Answer:
$4x
Step-by-step explanation:
According to the scenario, computation of the given data are s follows,
Cost of book = $x
Game cost = 3 × $x = $3x
So, we can calculate the total money spend by using following formula,
Total money spend = Cost of book + Game cost
By putting the value, we get
Total money spend = $x + $3x
= $4x
So, the total amount Danny spend is $4x.
What is an equation of the line that passes through the points (-2,-6) and (6,8)?
Answer:
y=7/4x–5/2
Step-by-step explanation:
You must find the slope first, let it be m
[tex]m = \frac{y2 - y1}{x2 - x1} \\ = \frac{8 - ( - 6)}{6 - ( - 2)} \\ = \frac{14}{8} \\ = \frac{7}{4} [/tex]
then insert tu the formula y=mx+c to find the c (c is the intercept of y axis) choose any point that you want. i use (6,8)
[tex]y = mx + c \\ 8 = \frac{7}{4} (6) + c \\ c = - \frac{5}{2} [/tex]
so the equation is
[tex]y = \frac{7}{4} x - \frac{5}{2} [/tex]

Find the circumference of a circle with a diameter of 400 cm. Use 3.14 for π.
A.
628 cm
B.
3.14 cm
C.
2512 cm
D.
1256 cm
Answer:
D. 1256 cm
Step-by-step explanation:
Divide the diameter by 2 to get the radius so 400/2 = 200
C = 2 π r = 2 · π · 200 = 1256.637

Step-by-step explanation:
I'm going to use the process of elimination to get rid of the equations. The equation for slope is y=mx+b with b being the y-intercept. As you can see the y-intercept in this graph is 4 which removes the third equation as a possible answer. The slope is moving from left to right in a downwards direction which means it is a negative slope. The only answer with a negative slope is b therfore it is your answer.

The three angles of a triangle create the extended ratio 2:2:5. What is the measure of the largest angle?
Answer:
100°
Step-by-step explanation:
The ratio of angles of the triangle is 2:2:5. We know that the angle sum property of the triangle is 180°. So that , let the ratio be 2x : 2x : 5x .
=> 2x + 2x + 5x = 180°
=> 9x = 180°
=> x = 180°/9
=> x = 20°
Here the largest ratio is 5x . Therefore the largest Angle is ,
=> Largest Angle = 5x
=> Largest Angle = 5 × 20°
=> Largest Angle = 100°
• Hence the largest Angle is 100°Solve the system of equations : y=2x-8 and y=-x-8

What is a Translation?
Answer:
The displacement of a figure or a shape from one place to another is called translation, which means a figure can be moved upward, downward, left, right, or anywhere in the coordinate system using translation. While translating, all the points will shift by the same number of units.

Step-by-step explanation:
Answer:
31
Step-by-step explanation:
Range = Largest number ( in terms of value ) - smallest number ( in terms of value )
The largest number of the set is 37 and the smallest number is 6
Range = 37 - 6
37 - 6 = 31
Hence, the range is 31

Consider the conic section C represented by the equation 9x2 – 25y2 = 225. Which of these is a characteristic of the graph of C? (A) Vertices at (3,0) (B) Vertices at (0, 5) (C) Asymptotes at y = + x (D) Asymptotes at y = x 3
Answer:
The only true statement is:
(B) Vertices at (0, 5)
Step-by-step explanation:
We have the equation:
9*x^2 - 25*y^2 = 225
The graph of this equation can be seen below.
In the graph we can see:
We have two vertices, one at (0, 5) and another at (0, - 5)
Then option B) "Vertices at (0, 5)" is true.
Also in the graph you can see that we have (kinda linear) asymptotes at:
y = x + 5
y = -x + 5
y = x - 5
y = -x - 5
The two options for the asymptotes are:
(C) Asymptotes at y = + x
(D) Asymptotes at y = x 3
So both of these are incorrect.

Find the axis of symmetry and the vertex of the graph of f (x) = x^2 - 16 + 55
Hi there!
»»————- ★ ————-««
I believe your answer is:
Vertex: (0, 39)
Axis of Symmetry: x = 0
»»————- ★ ————-««
Here’s why:
I have graphed the equation on a program. When graphed, the the lowest point lies on the point (0, 39). This makes (0, 39) the vertex.⸻⸻⸻⸻
The axis of symmetry is a vertical line that intercepts the vertex. The vertical line makes the parabola seem 'symmetrical'. The 'x' value of the vertex is usually the line of symmetry as well.⸻⸻⸻⸻
The 'x' value of the vertex is '0', so the axis of symmetry is [tex]x = 0[/tex].
⸻⸻⸻⸻
See the graph that I have attached.
⸻⸻⸻⸻
»»————- ★ ————-««
Hope this helps you. I apologize if it’s incorrect.
Answer:
For equation:
[tex]f(x)=x^2-16x+55[/tex]
Vertex: [tex](8,-9)[/tex]
Axis of symmetry, ([tex]x=8[/tex])
For equation,
[tex]f(x)=x^2-16+55[/tex]
Vertex:[tex](0,39)[/tex]
Axis of symmetry, ([tex]x=0[/tex])
Step-by-step explanation:
The x-coordinate of the vertex of a parabola indicates the line of symmetry of the parabola. Thus, to solve this problem, one must find the vertex of the parabola. This can be done through a process called completing the square.
Completing the square is a process that converts a quadratic equation in standard form into vertex form. The first step is to group the linear and quadratic terms. Then factor out the coefficient of the quadratic term. After doing so, add a term to make the group a perfect square trinomial, then balance the equation.
Possibility 1
If the given equation is the following,
[tex]f(x)=x^2-16x+55[/tex]
Group,
[tex]=(x^2-16x)+55[/tex]
There is no quadratic term, thus, complete the square,
[tex]=(x^2-16x+64)+55-64[/tex]
Simplify,
[tex]=(x-8)^2-9[/tex]
Vertex: [tex](8,-9)[/tex]
Axis of symmetry, ([tex]x=8[/tex])
Possibility 2
If the given equation is the following,
[tex]f(x)=x^2-16+55[/tex]
Combine like terms,
[tex]=x^2+39[/tex]
Put in vertex form,
[tex]=(x)^2+39[/tex]
Vertex:[tex](0,39)[/tex]
Axis of symmetry, ([tex]x=0[/tex])
