Answer:
A
Step-by-step explanation:
The recursive rule lets us find a term in the sequence from the previous term.
The sequence of dots is
4 , 16, 64
Thus multiplying the previous term by 4 gives the required term, thus
f(x) = f(x - 1) × 4 : f(1) = 4
so
f(2) = f(1) × 4 = 4 × 4 = 16 ← true
f(3) = f(2) × 4 = 16 × 4 = 64 ← true
A is the correct choice
Answer:
9/24
Step-by-step explanation:
3/8
24 ÷ 8 = 3
3 x 3 = 9
9/24
Check:
9/24 = 0.375
3/8 = 0.375
Answer:
y=4x+7
Step-by-step explanation:
4x+y=7
Isolate one of the variables
4x-4x+y=7+4x
y=7+4x
slope is 4 (Up 4, Right 1)
y-intercept is (0,7)
It is true that in a word problem, instead of calling it the slope, we call it the starting point instead.
Although the two terms are interchangeable, in presenting the mathematical question, we need to use the term starting point so as to refer to the place where the slope starts, and not the whole slope.
