Answer:
b
Step-by-step explanation:
If 12a + 3b = 1 and 7b – 2a = 9, what is the average (arithmetic mean) of a and b ? Add 12a+3b= 1 and 7b-2a=9, then we will get 10a+10b=10 which results 10(a+b)=10. Thus a+b=1. Therefore, the answer is B
Whole number, real number, integer, and irrational.
Y=-2x+5
The standard form is y=mx+b, since m is the slope you would put -2 in substitute for it and since (0,5) has a zero as the x and a number as the y that gives you the b which is the y-intercept.

Step-by-step explanation:
190 x 4.00 + 60 x 2.5 = 910
Answer:
exponential: y = 2^(-x)
Step-by-step explanation:
The y-differences are not constant, and the x-y products are not constant. For each increase in x, y is divided by 2, so this is a geometric sequence that can be described by an exponential model. The common factor is 1/2.
A simple way to write the model for this is ...
y = 2^(-x)
