Answer:
8x-9
Step-by-step explanation:
You have to combine like terms in order to simplify this problem.
The like terms you have are 5x, and 3x. If you add 5x+3x, you get 8x.
Now, you do nothing with the 9 because there is nothing to combine it with. For example, if your problem was 5x+3x-9+10, you combine 5x and 3x to get 8x, but now with the 9, you keep the subtraction symbol so it is 10-9, (think of it as -9), and when you finish that, you get 1. Now there are no more symbols so you add, 8x+1.

Determine the value of c such that f(x,y) = c(x 2y), x = 1, 2
The value of C is 0.03030 if the f(x, y) = c(x 2y), x = 1, 2 and y =1, 2, 3 because the sum of the probability is always 1
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
f(x, y) = c(x+2y),
x = 1, 2 and y =1, 2, 3
f(1, 1) = C(1 + 2) = 3C
f(1, 2) = C(1 + 4) = 5C
f(1, 3) = C(1 + 6) = 7C
f(2, 1) = C(2 + 2) = 4C
f(2, 2) = C(2+ 4) = 6C
f(2, 3) = C(2 + 6) = 8C
We know the sum of the all probability is 1
3C+5C+7C+4C+6C+8C=1
33C =1
C = 0.03030
Thus, the value of C is 0.03030 if the f(x, y) = c(x 2y), x = 1, 2 and y =1, 2, 3 because the sum of the probability is always 1

A triangle has one angle that measures 50° and one angle that measures 40°.
What kind of triangle is it?
A.isosceles triangle
B.obtuse triangle
C.right triangle
D.equiangular triangle
Answer:
Right triangle
Step-by-step explanation:
If the triangle has one angle that measures 50 degrees and another angle that measures 40 degrees, then the last angle must measure 90 degrees because the 3 angles of any triangle add up to 180, so we can set up the following:
180 - (50 + 40) = 90 degrees.
Any triangle that has a 90 degree angle is automatically a right triangle.
Hope this helps!
________________________________________________________
Option AAs we know, a triangle has 180° in total and has three angles.
⇒ Angle 1 + Angle 2 + Angle 3 = 180
We are given the following:
1st angle = 50°2nd angle = 40°Let the 3rd angle be known as "x".
For the triangle to be classified as an isoceles triangle, two angles must be of same measure. Thus, there are two possibilities.
⇒ 50 + 40 + 40 = 180 [Angle 2 = Angle 3]
-------------- Or -------------
⇒ 50 + 40 + 50 = 180 [Angle 1 = Angle 3]
Possibility-1:
⇒ 50 + 40 + 40 = 180⇒ 50 + 80 = 180⇒ 130 = 180 (False)Possibility-2:
⇒ 50 + 40 + 50 = 180 ⇒ 100 + 40 = 180 ⇒ 140 = 180 (False)Therefore, the triangle cannot be an isoceles triangle.
________________________________________________________
Option BAs we know, a triangle has 180° in total and has three angles.
⇒ Angle 1 + Angle 2 + Angle 3 = 180
We are given the following:
1st angle = 50°2nd angle = 40°Let the 3rd angle be known as "x".
For the triangle to be classified as an obtuse triangle, the third angle must be a measure greater than 90°. Therefore,
⇒ 50 + 40 + (x > 90) = 180⇒ 90 + (x > 90) = 180⇒ (x > 90) = 180 - 90⇒ (x > 90) = 90 (False)This is false because 90 is not greater than 90. Therefore, the triangle is not an obtuse triangle.
________________________________________________________
Option CAs we know, a triangle has 180° in total and has three angles.
⇒ Angle 1 + Angle 2 + Angle 3 = 180
We are given the following:
1st angle = 50°2nd angle = 40°Let the 3rd angle be known as "x".
For the triangle to be classified as a right triangle, the third angle must be a measure equivalent to 90°. Therefore,
⇒ 50 + 40 + 90 = 180⇒ 90 + 90 = 180⇒ 180 = 180 (True)Therefore, this triangle is a right triangle.
________________________________________________________
Option DAs we know, a triangle has 180° in total and has three angles.
⇒ Angle 1 + Angle 2 + Angle 3 = 180
We are given the following:
1st angle = 50°2nd angle = 40°Let the 3rd angle be known as "x".
For the triangle to be classified as an equiangular triangle, all the angles must be equivalent (60°). Therefore,
⇒ 1st angle = 2nd angle = 3rd angle⇒ 50 = 40 = 3rd angle (False, because 50 is not equivalent to 40)Therefore, this triangle is not an equiangular triangle.
________________________________________________________
In conclusion, we can conclude that Option C (Right triangle) is correct.

