5+2)^2

Operating:

-18=a(-3)^2

-18=9a

Solving for a:

a = -18 / 9

a = -2

Thus, the equation of the quadratic function is:

\mathbf{y-18=-2(x+2)^2}

Combine the like terms to create an equivalent expression: <br> 2s+(−4s)=?
Sergeeva-Olga [200]

Answer:

2s+\left(-4s\right)=-2s is the equivalent expression as 2s+\left(-4s\right) is equal to -2s.

Step-by-step explanation:

Considering the expression

2s+\left(-4s\right)

As we know that

  • Like terms are said to be the terms which hold the same variables raised to the same power.
  • For example, 3x and 2x are like terms as they contain the same variable x raised to the same power.

Lets solve the expression

2s+\left(-4s\right)

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a

2s-4s

\mathrm{Add\:similar\:terms:}\:2s-4s=-2s

-2s

Therefore,

2s+\left(-4s\right)=-2s is the equivalent expression as 2s+\left(-4s\right) is equal to -2s.

Keywords: equivalent expression, like terms
