Answer:
y=-1/3x-6
Step-by-step explanation:
Perpendicular lines have slopes that are negative and reciprocal; if you multiply them together, the result is -1
so, to find the slope of the new line:
3m=-1
divide by 3
m=-1/3
the slope of the new line is -1/3
Slope-intercept form is written as y=mx+b, where m is the slope and b is the y intercept.
Here's our equation so far:
y=-1/3x+b
since the line passes through the point (9,-9), we can use it to solve for b
substitute into the equation:
-9=-1/3(9)+b
-9=-3+b
-6=b
b is -6
here's our equation
y=-1/3x-6
hope this helps! :D

i need help solving the paint questions
For S if the ratio is 2:7 and you use 20 drops of red paint you multiply 2 by 10 which is 20 so you also multiply 7 by ten to get 70 (So the answer for S is 70 drops) and for L you multiply 2 by 20 to get 40 so you multiply 7 by 20 and you get 140 (The answer for L is 140 drops) For T you multiply 2 by 1.5 to get 3 so you multiply 7 by 1.5 which is 10.5 ( so the answer for T is 10.5 drops)
Lisa and Maria were baking oatmeal cookies. Lisa baked 24 cookies on Friday and 36 on Saturday. Maria baked the same amount of cookies that Lisa baked on Saturday. How many cookies did they bake altogether?
Answer:
96 cookies.
Step-by-step explanation:
I don't love the wording of the question, but here's what I see:
Lisa Friday: 24
Lisa Saturday: 36
Maria total: 36
Cookie total: 96
-----------------------------------------------------
I can't really tell from how the question is worded if Maria's total was the total of what Lisa made, and she did it all on Saturday, or if Maria baked Lisa's Saturday number of cookies.
If 96 is the wrong answer, then try:
Lisa Friday: 24
Lisa Saturday: 36
Maria total: 60
Cookie total: 120

Step-by-step explanation:
An even number is divisible by 2.
if - then :
hypothesis:
conclusion:
Answer:
A logical sentence is written as:
If P, then Q.
Where:
P = hypothesis
Q = conclusion.
For this particular case, we know that a number is even only if the number is divisible by 2.
Then we can write:
if a number is divisible by 2, then it is an even number.
Here we have:
hypothesis = a number is divisible by 2.
conclusion = the number even.
There is a 0.9987 probability that a randomly selected 31-year-old male lives through the year. A life insurance company charges $186 for insuring that the male will live through the year. If the male does not survive the year, the policy pays out $100,000 as a death benefit. Complete parts (a) through (c) below.
Parts a through c is missing and it is;
a) From the perspective of the 33-year-old male, what are the monetary values corresponding to the two events of surving the year and not surviving?
The value corresponding to surviving the year is $_____.
The value corresponding to not surviving the year is $_____.
b) If the 33-year-old male purchases the policy, what is his expected value?
The expected value is $_____.
c) Can the insurance company expect to make a profit from many such policies? Why?
_____ because the insurance company expects to make an average profit of $_____ on every 33-year-old male it insures for 1 year.
Answer:
A) the value that corresponds to surviving the year = - $186
The value corresponding to not surviving the year = $99814
B) μ = -$56
C) Yes, the company can make a profit from many such policies because it makes an average profit of $56 on every 31 year old male it insures for 1 year.
Step-by-step explanation:
A) The company charges $186 for insuring. Thus;
Amount paid out = - $186
Therefore, the value that corresponds to surviving the year = - $186
Therefore, the value corresponding to not surviving the year = $100000 - $186
The value corresponding to not surviving the year = $99814
B) since probability that a 31 year old male survives is 0.9987, then;
Probability that a male doesn't survive is;
P(doesn't survive) = 1 - 0.9987
P(doesn't survive) = 0.0013
The expected value is calculated from;
μ = Σx•P(x) = (0.0013 × 99814) + (-186 × 0.9987)
μ = -$56
C) Yes, the company can make a profit from many such policies because it makes an average profit of $56 on every 31 year old male it insures for 1 year.

Answer and Step-by-step explanation:
We know that the triangle got dilated by a scale factor of 4. This means that the sides are multiplied by 4.
So 6 becomes 24, and 8 becomes 32.
Now, we find the area of the triangle.
24 × 32 = 768
768 ÷ 2 = 384.
The answer is D. 384 square cm.
The answer IS NOT B. 96 square cm, because you don't multiply the area of the triangle before the dilation. The dilation occurs first, and then you have to find the area.

Suppose a book has been on a desk 1 m above the floor. A student accidentally knocks the book off of the desk and it falls to the floor. During this process, ___________ energy has been changed into _______ energy.
Answer: Potential; Kinetic
Step-by-step explanation:
''...During this process, potential energy has been changed into kinetic energy.''
Potential energy is the energy that a stationery object has because it is stored within the object. In this case the object is the book.
When an object begins to move, it gains kinetic energy which is converted from its potential energy. As the book falls to the floor in this scenario, it gained kinetic energy as its potential energy was converted to enable it move.

Answer:
[tex]\frac{(x + 1)(x - 2)}{x^{2} + 5}[/tex] This is the third option.
Step-by-step explanation:
Dividing a fraction is the same as multiplying the reciprocal of the second fraction.
[tex]\frac{x + 1}{x + 4}[/tex] × [tex]\frac{(x + 4)(x - 2)}{x^{2} + 5}[/tex]
[tex]\frac{(x + 1)(x + 4)(x - 2)}{(x + 4)(x^{2} + 5)}[/tex] Here, we can just get rid of the (x + 4) because it is common in both the numerator and denominator so they cancel each other out.
So the answer would be [tex]\frac{(x + 1)(x - 2)}{(x^{2} + 5)}[/tex] .
I hope this makes sense!! ^-^

help me find the solution
Answer:
Step-by-step explanation:
\[2~ sin^2 x+3sin x+1=0\]
\[2sin^2x+2sin x+sin x+1=0\]
2sinx(sin x+1)+1(sin x+1)=0
(sin x+1)(2 sin x+1)=0
either sin x+1=0
sin x=-1=sin 3π/2=sin (2nπ+3π/2)
x=2nπ+3π/2,where n is an integer.
or 2sin x+1=0
sin x=-1/2=-sin π/6=sin (π+π/6),sin (2π-π/6)=sin (2nπ+7π/6),sin (2nπ+11π/6)
x=2nπ+7π/6,2nπ+11π/6,
where n is an integer.

Answer:
Step-by-step explanation:
By the Pythagorean Theorem we know
h^2=x^2+y^2 (where h is the hypotenuse and x and y are sides of a right triangle)
w^2+18^2=30^2
w^2=30^2-18^2

A cash withdrawal of R5000 was made at signet blue on the 20/05/2019.Calculate what percentage the withdrawal fee is of the transaction amount
Answer: 1%
Step-by-step explanation:
Question is incomplete as it lacks the details of the withdrawal fee.
We shall assume one so that we can use it for calculation so that you can understand the methods.
Assume withdrawal fee of R50.
The withdrawal amount was R5,000 and the cost to withdraw was R50.
The percentage of the withdrawal fee in relation to the total amount is:
= Withdrawal amount / Total amount * 100%
= 50 / 5,000 * 100%
= 1%
