Gven the following table, find the rate of change between f(-4) and f(0)
x -4 -2 0 2 4
f(x) -2 -1 0 1 2
A. -2
B. 2
C. -1/2
D. 1/2
we know that
the rate of change is equal to
(f(b)-f(a))/(b-a)
f(b)=f(0)
f(a)=f(-4)
b=0
a=-4
(f(0)-f(-4))/(0+4)
we have that
f(0)=0
f(-4)=-2
substitute
(0+2)/4
2/4
1/2
therefore
<h2>the answer is the option D</h2>
C= 43(x-3)+128
the cost is 43 dollars per foot of the perimeter. It is unknown so we will use x for feet. we do not include the 3 feet of the fence so we have 43(x-3) so we do not count the length of the fence twice. The gate will be required and will cost 128.
Answer:
4/9 and 8/9
Step-by-step explanation: you have to have a common denominator so you take 3 and 9 and find what they both go into and that number is 9 so take 2/3 and times the top and bottom by 3 to get 6/9 and 2/9 by 1 to get 2/9 once you have those subtract them to get 4/9 and that's your first answer then take them and add so you get 8/9 which is your second answer
Answer:
a = -2
Step-by-step explanation:
The first equation can be rewritten in slope-intercept form:
5y = -10x +90
y = -2x +18
The value a=-2 will make the second line identical to the first.
