Answer:

It depends on how you interpret the statement.

( x * -7 ) + ( 5 - 2 )

x * ( -7 + 5 ) - 2

Step-by-step explanation:

"a number times negative seven added to five equals two"

Let's set x as our number.

So the statement would translate to:

x * -7 + 5 - 2

To simplify, we might try to organize things by adding some parentheses. But that's when things start to get a little.....dicey.

Depending on how you interpret the original statement, both (x*-7)+5-2 and x*(-7+5)-2 can satisfy the statement.

Herein lies our problem. Which of the two expressions is correct?

Well.....both of them, actually. It just depends on how you're interpreting the statement and what options you have available.

If you can only pick one, but all of the expressions are possible options, then you're kind of stuck.

1/3 + 1/4 and the the sinplest form
Verizon [17]
The least common multiple between 3 and 4 is 12, so we can use this fact to rewrite both 1/3 and 1/4 in 12ths:

\big( \frac{1}{3}\times \frac{4}{4}\big) + \big(\frac{1}{4}\times \frac{3}{3}\big)=\\ = \frac{4}{12}+ \frac{3}{12}\\\\ = \frac{7}{12}

We're left with an answer of 7/12, which can't be reduced.

Can someone please help me please?
ladessa [460]

Answer:

B

Step-by-step explanation:

F(x) is just a negative vertical shift downwards, so when you have a downwards shift the number of units down is placed right after the x outside of the parenthesis. In this case, there was a shift of -4, so it would be -x^2 - 4.
