Which is the equation of the given line?
x = 1 y = 2x y=x y=1 (need help ASAP)
Answer:
y = 1
Step-by-step explanation:
Since the line is a horizontal line through 1, y = 1.
The sum of two numbers is -6. Their difference is 36. What is the smallest number?
Let first number be x.
Let second number be y.
According to question,
x+y=36…….(equation 1)
and
x-y=6…..(equation 2)
equation 2 can be written as , x=6+y……(equation 3)
Put equation 3 in equation 1,
6+y+y=36
6+2y=36
2y=36–6
2y=30
y=30/2
y=15
now, put y=15 in equation 1,
x+15=36
x=36–15
x=21
So, numbers are 21 and 15.

The cost for bowling includes $4.00 for shoes and $4.75 for each
game bowled. Which equation represents the amount, in dollars, y,
for x games bowled?
Answer:
y = 4.75x + 4
Step-by-step explanation:
it would be $4.75 for each game and you would only pay for shows once
The equation that represents the amount, in dollars, y,
for x games bowled is y = 4.00 + 4.75x
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The cost for bowling includes a fixed cost of $4.00 for shoes, and an additional cost of $4.75 for each game bowled.
y = 4.00 + 4.75x
This equation can be interpreted as follows: the fixed cost of $4.00 is added to the variable cost of $4.75 per game, multiplied by the number of games bowled (x).
The result is the total cost, represented by y
Therefore,
The total cost for x games bowled can be represented by the equation:
y = 4.00 + 4.75x
where y is the total cost in dollars, and x is the number of games bowled.

Answer:
[tex]\begin{bmatrix}-1 & 2 \\ \frac{3}{2} & -\frac{5}{2} \end{bmatrix}[/tex]
Step-by-step explanation:
Inverse of a matrix is given by,
[tex]\begin{bmatrix}a & b\\ c & d\end{bmatrix}=\frac{1}{ad-bc}\begin{bmatrix}d & -b\\ -c & a\end{bmatrix}[/tex]
By using this property,
[tex]\begin{bmatrix}5 & 4\\ 3 & 2\end{bmatrix}^{-1}=\frac{1}{(5\times 2-4\times 3)}\begin{bmatrix}2 & -4\\ -3 & 5\end{bmatrix}[/tex]
[tex]=-\frac{1}{2}\begin{bmatrix}2 & -4\\ -3 & 5\end{bmatrix}[/tex]

Find the horizontal distance x the escalator covers to the nearest tenth of a foot.
Given:
Length of escalator = 26 ft
Angle of depression = 41 degrees
To find:
The horizontal distance x the escalator covers to the nearest tenth of a foot.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
Using this formula for the given triangle, we get
[tex]\cos 41^\circ=\dfrac{x}{26}[/tex]
[tex]26\cos 41^\circ=x[/tex]
[tex]26(0.7547)=x[/tex]
[tex]19.6222=x[/tex]
Round the value to the nearest tenth.
[tex]x\approx 19.6[/tex]
Therefore, the escalator covers 19.6 ft horizontally.

There are 30 students in an art class. Fourteen of the students are girls.
What is the ratio of boys to girls?
A.7:8
B.8 :7
C.8:15
D.14:40
E.30:14
Answer: B
Step-by-step explanation: To get the boys part of the ratio you will have to subtract 30 students and 14 students that are girls because all together there are 30 students and since we only know that 14 of them are girls that leaves the rest of the students boys. 30 - 14 = 16 so now we know how many boys there are. 16:14 can be reduced by 2 and that equals to 8:7.
Hope this helps!
The ratio of boys to girls is equal to: B. 8 :7
Given the following data:
Total students = 30 studentsNumber of girls = 14 studentsTo calculate the ratio of boys to girls:
How to calculate ratio.First of all, we would determine the number of boys in the art class by subtracting the number of girl students from the total number of students in this class.
[tex]Total \;students = boys + girls\\\\30=boys + 14\\\\Boys =30-14[/tex]
Boys = 16 students.

The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x
Answer:
85.1 ft
Step-by-step explanation:
The extreme water slide forms a 20 angle with the tower it leans against 80 feet above the ground find the length of the slide x
We solve using the Trigonometric function of Cosine
cos y = adjacent/hypotenuse
y = angle = 20°
Adjacent = 80 ft
Hypotenuse = ?
cos 20 = 80/Hypotenuse
Hypotenuse = 80/cos 20
x = 85.134221798 ft
Approximately = 85.1 ft
Length of the slide = 85.1 ft

Identify the similar triangles in the figure then find the value of X.
A. Write the similarity statement in the form of triangle~triangle.
B. What is the value of X.
Answer:
A. ∆ABD ~ ∆CDE
B. x ≈ 5.3
Step-by-step explanation:
A. The Acute Angle Similarity Theorem states that when an acute angle in one right triangle is congruent to a corresponding acute angle in another, both right triangles are said to be similar to each other.
<B ≅ <D (both are right angles)
<A ≅ C,
Therefore, ∆ABD ~ ∆CDE
B. Since ∆ABD ~ ∆CDE, corresponding sides would be proportional to each other. This means that:
DE/BD = CD/AB
Substitute:
6/8 = 4/x
Cross multiply
6*x = 4*8
6x = 32
6x/6 = 32/6
x ≈ 5.3 (nearest tenth)
What is the measure of ∠L?
Enter your answer in the box. Round only your final answer to the nearest hundredth.
m∠L= °
====================================================
Explanation:
We set up a cosine ratio, since we want to connect the adjacent and hypotenuse. Then we'll use the inverse cosine, which is also known as arccosine, to isolate the angle value.
This is what your steps could look like:
cos(angle) = adjacent/hypotenuse
cos(L) = LM/LN
cos(L) = 18/60
cos(L) = 0.3
L = arccos(0.3)
L = 72.542396876278 which is approximate
L = 72.54 degrees approximately
Make sure your calculator is in degree mode.
