Create a table of data for two different linear functions. The table should use the same values of x for both functions. Based on your table, will the graphs of these two functions intersect? Explain your answer
The following data table for two distinct linear functions utilizing identical x values for both functions is displayed:
\(\begin{tabular}{|c|c|c|}$\mathrm{x}$ & $\mathrm{y}=2 \mathrm{x}+7$ & $\mathrm{y}=-\mathrm{x}+4$ \\$-3$ & $2(-3)+7=-6+7=1$ & $-(-3)+4=3+4=7$ \\$-2$ & $2(-2)+7=-4+7=3$ & $-(-2)+4=2+4=6$ \\$-1$ & $2(-1)+7=-2+7=5$ & $-(-1)+4=1+4=5$ \\0 & $2(0)+7=0+7=7$ & $-(0)+4=0+4=4$ \\1 & $2(1)+7=2+7=9$ & $-(1)+4=-1+4=3$ \\2 & $2(2)+7=4+7=11$ & $-(2)+4=-2+4=2$ \\3 & $2(3)+7=6+7=13$ & $-(3)+4=-3+4=1$\end{tabular}\)
The table demonstrates that the function y = 2x + 7 and the function y = -x + 4 both have values of 5 for x = -1.
As a result, the two functions' graphs will intersect at (1, 5)
First of all, we create 2 LINEAR function, i created the function f(x)=2x+5 and the function h(x)=3x+2, both are linear(without a quadratic term). Then
Choose a group of x values before creating the table. Add each x value from the left side column to the equation. To find the y value, evaluate the equation (middle column). Since the table of values really only contains x and y pairs, you can choose to omit the middle column from your table as an optional step.
you replace the x for a number:
Table 1 (F(X)=2X+5) Table 2 (H(X)=3X+2)
X=1----->Y=2+5=7 X=1------>Y=3·1+2=5
X=2---->Y=2·2+5=9 X=2----->Y=3·2+2=8
X=3---->Y=3·3+5=11 X=3----->Y=3·3+2=11
With both tables of data we can see that in the X=3/Y=11 point this two linear functions will intersect so the answer is that the two functions will intersect at (3,11)----->(X,Y)

Write the equation of this line in slope intercept form.
An equation of this line in slope intercept form is y = -1/6(x) - 5.
How to determine an equation of this line?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is represented by this mathematical expression;
y = mx + c
Where:
m represent the gradient, slope, or rate of change.x and y represent the data points.c represent the vertical intercept.First of all, we would determine the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (-5 - 0)/(0 - (-30)
Slope (m) = -5/30
Slope (m) = -1/6
At data point (0, -5), a linear equation in slope-intercept form for this line can be calculated as follows:
y = mx + c
y = -1/6(x) + (-5)
y = -1/6(x) - 5

A function and its inverse are shown on the same graph. Which statement describes the relationship between the function and its inverse?
Answer:
D should be right
Step-by-step explanation:
do the points (1, 1, 3), (2, 0, 1), (3, 1, 0), and (0, −4, 2) lie in a single plane?
The points (1, 1, 3), (2, 0, 1), (3, 1, 0), and (0, −4, 2) do not lie in a single plane.
To determine if the points (1, 1, 3), (2, 0, 1), (3, 1, 0), and (0, −4, 2) lie in a single plane, we can use 3d geometry.
First, we can find two vectors that lie on the plane using any three of the given points.
For example, we can use the vectors formed by (1, 1, 3) to (2, 0, 1) and (1, 1, 3) to (3, 1, 0):
v₁ = <2-1, 0-1, 1-3> = <1, -1, -2>
v₂ = <3-1, 1-1, 0-3> = <2, 0, -3>
Next, we can take the cross product of these vectors to find the normal vector of the plane:
n = v₁ x v₂ = <3, 7, 2>
Finally, we can check if the fourth point (0, -4, 2) lies on this plane by taking the dot product of the normal vector and a vector from the fourth point to any of the previous points:
n · (0-1, -4-1, 2-3) = -8
Since the dot product is not zero, the fourth point does not lie on the same plane as the first three points.
Therefore, the points (1, 1, 3), (2, 0, 1), (3, 1, 0), and (0, −4, 2) do not lie in a single plane.

