What is 2x(y+5)=2.5y<br> What is 2x(y+5)=2.5y
White raven [17]

Answer:

simplify: 2.5 =(y+5)

reorder the terms: 2.5y=(5+y)

remove the parenthesis: 2.5y=5+y

solving: 2.5y=5+y

move all terms containing y to the left, all other terms to the right.

add -1y to each side of the equation

2.5y+-1y=5+y+-1y

combine like terms 2.5y+-1y=1.5y

1.5y=5+y+-1y

combine like terms: y+-1y=0

1.5y=5+0

1.5y=5

divide each side by 1.5

y=3.333333333

simplifying

y=3.333333333

What is the range of the function y = x 2?
Leno4ka [110]

Answer:

\mathrm{Range\:of\:}x^2:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}

The graph is also attached below.

Step-by-step explanation:

Given the function

y=x^2

  • We know that the range of a function is the set of values of the dependent variable for which a function is defined.

\mathrm{For\:a\:parabola}\:ax^2+bx+c\:\mathrm{with\:Vertex}\:\left(x_v,\:y_v\right)

\mathrm{If}\:a

\mathrm{If}\:a>0\:\mathrm{the\:range\:is}\:f\left(x\right)\ge \:y_v

a=1,\:\mathrm{Vertex}\:\left(x_v,\:y_v\right)=\left(0,\:0\right)

f\left(x\right)\ge \:0

Thus,

\mathrm{Range\:of\:}x^2:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}

The graph is also attached below.
