Answer:
D. 31
Step-by-step explanation:
First Plug 2 into f(x) and solve.
You should get 22.
Then plug f(2) which is equal to 22 into g(x).
So, plug 22 into g(x).
You should get 31.
Twenty percent of a mixture of pure milk and water is water. Half a litre of wine is added to one litre of the mixture of water and milk and throughly mixed. What percentage of the new mixture is water?
Answer:
In the new mixture, the percentage of water with respect to its total is 13.33%.
Step-by-step explanation:
Given that in a liter of mixture 20% of it was water and the remaining 80% was pure milk, and that half a liter of wine was added to that liter of mixture, to determine the percentage of water in the new mixture is necessary to perform the following calculation:
20 + 80 + 50 = 150
150 = 100
20 = X
((20 x 100) / 150) = X
2,000 / 150 = X
13.33 = X
Thus, in the new mixture, the percentage of water with respect to its total is 13.33%.

If Z is the centroid of WXY, WR=87 SY=39 and YT=48 find each missing measure
Answer:
Step-by-step explanation:
WS=39
WY=78
WZ=58
ZR=29
ZT=16
YZ=32
The measures are WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Z is the centroid of triangle.
The centroid is the centre point of the object. The point in which the three medians of the triangle intersect is known as the centroid of a triangle.
WR=87 SY=39 and YT=48
We need to find WS,WY,WZ,ZR,ZT and YZ
WS=39
As WS=WR
WY=WS+SY
WY=39+39=78
WZ=58
ZR=WR-WZ
ZR=87-48=29
ZT=16
YZ=YT-ZT
=48-16=32
YZ=32
Hence, the measures are WS=39, WY=78, WZ=58, ZR=29, ZT=16 and YZ=32

What is the difference between the slope of a horizontal line and a vertical line?
Answer:
.
Step-by-step explanation:
The slope of a line is change in Y / change in X.
The slope of a horizontal line = 0, not undefined.
The slope of a vertical line = undefined.
Look at the system of equations in the box at
the right. Kevin stated that the equations in this system
have the same slope, so there will be infinitely many
solutions. Does Kevin's statement make sense?
Answer:
No.
Step-by-step explanation:
No, Kevin’s statement doesn’t make sense. He is correct that since the two equations have the same slope. Thus, they are parallel to each other.
However, since they are parallel, they will never touch. Therefore, there is no solution.
They will be infinitely many solutions if they are parallel and they have the same y-intercept.
Answer:
No it does not make sense
Step-by-step explanation:
If 2 linear equations have the same slope, then they represent two parallel linesParallel lines never cross, so they cannot have any solutionPlease help The profit P, of a fundraising event can be modeled by the equation p= 50x-2000, where x is the number of tickets sold. What does the 50 in this expression represents?
A. The number of tickets sold
B. The number of people that attended
C. The profit from the event
D. The cost per ticket
Answer:
D. The cost per ticket
Step-by-step explanation:
You might remember that an equation in the form [tex]y=mx+b[/tex] is in slope-intercept form, where m is the slope and b is any number constant.For this equation, [tex]p=50x-2000[/tex] , y is p, the slope m is 50 and b is -2000The slope tells how much the profit is changing with each ticketSlope simply means "the amount of change"So if we have 2 tickets sold, the profit is [tex]p=50*100-2000=3000[/tex] What about 101? [tex]p=50*101-2000=3050[/tex] So the profit is changing by 50 with every ticketThat means each ticket costs 50 whatever currency It will save you trouble to just remember that in a profit equation, the slope is always the cost per item.Select the correct answer.

Answer: Nonlinear; power of x is greater than 1 (Bottom right corner)
Explanation:
The equation y = x^2 - 1 is known as a quadratic since the largest exponent here is 2. This equation cannot be written in slope intercept form y = mx+b, so that's why it's not linear. You can also graph y = x^2-1 to get a curved parabola. The graph must be a straight line if you want a linear equation.

Quadrilateral ABDC, in which point F is between points A and C, point G is between points B and D, point I is between points A and B, and point H is between points C and D. A segment connects points A and D, a segment connects points B and C, a segment connects points I and H, and a segment connects points F and G. Segments AD, BC, FG, and IH all intersect at point E. ∠BEI ≅ ∠CEH because vertical angles are congruent; rotate ΔCEH 180° around point E, then translate point C to point B to confirm∠IBE ≅ HCE. ∠BEI ≅ ∠CEH because vertical angles are congruent; reflect ΔCEH across segment FG, then translate point C to point B to confirm∠IBE ≅ HCE. ∠BEI ≅ ∠CEH because vertical angles are congruent; rotate ΔCEH 180° around point E, then dilate ΔCEH to confirm segment EB ≅ segment EC. ∠BEI ≅ ∠CEH because vertical angles are congruent; reflect ΔCEH across segment FG, then dilate ΔCEH to confirm segment EH ≅ segment EI.
