Which of the following functions has its only zero at x=-4
f(x)= |x|+4
f(x)= |x|-4
f(x)= |x+4|
f(x)= |x-4|

f(x)=|x|-4

Step-by-step explanation:

Plug the equations into a TI-84 calculator

go to 2nd graph

look at the table and find -4 on the x side.

The correct equation will show 0

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
