Answer:
y - 9 = -3/2 (x - 6)
Step-by-step explanation:
Equation of line: 4x - 6y - 15 = 0
Equation of perpendicular line: bx - ay + k = 0
= -6x - 4y + k = 0 → (equation 1)
Since the equation passes through (6,9)
-6(6) - 4(9) + k = 0
-36 -36 + k = 0
-72 + k = 0
k = 72
Substituting the value of in equation 1,
∴ Equation of perpendicular line = -6x -4y + 72 = 0
dividing by -2,
3x + 2y - 36 = 0
This equation is the simplified version of Option 1.
y - 9 = -3/2 (x - 6)
y - 9 = (-3x + 18)/2
2y - 18 = -3x + 18
3x + 2y - 36 = 0
Harriet is cultivating a strain of bacteria in a petri dish, she has 10^3 bacteria in the dish. The bacteria divided every two hours such that the number of bacteria has doubled by the end of every second hour. How many bacteria will Harriet have in the dish at the end of 6 hours?
Answer:
4000
Step-by-step explanation:
A=P(2)^(t/d)
A=future amount
P=starting amount
t=time elapsed
h=doubling time
given
P=10^3
t=6
d=2
A=10^3(2)^(6/2)
A=10^3(2)^2
A=10^3(4)
A=4*10^3
A=4000
4000 bacteria

Solve 3/4x+1/4y=5 for y
Answer:
y=3x+20
Step-by-step explanation:
So first, I don't like fractions so I would multiply the whole equation by 4. This will make the equation 3x+y=20. Then you have to isolate the y to find the answer so you should subtract 3x from both sides. This will make the equation look like this y=-3x+20. Therefore, y=3x+20
Solve for X (In the Diagram)

tell me 3 mathematical things that you know in relation to geometry
Answer:
Dilations which reduce or enlarge an object. Translations which move the object from one part on the graph to another. I have also learned about how to construct a perpendicular bisector.
Step-by-step explanation:
====================================
Geometry is a branch of mathematics that studies the sizes, shapes, positions angles and dimensions of things.====================================
--> Actually, Flat shapes like squares, circles, and triangles are a part of flat geometry and are called 2D shapes.
These shapes have only 2 dimensions, the length and the width.
( based on what i know )
What is the amplitude of the function f(x)= 6sin(3x)?
Answer:
6
Step-by-step explanation:
The function is of the form
y =a f(bx) where |a| is the amplitude and b is the frequency
y = 6 sin (3x)
The amplitude is |6| = 6
Change the subject from y to x
y = (2x + 1)/(3x + 4)
y(3x + 4) = (2x + 1)
3xy + 4y = 2x + 1
4y - 1 = 2x - 3xy
4y - 1 = x(2 - 3y)
x = (4y - 1)/(2 - 3y) , answer = E
f varies inversely as the square of d. When d=2, f = 6. Find d when f is 1.5
Answer:
d = 4
Step-by-step explanation:
Given f varies inversely as d² then the equation relating them is
f = [tex]\frac{k}{d^2}[/tex] ← k is the constant of variation
To find k use the condition when d = 2, f = 6 , then
6 = [tex]\frac{k}{2^2}[/tex] = [tex]\frac{k}{4}[/tex] ( multiply both sides by 4 )
24 = k
f = [tex]\frac{24}{d^2}[/tex] ← equation of variation
When f = 1.5 , then
1.5 = [tex]\frac{24}{d^2}[/tex] ( multiply both sides by d² )
1.5d² = 24 ( divide both sides by 1.5 )
d² = 16 ( take the square root of both sides )
d = [tex]\sqrt{16}[/tex] = 4
Solve each equation and check your answer.

M<1 and m<2 are vertical angles if m<1 = 106° and M<2 equals 20x - 14 find M<2
Answer:
Answer:
m∠2= 86
Step-by-step explanation:
since they are vertical angles, that means they are both equal to eachother.
so lets set them equal!
17x+1=20x-14
17x+15=20x
15=3x
x=5
now input x into m∠2
m∠2 = 20(5) – 14 = 86

How long is side c ?
Answer:
you do pythagorean theorem
Step-by-step explanation:
the base is 8 and the side length is 6 so you do 8²+6²
8²=64 +6²=36
64+36=100 you have to square 100 which is 10

I WILL GIVE BRAINLIEST!!!
Answer:
C
Step-by-step explanation:
The area is calculated as width × length , that is
[tex]\frac{50\sqrt{3} }{\sqrt{2} }[/tex] × [tex]\frac{80\sqrt{5} }{\sqrt{3} }[/tex] ( cancel [tex]\sqrt{3}[/tex] on numerator/ denominator
= [tex]\frac{50}{\sqrt{2} }[/tex] × 80[tex]\sqrt{5}[/tex]
= [tex]\frac{4000\sqrt{5} }{\sqrt{2} }[/tex]
To rationalise the denominator multiply numerator/denominator by [tex]\sqrt{2}[/tex]
= [tex]\frac{4000\sqrt{6} }{\sqrt{2} }[/tex] × [tex]\frac{\sqrt{2} }{\sqrt{2} }[/tex]
= [tex]\frac{4000\sqrt{10} }{2}[/tex]
= 2000[tex]\sqrt{10}[/tex] → C
Answer: The answer is C!

Write a real world problem for: 80-3x=53
Answer:
Sam had 80 dollars in his pocket. He was feeling generous, so he handed out equal amount of money to each of his friends. After he handed out the money, he had 53 dollars left. How much did Sam give out to each one of his friends?
Step-by-step explanation:
In this real-world problem, the money he had at the beginning resembles the 80 in the equation. The -3x is the money he gives out to each of his friends. The 53 on the right-hand side is the money he has left after he gives the money away.
In the last 4 seasons, Luis scored 14,18, 15, and 25 goals. How many goals does he need to score this year, to end the season with an overall average of 20 goals per season? O A. 29 O B. 27 O C. 30 O D. 28
Answer:
28
Step-by-step explanation:
For Luis to get a mean of 20 he would need:
14 + 18 + 15 + 25 + x (unknown number of goal he needs) / 5 = 20
Therefore 14 + 18 + 15 + 25 + x = 100
Solve for x to get 28
Trisha borrowed money from her mom to buy a skateboard plus safety gear. She paid back a little bit of money every week.

Write an equation in slope-intercept form to represent how much she owes her mom after x weeks.
y=
How much money is Trisha paying her mom each week? $
How long will it take Trisha to pay off her debt?
weeks (answer in whole weeks)
Answer:
y==$281+$166=$447
in 11 weeks she pay $ 447
in 1 weeks she pay $447/11=40.6$
she paid off in 3+8=11 weeks

What is the area of the trapezoid?
9 yd
8 yd
13 yd
Answer:
area = 88 yd²
Step-by-step explanation:
area = 1/2(b1 + b2)h = 1/2(9 + 13)(8) = 88 yd²
Answer:
88 yd^2.
Step-by-step explanation:
Area of a trapezoid = 1/2 * h * (a + b) where h = height, a and b are lengths of 2 parallel side.
Area = 1/2 * 8(9+13)
= 4 * 22
= 88 yd^2.
