Both lines pass through the point represented by the ordered pair.
You cannot tell whether an ordered pair is a solution of a system of linear equations by examining the graphs of the equations.
Just one of the lines passes through the point represented by the ordered pair.
Neither line passes through the point represented by the ordered pair.
Answer:
A.) Both lines pass through the point represented by the ordered pair
Step-by-step explanation:
Both lines pass through the point represented by the ordered pair.

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
An ordered pair is a solution of a system of linear equations by examining the graphs of the equations.
We know that;
An ordered pair is a solution of a system of linear equations when both the lines are passing through the same ordered pair.
Hence, We get the correct sentence is,
''Both lines pass through the point represented by the ordered pair.''

On what interval(s) of x does f have positive concavity?
On what interval(s) of x does f have negative concavity?
Answer:
Step-by-step explanation:
Concavity of a quadratic function is determined the leading coefficient.
If the leading coefficient is positive, graph will entirely concave upwards.
If the leading coefficient is negative, graph will concave downwards entirely.
So in the interval (-∞, ∞) function has the positive concavity.
There is no interval in which the given function has the negative concavity.

Please help me hurry
Answer:
The length of the house is 32 yards and the width is 16 yards and the area of the deck is 512 yards. I got my answer by multiplying the length and the width to get an answer of 512.
Step-by-step explanation:
You have to multiply 16 centimeters by 2 and multiply 8*2. Which is 32 and 16 and after you do that you multiply them 32*16=512
Pls pls help it is due todayyy:)))
Answer:
a dilation is different from a translation because it enlarges an image or shrink them instead of moving them. it's also different from rotation since it doesn't rotate but enlarge or shrink. it's way far from reflection because it enlarges or shrinks.
Answer: A diliation is a non rigid transformation, whereas reflections, transitions and rotations are rigid transformations. This means that dilations do not preserve the size of the shape.

For each function, select Steeper, Less steep, or Reflected over the x-axis to describe the differences between the graph of the function and the graph of f(x).
Select all answers that are correct.
Answer:
First, let's do some general definitions:
We start with:
f(x) = 3.5*x^3
A general equation of this form is:
g(x) = a*x^3
if:
IaI > 3.5 the function will be steeper.
IaI < 3.5 the function will be less steep.
a < 0, means that we have a reflection over the x-axis.
Then:
p(x) = 4.5*x^3
bassed on what we wrote above, this function is steeper than f(x)
q(x) = -x^3
This is less steep ( a = -1 in this case) and we also have a reflection over the x-axis.
r(x) = 3*x^3
In this case 3 < 3.5, this means that this will be lees steep than f(x)

Use the function f(x) to answer the questions:
f(x) = 2x2 − 5x + 3
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or a minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answer:
Step-by-step explanation:
Part A)
For equation f(x) = 2x² - 5x + 3, to find x intercepts let y=0 then solve x,
2x² - 5x + 3 = 0 -> (2x + 1)(x -3) = 0 , can find x - intercepts from here
x = ____ and ____
Part B)
To find if vertex is a max or min, compare to equation y = ax² + bx +c
if a > 0 then parabola opens up and vertex is a minimum.
if a < 0 then parabola opens down and vertex is a maximum,
thus vertex is a minimum in this problem
to solve vertex set x = -b / 2a = 5 / 2(2) = 5/4
solve for y value
.... vertex is then at point ( 5/4 , y value found)
Part C)
Can plot the intercepts and vertex points

The value of the surface area of the rectangular prism is,
SA = 700 units²
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
In a rectangular prism,
Length (l) = 14
Width (w) = 12
Height (h) = 7
We know that;
The surface area of a rectangular prism is given by:
SA = 2 (lh +wh + lw ) Square units.
Hence, We get;
SA = 2 (14 x 7 + 12 x 7 + 14 x 12
SA = 2 (98 + 84 + 168)
SA = 2 x 350
SA = 700 units²
Thus, The value of the surface area of the rectangular prism is,
SA = 700 units²
