A person can pay $11 for a membership to the art museum and then go to the museum for just $5 per visit. What is the maximum number of visits a member of the art museum can make for a total cost of $31?
Answer In the number of visits. (Step by step if you could please I’m doing this IXL having no idea how to do these)
Answer:
4 visits.
Step-by-step explanation:
First make an equation to represent the cost of the museum stuff using the formula y=mx+b
y=5x+11 would be the formula because you pay a flat fee of $11 for the membership and $5 for each visit after (x represents visits, y represents total cost)
Now we need to figure out how many visits a bill of $31 would represent.
We plug in 31 for y because y represents the total cost.
31=5x+11
Now solve for x.
Subtract 11 from both sides: 20=5x
Divide each side by 5: 4=x
Since x=4, it means that a bill of $31 would represent four visits.
Answer:
The maximum number of visits a member of the art museum can make for a total cost of $31 is 4 visits.
Step-by-step explanation:
Since the person must pay a membership fee of $11, we can deduct $11 from the total cost of $31.
$31 - $11 = $20
Now, we have $20 left to max out. Since each visit to the art museum is $5 per visit, we can divide 20 by 5.
$20 / $5 = 4
So the answer must be the person can make 4 maximum visits (and buy a membership) to equal $31. Hope this helps.

Given that triangle ABC ~ triangle DEF, solve for x and y
The value of x and y are 42/5 and 55/6 after using the property of a similar triangle.
What is the similarity law for triangles?It is defined as the law to prove that the two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
We have two triangles shown in the picture.
By using the property of a similar triangle:
y/7 = 11/x = 6/5
y/7 = 6/5
y = 42/5
11/x = 6/5
x = 55/6
Thus, the value of x and y are 42/5 and 55/6 after using the property of a similar triangle.

What is the equation of the parabola passing through the points 2,3 , 6,9and 8,0?
Answers:
-1 in the first box19/2 or 9.5 in the second box-12 in the third box=================================================
Work Shown:
We'll use the template y = ax^2 + bx + c
If (x,y) = (2,3) is on the parabola, then y = ax^2+bx+c turns into 3 = a(2)^2 + b(2) + c. That simplifies to 4a+2b+c = 3If (x,y) = (6,9) is on the parabola, then y = ax^2+bx+c turns into 9 = a(6)^2 + b(6) + c. That simplifies to 36a+6b+c = 9If (x,y) = (8,0) is on the parabola, then y = ax^2+bx+c turns into 0 = a(8)^2 + b(8) + c. That simplifies to 64a+8b+c = 0The system of equations is
[tex]\begin{cases}4a+2b+c = 3\\36a+6b+c = 9\\64a+8b+c = 0\end{cases}[/tex]
We have 3 equations and 3 unknowns.
-----------------------------------
Let's solve the first equation for c
4a+2b+c = 3
2b+c = 3-4a
c = 3-4a-2b
c = -4a-2b+3
Plug that into the second equation and simplify
36a+6b+c = 9
36a+6b+(-4a-2b+3) = 9
32a+4b+3 = 9
32a+4b = 9-3
32a+4b = 6
2(16a+2b) = 6
16a+2b = 6/2
16a+2b = 3 .... we'll use this later
Plug that value of c into the third equation as well
64a+8b+c = 0
64a+8b+(-4a-2b+3) = 0
60a+6b+3 = 0
3(20a+2b+1) = 0
20a+2b+1 = 0
20a+2b = -1
--------------------------
We have a new system of equations. This time it deals with 2 variables instead of 3. We can think of this as a reduced equivalent system.
[tex]\begin{cases}16a+2b = 3\\20a+2b = -1\end{cases}[/tex]
Note how subtracting the terms straight down has the b terms canceling (since 2b-2b = 0b = 0)
The 'a' terms subtract to 16a-20a = -4a
The terms on the right hand side subtract to 3-(-1) = 3+1 = 4
We end up with the equation -4a = 4 which solves to a = -1
Use this value of 'a' to find b
16a+2b = 3
16(-1)+2b = 3
-16+2b = 3
2b = 3+16
2b = 19
b = 19/2
b = 9.5
Now use the values of a and b to find c
4a+2b+c = 3
4(-1)+2(9.5)+c = 3
-4+19+c = 3
15+c = 3
c = 3-15
c = -12
--------------------------
Summary:
The values of a,b,c we found were
a = -1b = 19/2 = 9.5c = -12So the function is
f(x) = -x^2 + (19/2)x - 12
which is equivalent to
f(x) = -x^2 + 9.5x - 12
To check this answer, plug in x = 2, x = 6, x = 8 one at a time. You should get y = 3, y = 9 and y = 0 in that order.
Answer:
f(x)=-x^2+9.5-12