Having trouble with this. Find the measure of the following arcs or angles.
The missing angle ∠APB, angle ∠CPD, and angle ∠EPA will be 65°, 77°, and 77° respectively.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
The diagram is given below.
The angle ∠BPC is 38° and the angle ∠DPE is 103°.
Then the missing angle will be
Angle ∠CPD and angle ∠DPE are linear angles. Then we have
∠CPD + ∠DPE = 180°
∠CPD + 103° = 180°
∠CPD = 77°
Similarly, angle ∠APB, angle ∠BPC, and angle ∠CPD are linear angles. Then we have
∠APB + ∠BPC + ∠CPD = 180°
∠APB + 38° + 77° = 180°
∠APB = 65°
Then the complete circle makes 360°. Then we have
∠APB = 360° - 65° - 38° - 77° - 103°
∠APB = 77°

I also saw an answer that didn't put any method/calculations. I NEED to put the method there otherwise my teacher will think I cheated and I will not be able answer questions like this in the future.
Answer:
Extremely sorry if my answer is wrong or doesn't make sense! Also sorry that I couldn't solve it farther, I solved it using sense and haven't made it this far in math!
Step-by-step explanation:
If red is 2:3 then that means red to green is either 2:2 or 2:1. Same goes with blue.
If green is 6:19 then we can figure out the 2 possibilities for red to green.
First Possibility:
If the red to green ratio is 2:2, then the red to green to blue is 6:6:13 because 6 + 19 - 12 = 13.
Second Possibility:
If the red to green ratio is 2:3, then the red to green to blue ratio is 4:6:15 because 6 + 19 - 10 = 15.

Give your answer as a decimal.
Answer:
.093
Step-by-step explanation:
do
1.00-0.07
the probability that the light bulb will still be working after 1000 hours of use is 0.93 (or 93%).
To find the probability that the light bulb will still be working after 1000 hours of use, we can use the fact that the sum of the probabilities of all possible outcomes must be equal to 1.
Given that the probability of the light bulb failing after 1000 hours of use is 0.07, the probability of it still working after 1000 hours is:
Probability of the light bulb working after 1000 hours = 1 - Probability of the light bulb failing after 1000 hours
Probability of the light bulb working after 1000 hours = 1 - 0.07
Probability of the light bulb working after 1000 hours = 0.93
So, the probability that the light bulb will still be working after 1000 hours of use is 0.93 (or 93%).

a) $49,000
b)$75,000
c)-49,000
d)$125,000
Answer:
The answer is a.) $49,000
Step-by-step explanation:
i just took the test!!
Given that the company estimates the probability that the new can opener will be will be successful is 5/8. If it is successful, it would be able to make $200,000. The company would make nothing if it were unsuccessful. The development costs for the can opener are $76,000. The expected value is $49000.
What is expected value?Expected value is the return you can expect for some kind of action.
The formula for the Expected Value is: ΣX.P(X) .
The amount earned by the company if the new can opener is successful = Revenue of the company - amount invested = $200,000 - $76,000 = $124,000
Probability that the new can opener will be successful = 5/8
Amount earned/ lost if the new can opener is not successful = $0
Probability that the new can opener will not be successful = 1 – 5/8 = 3/8
Expected value = amount earned if the new can opener is successful * Probability that the new can opener will be successful + Amount earned/ lost if the new can opener is not successful * Probability that the new can opener will not be successful
= 124,000 * 5/8 + 0 * 3/8

Write the equation of a circle with a radius of length 10 and a center at (-4, -9).
Answer choices in attached image
Answer:
(x+4)² + (y+9)² = 100
Step-by-step explanation:
We want to find the equation of a circle with a radius of length 10 and a center at (-4, -9).
general equation of circle : (x-h)² + (y-k)² = r²
where (h,k) is at center and r = radius
the center is at (-4,-9) so h = -4 and k = -9 and the circle has a radius of 10 so r = 10
so we have (x-h)² + (y-k)² = r²
h = -4 , k = -9 and r = 10
(x-(-4))² + (y-(-9))² = 10²
==> apply double negative sign rule and remove parenthesis for -(-4) and -(-9)
(x+4)² + (y+9)² = 10²
==> simplify exponent
(x+4)² + (y+9)² = 100
and we are done!
Answer:
Option D
Step-by-step explanation:
Given:
Radius = 10 unitsCenter point = (h, k) = (-4, -9)∴ x coordinate of center point: (h, k) ⇒ (-4, -9)
∴ y coordinate of center point: (h, k) ⇒ (-4, -9)
Equation of circle formula:
⇒ (x - h)² + (y - k)² = r²Substitute the radius in the formula;
⇒ (x - h)² + (y - k)² = r²⇒ (x - h)² + (y - k)² = (10)²Substitute the x and y coordinate in the formula;
⇒ [x - (-4)]² + [y - (-9)]² = (10)² [x coordinate (h): -4; y coordinate (k): -9]⇒ [x + 4]² + [y + 9]² = 100 (Option D)Therefore, Option D is correct.
