Answer:
f(x) = 13 when x = 10.
Step-by-step explanation:
[tex]f(x)=\frac{x}{2}+8[/tex]
[tex]f(10)=\frac{10}{2}+8[/tex]
[tex]f(10)=5+8[/tex]
[tex]f(10)=13[/tex]
Therefore, f(x) = 13 when x = 10.
13
Solution:Plug in the value of x, which is equivalent to 10, instead of x:[tex]f(10)=\displaystyle\frac{10}{2} +8[/tex]f(10)=5+8f(10)=13Hope it helps.

Three students are working to find the solution set of this system of equations:
y = 3x + 10
2y = 6x – 4
Use the drop-down menus to complete the statements about each of their methods.
Mia answer choices 1:
-Intersect
-Do not Intersect
-Are the same line
Mia answer choices 2:
-One
-Zero
-Infinetly many
Roberto answer choices 1:
-Can
-Cannot
Delmar answer choies 1:
-sometimes
-never
-always
Delmar answer choices 2:
-One
-Zero
-Infinitely many
In the equation, Mia correctly graphs the two lines and sees that they do not intersect. This means that the system has zero solution.
How to illustrate the equation?From the complete question, Roberto correctly sees that y cannot be equal to both 10 more than three times a number and 2 less than three times a number at the same time.
Delmar correctly concludes that because 3x + 10 and 3x - 2 will never be equal, the system has zero solution.

Answer:
b = 5√3
Step-by-step explanation:
I would honestly just use pythag, but I'll use trig:
tanθ = opposite/adjacent
tan(30°) = 5/b
btan(30°) = 5
b = 5/tan(30°)
b = 5/(√3/3) = 15/√3
b = 15/√3 · (√3/√3) = 15√3/3
b = 5/√3
Check with pythag:
a² + b² = c²
5² + 5√3² = 10²
25 + 25(3) = 100
25 + 75 = 100 ✅

Write the equation in slope-intercept form. y=−5(x+6)+2x
Answer:
y = −3x −30
Step-by-step explanation:
Slope-intercept form: y = mx + b
y = mx + b
m = slopeb = y-intercept (when x = 0)y = −5(x + 6) + 2x <== distribute -5
y = −5(x) + −5(6) + 2x
y = −5x −30 + 2x <== combine like terms
y = −3x −30
y = −3x −30
-3 = slope-30 = y-intercept (0, -30)Hope this helps!

In a history class, 30 students were asked about other courses that they were enrolled in: 20 said they were taking math, 22 were taking English and 26 students were in either math or English. a) How many students are taking both math and English b) How many are in neither c) What percent of the students are taking math but not English
16 students take both maths and english, 4 students took neither and 15.38% of the students are taking math but not English
What is probability?Probability is the likelihood of occurrence of an event. It is given by:
Probability = number of occurrence / total possible outcomes.
Let x represent the number of students that took both maths and english, hence:
Number of students taking only maths = 20 - x
Number of students taking only english = 22 - x
26 = 20 - x + (22 - x) + x
42 - x = 26
x = 16
b) Those who took neither = 30 - 26 = 4
c) those taking only math = 20 - 16 = 4.
Percentage = (4/26) * 100 = 15.38%
16 students take both maths and english, 4 students took neither and 15.38% of the students are taking math but not English

MR X was at the crown of the statue of liberty in an island of New York City. He sighted a cargo ship coming into New York harbor with an angle of depression 35 degree. How far is the cargo ship from the base of the statue of liberty
Answer:
d = h/1.43
Step-by-step explanation:
Given
Angle of depression = 35°To Find
Distance between cargo ship and base of The Statue of LibertySolving
Let the height of the statue be 'h' and distance between it and the ship be 'd'Upon changing the viewpoint (you'll see why) to the ship viewing the top of the statue, the angle is now (90 - 35)° = 55°Then, upon taking the tan ratio of the angle between them :⇒ tan 55° = h/d
⇒ 1.43 (approx.) = h/d
⇒ d = h/1.43
[∴ Input the value of height in this formula if it is given, and you should be able to get your answer.]

the area of the Parallelogram.[tex]\underline{\clubsuit{\bf{Concept-}}}[/tex]
— Area of Parallelogram Formula
A parallelogram's area is defined as the space enclosed by two pairs of parallel lines. Since a rectangle and a parallelogram have identical properties, the area of a parallelogram equals the area of a rectangle.
— What's the procedure to find?
To find the area of the parallelogram, we have to multiply the base (denoted by B) of the perpendicular by its height (denoted by H). We should keep in mind that the base and the height of the parallelogram are perpendicular to each other, whereas the lateral side of the parallelogram is not perpendicular to the base. Thus, a dotted line is drawn to represent the height.
— Formula
Area of Parallelogram = Breadth (B) × Height (H)
[tex]\underline{\clubsuit{\bf{Solution-}}}[/tex]
Applying the formula and putting the values stated above,
[tex]\rightarrow{\sf{Area=10\times4}}[/tex]
[tex]\rightarrow{\boxed{\bf{Area=40cm^2}}}[/tex]
Hence, the area of the Parallelogram is 40cm².

help pls
Answer: B D F
Step-by-step explanation:
The statement (B), statement (D), statement (F) are true if piecewise defined function f(x) that increases over the intervals (-∞, 3) and (3,∞).
What is piecewise function?A piecewise function is one that has several curve parts in its graph.
It means that, based on the value of the input, it has countless definitions.
A piecewise function, in other words, performs differently depending on the input.
We have given a data for a piecewise function.
From the data:
[tex]\rm \lim_{n \to 3^+} f(x) = 5[/tex]
[tex]\rm \lim_{n \to 3^-} f(x) = 6[/tex]
[tex]\rm \lim_{n \to 2^+} f(x)[/tex] Does not exist because [tex]\rm \lim_{n \to 3^+} f(x)[/tex] and [tex]\rm \lim_{n \to 3^-} f(x)[/tex] are not equal.
Thus, the statement (B), statement (D), statement (F) are true if piecewise defined function f(x) that increases over the intervals (-∞, 3) and (3,∞).

A house blueprint has a scale of 1 in. : 6 ft. The length and width of each room in the actual house are shown in the table. Complete the table by finding the length and width of each room on the blueprint.
Answer:
The dimensions of the rooms in the blueprint will be Living room (), Kitchen (), Office (), Bedroom (), Bedroom (), Bathroom ().
Given information:
A house blueprint has a scale of 1 in : 4 ft.
The length and width of each room in the actual house are shown in the table below:
Living room Kitchen Office Bedroom Bedroom Bathroom
Length 20 16 8 8 20 6
width 8 16 16 16 20 8
The scale factor is of 1 in: 4 ft. So, 4 ft of actual length is equivalent to 1 inch in the blueprint.
So, the length and width of the different rooms in te house in the blueprint will be,
Living room Kitchen Office Bedroom Bedroom Bathroom
Length(in) 5 4 2 2 5 1.5
width(in) 2 4 4 4 5 2
Therefore, the dimensions of the rooms in the blueprint will be Living room (), Kitchen (), Office (), Bedroom (), Bedroom (), Bathroom ().
