how many solutions does the nonlinear system of equations graphed below have
a. one
b. four
c. zero
d. two
Answers
Answer:
The nonlinear system of equations has 4 solutions ⇒ B
Step-by-step explanation:
The number of solutions of a system of equations equal to the number of points of intersection of the graphs of the equations of the system
Let us use this note to solve the question
From the given figure
∵ The nonlinear system of equations represented by two curves and a circle
∵ Each curve intersects the circle into two points
∴ The number of the points of intersection is 4
→ By using the note above
∵ The number of intersection points equal to the number of solutions
∴ The number of solutions is 4
∴ The nonlinear system of equations has 4 solutions

Eric's father Works two part-time jobs one in the morning and one in the afternoon and works a total of 40 hours each five day workweek if your schedule is the same each day and he works 3 hours each morning how many hours does Eric's father work each afternoon
Answers
Answer:
8
Step-by-step explanation:
because 40 devided by 5 equals 8 so thats how many hours in the afternoon
40 - 15 = 25
He works 25 hours in the afternoon every week.
25 / 5 = 5
So his father works 5 hours every after noon 5 days out of the week
film processing costs $4.95, plus $0.35 for each picture printed. Milan paid $11.95 for processing and printing. How many pictures did he have printed?
Answers
Answer:
20 pictures.
Step-by-step explanation:
In this question, we need to find out how many pictures Milan printed.
We know that the film processing costed $4.95 and each picture that was printed costed $0.35.
Lets turn this into an equation with x representing the amount of pictures:
y = 0.35x+ 4.95
Now we need to solve the equation. We can do this by plugging in our known cost, 11.95, into "y".
Solve:
11.95 = 0.35x + 4.95
Subtract 4.95 from both sides.
7 = 0.35x
Divide both sides by 0.35
20 = x
Milan printed 20 pictures.
Question 7 of 25 Which of the binomials below is a factor of this trinomial? x - 6x-16 O A. X-1 O B. X-8 OC. X-16 O D. x-2
Answers
Answer:
(x-8) is the factor.
Step-by-step explanation:
The given trinomial is [tex]x^{2}-6x-16[/tex].
We need to find the factor of this trinomial.
[tex]x^{2}-6x-16=x^2-8x+2x-16\\\\=x(x-8)+2(x-8)\\\\=(x+2)(x-8)[/tex]
The factors of [tex]x^{2}-6x-16[/tex] is (x-2) and (x-8).
So, the factor of [tex]x^{2}-6x-16[/tex] is (x-8). Hence, the correct option is (B).

Graphs:The set of ordered pairings (display style [tex](x,y)[/tex]) of a function (display style [tex]f(x)=y[/tex]) in mathematics is known as the graph of that function. These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the typical case where "display style [tex]x[/tex]" and "display style [tex]f(x)[/tex]" are real values.Graph equations:Equations with graphs as the unknowns are known as graph equations in graph theory. The concept of isomorphism is one of the key issues in graph theory. Different graph equations may be used to express the aforementioned graphs.Therefore, the correct equation for the blue graph is [tex]g(x)=(x-4)^{2}[/tex].

[tex] \Large{\boxed{\sf n = 8}} [/tex]

Explanation:The perimeter of a rectangle is given by the following formula:
[tex] \Large{\sf P = 2L + 2W } [/tex]
Where:
P is the perimeter of the rectangle.L is its length.W is its width.[tex] \\ [/tex]
[tex] \Large{\boxed{\sf Given \text{:} } \begin{cases} \sf L &=\sf 3n - 9 \\ \sf W &=\sf n + 5 \\ \end{cases} } [/tex]
[tex] \\ [/tex]
Substitute these values into our formula:
[tex] \sf P = 2(3n - 9) + 2(n + 5) [/tex]
[tex] \\ [/tex]
Expand the expression of the perimeter using the following distributive property.
[tex]\green{\begin{gathered}\begin{gathered} \\ \boxed { \begin{array}{c c} \\ \blue{ \sf\boxed{ \sf Distributive \: property \text{ : } }} \\ \\ \sf\star \: \red{ \large{ a (b + c) = ab + ac }} \end{array}}\\\end{gathered} \end{gathered}}[/tex]
[tex] \\ [/tex]
We get:
[tex] \sf P = 2(3n) + 2(-9) + 2n + 2(5) \\ \\ \sf P = 6n - 18 + 2n + 10 \\ \\ \boxed{\sf P = 8n - 8 } [/tex]
[tex] \\ [/tex]
Since the perimeter is equal to 56, the value of n satisfies the following equality:
[tex] \sf 8n - 8 = 56 [/tex]
[tex] \\ [/tex]
To solve this equation, let's add 8 to both sides:
[tex] \sf 8n - 8 + 8 = 56 + 8 \\ \\ \sf 8n = 64 [/tex]
[tex] \\ [/tex]
Now, divide both sides of the equation by 8:
[tex] \sf \dfrac{8n}{8} = \dfrac{64}{8} \\ \\ \\ \boxed{\boxed{\sf n = 8}} [/tex]

Answers
9514 1404 393
Answer:
up: (-3, 5); down: (-3, -3); right: (1, -2); left: (-6, -2)
Step-by-step explanation:
As you know, the coordinates of a given point tell you the distance ...
(right, up)
So, a displacement 7 units up adds 7 to the second coordinate value:
A(-3, -2) ⇒ A'(-3, -2+7) = A'(-3, 5) . . . . 7 units up
Likewise, 1 unit down subtracts 1 unit from the second coordinate value:
A(-3, -2) ⇒ A'(-3, -3) . . . . 1 unit down
__
Similarly, left-right changes affect only the first coordinate. Displacements right are added; displacements left are subtracted.
A(-3, -2) ⇒ A'(-3+4, -2) = A'(1, -2) . . . . 4 units right
A(-3, -2) ⇒ A'(-6, -2) . . . . 3 units left
Suppose m is the line with equation x=-5, line n is the equation y=1
Answers
Here is the complete question:
suppose m is the line with equation x=-5, line n is the line with equation y=1, line g is the line with equation y=x, and line h is the line with equation y=-2. Given A(9,-3), B(6,4), and C(-1,-5), what are the coordinates of the vertices of △A′B′C′ for each reflection?
1. Rx-axis
2. Ry-axis
Answer with step-by-step explanation:
1. When you get the reflecting coordinates along x-axis, the signs of the y coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:
A(9, 3), B(6, -4), and C(-1, 5).
2. When you get the reflecting coordinates along y-axis, the signs of the x coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:
A(-9, -3), B(-6, 4), and C(1, -5).
