Answer:
only the first option is correct
Step-by-step explanation:
Let the bank balance be b
b is less than $20;
This mean ;
b < $20
So let us select the correct options;
a. This is correct
As we can see, b represents the bank balance which is the variable in the inequality
b. This is incorrect
The inequality symbol is <
c. This is incorrect
The inequality symbol needed is not 20
Given :
Set of x-intercepts {-3,1,7},
point through which it passes (-2,54)
Now,
Step 1: Substitute value of x intercepts in equation,
, we get,

... equation (1)
Step 2: substitute x an y with the point through which it passes,


∴ 
Step 3: Now, substituting value of a in equation (1), we have

(Requited cubic equation)
This doesn't make sense provide more info? :)
Five over there to the power of negative two is
Three squared over five squared
Which is 9 over 25
Answer:
No solution.
Step-by-step explanation:
Given

Find all possible solutions
If
, then the triangle is right-angled and the hypotenuse is at b
Given that 
This implies that a > b
In a right-angled triangle, the hypotenuse (side b) is the longest.
Since this is not true for the given sides, then the triangle has no solution.
