How is an equation like an expression? How is it different?

morpeh [17]

Answer:

See explanation.

Step-by-step explanation:

An expression is a set of terms that are combined using addition, subtraction, multiplication, or division. The following are examples of expressions:

$2x-1$

$5y+8$

$2$

Note: expressions do not equal anything.

In contrast, equations are expressions that equal at least one term. The following are examples of equations:

$2y-4=26$

$4x-4=0$

$x=10$

$y=x+2$

Note: equations do equal a term, as shown in the examples.

We'll have to repeatedly square both sides of the equation, in order to get rid of the square roots. Squaring a first time yields

$19+\sqrt{30+\sqrt{32+x}}=25$

Move the 19 to the right hand side:

$\sqrt{30+\sqrt{32+x}}=6$

And square again:

$30+\sqrt{32+x}=36 \iff \sqrt{32+x}=6$

Square one last time:

$32+x=36 \iff x=36-32=4$

Let's check the solutions: all these squaring might have created external solutions:

$\sqrt{19+\sqrt{30+\sqrt{32+4}}}=\sqrt{19+\sqrt{30+6}}=\sqrt{19+6}=\sqrt{25}=5$

So, $x=4$ is a feasible solution.

What are the coordinates of the image of point T(2,4) over the transformation D(1/2,R), where R(6,-2) is the center. X= ? Y= ?

forsale [732]

Answer:

T'(4, 1)

Step-by-step explanation:

The dilation transformation around a center not the origin is ...

T' = k(T -R) +R . . . . for dilation factor k and center R

This can be simplified to ...

T' = 1/2T -1/2R +R = 1/2T +1/2R = (T +R)/2

Using the given point values, we find the image point to be ...

T' = ((2, 4) +(6, -2))/2 = (8, 2)/2 = (4, 1)

The image point is T'(4, 1).
