Which inequality in vertex form represents the region less than the quadratic function with vertex (-2, 2) and
includes the point (-4, 14) on the boundary?
Answers
Answer:
(a) y < 3(x +2)² +2
Step-by-step explanation:
You want to know the inequality representing the region less than the quadratic with vertex (-2, 2) and containing the point (-4, 14).
Vertex formThe vertex form equation for a quadratic with vertex (h, k) and some scale factor 'a' is ...
y = a(x -h)² +k
For the given vertex (-2, 2), the boundary line equation is ...
y = a(x -(-2))² +2 = a(x +2)² +2
Scale factorThe value of 'a' is positive when the curve opens upward.
Here, the point (-4, 14) has a y-value greater than that of the vertex, so we know the curve opens upward (a > 0).
The only reasonable answer choice is ...
y < 3(x +2)² +2

Answers
closed circles are at negative 2 and positive 8. everything between the points is shaded.
We have the equation:
|h - 3| [tex]\leq[/tex] 5
Remember that the equation:
|f(x)| = A
with A > 0
means that:
f(x) = A
or
f(x) = -A
Then for our case, we can rewrite:
|h - 3| [tex]\leq[/tex] 5
as:
(h - 3) [tex]\leq[/tex] 5
or
-(h - 3) [tex]\leq[/tex] 5
Now we can solve these two equations to find the two possible values of p.
From the first one, we get:
h [tex]\leq[/tex] 8
Now from the other equation, we can get the other solution:
h [tex]\geq[/tex] -2
Then the correct option is:
closed circles are at negative 2 and positive 8. everything between the points is shaded.

What is constant of proportionality?The constant of proportionality is known as the slope of the line.
Constant of proportionality is nothing but slope of a line
The formula for calculating slope is expressed as:
m = y₂-y₁/x₂-x₁
Given the coordinate points (2/3, 3/4 ) and (0,0).
y₂=0, y₁=3/4, x₂=0,x₁ =2/3
substitute the values of y₂=0, y₁=3/4, x₂=0,x₁ =2/3 in slope formula to get constant of proportionality.
The constant of proportionality is expressed as:
m = 3/4 × 2/3
m =6/12
m=1/2
Hence the constant of proportionality is 1/2

Answers
Using a system of equations, it is found that:
b) The domain of the solution is that Steve ran 11 miles.
c) Variable S gives the distance ran by Steve.
d) The algebraic expressions are: K = 4 + S, K + S = 26.
e) The equation is: 4 + S + S = 26.
What is a system of equations?
A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the problem.
In the context of this situation, the variables are given as follows:
Variable K: Distance ran by Kevin.
Variable S: Distance ran by Steve.
Kevin ran 4 miles more than Steve ran, hence:
K = 4 + S.
The sum of their distances is 26 miles, hence:
K + S = 26.
Replacing the first equation K = 4 + S on the second, we have that:
4 + S + S = 26
2S = 22
S = 11 miles.

The equation of the line that passes through the x-intercept ( -2,0 ) and y-intercept ( 0,1 ) is y = (1/2)x + 1.
What is the equation of line of the graph?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
From the graph, the x and y-intercept are; ( -2,0) and (0,1 )
Point 1 ( -2,0 )
x₁ = -2y₁ = 0Point 2( 0,1 )
x₂ = 0y₂ = 1First, we determine the slope of the line.
Slope m = y₂ - y₁ / x₂ - x₁
Slope m = 1 - 0 / 0 - (-2)
Slope m = 1 / 0 +2
Slope m = 1/2
Next, determine the y-intercept b by substituting the slope and a point into the equation of line formula.
y = mx + b
0 = (1/2)(-2) + b
0 = -2/2 + b
0 = -1 + b
b = 1
Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = (1/2)x + 1
Therefore, the equation of the line is y = (1/2)x + 1.

The function which will represent the given Translation will be T(x, y) = (x + 3, y - 2).
Translation may be defined as the shifting of the curve on a graph or shifting of the plotted points on a graph. The translation can be horizontal or vertical. In horizontal direction it can be shifted either left or right and in vertical direction it can be shifted either up or down. Horizontal translation always occurs on the x axis and vertical translation always occurs on the y axis. A function may be defined as an expression in which for input variable x there is output variable y. We need to translate a function T(x, y) 3 units right so the new coordinate will be T(x + 3, y). Now, translation occurs 2 units down. so, new coordinates will be T(x + 3, y -2) which is the required function.

What is slope?Finding the ratio of "vertical change" to "horizontal change" between any two unique locations on a line yields the slope. Occasionally, the ratio is written as a quotient (also known as a "rise over run"), which produces the same number for every two unique points on the same line. Negative "rise" refers to a diminishing line. The line could be functional, established by a road surveyor, or depicted in a graphic that represents a road or a roof as a description or a design.
The absolute value of the slope is used to determine how steep, incline, or grade a line is. The steeper the line, the larger the absolute magnitude of the slope. A line's direction might be either horizontal, ascending, decreasing, or vertical
If a line is rising from left to right, it is increasing. Since m>0, the slope is positive.
If a line decreases from left to right, it is said to be diminishing. The slope is inverse, or m0.
A line has zero slope if it is horizontal. This function has a fixed value.
A line's slope is ambiguous if it is vertical.

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
From the figure:
The value of y can be found by applying the concept of vertically opposite angles:
y = 109 degrees
x = [360 - 2(109)]/2
x = (360 - 218)/2
x = 71 degrees
