Y = 143°

to start off, if we look closely we will see that 37 + y = 180 because of the straight line that they form if added together. so, we can subtract 37 from both sides to get, y = 143. if you want to test it out with 3x + 1, you can simply find x by equaling this to 37 because they are each others’ vertex. so, 3x + 1 = 37 and simplified, x = 12.

3(12) + 1 + 143 does in fact equal 180.

so, y = 143° :)

A teacher had $57. 72 I’m his Checking’s account .He made a deposit of $209. 54 .Then he wrote a check for $72.00 and another ch

Brums [2.3K]

$57.27 + 209.54 = 267.26$
$72.00 + 27.50 = 99.50$
$267.26 - 99.50 = 167.76$
167.76 is the new balance in the checking account.

Simplify.<br> (WILL GIVE BRAINLIEST)

Novosadov [1.4K]

Answer:

$\frac{\sqrt{x} }{2x}$

Step-by-step explanation:

Rationalize the denominator first (keep in mind we are NOT solving this because there is no equals sign here. We are merely simplifying.)

$\frac{\sqrt{5x} }{x\sqrt{20} } *\frac{\sqrt{20} }{\sqrt{20} } =\frac{\sqrt{100x} }{20x}$

Now simplify by taking the square root of 100 to get:

$\frac{10\sqrt{x} }{20x}$

Divide numerator and denomiator by 10 to get:

$\frac{\sqrt{x} }{2x}$

What is the domain of the function y=cube root of x

All real numbers. in interval notation, that's (<span><span>−∞</span>, ∞</span><span>). there isn't a value you could insert for "x" that would give you an error.</span>
