The zeros of <span>y = 3x^2+3x means to solve for the values of x when y = 0
</span> <span>y = 3x²+ 3x =0
</span>
<span>y = 3x²+3x = 0
</span>
<span>3x²+3x = 0 Factorize
3x(x + 1) = 0
3x = 0, or (x + 1) = 0
From 3x = 0, x = 0/3 =0
From (x + 1) = 0, x = 0 -1 = -1.
Therefore the zeros are 0 and -1.

Answer:
Number of photos = 3 * minutes
Step-by-step explanation:
Answer:

Step-by-step explanation:
we are given
- Amplitude:7
- Period:9π
- Phrase shift:¼
remember that,

where A is the Amplitude
B is the Period
C is the Phase shift
D is the vertical shift
note that, since D isn't given we'll take it 0
altogether substitute:

hence,
our equation is

and we are done!
Im not to sure bc there isnt an age with the brother so whatever 6 plus b is
