Anythig else you could tell us to help? :)
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>
Answer:
x = 15
Step-by-step explanation:
We want to solve for x in 3*(2x + 5) = 3x + 4x
First simplify.
3*(2x + 5) = 7x
Next, distribute the 3.
3*2x + 3*5 = 7x
6x + 15 = 7x
15 = 7x - 6x
15 = x
Answer: 450 minutes
Step-by-step explanation:
4 hours and 30 minutes equals 4.5 hours.
3+4.5=
7.5 hours
1 hour equals 60 minutes
Hence,
7.5*60=
450 minutes
<em>From the question,</em>
<em>Rohan</em><em> bought an almirah for =Rs.13600= cost </em><em>price</em>
<em>Transportation cost =Rs.400</em>
<em>The total cost price of almirah =Rs.(13600+400)</em>
<em>The total cost price of almirah =Rs.(13600+400)=Rs.14000</em>
<em>He sold it for =Rs.16800= selling </em><em>price</em>
<em>By comparing SP and CP=SP>CP, so there is a </em><em>gain</em>
<em>Gain=SP−CP</em>
<em>=16800−14000</em>
<em>=Rs.2800</em>
<em>Gain %={(gain/CP)×100}</em>
<em>={(2800/14000)×100}</em>
<em>={2800/140}</em>
<em>=20%</em>
