Add. (5x - 2y + 7) + (3x + y - 8)

Schach [20]

Answer:

$=8x-y-1$

Step-by-step explanation:

So we have the expression:

$(5x-2y+7)+(3x+y-8)$

Combine like terms:

$=(5x+3x)+(-2y+y)+(7-8)$

Add:

$=8x-y-1$

And we're done!

Which shows all the values of x that make the rational expression undefined? x = 6 x = 7 x = –6 or x = 6 x = –7 or x = 7

n200080 [17]

<h2>Explanation:</h2>

The rational expression is given by:

$E=\frac{2x^2-72}{5x^2-245} \\ \\ Factor \ out: \\ \\ E=\frac{2(x^2-36)}{5(x^2-49)} \\ \\ E=\frac{2(x-6)(x+36)}{5(x-7)(x+7)} : \ \ \ \ a^2-b^2=(a-b)(a+b)$

The denominator can't be zero, therefore:

$(x-7)(x+7)\neq 0 \\ \\ \\ Thus: \\ \\ \boxed{x\neq 7 \ and x \neq -7}$

Finally,<em> the values of x that make the rational expression undefined are </em>

What is the center and radius of the following circle (x - 5) ^ 2 + (y + 2) ^ 2 = 16

murzikaleks [220]

Answer:

Step-by-step explanation:

if center=(h,k)

radius=r

eq. of circle is (x-h)^2+(y-k)^2=r^2

given eq. is (x-5)^2+(y+2)^2=16=4^2

comparing

center =(5,-2)

radius r=4
