Answer:
C
Step-by-step explanation:
twenty four and nineteen twentieths
Answer:
D
Step-by-step explanation:
A. The domain of this function is infinite, since x can be any number.
B. To find the y intercept, you need to set x to 0. 7^x will become 1, and 6*1=6, so the y intercept is (0,6).
C. This function is not always decreasing. For instance, when x is positive, it exponenentially increases.
D. As I said before, the y intercept of the function is (0,6), meaning that this statement is correct.
Hope this helps!
I believe that the answer is B
X + y = 10
y = x + 2
so sub in x + 2 for y back into the first equation
x + y = 10
x + x + 2 = 10
2x + 2 = 10
2x = 10 - 2
2x = 8
x = 8/2
x = 4
y = x + 2
y = 4 + 2
y = 6
solution is : (4,6)
