Jackie has 54 fewer beads than Sally. If b stands for the number of beads Jackie has, write an
expression that represents the number of beads Sally has?
Answer:
b+54
Step-by-step explanation:
Since Jackie has 54 fewer beads than Sally, Sally has 54 more beads than Jackie. Since b is the number of beads that Jackie has, then Sally's beads would be 54 more than that thus it would be b+54.

Answer:
The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].
The graph of this function is presented in the attachment.
Step-by-step explanation:
The general equation of the circunferece is defined by the following formula:
[tex]x^{2}+y^{2}+A\cdot x + B\cdot y + C = 0[/tex] (1)
We can determine the value of the coefficients by knowing three distinct points: [tex](x_{1}, y_{1}) = (3,0)[/tex], [tex](x_{2},y_{2}) = (5,-2)[/tex], [tex](x_{3},y_{3}) = (1, -2)[/tex]
The system of linear equations is:
[tex]3\cdot A + C = -9[/tex] (2)
[tex]5\cdot A -2\cdot B + C = -29[/tex] (3)
[tex]A -2\cdot B + C = -5[/tex] (4)
The solution of this system is: [tex]A = -6[/tex], [tex]B = 4[/tex], [tex]C = 9[/tex].
The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].
The graph of this function is presented in the attachment.

What is the range of y = x 2 − 1 , given a domain of {–2, –1, 0, 1, 2}
The range of the function y = x² - 1 is {- 1, 0, 3}.
What is the domain and range of a function?Suppose we have an ordered pair (x, y) then the domain of the function is the set of values of x and the range is the set of values of y for which x is defined.
Given, A function y = x² - 1.
The set of domains is {- 2, - 1, 0, 1, 2}.
The set of co-domain is {3, 0, - 1, 0, 3}.
We know range ⊆ codomain.
Therefore, The range is {- 1, 0, 3}.
