$2.50 divided by 5= 0.5
0.5x7= 3.5
Your answer is $3.50 per cake but since you need 7 you do, $3.50x7= 24.5
So the final answer is $24.50

To get the answer. you have to find the unit rate.
To find the unit rate, divide 2.50 by 5 which is 0.5 or 50 cents.
(You can check to see if you did this right by multiplying, so .5x5=2.5)
Then you multiply .5 by 7 which is 3.5, or $3.50.

F(x)-mx+ b, f(-2)=3 and f(4)=1 , what is the value of m and b
NeX [460]

Answer: m=\dfrac{-1}{3}, b=\dfrac{7}{3}

Step-by-step explanation:

Given

Function is  f(x)=mx+b

f(-2)=3

\therefore 3=m(-2)+b\\\Rightarrow b-2m=3\quad \ldots(i)

f(4)=1\\\therefore 1=4m+b\quad \ldots(ii)

from (i) and (ii) we get

m=\dfrac{-1}{3}, b=\dfrac{7}{3}
