These two functions' graphs do indeed intersect:
Formula 1: F(X)=2X+5
The formula 2=H(X)=3X+2
INTERSECT=(3,11)
Describe function:a mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).Everywhere in mathematics are functions, which are essential for building physical connections in the sciences.
According to the given data:The first step is to generate two linear functions. I created the linear functions f(x)=2x+5 and h(x)=3x+2 (without a quadratic term). Then
You substitute a number for the x:
F(X)=2X+5 in Table 1 (H(X)=3X+2) Table 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
The two - dimensional functions will intersect at the X=3/Y=11 location, as demonstrated by both data tables, which is the answer.

What is domain and range?Mathematical procedures are comparable to those of a soda vending machine. You can choose from a variety of sodas after you deposit a particular sum of money. Similar to how we enter different numbers into functions, we also receive new numbers as the outcome. The two essential characteristics of functions are domain and range.
A soda can be purchased using quarters and one dollar bills. If pennies are put into the machine, no soda flavor will be provided. As a result, domain depicts the possible inputs, which are quarters and one-dollar bills. No matter how much you pay, a Coke machine won't give you a cheeseburger. As a result, range refers to potential outputs, or in this case, soda tastes in machine. Let's discover how to graph and determine domain and range of a given function.

What are the vertex and range of the function?
The vertex of the function is (4, 0) and the range of the function is [0, 7]
What is the range of a function?The range of a function is the set of output values of the graph.
This in other words mean the range of a function is the set of y values of the graph.
How to determine the vertex of the function?The table of values represents the given parameter
As a general rule, the vertex of a function is the smallest or the largest value of the function
On the table of values, we have the smallest function value is 0
The corresponding x value is -4
When these values are paired, we have
(x, y) = (4, 0)
This means that the vertex of the function is (4, 0)
How to determine the range of the function?The table of values represents the given parameter
Using the definition of range stated above, we have
Smallest function value = 0
Largest function value = 7
This means that the range of the function is [0, 7]

Martin's answer is wrong. The afternoon temperature in Westfield city is -10°F.
Given,
The temperature in Westfield city in morning = -2°F
The drop down temperature by afternoon = 8°F
We have to find the temperature in afternoon:
Temperature in afternoon = Temperature in morning - Drop down temperature
= -2 - 8 = -10
The afternoon temperature in Westfield city is -10°F
Martin subtracted like:

Exterior angle, theorem, and triangle sum theorem
Answer:
x = 4
The two interior angles are
14x + 6 = 14 x 4 + 6 = 62°
16x + 4 = 16 x 4 + 4 = 68°
Step-by-step explanation:
The exterior angle of a triangle is the sum of the interior angles:
Here the exterior angle is 130° and the interior angles are
16x + 4 and 14x + 6
So 16x + 4 + 14x + 6 = 130
Gathering like terms and simplifying:
16x + 14x + 4 + 6 = 130
30x + 10 = 130
30x = 120 (subtract 10 from both sides)
x = 4
The two interior angles are
14x + 6 = 14 x 4 + 6 = 62°
16x + 4 = 16 x 4 + 4 = 68°

Ryan has $16 in a savings account. The interest rate is 15% per year and is not compounded. How much will she have in 1 year? Use formula i=p*r*t, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years
Answer:
$18.4
Explanation:
At the end of the year, Ryan will have the initial saving plus the interest earned.
So, to calculate the interest earned we will use the given equation:
i = p*r*t
So, replacing p by 16, r by 0.15, and t by 1, we get:
i = 16 x 0.15 x 1
i = 2.4
Then, after 1 year, she will have:
$16 + $2.4 = $18.4
Therefore, the answer is $18.4

E) 270º counterclockwise
Answer:
C) 180°
Step-by-step explanation:
You want the angle of rotation between triangle ABC and triangle A'B'C' given that the center of rotation is point P.
AngleThe angle of rotation will be the measure of the angle APA'. We see that this angle is a straight angle with a measure of 180°.
The angle of rotation is 180°.
__
Additional comment
Another clue regarding the answer is that 90° CW is equivalent to (and indistinguishable from) 270° CCW, and vice versa. This means each of the other answer choices is repeated, so one is as good as the other. The only possible single answer choice is 180°.
The angle of rotation can always be found this way. Form an angle between a preimage point, the center of rotation, and the corresponding image point. The measure of that angle is the angle of rotation.

There is a system of equations:
Equation 1: 2x + 4y = 16

The slope of the line is -1.
A line's slope is defined as the ratio of the change in y coordinate to the change in x coordinate.
Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by the symbols y and x, respectively to calculate the slope.The common form for two-variable linear equations is Ax + By = C , where the slope is -A/C.For instance, the linear equation 7x + 3y = 1 uses standard form. Finding an equation's two intercepts (x and y) is fairly straightforward with this procedure, the slope is -7/3 .The cartesian equation for a straight line is Y = mx + c, where m stands for the gradient or slope of the line and c for the point at which it intersects the y-axis.Now the given points are : (-4,6) and (-1,3)
We know that the slope of a line is given by :
[tex]m=\frac{y_2-y_1}{x_2-x_1}.[/tex]
Now we can put the values of the points to get the slope as
