Ax+b=y
put the both values the left one is x and the right one is y
(1,3)=> a+b=3
(2,1)=> 2a+b=1
subtract both of the equations you will get -a=2
so a=-2 and put a in any of the equation you will get b is 5 so the equation is -2x+5=y
the slope is the x’s number so it’s -2
F(x)=x^2+2x-10
f(-2)=4-4-10
f(-2)=-10
the answer is A) or -10
Answer:
b = 64/a³
Step-by-step explanation:
Using the given information, we can only find a relation between a and b. We cannot find any specific value for b.
Since a varies inversely as the cube root of b, we have ...
a = k/∛b
Multiplying by ∛b lets us find the value of k:
k = a·∛b = 1·∛64 = 4
Taking the cube of this equation gives ...
64 = a³b
b = 64/a³ . . . . . divide by a³
The value of b is ...
b = 64/a³
