Step-by-step explanation:
Certainly we can estimate y = tan x from the graph of this function, for any x at which the function is defined. Don't expect exact values, however.
Find the value f x,
[tex]7x-\left(x-12\right)=32-4x[/tex]
Answer:
x = 2.
Step-by-step explanation:
7x - (x - 12) = 32 - 4x Distributing the negative over the parentheses:-
7x - x + 12 = 32 - 4x Bringing like terms together:-
7x - x + 4x = 32 - 12 Simpifying:
10x = 20
x = 2.
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
In order to solve for the variable [tex]x[/tex], simply move all terms with the variable to one side and all constants to the other. [tex]7x-(x-12)=32-4x[/tex] => [tex]7x-x+12=32-4x[/tex] => [tex]6x+12=32-4x[/tex] => [tex]10x=20[/tex] => [tex]x=2[/tex].
You can check this answer by plugging it back into the equation as a substitute for the variable. [tex]7(2)-(2-12)=32-4(8)[/tex] => [tex]14-(-10)=32-8[/tex] => [tex]24=24[/tex], since the equation is true, this proves that x = 2 is the correct answer.

Triangle ABC has measure of angle BAC equal to 30 degrees and the measure of angle ABC is equal to 75 degrees. The side BC of the triangle is extended till D. The angle ACD is labeled as x.
Answer:
105
Step-by-step explanation:
First find the third angle inside the triangle:
180 - 30 - 75 = 75
Then find x:
180 - 75 = 105

B ∪ C = (-∞, ∞)
B ∩ C = [1, 7)
Step-by-step explanation:
B ∪ C: The union of two sets or intervals is the set of elements which are in either set.
B ∩ C: The intersection of two sets or intervals is the set of elements which are in both sets.
Interval notation symbols
Square brackets [ ]: both endpoints are included in the set.
Round brackets ( ): both endpoints are excluded in the set.
Round, square ( ]: left endpoint is excluded and right endpoint is included in the set.
Square, round [ ): left endpoint is included and right endpoint is excluded in the set.
Given:
B = {z | z ≥ 1}C = {z | z < 7}Therefore,
B = [1, ∞)
C = (-∞, 7)
Therefore, B ∪ C = (-∞, ∞)
As z is either less than 7, or equal to or more than 1 then the intersection is:
B ∩ C = {z | 1 ≤ z < 7} = [1, 7)
Answer:
See below ~
Step-by-step explanation:
B ∪ C = {∞}As all numbers will be included, the union of the sets is equal to all real numbers (infinity)B ∩ C = {1, 2, 3, 4, 5, 6}Only the numbers that are greater than or equal to 1, but less than 7can someone help me pls im really confused???

The diagram is a floor plan for a new building. Find the perimeter.
Answer:
154
Step-by-step explanation:
the perimeter is the summation of all the sides of the plane. so
15 + 14 + 20 + 9 + 15 + 13 + 50 + 18 = 154
i think this is ✅
Using the labelled size of segments, the perimeter of the given figure is 154 units. Hence, the fourth option is true.
Use the concept of perimeter defined as:
The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges.
According to the figure,
The perimeter of the given building is the sum of the lengths shown in the figure.
18 + 15 + 14 + 20 + 9 + 15 + 13 + 50 = 154.
Hence,
The required perimeter is 154 units, which is option fourth.

Answer:
Wyatt must get a score of 150 on Exam B in order to do equivalently well as he did on Exam A.
Step-by-step explanation:
Let's calculate the test statistic of each score based on the mean and standard deviation of each test.
This statistic will show us how far from the mean, measured in standard deviations, Wyatt's test score is.
The formula for the test statistic is:
[tex]\displaystyle Z = \frac{x- \mu}{\sigma}[/tex] x = observed value[tex]\mu[/tex] is the population mean [tex]\sigma[/tex] is the population standard deviationLet's calculate the test statistic for each test.
Exam A:
[tex]\displaystyle Z = \frac{45-35}{5} = \frac{10}{5}= 2[/tex]Exam B:
[tex]\displaystyle Z = \frac{x-100}{25}[/tex]Since we want the test statistic to be the same for both exam A and exam B, let Z = 2 and solve for x for Exam B.
[tex]\displaystyle 2 = \frac{x-100}{25} \\ 50 = x - 100 \\ x = 150[/tex]Wyatt must get a score of 150 on Exam B in order to do equivalently well as he did on Exam A. This score means that Wyatt is 2 standard deviations from the mean score on Exam B as he scored on Exam A.
Aisha is ordering a taxi from an online taxi service. She has to pay a flat charge just to
order the taxi, and then has to pay per mile, depending on how far she travels. She
wrote an equation to represent her total cost, y = 2.8x + 2, where y represents the
total cost in dollars and cents, and a represents the number of miles she travels,
What could the number 2 represent in the equation?
Answer:
The flat charge
Step-by-step explanation:
The number 2 could represent the flat charge in the equation because a flat charge never changes. In the equation, the 2 (y-intercept) is the only term that does not change. The value of 2.8x depends on what the value of x is, and the value of y depends on what the value of 2.8x + 2 is. Therefore, 2 could represent the flat charge in the equation.

If I make $50 very two weeks, how much will I make in 31 days.
Answer:
$110.71
Step-by-step explanation:
31 Days has 4 weeks and 3 days
4 weeks is 2 weeks twice meaning 100$
The three extra days would be 3/14 of 50$ which is $10.71
Therefore, the answer is $110.71
Answer:
$110.67
Step-by-step explenation
First find how much you make every day.
To do that, divide $50 by 14 days which is $3.57 per day.
Next, multiply $3.57 by 31 days which is $110.67
Multiply and simplify the product. 2i(4 – 5i) select the product. –2i 2i –10 8i 10 8i

What is multiplication?It is also known as the product. If the object n is given to m times then we just simply multiply them.
The expressions are 2i and (4 – 5i).
Then the product of the expression will be given as

2) Rachel wanted to drink exactly three bottles of water each day, so she bought twenty-six
bottles when they were on sale. How many more bottles will she need to buy on the last
day?
Answer:
1
Step-by-step explanation:
Twenty-Six is not a multiple of three so you know it won't be 26. Counting by threes goes 3, 6, 9, 12, 15, 18, 21, 24, 27, 30. Twenty-seven is the closest number to 26 which is higher than 26. Twenty-six + 1 = 27. That means that 1 is the answer.

Answer:
So the Answer will be D.
Step-by-step explanation:
Cuz if you look it up online it will give you words or maybe links that youu shouldn't look at cuz they don't really give it to you. It shows that ''A rotation turns each point on the preimage a given angle measure around a fixed point or axis. Each point on triangle ABC is rotated 45° counterclockwise around point R, the center of rotation, to form triangle DEF.'' So indee that D. is right. (I am only 11 and i am helping lol)
