Given that figure ABCD is a dilation of figure KLMN, find the missing values:
The missing values in the diagram given that figure ABCD is a dilation of figure KLMN, are:
AB = 4
LM = 20
∠B = 98.87°
∠N = 141.87°
What is Dilation?Dilation is a form of transformation whereby a new figure is formed by enlarging or reducing an original figure by a scale factor. After dilation, the corresponding sides of both figures are proportional, while the corresponding angles of both figures are congruent to each other.
Find AB:
AB/KL = DC/NM
Plug in the values
AB/10 = 4/10
AB(10) = 4(10)
AB = 40/10
AB = 4
Find LM:
BC/LM = DC/NM
Plug in the values
8/LM = 4/10
8(10) = 4(LM)
LM = 80/4
LM = 20
∠B = ∠L = 98.87°
∠N = ∠D = 141.87°

Which equation matches this graph?
Answer:
y = 4"x +2
Step-by-step explanation:
We choose negative 4 because the graph lies below the asymptote and we chose positive 2 because the horizontal asymptote is on the positive section of the y axis
What’s the domain and range
Step-by-step explanation:
the domain is the interval or set of all valid x-values for the function.
and the range is the interval or set of all valid y-values (functional result values) for the function.
so, we can see here that the function would create results for all x in (- infinity, + infinity). that is the domain.
now, what result values (y-values) are possible ?
we see, that the smallest functional value is y = -2.
and from there all y-values up to +infinity are possible.
so, the range is [-2, +infinity).
please consider the chosen brackets. the "[" means the value is included in the function, a "(" means that that particular interval end value is excluded. anything bigger or smaller might be valid but not this one value.
and infinity is not a value. hence they are not included in such intervals.

Since both of them are equal to y, we can just equate them and solve.

The system of equations has been solved and the solution set of the equation are (-1,1) and (0,4).
What is a system of equation?A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.
The first equation given as,
y = 3x² + 6x + 4
The second equation given as,
y = -3x² + 4
Equate the value of y from both equation as,
3x² + 6x + 4=-3x²+4
3x²+3x²+6x+4-4=0
6x²+6x=0
6x(x+1)=0
x=0:x=-1
Put these values of x, in first equation,
y = 3(-1)^2 + 6(-1) + 4
y = 3 - 6 + 4
y=1
Put 0 on the place of x,
y = 3(0)^2 + 6(0) + 4
y = 0 +0+ 4
y=4
Thus, the system of equations has been solved and the solution set of the equation are (-1,1) and (0,4).

the table below represents a logarithmic function f(x)
The domain of the logarithm function is (0, ∞) and the range of the logarithm function will be (-∞, ∞)
What are domain and range?The domain means all the possible values of the x and the range means all the possible values of the y.
The table is shown below.
Let the logarithm function with the variables x and y. Then we have
y = logₐ x
At x = 25, the value of y will be 2. Then the value of a will be
2 = logₐ 25
2 = 2 logₐ 5
1 = logₐ 5
Then 1 can be written as
1 = log₅ 5
Then on comparing, the value of a will be
a = 5
Then the logarithm function will be
y = log₅ x
Then the domain of the logarithm function is (0, ∞) and the range of the logarithm function will be (-∞, ∞)

Find the sum.
-85+ (-81) + (-77)+...+31 + 35
Answer:
The sum of all the terms is -775.
Step-by-step explanation:
This appears to be an arithmetic sequence, with a common difference of 4.
The problem is, we don't know how many terms there are!
To find this, use the following formula:
last number = first number + (n - 1) * difference
In this case:
35 = -85 + (n - 1) * 4
35 = -85 + 4n - 4
4n = 124
n = 31
This means there are 31 terms in this sequence.
Now, for the sum. Use the following formula:
n(first number + last number), take this product and divide it by 2.
In this case:
31(-85 + 35) = -1550 / 2 = -775

Step 2: Answer the second question
We know that the total side length is 12 but we also know that the triangle base is 4 so we would subtract that from the total length and we get that the rectangle length is 8. We also know that the width is 6 so we multiply 8 by 6 and we add 24. This matches option B

What is the solution set of the inequality?
The solution set of the inequality is represented as [911,∞)
How to find the solution set of the inequality?let
x be the number of cans collected by Shane.
Therefore,
Since, Abha collected 178 more cans than Shane did.
Therefore,
Abha = 178 + x
Hence,
Also, Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling.
Therefore,
x + 178 + x ≥ 2000
2x + 178 ≥ 2000
2x ≥ 2000 - 178
2x ≥ 1822
x ≥ 1822 / 2