Find the angle between vector bold lower u equals 3 bold lower I plus start root 3 end root bold lower j and vector bold lower v equals negative 2 bold lower I minus 5 bold lower j to the nearest degree. A. 82° B. 38° C. 142° D. 98°
Answer:
C. 142°
Step-by-step explanation:
You want the angle between vectors u=3i+√3j and v=-2i-5j.
AngleThere are a number of ways the angle between the vectors can be found. For example, the dot-product relation can give you the cosine of the angle:
u•v = |u|·|v|·cos(θ) . . . . . . where θ is the angle of interest
You can find the angles of the vectors individually, and subtract those:
u = |u|∠α
v = |v|∠β
θ = α - β
When the vectors are expressed as complex numbers, the angle between them is the angle of their quotient:
\(\dfrac{\vec{u}}{\vec{v}}=\dfrac{|\vec{u}|\angle\alpha}{|\vec{v}|\angle\beta}=\dfrac{|\vec{u}|}{|\vec{v}|}\angle(\alpha-\beta)=\dfrac{|\vec{u}|}{|\vec{v}|}\angle\theta\)
This method is used in the calculation shown in the first attachment. The angle between u and v is about 142°.
A graphing program can draw the vectors and measure the angle between them. This is shown in the second attachment.
__
Additional comment
The approach using the quotient of the vectors written as complex numbers is simply computed using a calculator with appropriate complex number functions. There doesn't seem to be any 3D equivalent.
The dot-product relation will work with 3D vectors as well as 2D vectors.

Your travel guide contains a grid map of New York, with each unit on the grid representing 0.125 miles is the Empire State building is located at (4,-4) in Central Park is located at (-14,8), which is the direct distance( Not walking distance, which would have to account for bridges in roadways) between the two landmarks in miles? Round your answer to two decimal places if necessary
Use the distance formula to solve for the direct distance from (4,-4) up to (-14,8)
\(\begin{gathered} d = \sqrt {(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2} \\ d = \sqrt {(-14 - 4)^2 + (8 - (-4))^2} \\ d = \sqrt {(-18)^2 + (12)^2} \\ d = \sqrt {{324} + {144}} \\ d = \sqrt {468} \\ d=\sqrt{36\cdot13} \\ d=6\sqrt{13} \end{gathered}\)Since 1 grid is equal to 0.125 miles. Multiply the distance in units and we get
\(6\sqrt{13}\cdot0.125\text{ miles}=2.704163457\)Rounding to 2 decimal places, the direct distance is 2.70 miles.

The completed statements with regards to the compound interest of the amount in the account are;
If the account has a 5% interest rate and is compounded monthly, you have $101.655 million money after 2 years
If the account has a 5% interest rate compounded continuously, you would have $106.096 million money after 2 years
What is the compound interest on an amount?Compound interest is the interest calculated based on the initial amount and the accumulated interests accrued from the periods before the present.
The compound interest formula indicates that we get;
\(A = P\cdot (1 + \frac{r}{n}) ^{n\cdot t}\)
Where;
P = The principal amount invested = $92 million
r = The interest rate = 5% monthly
n = The number of times the interest is compounded per annum = 12
t = The number of years = 2 years
Therefore; \(A = 92\cdot (1 + \frac{0.05}{12}) ^{12\times 2}\approx 101.655\)
The amount in the account after 2 years is therefore about $101.655 million
The formula for the amount in the account if the principal is compounded continuously, we get;
A = \(P\cdot e^{(r\cdot t)}\)
Therefore, we get;
\(A = 96 \times e^{0.05 \times 2} \approx 106.096\)
The amount in the account after 2 years, compounded continuously therefore, is about $106.096 million

Which statement about the function
f(x) = |x - 3| + 4 is true?
A.
B.
C.
D.
The minimum value of the function is 4.
The domain is
x > 3.
3
The range is all real numbers.
The axis of symmetry is at
x = -3.
Answer:
The minimum value of the function is 4.
Step-by-step explanation:
The minimum value of the function is 4.
There is no number of x that when the absolute value of (x-3) can be negative. For x = 3, the value is 0 and f(x) becomes 4 when the 4 is added to 0.
The minimum value of the function is 4.
Not true. If x is > 3, then f(x) will be greater than 4.
The range is all real numbers.
Not true, f(x) can never be less than 4, which occurs when x = 3
The axis of symmetry is at x = -3.
Not true. See attached graph. It is at x = 3.
Write the equation of the line that passes through the points (−7,5) and (-7,-8).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
x = -7
Step-by-step explanation:
First we find the slope using
m = ( y2-y1)/(x2-x1)
= ( -8 - 5)/( -7 - -7)
= (-8-5)/(-7+7)
= -13/0
This means the slope is undefined and the line is vertical
Vertical lines are in the form
x= constant and the constant is the x value of the points
