Answer:
f(2) = -5
Step-by-step explanation:
For this problem, we are evaluating the graph of f(x), meaning at the value of x, we want the y-value.
Note, when x = 2 on the graph, the only y coordinate available is y = -5.
Hence, when we evaluate f(x) for x = 2, we get y = -5. f(2) = -5.
Cheers.

if x+y=2, calculate:
P=4x (x-3)+4y(y-3)+8xy
Answers
Answer:
Step-by-step explanation:
P = 4x(x - 3) + 4y(y - 3) + 8xy
= 4x² - 12x + 4y² - 12y + 8xy
= (4x² + 8xy + 4y²) - (12x + 12y)
= 4(x² + 2xy + y²) - 12(x + y)
= 4(x + y)² - 12(x + y)
x+y =2 ⇒ P = 4.2² - 12.2 = 16 - 24 = -8

richard is walking around his neighborhood. if he walks 1/3 mile in 1/6 hour, how fast is richard walking, in miles per hour?
Answers
Answer:
2 miles per hours
Step-by-step explanation:
You divide 1/3 mile by 1/6 hour
Use the reciprocal.
1/3 x 6/1 = 2/1
Simplify
2/1 = 2
You can also solve it this way:
If 1/6 hour is 10 minutes, and it takes 10 minutes to walk 1/3 a mile, then it would take 30 minutes to walk a mile.
30 x 2 = 60
Either way, Richard walks 2 miles per hour.
Richard is walking at an average speed of 2 miles per hour which is the correct answer would be option (B).
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
To determine how fast is Richard walking, in miles per hour
We have to calculate the average speed which is the ratio of the total distance traveled by a body to the total time
Total distance traveled by Richard = 1/3 mile
The total time taken = 1/6 hour
Average speed = the total distance / the total time
Average speed = (1/3) / (1/6)
Reciprocal the denominator term, and we get
Average speed = (1/3) × 6
Average speed = 2 miles per hour
Therefore, he is at an average speed of 2 miles per hour

Answers
Answer:
x = 2

Step-by-step explanation:
set the top and bottom equations equal to each other...
5x + 77 = 9x + 69, solve for x...
subtract 69 and 5x from both sides...
8 = 4x
divide both sides by 4...
x = 2
substitute 2 for x in either equation...
5(2) + 77 = 87°
subtract 87 from 180...
180° - 87° = 93°
z = 93°

i’ll try to break it down for u so u can understand a little better.
the horizontal line is X and the vertical line is Y.
if u start in the middle going horizontally to the right u can find X and X will = 2
to find Y u need to start in the middle and count upwards until you find where the lines meet to create a point. Y = 1
X/Y = 2/1 which can simplify to 2
But since the line is going from left to right and going downwards it is negative hope this helped :)
You go shopping at a local department store with your friend and cousin. You buy one pair of jeans, four pairs of shorts, and two shirts for $84. Your friend buys two pairs of jeans, one pair of shorts and three shirts for $76. Your cousin buys one pair of jeans, two pairs of shorts and one shirt for $52. Find the cost of one pair of shorts.
Answers
Answer:
So, cost of 1 pair of shorts =$12
Step-by-step explanation:
Let cost of 1 pair of jeans =x
Cost 1pair of shorts =y
cost of 1 pair of shirts=z
We can set up equations as
x+4 y+2 z=84
2 x+1 y+3 z=76
x+2 y+z=52
Solve the equations for y.
Take first and second equations multiply first equation by -2 and add it with second equation.
-2 x-8 y-4 z=-168
2 x+1 y+3 z=76
Add them, it gives -7 y-z =-92
Now, take second and third equations, multiply the third equation by -2 then add them together.
2 x +1 y +3 z =76
-2 x-4 y-2 z=-104
Add them together,
-3 y +z =-28
Now, take the -7 y -z =-92 and -3 y +z =-28
Add the equations
-10 y = -120
Divide both sides by -10
y =12.
So, cost of 1 pair of shorts =$12
z=8

However, we already know the hypotenuse and one leg. Therefore we can substitute inside the equation to find the missing value.

Rosa has $117 in her savings account and $95 in her checking account. Each week she will put $21 into her savings account and $25 into her checking account. Complete the equation that can be used to find the number of weeks, x, until Rosa has the same amount of money in both accounts.
Answers
Answer:
It will take Rosa 5 and a half (5.5) weeks to have the same amount of money in both accounts.
Step-by-step explanation:
For this problem, we will have to set two expressions equal to each other. The first expression will represent Rosa's saving account, which already has $117 in it. Every week ([tex]x[/tex]), she adds $21 to her savings account:
[tex]21x+117[/tex]
The second expression will represent Rosa's checking account. Rosa's checking account already has $95 in it. Every week ([tex]x[/tex]), she adds $25 to her checking account:
[tex]25x+95[/tex]
Now that we have our two expressions, set them equal to each other. This is our equation that will be used to find the number of weeks ([tex]x[/tex]) it takes until Rosha has the same amount of money in both accounts:
[tex]21x+117=25x+95[/tex]
Subtract [tex]21x[/tex] from both sides of the equation:
[tex]117=4x+95[/tex]
Subtract [tex]95[/tex] from both sides of the equation:
[tex]22=4x[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]4[/tex]:
[tex]5.5=x[/tex]
[tex]x=5.5[/tex]
So it will take five and a half weeks for her accounts to have the same amount of money.
_
Check your work by substituting [tex]5.5[/tex] into the initial equation:
[tex]21(5.5)+117=25(5.5)+95[/tex]
[tex]115.5+117=137.5+95[/tex]
[tex]232.5=232.5[/tex]
Since the accounts have the same amount, the answer is correct!
Answer:
5.5 weeksStep-by-step explanation:
GivenInitial balance
Savings account = $117Checking account = $95Added amount per week
Savings account = $21Checking account = $25If number of weeks is x, then required equation is
117 + 21x = 95 + 25xSolving for x
25x - 21x = 117 - 954x = 22x = 22/4x = 5.5The answer is 5.5 weeks
