Answer:
x = 5 or x = -5
Step-by-step explanation:
| a b |
| c d |
det = ad - bc
| x 4 |
| 3 x |
det = x * x - 4 * 3 = x^2 - 12
x^2 - 12 = 13
x^2 = 25
x^2 - 25 = 0
(x + 5)(x - 5) = 0
x = 5 or x = -5

~AH1807Find the area of the figure.
Answers
Let’s solve for the square first.
Area=Length x Width
A=3 x 6
A=18in
Now the 2 triangles
Area=Base x Height/2
Area=1.5 x 3/2
Area=2.25in
Now add all of them together:
18+2.25+2.25=22.5in
Answer and Step-by-step explanation:
For this shape, we have to draw a line that goes through the point that is inside of the shape from top to bottom.
This creates a square and two triangles.
The area formula for a triangle is A = [tex]\frac{bh}{2}[/tex]
The area of a square is A = b*b
Half of 3 is 1.5.
Triangles (Area combined):
Since there are two triangles that are the same, we only need to find the area of of 1 triangle, and not divide by 2.
A = 3 × 1.5 = 4.5
Square:
A = 3 × 3 = 9
Now, we add them together to get the total area of the figure.
9 + 4.5 = 13.5
The area of the figure is 13.5 [tex]in^{2}[/tex].

Answer:
Part A: 3x - 23 = 28
Part B: x = 17
Step-by-step explanation:
Since 3 times x (3x) plus negative 23 is 28, we can make an equation
3x + (-23) = 28
3x - 23 = 28 (This is our equation)
3x = 51
x = 17

On the same axes graph the functions y=x^2 and y=1/x. What do you notice about the relationship between these graphs and the graph of the function you drew in part (a)?
Answers
Answer: y=1/x is the blue line and it goes straight up and down the y and x axis.
y=x^2 is the green line which is a thin "u" like shape. its going up the y axis.
y=\frac{x^{3}}{x^{2}-9} is the red line it goes up and down the y axis and diagonally across the middle of both axis'.

Step-by-step explanation:
first 2 2/3 divided by 1/3 = 8 so it is 8 cubes in that direction, then 3 1/3 divide by 1/3 = 11 so 11 cubes in that direction, which gives us a layer. 2 1/3 divided by 1/3 is 7 so we need 7 layers. multiply 8 by 11 to get the number of cubes per layer, which is 88. then 88 times 7= 616.
Did you mean: The manager of a youth soccer team bought 50 packages of socks for $10. Each. He estimated the total cost to be $5000. Create an equation that shows how many times more the manager's estimate, e, was than the actual cost, a.
Answers
Answer:
Estimated cost is 10 times more than the actual cost
Step-by-step explanation:
Packages of socks purchased = 50
Price per package = $10
Actual cost = total package purchased * price per package
Actual cost , a = 50 * $10 = $500
Estimated cost, e = $5000
Estimated costs / actual cost
$5000 / $500
= 10
Estimated cost is 10 times the actual cost

−5x−5y= −30 10x+3y= −3
Answers
Answer:
x = -3, y = 9
Step-by-step explanation:
-5x - 5y = -30
x - y = 6
x = -y + 6
10x + 3y = -3
10(-y + 6) + 3y = -3 (plug in x from the previous equation)
60 - 10y + 3y = -3
60 - 7y = -3
-7y = -63
y = 9
x = -y + 6
x = -(9) + 6
x = -3

Suppose the average automobile insurance claim for the population is $4,560 with standard deviation of $600. What is the percentage of probability that a sample of 100 claim files will yield an average claim of $4,500 or less?
Answers
Answer:
0.15866
Step-by-step explanation:
Given that :
Population mean = μ = 4560
Standard deviation, σ = 600
Sample size, n = 100
Using the relation :
(x - μ) ÷ σ/sqrt(n)
P(x ≤ 4500) :
(4500 - 4560) ÷ 600/sqrt(100)
P(x ≤ 4500) = -60 / (600/10)
P(x ≤ 4500) = - 60 / 60
P(x ≤ 4500) = - 1
P(Z ≤ - 1) :
Using the Z probability calculator ;
P(Z ≤ - 1) = 0.15866
Hence, P(x ≤ 4500) = 0.15866

3x + 10=3x - 28
Answers
Answer:
x = 27
Step-by-step explanation:
First of all the equation written on the question is incorrect, like not the image, this is because the angle of 3x + 10 and 3x - 28 is not the same, The equation will be 3x + 10 + 3x - 28 = 180
=> 6x - 18 = 180
=> 6x = 180 - 18
=> 6x = 162
=> x = 162 / 6
=> x = 27
