Find the slope of a line parallel to a line with a slope of 4/5
Answer:
slope = 4/5
Step-by-step explanation:
The question is asking us to find the slope of the line that's parallel to the line whose slope is 4/5.
Recall that parallel lines have equal slopes.
So the slope of the line that's parallel to the one with a slope of 4/5 is 4/5 too.
Therefore, slope = 4/5.

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

What is the distance between points (8,3) and (3, 1) on the coordinate plane?
OA. 3 units
OB. 21 units
OC.29 units
OD. 7 units
Answer:
√29
Step-by-step explanation:
You would use the distance formula in this case to solve the problem:
(8-3)^2+(1-3)^2=29
Now square root 29, leaving you with √29.
Answer:
5.39
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√(3 - 8)² + (1 - 3)²
√(-5)² + (-2)²
√25 + 4
√29
= 5.39

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.

Answer:
[tex]y = - \frac{7}{3} x + 4[/tex]
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.

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])

What is the difference between the definitions for ray and line segment?
Only the definition of ray relies on an understanding of two directions.
Only the definition of line segment relies on an understanding of line.
Only the definition of ray depends on an understanding of infinite.
Only the definition of line segment depends on an understanding of point.
Answer:
Only the definition of the line segment depends on an understanding of point.

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]
