y=2x-3 an x+y=3

subsitution

since y=2x-3, put (2x-3) wherever you see y

put taht in the other equation

x+y=3

x+(2x-3)=3

x+2x-3=3

3x-3=3

add 3 to both sides

3x=6

divide by 3

x=2

subsitute back

y=2x-3

y=2(3)-3

y=6-3

y=3


so the solution set in (x,y) form is (2,3)

If you rearrange the equation so w is the independent variable, then what is u?<br><br> -2u+6w=9
Serjik [45]

Answer:

u  = - ( 9-6w)/2

Step-by-step explanation:

to  evaluate for u in the expression -2u+6w=9 is simply to look for a way such that we would express u in terms of w and other variables.

solution

-2u+6w=9

-2u = 9 - 6w

divide both sides by the coefficient of u which is -2

-2u/u = 9 - 6w/-2

u  = - ( 9-6w)/2

therefore the value of u when rearranged in the equation -2u+6w=9 is evaluated to be equals to

u  = - ( 9-6w)/2

\sqrt[8]{48^4}  can be rewritten as 48^4 to the \frac{1}{8}  power:

(48^4)^ \frac{1}{8}

Now, applying exponent rules (multiply exponent inside parentheses by the one outside parentheses), we get:

(48^ \frac{1}{2})

This is equivalent to \sqrt{48}, so now, we just simplify:

\sqrt{48}=  \sqrt{16*3}= \sqrt{16}* \sqrt{3}=4 \sqrt{3}

So:

\sqrt[8]{48^4} =4 \sqrt{3}

Hey can you please help me posted picture of question
jenyasd209 [6]

The equation of parabola is x=ay^2. If a is positive and y^2 is always greater than zero or equal to zero, then x is also greater or equal to zero. This means that parabola is determined for non-negative x and for all real y.

Tha canonical equation of parabola is y^2=2px, where p>0. The branches of this parabola go up in positive y-direction. When you change x to y and y to x, then the branches of parabola go in positive x-direction, that is right.

Answer: correct choice is A.
