Answer:
x=1
Step-by-step explanation:
y=x²-2x-8
First, we solve for the vertex
The equation for the vertex is -b/2a
Substitution:
-b/2a
=-(-2)/(2*1)
=2/2
=1
Therefore the equation for the line of symmetry is x=1
Hope this helps!

Find the area of the composite figure.
69 square feet
48 square feet
70 square feet
82 square feet
Answer:
69ft² (69 square feet)
Step-by-step explanation:
8x7=56ft
6x2=12ft
2x1÷2=1ft
56+12+1=69ft²
Answer:
Option A, 69 square feet
Step-by-step explanation:
Step 1: Determine the area of the rectangle
[tex]A = l * w[/tex]
[tex]A = 7\ ft * 8\ ft[/tex]
[tex]A = 56\ ft^2[/tex]
Step 2: Determine the area of the second rectangle
[tex]A = l * w[/tex]
[tex]A = 6\ ft * 2\ ft[/tex]
[tex]A = 12\ ft^2[/tex]
Step 3: Determine the area of the triangle
[tex]A = \frac{h * b}{2}[/tex]
[tex]A = \frac{(7\ ft - 6\ ft)*2\ ft}{2}[/tex]
[tex]A = \frac{1\ ft * 2\ ft}{2}[/tex]
[tex]A = \frac{2\ ft^2}{2}[/tex]
[tex]A = 1\ ft^2[/tex]
Step 4: Determine the total area
[tex]A_{total} = 56\ ft^2 + 12\ ft^2 + 1\ ft^2[/tex]
[tex]A_{total}=69\ ft^2[/tex]
Answer: Option A, 69 square feet

Answer:
x -3y = - 3
Step-by-step explanation:
Slope of line m = (0 -1 )/(-3 - 0) = 1/3
y - intercept b = 1
Equation of line in slope-intercept form is given as:
y = mx + b
Plugging m = 1/3 and b = 1 in the above equation, we find:
y = 1/3 x + 1
-> 3y = x + 3
-> x -3y = - 3
This is the required equation of line.

Solve the linear system
x+y=5
x-2y=-1
Find the ratio of the solution's y-coordinate to its x-coordinate.
Answer:
2:3
Step-by-step explanation:
x + y = 5 -----> y = 5 - x
x - 2y = -1
x - 2(5 - x) = -1
x - 10 + 2x = -1
3x - 10 = -1
3x = 9
x = 3
(3) + y = 5
y = 2
Solution to this system: (3,2)
Ratio of y to x = 2:3

3. 1/2 ft
Step-by-step explanation:
We know that the quilt is the shape of a square, since we are told that the main design has the same length sides of 5 ft.
Area of a square = s² (where s is the side length)
If the finished quilt has an area of 36 ft² then the length of one side is:
⇒ s = √(36) = 6 ft
Side length of main design = 5 ft
Side length of finished quilt = 6 ft
6 - 5 = 1 ft
Therefore, the border increased the total length of each side by 1 ft
As the border goes around the whole quilt, this means that the extra 1 ft needs to be divided by 2, so that each side has an equal amount added.
Therefore, the width of the border is 1/2 ft
**see attached diagram. Main design is shown in blue, border is shown in green**

Patrice says that she can find the length of the diagonal, c, of the rectangular prism by using the Pythagorean theorem twice.
Drag equations and pictures into the table below to show her work.
Answer:
see attached
Step-by-step explanation:
The first application of the Pythagorean theorem is used to find the diagonal of one face. That is called 'a' in this problem. Then the second application of the Pythagorean theorem uses that value of 'a' along with the remaining prism dimension to find the space diagonal 'c'.
6² +8² = a²12² +a² = c²__
You don't actually have to find 'a', because you only need the value of a². Using the first equation to substitute into the second equation gives ...
6² +8² +12² = c²

Answer:
[tex]beinggreat78~here~to~help.[/tex]
Circumference: 44(round to nearest 10)
Area: 154(round to nearest ten)
To do this problem, let's start with circumference, because we must know that before finding area.
[tex]C=2\pi r=2*\pi *7~rounds~to~43.9823[/tex]
Next, find the area by using the circumference. This time, we will use the exact numbers.
[tex]A=\pi r2\\C=2\pi r[/tex]
Now, solve for area.
[tex]A=\frac{ C^2}{4\pi }=\frac{43.98^2}{4 * \pi } ~rounds~to~153.93806[/tex]
With that information, the problem has been solved.

What is the value of x for the following equation?
Working with fractions can be tricky, so I like to start by multiplying everything by the LCM of the denominators of the fractions.
In this case, both fractions have a denominator of 4, which means that the LCM is 4 and we will be multiplying everything by 4.
1/4x - 1 = 3/4x - 5
---The below equation looks much more familiar and appears easier to solve.
1x - 4 = 3x - 20
-4 = 2x - 20
16 = 2x
x = 8
Answer: C, x = 8

Cassidy is going to the county fair with her friends but can only stay at the fair for 3 hours. The fair offers two different pricing structures. Cassidy can purchase an all-day pass with unlimited rides for $45.00 or she can pay an admission fee of $9.00 and pay $4.00 for each ride. If Cassidy rides 12 rides, how much does she save by buying the all-day pass?
A. $12.00
B. $21.00
C. $They both cost the same
D. $51.00
Answer:
Option A.
Step-by-step explanation:
The all- day pass is just $45.
For the other pass, we need to do 4 x 12 + 9.
4 x 12 + 9
48 + 9
57.
57 - 45 is 12.
Members of a soccer team raised $1428 to go to a tournament. They rented a bus for $955.50 and budgeted $31.50 per player for meals. Write and solve an equation which can be used to determine p, the number of players the team can bring to the tournament.
Equation:
Answer: p =
Answer:
16 players can be brought to the tournament. The equation is written within my step-by-step explanation.
Step-by-step explanation:
Variable p = number of players
Set up an equation:
974.50 + 60.75p = 1946.50
Isolate variable p:
60.75p = 972
Divide:
p = 16
Check your work:
974.50 + 60.75(16) = 1946.50
974.50 + 972 = 1946.50
1946.50 = 1946.50

Use the form |x-b|<=c or |x-b|>=c to write an absolute value inequality that has the solution set -1<=x<=3.
An absolute value inequality that has a solution set -1<=x<=3 is |x-1| <= 2
What is the solution set for an inequality?The set of values of the variable involved in the inequality for which the considered inequality holds true is called the solution set for that inequality.
We've to find an absolute value inequality that has the solution set
-1 <= x <= 3
1+2 = 3
and 1 - 2 = 3
Therefore, we can rewrite the considered inequality as:
1-2 <= x <1+2
Subtracting 1 from all the sides:
-2 <= x-1 <= 2
This is written as:
|x-1| <= 2 (it is because [tex]|x| \leq a \leftrightarrow-a \leq x \leq a[/tex] )
Thus, an absolute value inequality that has a solution set -1<=x<=3 is |x-1| <= 2
