Answer:x is greater than or equal to -7 but less than 9.
Step-by-step explanation:
Find the lowest and higest points on the graph.
Remember the domain is on the x - axis.
The lowest point on the graph is -7, but the dot is filled in so it must be equal to it.
The next step is that the graph is getting larger so it is greater than or equal to.
On the other side of the graph do the same but it is less than not equal because the dot is open.
Step-by-step explanation:
Find the product.

Choose 1 answer:
А
Only (1.4)
Only (-1,-4)
Both (1, 4) and (-1,-4)
Neither
Answer:
only (1,4)
Step-by-step explanation:
To find the answer, we simply substitute the x and y values into the equation.
Let‘s try (1,4)
x=1 y=4
4=7(1) -3
4=4
this is correct.
Let’s try (-1,-4)

Find the slope of the line. On a coordinate plane, a line goes through (0, negative 2) and (2, negative 4). a. -1 c. -2 b. 2 d. 1
Answer: Choice A) Slope = -1
==============================================
Explanation:
The two points given to us are (x1,y1) = (0,-2) and (x2,y2) = (2,-4)
Subtract the y coordinates
y2-y1 = -4-(-2) = -4+2 = -2
Subtract the x coordinates in the same order
x2-x1 = 2-0 = 2
Divide the two results to get the slope m
m = (y2-y1)/(x2-x1)
m = -2/2
m = -1

NEED ANSWER ASAP!!!! `For an essay contest, Annika needs to write 450 words with an absolute deviation of less than 15 words. Using w as a variable, write an absolute value inequality to represent this situation. HELP PLEASE. ONLY 10 MINUTES LEFT.
Answer:
The absolute value inequality is;
[tex]\left | w -450 \right |<15[/tex]
Step-by-step explanation:
The given information are;
The number of words Annika needs to write = 450 words
The absolute deviation of the number of words allowed = 15 words
The variable representing the number of words Annika actually wrote = w
Therefore, we have the absolute value inequality given as follows;
[tex]\left | w -450 \right |<15[/tex], which can be written in statement form as follows;
-15 < w - 450 < 15, or as follows
[tex]\left | w -450 \right |<15 \ in \ statement \ form \ is \ -15 < w - 450 < 15[/tex]
Caleb and Sergio stacked boxes on a shelf. Caleb lifted 14 boxes of equal weight. Sergio lifted 12 boxes of equal weight, but Sergio's boxes each weighed 10 lb more than Caleb's boxes.
Together they lifted a total of 354 pounds.
What was the weight of one of Caleb's boxes?
Answer:
Step-by-step explanation:
Caleb = 14x
Sergio = 12y
Sergio's boxes each weighed 10 lb more than Caleb's boxes.
y = x + 10
The equation is
14x + 12y = 354
Substitute y = x + 10
14x + 12(x+10) = 354
14x + 12x + 120 = 354
26x = 354 - 120
26x = 234
Divide both sides by 26
x = 234/26
= 9
x = 9lb
Recall,
y = x + 10
= 9 + 10
y = 19lb
Check:
14x + 12y = 354
14(9) + 12(19)
= 126 + 228
= 354
Answer: 19lb

the side elevation of a storage building is mapped on a coordinate grid. which equation could be used to determine the corresponding x value(s) of the roof line when y=8.3?
Answer:
The correct option is;
[tex]8.3 = -0.5 \times \left | x -5 \right | + 9[/tex]
Step-by-step explanation:
The coordinates of the roof are;
Starting point, = (1, 7)
Maximum height = (5, 9)
Maximum range = (9, 7)
The slope of the left portion of the roof = (9 - 7)/(5 - 1) = 0.5
The equation of the left portion of the roof is given as follows;
y - 9 = 0.5 × (x - 5)
y = 0.5 × (x - 5) + 9
The slope of the right portion of the roof = (7 - 9)/(9 - 5) = -0.5
The equation of the right portion of the roof is given as follows;
y - 9 = -0.5 × (x - 5)
y = -0.5 × (x - 5) + 9
However, when x < 5, we have;
[tex]0.5 \times \left | x -5 \right |= -0.5 \times \left | x -5 \right |[/tex]
[tex]\therefore y = 0.5 \times \left | x -5 \right | + 9 = -0.5 \times \left | x -5 \right | + 9 = 0.5 \times \left ( x -5 \right ) + 9[/tex]
When x > 5, we have;
[tex]0.5 \times \left | x -5 \right |> -0.5 \times \left | x -5 \right |[/tex]
[tex]\therefore y = -0.5 \times \left | x -5 \right | + 9 = -0.5 \times \left ( x -5 \right ) + 9[/tex]
Therefore, the equation that applies to both the left and right portion of the roof is [tex]y = -0.5 \times \left | x -5 \right | + 9[/tex]
Which gives the correct option as follows;
[tex]y = 8.3 = -0.5 \times \left | x -5 \right | + 9[/tex]

