Tell which equation you would choose to solve for one of the variables when solving the system by substitution. 2x+3y=5 4x-y=3

PtichkaEL [24]

i would solve 4x-y =3 for y because the coefficient for y is 1

subtract 4x from each side

-y = -4x+3

divide by -1

y = 4x-3

Answer:

12.5 pi or 39.26990

Step-by-step explanation:

First we can find the radius, which is half the diameter, 5 feet. To find the area of a semi-circle we would find the area of the circle and then divide by 2:

$\frac{\pi r^2}{2}$

We can substitute what we have:

$\frac{25\pi }{2}$

This gives us:

12.5 pi or 39.26990(Not sure what format you need it in)

Which of the following are solutions to | x-1|= 5x + 2 ? Check all that apply.

agasfer [191]

By definition of absolute value, if $x-1\ge0$ , then $|x-1|=x-1$ , so

$|x-1|=5x+2\implies x-1=5x+2\implies4x=-3\implies x=-\dfrac34$

On the other hand, if $x-1$ , then $|x-1|=-(x-1)=1-x$ , and

$|x-1|=5x+2\implies1-x=5x+2\implies6x=-1\implies x=-\dfrac16$
