1.Given the lines shown here, what are two possible equations for this system of equations
2.How many solutions does this system have?
Answers
Answer:
Two possible equations:
[tex]y = x + 1\\y = x - 5\\[/tex]
The system has 0 solution as parallel lines never cross each other.
Step-by-step explanation:
Considering the two lines are parallel, they both have the same slope.
let m be the slope of the two lines:
[tex]y = mx + y_{0}\\y=mx+y_{1}[/tex]
[tex]y_{0}, y_{1}[/tex] are the value on y axis where the two lines cross the axis.
Because the lines are parallel, there exists no point that lies on both lines, therefore the system has 0 solution.

Answers
I believe that it is 31.4, but please correct me if I'm wrong.
The required area of the sculpture that is shaped like a circle is [tex]78.5m^{2}[/tex].
Given that,
Jessie designed a sculpture that is shaped like a circle,
The circumference of the sculpture is 10π meters.
We have to determine,
Which measurement is closest to the area of the sculpture in square meters.
According to the question,
Circumference of the circle = [tex]2\pi r[/tex]
Where, circumference = [tex]10\pi[/tex]
Then,
[tex]10\pi =2\pi r \\\\r = \dfrac{10\pi }{2\pi }\\\\r = 5m[/tex]
Therefore,
Jessie designed a sculpture that is shaped like a circle.
Area of the circle = [tex]\pi r^{2}[/tex]
Where, r = 5m
Then,
Area of the circle is given by,
[tex]= \pi r ^{2}\\\\= 3.14 \times (5)^{2}\\\\= 3.14 \times 25\\\\= 78.5m^{2}[/tex]
Hence, The required area of the sculpture that is shaped like a circle is [tex]78.5m^{2}[/tex].

Y=x. Given A(7,-4), B(6,4), and C(-1,-5), what are the coordinates of the vertices of A’B’C for the reflection
Answers
Answer:
The coordinates of the vertices of A'B'C' is:
A'(-4, 7)B'(4, 6)C'(-5, -1)Step-by-step explanation:
Given the coordinates of the triangle
A(7,-4)B(6,4)C(-1,-5)Reflection in the line y=x
We know that the rule of reflection in the line is y = x is:
(x, y) → (y, x)
Thus,
The coordinates of the vertices of A'B'C' for the reflection in the y = x
(x, y) → (y, x)
A(7, -4) → A'(-4, 7)
B(6, 4) → B'(4, 6)
C(-1, -5) → C'(-5, -1)
Thus, the coordinates of the vertices of A'B'C' is:

Which costs the most per ounce, 60 oz. of peanut butter for $5.40, 28 oz. for $2.24, or 16 oz. for $1.76? Explain how you got your answer.
Answers
Answer:
28 oz. for $2.24 cost most per ounce
$12.5 per oz
Step-by-step explanation:
Find the cost per ounce by dividing the total oz by cost of the total oz
60 oz. of peanut butter for $5.40
Cost per the ounce = 60 oz / $5.40
= $11.11 per oz
28 oz. for $2.24
Cost of peanut butter per ounce = 28 oz / $2.24
= $12.5 per oz
16 oz. for $1.76?
Cost of peanut butter per ounce = 16 oz / $1.76
= $9.10 per oz
28 oz. for $2.24 cost most per ounce

If f(x) = x^3 + 13x^2 + 46 x + 48 and x + 8 is a factor of f(x) find all of the zeroes of f(x) algebraically
Answers
If x + 8 is a factor, we can factor it out from f(x).
f(x) = (x+8)(x²+5x+6)
= (x+8)(x+2)(x+3)
The zeroes of f(x) are -8, -2 and -3.

FunctionFunctions relates inputs to outputs. A function relates each value of a set with exactly one value of another sets.
Every element in the input must be related to some element in the output.
Same elements in x cannot be related to different elements in y.
