what is the equation of the line that passes through the point(-6,-7) and has a slope of 1/3
Answer:
The equation of the line that passes through the point (-6, -7) and has a slope of 1/3 is:
x - 3y + 15 = 0
Step-by-step explanation:
The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).
To find the equation of the line that passes through the point (-6, -7) and has a slope of 1/3, we can use the point-slope form of a line:
y - y1 = m(x - x1)
Where (x1, y1) is a point on the line and m is the slope of the line.
Plugging in the given values, we have:
y - (-7) = (1/3)(x - (-6))
Which simplifies to:
y + 7 = (1/3)x + 2
Multiplying both sides by 3, we have:
3y + 21 = x + 6
Subtracting 21 and 6 from both sides, we have:
3y - x - 15 = 0
Therefore, the equation of the line that passes through the point (-6, -7) and has a slope of 1/3 is:
x - 3y + 15 = 0

The Domain and range tends to (-∞,∞) and for more clarity see the graph mentioned below.
Define Domain and Range
The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. Domain = the set of all x-coordinates Range = the set of all y-coordinates The domain and range of a function are the components of a function. The domain is the set of all the input values of a function and range is the possible output given by the function. Domain→ Function →Range.Given expression is,
f(x) = -1/4x³ + 4x - 3
In this x ∈ R, so
Domain = (-∞,∞) , { x|x ∈ R }
Range = (-∞,∞) ,{ y|y ∈ R }

Lines c and d are parallel lines cut by transversal p.
Horizontal and parallel lines c and d are cut by transversal p. On line c where it intersects with line p, 4 angles are formed. Clockwise, from uppercase left, the angles are: 1, 2, 3, 4. On line d where it intersects with line p, 4 angles are formed. Clockwise, from uppercase left, the angles are: 5, 6, 7, 8.

What is a median of a triangle?A median of a triangle is a line segment that extends from a vertex of a triangle to the midpoint of the side opposite the vertex
The midpoints of the sides of the triangle = F, B, and D
The midpoint of EC = F
The midpoint of AC = B
Midpoint of AE = D

Given the logarithmic values as,
log₃ (t) = 5.44

log₃ (z) = 7.74
Now, the value of the expression can be written as,
12 log₃ (z⁷ / y⁵t²)
= 12 { log₃ (z⁷) - [ log₃ (y⁵) + log₃ (t²) ] }
= 12 { 7log₃ (z) - [ 5log₃ (y) + 2log₃ (t) ] }
= 12 [7×7.74 - (5×11.03 + 2×5.44)]

You are designing a rectangular poster to contain 48 in^2 of printing with a 3-in margin at the top and bottom and a 1-in margin at each side. What overall dimensions will minimize the amount of paper used?
To minimize the amount of paper used to create a rectangular poster with a given amount of printing and specific margins, you can use the formula for the area of a rectangle to determine the dimensions that will minimize the area of the poster.
In this case, the area of the poster must be at least 48 square inches to contain the printing, and the margins at the top and bottom must be 3 inches each, for a total of 6 inches. The margins at the sides must be 1 inch each, for a total of 2 inches. Therefore, the minimum area of the poster is 48 + 6 + 2 = 56 square inches.
To minimize the amount of paper used, we want to find the dimensions of the poster that will have the smallest possible area while still satisfying the constraints on the margins and the amount of printing. We can do this by using the formula for the area of a rectangle:
A = lw
where A is the area of the rectangle, l is the length, and w is the width.
In this case, we want to find the length and width that will minimize the area of the rectangle while still satisfying the constraints on the margins and the amount of printing. We can do this by setting the area of the rectangle equal to the minimum area we calculated above (56 square inches) and then solving for the length and width:
A = lw = 56
lw = 56
We can then use the constraints

a quadratic equation can be written in vertex form or in standard form sometimes one form is more beneficial than the other Identify which form would be more helpful if you needed to do each task listed below and explain why. A .factor the equation. B graph the parabola.C identify the vertex minimum or maximum of the parabola D and solve the equation using the quadratic formula
a. In order to factor the equation, the vertex form needs to be expanded to the standard form first, to obtain the factors of the equation
b. The parabola is easily graphed with the information on the vertex given in the vertex form of the quadratic equation
c. The vertex, minimum or maximum of the parabola are easily obtained in the vertex form of the quadratic equation
d. The quadratic formula is defined based on the standard form of the quadratic equation
Answer:
[tex]\huge{\boxed{\text{A) Standard form}}}\\\huge{\boxed{\text{B) Vertex Form}}}\\\huge{\boxed{\text{C) Vertex Form}}}\\\huge{\boxed{\text{D) Standard Form}}}\\[/tex]
Step-by-step explanation:
Vertex form is represented as: [tex]f(x) = a(x-h)^2+k[/tex], where the vertex of the parabola is (h, k).
Standard form is represented as [tex]f(x) = ax^2+bx+c[/tex], where a, b, and c are constants.
A) When factoring an equation, the sum of the roots is equal to b and the sum of the roots is equal to c, meaning standard form is the beneficial.
B) When graphing a parabola, vertex form is extremely beneficial, as it provides the vertex of the parabola, and the direction in which it opens. If "a" is positive, the vertex opens upward, while when "a" is negative, the vertex opens downward. As such, graphing is greatly eased with this information.
C) As is evident from the name, vertex form is the best for identifying the vertex of a parabola, as it is explicitly shown via the constants h and k.
D) The quadratic formula directly uses the constants a, b, and c, so working in standard form is more beneficial, as it removes the effort of solving for each constant.

what is the hypotenuse???
To find the answer to this problem, you will need to use the Pythagorean Theorem.
What is the Pythagorean Theorem?
The Pythagorean Theorem is an equation that represents the summation of the sides of a right triangle.
a² + b² = c², where a is the shortest leg of the triangle, b is the longest leg and c is the hypothenuse.
You have been given a (12) and b (16)
First, plug your given information into the equation: 12² + 16² = c²
Next, simplify your equation by squaring both terms:
12² = 144
16² = 256
Then, add these two answers together: 144+ 256= 400
This leaves you with the equation: 400 = c²
To isolate the c as an individual term, take the square root of both sides:
[tex]\sqrt{400} = \sqrt{c^{2} }[/tex]
The above equation leaves you with the answer 20 = c, which is the hypothenuse

Answer:
Step-by-step explanation:
la première planche = 2x
la deuxième = x
la troisième = x-10

4x-10 = 50
4x-10+10 = 50 +10
4x = 60
4x diviser par 4 = 60 diviser par 4

Rewrite the following equation in slope-intercept form. y − 9 = –10(x − 10)
Answer:
y = -10x + 109
Step-by-step explanation:
Given equation,
→ y - 9 = -10(x - 10)
The slope-intercept form is,
→ y = mx + b
Rewrite in slope-intercept form,
→ y = mx + b
→ y - 9 = -10(x - 10)
→ y - 9 = -10x + 100
→ y = -10x + 100 + 9
→ [ y = -10x + 109 ]
Hence, answer is y = -10x + 109.

The height of the drone would be about 132.92 feet.
What is a tangent ratio in trigonometry?
The tangent ratio is the ratio of the opposite side to the adjacent side of a right triangle. Same to the sine and cosine ratios, tangent ratios can be used to calculate the angles and sides of right-angle triangles.
Given that the angle of elevation from the first and second base to the drone is 77° 9' and 65° 45' 18", respectively.

tan 77°9 = h/AD and tan 65.75°=h/DB
AD + DB = 90
h/tan 77°9 + h/65.75° = 90
Solving this we get
h ≈ 132.92 feet.
