anyone whos great at math?!?!?!?!!? the question is [tex]-x^2 -4xy+y^2 when x=-5 and y=-2[/tex]
I ALSO NEED TO SHOW MY WORKK PLAESEEEEE
Answer:
-19
Step-by-step explanation:
x= -5 y = -2
-x^2 - 4xy + y^2
- -5^2 -4(-5 x -2) -2^2 Plug in
+ 5^2 -4(-5 x -2) -2^2 Change the signs for - -5
5^2 - 2^2 - 4(10) Place Liked Terms together
25 - 4 - 40 Subtract

w=9
Answer:
Today: Friday, 06 November 2020
Hour: 19.17 WIB (Indonesia)
_______________________________
2 (w + 3) = -2(w - 21)
2w + 6 = -2w + 42
2w + 2w = -6 + 42
4w = 36
w = 9

Answer:
([tex]\frac{2}{3}[/tex], 2 )
Step-by-step explanation:
Given the 2 equations
3x + [tex]\frac{1}{2}[/tex] y = 3 → (1)
6x - y = 2 → (2)
Multiplying (1) by - 2 and adding to (2) eliminates the term in x, that is
- 6x - y = - 6 → (2)
Add (2) and (3) term by term to eliminate x
- 2y = - 4 ( divide both sides by - 2 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (2)
6x - 2 = 2 ( add 2 to both sides )
6x = 4 ( divide both sides by 6 )
x = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
Solution is ( [tex]\frac{2}{3}[/tex], 2 )
Solve the equation.
4n−18=5
Answer:
n = 5.75
Step-by-step explanation:
4(5.75) - 18 = 5
4(5.75) = 23
23 - 18 = 5
Therefore, n = 5.75.
Hope this helps:)

2 + 3( 4x + 5) = -53
Answer:
x=-35/6
Step-by-step explanation:
2 + 3( 4x + 5) = -53
subtract 2 from both sides= 3(4x+5)=-55
divide both sides by 3 = 4x+5=-55/3
subtract both sides by 5 = 4x=-70/3
divide both sides by 4 = x=-35/6
x=-35/6 is your final answer
Answer:
Hope this helps :)
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x=−35/6
Decimal Form:
x=−5.8¯3 (Repeating)
Mixed Number Form:
x=−5 5/6

Your friend, Broseph, recently graduated from the University of Bros. During his last semester he passed "Introduction to Brotistics with an Emphasis on Tinder Applications". His final project required that he use the Binomial Distribution to calculate the probability of going on a date with more than half of his next 20 Tinder matches.
Broseph found that he had a 64% chance of going on a date with any given Tinder match from historical data.
Broseph should use the ____________ to calculate the probability. Since he is calculating the probability of going on dates with more than half of his next 20 matches--the number of successes is ________ , n = ________ , and p = ______ .
Broseph has a __________ chance of going on dates with at least half of his next 20 Tinder matches. Round the answer to nearest tenth as a percentage i.e. 14.2%.
Answer:
I need to know the net percentage to to calculate the quadratic function

Bacteria doubles every 10 minutes. If you start with 2 bacteria in a petri dish, how many bacteria will there be after 40 minutes?
Answer: I think the answer is 32 bacteria after 40 minutes.
Step-by-step explanation:
I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

Answer:
-5/3
Step-by-step explanation:
Answer:
slope: -1.6666666
Step-by-step explanation:
Use the formula m=(y2-y1)/(x2-x1)
Substitute values: m=(13-8)/(6-9)
Solve that, and you will find m (slope) = -1.666666

For Spirit Day, each 8th-grade homeroom designs a unique twocolor T-shirt. They get to choose from the colors red (R), blue (B), green (G), violet (V), and orange (O). Each T-shirt is a solid color with a different color used for the student's name. What is the probability that a homeroom will have a T-shirt with a combination of blue and violet?
Answer:
P(B and V)=10%
Step-by-step explanation:To solve this poroblema we use the formula of combinations:
C(n,r)=(nr)=n!(r!(n−r)!)
Where n is the number of objects that can be chosen and you choose r from them.
There are 5 colors of shirts.
The number of shirts that can be made by combining 2 of the 5 possible colors is calculated as:
5C2= [tex]\frac{5!}{2!(5-2)!}[/tex]
5C2=10
The number of shirts that can be made by combining 2 of the 2 possible colors (B) and (V) is calculated as:
2C2=1
Then the probability is:
P( B and V)= [tex]\frac{1}{10}[/tex]
=0.1= 10%
[tex]\frac{2C2}{5C2}[/tex]
Answer:
P( B and V)=10%
