In Δ JLP, m ∠ JMP = 3x - 6, JK = 3y - 2, and LK = 5y - 8 then the value of x = 32.
What is meant by the altitude of a triangle?In geometry, an altitude is a line that passes through two very specific points on a triangle: a triangle's vertex, or corner, and its opposite side at a right, or 90-degree, angle. The base is the opposite side. Triangles have three vertices and three opposite sides in common.
A triangle's altitude is the perpendicular drawn from the triangle's vertex to the opposite side. The altitude, also known as the triangle's height, forms a right-angle triangle with the base.
Since JM is at an altitude of ΔJLP, m ∠ JMP = 90
3x - 6 = 90
simplifying the above equation we get
3x = 96
Dividing both sides of the equation by 3, we get
x = 32
The value of x = 32.

3/5 multiplied by itself 4 times is a fraction exponent so it’s either b or c.
But C is [tex]\frac{3^{4}}{5}[/tex]. 3/5 multiplied 4 times means the bottom has a exponent too so it’s not c.

In a 3-digit number, the hundreds digit is four more than the units digit, and the tens digit is three less than the sum of the other two digits. If the sum of all three digits in the number is 17, find the free digits. Then find the number
Step-by-step explanation:
the number is abc
c = units digit
b = tens digit
a = hundreds digit
a = c + 4
b = (a + c) - 3
a + b + c = 17
we use the first equation in the second and get
b = (c + 4 + c) - 3 = 2c + 4 - 3 = 2c + 1
abd we use the first and the second equation more in the third and get
c + 4 + 2c + 1 + c = 17
4c = 12
c = 3
b = 2c + 1 = 2×3 + 1 = 6 + 1 = 7
a = c + 4 = 3 + 4 = 7
so, the number is

Evaluate each function for the given value of x , and write the input x and output f(x) as an ordered pair.
f(x) = (7/3)x-9 for x=3
f (3) = -2 is the output for the given input .
How can you tell whether a function is linear or not?
Looking at a function's graph will reveal if it is linear or not with the greatest ease.When a linear function is plotted on a graph, a straight line is formed. A nonlinear function is curved in some way; it does not form a straight line.f(x)= (7/3)x- 9
Put x = 3 ⇒ 7 * 3/3 - 9
⇒ 7 - 9
⇒ -2
Therefore f (3) = -2

Explain the difference between finding the vertex of a function written in vertex form and finding the vertex of a function written in standard form.
The equation in the vertex form will be y = (x + b/2a)² - b²/4a² + c/a and the equation in the standard form will be ax² + bx + c = 0.
What is a quadratic equation?The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.
Convert the standard equation into a vertex form, then we have
x² + (b/a)x + (c/a) = 0
x² + (b/a)x + b²/4a² - b²/4a² + c/a = 0
(x + b/2a)² - b²/4a² + c/a = 0
Put h = - b/2a and k = - b²/4a² + c/a, where (h, k) be the vertex of the parabola. Then the equation will be
(x - h)² + k = 0
The function written in vertex form will be y = (x - h)² + k and in the standard form will be ax² + bx + c = 0.

Answer:
So to write this as an equation follow the steps:
1.First you take y delta divided by x delta. This means that you but in the coordinates, take them minus eachother then divided by eachother. Let me show you with maths for better understanding:
Now you have k in y=kx+m ( the equation has different letters depening on where you are from but I think you understand).
So know we just use simple algebra bu putting in the coordinates in the equation. So for this example im going to use the coordinates x= 8 and y=5
so we get:
Evaluate each expression for x=0 . 13-6.5 x
After evaluating the expression for x=0, the equation 13-6.5x = 13
⇒ 13-6.5(0)
⇒ 13 - 0
⇒ 13
How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

To Prove: ∠B and ∠C are complimentary
Proof :
step 1 : ∠A = 90°
step 2: According to angle-sum theorem
∠A + ∠B + ∠C = 180
step 3: 90 + ∠B + ∠C = 180

Answer:
3 hours
Step-by-step explanation:
[tex]speed = \frac{distance}{time} \\ 60 = \frac{d}{t} \\ d = 60t \\ \\ speed = \frac{distance}{time} \\ 40 = \frac{d}{t + 1} \\ d = 40(t + 1)[/tex]
Since;
[tex]d = 60t \: \: \: and\\ d = 40(t + 1) \\ [/tex]
Therefore;
[tex]60t = 40(t + 1) \\ 60t = 40t + 40 \\ 60t - 40t = 40 \\ 20t = 40[/tex]
Divide both sides by 20
[tex] \frac{20t}{20} = \frac{40}{20} \\ t = 2 \: hours[/tex]
Since the return trip took an hour longer to get back home an hour will be added to the time

Because the line PQ is perpendicular to line ST, the slope of line ST is -1
How to determine the slope of ST?The points are given as
P = (1, 4)
Q = (-2, 1)
Start by calculating the slope (m) of ST using
m = (y2 - y1)/(x2 - x1)
This gives
m = (1 - 4)/(-2 - 1)
Evaluate the difference
m = -3/-3
Evaluate the quotient
m = 1
From the question, we have
Line PQ is perpendicular to line ST
This means that
Slope of ST = -1/Slope of PQ
This gives
Slope of ST = -1/1
