The equation of the linear function is y = 8x - 5.
What is a linear function?
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx.A linear function has one independent variable and one dependent variable.Slope formula:
m = (y₂ - y₁) / (x₂ - x₁)
Taking first two points from the given table
m = (3 + 5) / 1 - 0
m = 8
slope m = 8
Use one slope and one point formula to find the linear equation
y - y₁ = m (x - x₁)
y + 5 = 8 (x - 0)
y = 8x - 5
Hence, the equation of the linear function is y = 8x - 5.

y=-3/4x-9/2 is the equation of a line that goes through both transformed points.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
we must translate the given point (x,y) into the translation given. We begin with the 90 degree clockwise rotation such that
90 degree clockwise rotation = (x, y) => (y, -x)
we translate the coordinate (y, -x)
2 units to the right such that
(y-4, -x - 2)
So the coordinate of points changed (1,2) and (-4,6) from (-2, -3) and (2, -6)
m=-6-(-3)/2-(-2)
m=-3/4
Now let us find the y intercept.
-3=-3/4(-2)+b

(c-5)
explain how you got your answer
Answer: c = -14 over 3 (c = -14/3)
Step-by-step explanation:
1. Distribute: 5c + 4 = 2(c - 5) --> 5c + 4 = 2c - 10
2. Subtract 4 From Both Sides: 5c + 4 = 2c - 10 --> 5c + 4 - 4 = 2c - 10 - 4
3. Simplify: 5c = 2c - 14
4. Subtract 2c From both sides: 5c = 2c - 14 --> 5c - 2c = 2c - 14 - 2c
5. Simplify: 3c = 14
6. Divide Both Sides By The Same Factor: 3c divided by 3 = -14 divided by 3
7. Simplify: c = -14 over 3
Is it wrong to split an infinitive?
A word is put between to and the verb while splitting an infinitive. In terms of grammar, splitting an infinitive is acceptable.
In other cases, it might even be more logical to do so. An infinitive is a verb's to form, such as "to go" or "to be."
When it is said that infinitives should never be split, it means an adverb should never come before the verb in the sentence "to confidently proceed."
As we know split infinitive is one in which the word "to" and the verb in the base (infinitive) form of the verb are separated by one or more words.
Adverbs are the words that split infinitives the most frequently.

Answer:
The last graph that is a straight line represents y as a function of x
Step-by-step explanation:
In order for a graph to be considered a function, it can't intercept the same value twice. To test this, use the vertical line test to see if the graph hits the line twice. If it does, then it is not a function. But if the line hits the graph only once, then it is a function.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse.In ΔABC
AC² = AB² - BC² (∴Pythagoras theorem)
AC = √25² - 7²
AC = √625 - 49
AC = √576
AC = 24 feet
As after sliping length of ladder remains same ⇒ DE = 25 feet and feet 4 feet.
Let say x be the length of how much the ladder slips.
New height = DC = AC - AD = 20 feet
EC = (x + 7 ) feet
In ΔDEC,
DE² = DC² + EC² (∴Pythagoras theorem)
25² = 20² + (x + 7)²
(x + 7)² = 225
x + 7 = 15

How do you solve 4 linear equations?
The easiest way to solve 4 linear equations is to use the substitution method. This involves substituting the values of one equation into the other equations until you are left with a single equation that can be solved for the remaining variable.
if you have the following four linear equations:
A + B = 10
A - B = 2
A + C = 12
A - C = 3
You can substitute A = 10 - B into the third and fourth equations to get:
10 - B + C = 12
10 - B - C = 3
Then you can add the two equations together and solve for C:
2B + 2C = 15
2C = 15 - 2B
C = (15 - 2B) / 2
Once you have C, you can substitute it into one of the other equations to solve for B:
A + B = 10
A = 10 - C
B = 10 - (15 - 2B) / 2
B = 5 - (15 - 2B) / 2
2B = 10 - 15
2B = -5
B = -2.5

The radius of the base of a cone is decreasing at a rate of 222 centimeters per minute. The height of the cone is fixed at 999 centimeters. At a certain instant, the radius is 131313 centimeters. What is the rate of change of the volume of the cone at that instant (in cubic centimeters per minute)?.
If the radius of the base of a cone is decreasing at rate of 2 cm/minute and the height is kept constant at 9 cm, the rate of change of the volume at radius 13 cm is 489.4 cm³/minute
To calculate the rate of change, we need to take the derivative of the variables with respect to time.
The volume of a cone is given by:
V = 1/3 . πr²h
Where:
r = radius of the base
h = height
Since the height of the cone is held constant, then the derivative with respect to time is:
dV/dt = 1/3 h. 2πr dr/dt
Parameters given:
dr/dt = 2 cm/minute
h = 9 cm
r = 13 cm
Hence,
dV/dt = 1/3 x 9 x 2π x 13 x 2
dV/dt = 489.4 cm³/minute
Hence, at radius 13 cm, the rate of change of the volume is 489.4 cm³/minute

find an equation of the curve that passes through the point (0, 1) and whose slope at (x, y) is 5xy.
The equation of the curve that passes through the point (0, 1) and whose slope at (x, y) is 5xy is [tex]e^{\frac{5x^2}{2} }[/tex] .
The slope of the curve is 5xy.
Therefore:
dy/dx = 5xy
dy/y = (5x)dx
Then,
The integrate both sides giving us
ln(y) = (15x²)/2 + C
Since, the curve passes through (0,1) .
Therefore, x=0 and y=1 for solving 2
ln(1) = 0/2 + C
0 = 0 + C
⇒ C = 0
We now,
substitute C back in and isolate y
ln(y) = (15x²)/2
⇒ y = e(15x²) / 2

The rate the level in the tank falling when the height of the syrup level is 3 feet is 8/π feet per minute. The result is obtained by using the rate of change concept.
How to count the rate of change?A conical tank containing syrup is draining.
The rate of water volume decreasing, dV/dt = 8 ft³/min.Height of conical tank = 6 ft.Radius of conical tank = 2 ft.Find the rate of syrup level falling (dh/dt) when h = 3 ft!
See the picture in the attachment!
By the similar triangles, we get
r/h = 2/6
r/h = 1/3
r = 1/3 h
Find the volume of the syrup left at a certain height.
V = 1/3 πr²h
V = 1/3 π(1/3 h)²h
V = 1/3 π(1/9) h² h
V = 1/27 πh³
The rate of syrup level falling is
dV/dt = dV/dh . dh/dt
dV/dt = d/dt [1/27 πh³] . dh/dt
dV/dt = 1/27 π 3h² dh/dt
8 = 1/27 π 3(3)² dh/dt
8 = π dh/dt
dh/dt = 8/π ft/min

Step-by-step explanation:
Multiply both sides of the first equation by-5 or 2 (I'll use 5) and both sides of the second equation by - 2 or 3 (I'll use -2).
3x - 2y = 2
5(3x-2y)= 5(2)
-15x - 10y = 10
2x - 5y = 27
-2(2x - 5y) = -2(27)
-4x + 10y = -54
Now you see that the absolute values of the y-values of the 2 equations match up . They are still the same equations but scaled up.
-15x + 10y = 10
-4x - 10y = -54
Add to eliminate y.
-11x = 44
Divide both sides by -11.
[tex]\frac{-11x}{-11} = \frac{44}{-11}[/tex]
x = -4
Plug back in to either equation to solve. I'll use the first equation.
3x - 2y = 2
x = - 4
3(-4) - 2y = 2
-12 - 2y = 2
Add 12 on both sides.
-12 + 12 - 2y = 2 + 12
- 2y = 14
Divide -2y on both sides.
