Answer:
I'll answer one question
Step-by-step explanation:
a. x >= -4. This reads, the domain is greater than and equal to negative four to infinity.
Answer:
it seems like the first term is -64, so lets write the formula accordingly:
a_n = a1(r)^(n-1)
where 'n' is the number of terms
a1 is the first term of the sequence
'r' is the ratio
the ratio is because -64 * = 16 and so on...
the explicit formula is :
=
Step-by-step explanation:
Y=-4x+3
2x+3y=19
2x+3(-4x+3)=19
2x-12x+9=19
-10x=10
X=-1
y=-4*(-1)+3=4+3=7
x=-1 y=7
The temperature at midnight would be -14*F. Subtract 10 from -4 and you get -14*F