* Anyone please give me some information about the following;
• About cone and conic section.(with diagram)
• Describe how are cones, ecllipse, parabola, hyperbola are formed?
(I need full information as much as possible)
Thank you!
Answer: See explanation below
Step-by-step explanation:
A conic is a curve obtained as the intersection of the surface of a cone with a plane. The 4 types of conic section are: 1. Hyperbola 2. The Parabola 3. The Ellipse and 4. Circle.
Hyperbola: When the plane cuts the cone at an angle closer to the axis than the side of the cone a hyperbola is formed.
Cones: A cone is a three-dimensional shape that goes in a diagonal directions from a flat base to a point called the apex or vertex. A cone is formed by a set of line segments connecting from the base to the apex.
Parabola: A parabola is the curve formed by the intersection of a plane and a cone, but only when the plane is at the same slope as the side of the cone.
Ellipse: An ellipse is formed by a plane intersecting a cone at an angle to its base. All ellipses have two focal points and a center and a major and minor axis.
Circles: A circle is formed when the plane is parallel to the base of the cone.
*Note: Some of these answers are PLAGIARISED from the internet as I looked these up and copied & pasted some information, so please paraphrase if turning this in.*
Answer: see below
Step-by-step explanation:
Types of Conics are: Circles, Ellipses, & Hyperbolas.
Here is information about each one:
Circle: Two parabolas facing each other. Distance from the center to the vertices are exactly the same.
(x - h)² + (y - k)² = r²
(h, k) is the center of the circler is the radius of the circleThe 4 vertices are: (h, k+r), (h, k-r), (h + r, k), & (h - r, k)Ellipse: Two parabolas facing each other. Distance from the center to the vertices are not the same.
(x - h)²/a² + (y - k)²/b² = 1
(h, k) is the center of the ellipsea is the horizontal distance from the center to the vertices/co-verticesb is the vertical distance from the center to the co-vertices/verticesIf a > b, then vertices are: (h+a, k), & (h-a, k) and co-vertices are (h, k+b), (h, k-b)If b > a, then the vertices and co-vertices are reversed Use |a² - b²| = c² to find the distance from the center to the foci. If a > b, then Foci = (h+c, k) & (h-c, k). If b > a, then ± from the k-valueExample: (x - 1)²/9 + (y - 2)²/25 = 1
Center (h, k) = (1, 2) a = √9 = 3 b = √25 = 5
Vertices (b > a): (1, 2+5) & (1, 2-5) ==> (1, 7) & (1, -3)
Co-vertices: (1+3, 2) & (1-3, 2) ==> (4, 2) & (-2, 2)
Foci (b > a): c = √(25-9) = 4 --> (1, 2+4) & (1, 2-4) ==> (1, 6) & (1, -2)
Hyperbola: Two parabolas facing AWAY from each other. Distance from the center to the vertices may or may not be the same.
(x - h)²/a² - (y - k)²/b² = 1 or (y - k)²/b² - (x - h)²/a² = 1
↓ ↓
opens left and right opens up and down
(h, k) is the center of the hyperbolaIf x²-y², then vertices are: (h+a, k), & (h-a, k). There are NO Co-vertices.If y²-x², then vertices are (h, k+b), (h, k-b). There are NO Co-vertices.Use a² + b² = c² to find the distance from the center to the foci. If x²-y², then Foci = (h+c, k) & (h-c, k). If y²-x², then ±c from the k-valueThe slope of the asymptotes are ± b/a and pass through the center (h, k)Example: (x - 1)²/9 - (y - 2)²/16 = 1
Center (h, k) = (1, 2) a = √9 = 3 b = √16 = 4
Vertices (x²-y²): (1+3, 2) & (1-3, 2) ==> (4, 2) & (-2, 2)
Foci (x²-y²): c = √(9 + 16) = 5 --> (1+5, 2) & (1-5, 2) ==> (6, 2) & (-4, 2)
Asymptotes: m = ± 4/3 through (h, k) = (1, 2) ==> y = ± 4/3(x - 1) + 2

Given that f(x) = 4x – 3 and g(x)
2x-1, solve for g(f(2)). (5 points)
Answer:
9
Step-by-step explanation:
The first thing we shall be doing here is substituting f(x) into g(x).
Mathematically, that would be written as g(f(x))
= 2(4x-3)-1 = 8x -6 -1 = 8x - 7
Now we shall find g(f(2)) by substituting 2 into the expression above.
Mathematically, that would be 8(2) -7 = 16-7 = 9
