For choice A, we can rearrange the equation to 38x=0, so it has exactly one solution, x=0.

For choice B, we rearrange the equation to 38x=36, so this too has exactly one solution, x=\frac{36}{38}=\frac{18}{19}.

Rearranging the equation in choice C by eliminating the x terms gives us the false equality -18=18, so this equation has no solutions.

Eliminating x in the equation in choice D gives the equality 18=18, which is always true, so this equation has infinitely many solutions.

Thus, we conclude that choices A and B work.

Use the distributive property and multiply everything in the parentheses by 14.
Leaving you with.. (70 - 3.5 x 350) + 2 / 4 x 1.
Then reduce the parentheses. 
Leaving you with.. ( -1155) + 2 / 4 x 1
Then divide 2 by four.
Leaving you with.. (-1155) + .5

True or false the values [x] and [-x] are always equal
RoseWind [281]

Answer:

If you mean |x| and |-x| yes they are equal.

Step-by-step explanation:

Brackets do not exactly specify the meaning of absolute value.

On most keyboards, above the enter button on the main keyboard part (not the keypad one) there is a back slash symbol \ and if you hold shift, there might be another symbol | which more accurately represents absolute value,

If you aren't talking about the absolute value, then no.

Triangle QST  is similar to triangle PQR

We are given that measure of angle SRP is 90°

Q is the point of the hypotenuse SP

Segment QR is perpendicular to PS and T is a point outside the triangle on the left of s

We need to find which triangle is similar to triangle PQR

So,

Using Angle - Angle - Angle Criterion We can say that

m∠PQR = m∠SQR  (AAA similarity)

m∠SQR=m∠SQT (AAA similarity)

Where m∠Q =90°  in ΔQST and PQR

Therefore ΔQST is similar to ΔPQR
