Answer:
5
Step-by-step explanation:
Plug in x = 2 into the equation 2x + 1
2x + 1
2 * 2 + 1
4 + 1
5
The answer is 4/8 because half of 16 is 8 and half of 8 is 4, therefore they are equivalent
<span>x=y+2
2y=x-1
substitute </span>x=y+2 into 2y=x-1
2y=x-1
2y=y+2 -1
2y - y = 1
y = 1
<span>x=y+2
</span><span>x=1+2
x=3
answer
x = 3 and y = 1</span>
Answer:
36.875 inches
Step-by-step explanation:
Let [a, b] = the interval
The average rate of change can be found by using [f(b) - f(a)]/(b - a).
Let a = 1 and b = 5.
Let R = rate of change
17- x^2
R = [17 - 5^2] - [17 - 1^2]/(5 - 1)
R = [17 - 25] -[17 - 1]/4
R = [(-8) - (16)]/4
R = (-24)/4
R = -6
Done.
