<h3>
Answer is -8</h3>
Work Shown:
y = -(2^x)
y = -(2^3) ... replace x with 3
y = -(2*2*2) ... expand out 2 cubed
y = -8
we are given

Firstly , we can distribute

now, we can combine like terms


now, we can solve for x
and we get
...........Answer
Answer: x=4 ; y=<u> -4</u>
3
Step-by-step explanation:
2x + y = -4
.(-3)
2x + 3y = 4
-6x-3y=12
<u>2x + 3y = 4</u>
4x=16
x= <u>16</u>
4
x=4
2x + 3y = 4
2.4+3y=4
8+3y=4
3y= -8+4
y=<u> -4</u>

Given that <span>Li
is making beaded necklaces for each necklace, she uses 27 spacers, plus
5 beads per inch of necklace length.
The equation to find how many
beads Li needs for each necklace can be obtained as follows:
A. The input variable is the number of inches of the necklace length (x).
B. The output variable is the number of beads Li needs for each necklace (y).
C. The required equation is given by
y = 5x</span>
Answer:
1
Step-by-step explanation:
can be expressed as
=
Similarly
can be expressed as
=
Numerator becomes:
