Match the diagrams to the correct congruence. Note that some diagrams may have more than one answer (select all that apply).
C. The image shows two right triangles with one pair of congruent leg and congruent hypotenuse. Therefore, the congruence is HL.
D. This shows two right triangles that share one side (a leg) and have the other leg also congruent to each other. Therefore, their congruence is LL and SAS (leg, right angle, leg).
E. This shows two triangles with a pair of congruent sides, a pair of congruent angles, and they have a common side, therefore congruent since they are the same.
So, their congruence is SAS.
F. This shows two right triangles sharing the same hypotenuse, and with a pair of congruent angles. Therefore, their congruence is HA.
G. This shows two right triangles with congruent hypotenuses, one congruent pair of legs, and two congruent pairs of angles (if we include the right angle).
So, their congruence is HA and HL.
H. The two triangles here have a right angle, a pair of congruent sides, and a pair of angles that are opposite by vertex, so they are also congruent angles.
Therefore, their congruence is ASA.
The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x − k. If g(x) is obtained by shifting f(x) down by 2 units, then what is the value of k?
k = 2
k equals one half
k = −2
k equals negative one half
Reason:
To shift down 2 units, we go from f(x) = (0.5)x to g(x) = (0.5)x - 2.
The -2 at the end means we subtract 2 from each y coordinate.
Compare this to g(x) = (0.5)x - k to find that k = 2.
two chocolate chip cookies and three brownies cost a total of 9.50. One chocolate chip cookie and two brownies cost a total of 6.00. What is the price of a chocolate chip cookie and a brownie? Show all work
Answer:
Step-by-step explanation:
Let Chocolate=X, Brownie=Y
2X+3Y=9.50 (Eq 1)
X+2Y=6.00 (Eq 2)
Multiplying Eq 2 by 2
2(X+2Y=6.00) (Eq 3)
Subtracting Eq 3 by Eq 1
2X+3Y=9.50
2X+4Y=12.00
0-Y= -2.5
Y=2.5
Putting Value of Y in Eq 2
X+2(2.5)=6.00
X+5=6
X=6-5

Value of P(5) is 0.058 by probability.
What is a math illustration of probability?
The likelihood or chance of an event happening is known as probability. For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail). P(heads) = 12 is what we write.Given that ,
p = 1 / 4 = 0.25
1 - p = 1 - 0.25 = 0.75
n = 10
Using binomial probability formula ,
P(X = x) = ((n! / x! (n - x)!) * px * (1 - p)n - x
(a) x = 5
P(X = 5) = ((10! / 5! (10 - 5)!) * 0.255 * (0.75)10 - 5
= ((10! / 5! (5)!) * 0.255 * (0.75)5
= 0.058
P(5) = 0.058
(b)
P(X > 3) = 1 - P(X \leq 3)
= 1 - P(X = 0) - P(X = 1) - P(X = 2) - P(X = 3)
= 1 - 0.776
= 0.224

The points (0,k) and (1,4) fall on a line with a slope of 9. What is the value of k?
Answer:
k = -5
Step-by-step explanation:
Slope of a line is given by
[tex]\dfrac{y_2 - y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are two points on the line
This is commonly referred to as rise/run
Given two points(0, k) and (1,4) and told that the slope is 9 we get
[tex]9 = \dfrac{4-k}{1-0}\\\\9 = \dfrac{4-k}{1}\\\\9 = 4 -k\\\\\text{Subtract 5 from both sides to get }\\9 - 4 = 4 - 4 - k\\\\5 = -k\\\\ k = - 5\\\\[/tex]

The ascending order of the given numbers is 2×[tex]10^{-4}[/tex] <0.004< 4×[tex]10^{-2}[/tex] < 0.042 < 0.24
The first number = 0.24
The second number = 4×[tex]10^{-2}[/tex]
The second number is the form of scientific notation. To compare the numbers, all the numbers should be in same form. So we have to convert the scientific notation to the decimal form
4×[tex]10^{-2}[/tex] = 0.04
The third number = 0.042
Third number is decimal form
The fourth number = 2×[tex]10^{-4}[/tex]
Convert the scientific notation to the decimal form
2×[tex]10^{-4}[/tex] = 0.0002
The fifth number = 0.004
The order of the numbers from least to greatest

2) I read 120 pages yesterday and 132 pages today.
85 pages were left to read.
O How many pages did I read yesterday and today?
Answer:
A total of 252 pages
Step-by-step explanation:
In other words, 120 pages of a book were read yesterday and 132 pages of a book were read today. There are still 85 pages left to read in order to finish the book.
This word problem may seem tricky because it throws in the “85 pages left to read”, but you don’t have to pay attention to that because all the actual question is asking is for you to add the number of pages you already read.
To figure out how many pages were read in total, you must add.
So, 120 + 132 = 252
To do this addition problem mentally:
1. Add the 100s place, so 100 + 100 = 200
2. Add the 10s place, so 20 + 30 = 50
3. Add the 1s place, so 0 + 2 = 2
4. Add up all the sums that you got, so 200 + 50 + 2 = 252
You read 120 pages yesterday and 132 pages today. The values are correct.
What is an expression?An expression is a grouping of one or more mathematical or logical operators, operands (values, variables, or other expressions), and brackets in mathematics and computer programming that denote a computation that can be evaluated to generate a value.
Let x be the number of pages that you read yesterday, and let y be the number of pages that you read today.
From the problem, we know that:
x + y = 120 + 132 (the total number of pages you read over the two days)
x + y + 85 = total number of pages in the book
We can simplify the second equation by combining like terms:
x + y + 85 = total number of pages in the book
x + y = total number of pages in the book - 85
We can substitute the first equation into the second equation to eliminate x + y:
120 + 132 = total number of pages in the book - 85
252 = total number of pages in the book - 85
total number of pages in the book = 252 + 85 = 337
Now we can substitute this value for the total number of pages in the book into the first equation to solve for x and y:
x + y = 120 + 132
x + y = 252
We can solve for one variable in terms of the other by subtracting y from both sides:
x = 252 - y
Now we can substitute this expression for x into the equation x + y = 252 and solve for y:
252 - y + y = 252
y = 132
So you read 120 pages yesterday and 132 pages today.

Determine the range of f(x) = |x| − 4. {y | −∞ < y < ∞} {y | −4 ≤ y < ∞} {y | 0 < y < ∞} {y | 4 < y < ∞}
The range of the function f(x) = |x| − 4 is {y | −4 ≤ y < ∞}.
Given the function is: f(x) = |x| − 4
first find the domain of the function.
A function's domain and range are its constituent parts. A function's range is its potential output, whereas its domain is the set of all possible input values.
domain= (−∞,∞)
Then, range is he set of all representations of domain elements or the set of all function outputs constitutes the range of the function f.
range = {y | −4 ≤ y < ∞}.
Hence we get the range of the function as {y | −4 ≤ y < ∞}.

What is the equation of the line that passes through the points (-3 , 9) and (9 , -1)? Write in your answer in slope - intercept form.
Please help
(College Algebra)
The equation of the line that passes through the points (-3,9) and (9,-1) is y= -5x/6 + 39/6 .
The equation of line passing through two points (a,b) and (c,d) is given by the equation
(y-b)=m(x-a) ,
where m is the slope of the line ..
the slope m is (d-b)/(c-a)
In the question ,
it is given that
the required line passes through the points (-3,9) and (9,-1)
by formula m= (-1-9)/9-(-3)
= -10/12
So substituting the values in the formula the equation of the line becomes
y-9 = -10/12*(x-(-3))
12*(y-9) = -10*(x+3)
12y - 12*9 = -10x-30
12y-108= -10x -30
12y = -10x-30+108
12y = -10x + 78
On Dividing both sides by 12 , we get
y= -10x/12 + 78/12
y= -5x/6 + 39/6
Therefore , the equation of the line in slope intercept form that passes through the points (-3,9) and (9,-1) is y= -5x/6 + 39/6 .