Answer:
The resulting function is [tex]g(x) = \log_{2} (x+5)-4[/tex].
Step-by-step explanation:
Let [tex]f(x)[/tex] a real function, we define the following function operations:
Horizontal translation
[tex]g(x) = f(x + a)[/tex] (1)
If [tex]a > 0[/tex], then horizontal translation is to the left, otherwise it is to the right.
Vertical translation
[tex]g(x) = f(x) + a[/tex] (2)
If [tex]a> 0[/tex], then vertical translation is upwards, otherwise it is downwards.
Knowing that [tex]f(x) = \log_{2}x[/tex] and [tex]g(x)[/tex] is the result of translating [tex]f(x)[/tex] four units downwards and five units to the left. Then, we find that:
[tex]g(x) = \log_{2} (x+5)-4[/tex]
The resulting function is [tex]g(x) = \log_{2} (x+5)-4[/tex].

Step-by-step explanation:
The altitude of the triangle must equal 4 because it is a right triangle with another leg of 3 and a hypotenuse of 5 (reason is due to the pythagorean theorem)
Therefore, the triangle on the right has legs of 4 and 7 and, again, use the phythagorean theorem to find 'x' (the hypotenuse)
[tex]4^{2}[/tex] + [tex]7^{2}[/tex] = [tex]x^{2}[/tex]
16 + 49 = [tex]x^{2}[/tex]

Dilate the figure by a scale factor 1/2 of with the origin as the center of Gilation. What are the coordinates of the image ABC?
Answer:
The coordinates of the image ABC will be:
A'(3, 3)B'(6, 6)C'(15, 12)Step-by-step explanation:
Given the vertices of an original triangle
A(6, 6)B(12, 12)C(30, 24)We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlarged
If the scale factor is between 0 and 1, it gets shrunk
If the scale factor = 1, the object and the image are congruent
Rule to calculate the dilation by a scale factor 1/2 centered at the origin
P(x, y) → P'(1/2x, 1/2y)
so
A(6, 6) → A'(1/2(6), 1/2(6)) → A'(3, 3)
B(12, 12) → B'(1/2(12), 1/2(12)) → B'(6, 6)
C(30, 24) → C'(1/2(30), 1/2(24)) → C'(15, 12)
Therefore, the coordinates of the image ABC will be:

Answer:
18000ml or you an also say 18000[tex]cm^{2}[/tex] and 18 [tex]dm^{2}[/tex]
Step-by-step explanation:
In order to solve this question we will just have to multiply the current volume of the water by 1000. So we get....
18 x 1000 = 18000ml
If you will need to give the answer in [tex]cm^{2}[/tex] or in [tex]dm^{2}[/tex], then if we know that [tex]1ml = 1cm^{2}[/tex]. We can say that the volume of 18 ml of water is equal to.....
18000ml = 18000[tex]cm^{2}[/tex]
18000ml = 18 [tex]dm^{2}[/tex]
If J is the centroid of CDE, DE=52, FC=15, and HE= 14, find each missing measure
Answer:
DG = 26
GE = 26
DF = 15
CH = 14
CE = 28
Step-by-step explanation:
Find the image attached for the complete question
IF If J is the centroid of CDE, this means that J divides CG, FE, DC, CE and DH into two equal parts.
The following expressions are therefore true
DG + GE = DE and DG = GE
Substituting
DG + DG = DE
2DG = DE
Given DE - 52
2DG = 52
DG = 52/2
DG = 26
Since DG = GE, hence GE = 26
Also DF + FC = DC and DF = FC
Since FC = 15, hence DF = 15
Also CH + HE = CE and CH = HE
Since HE = 14, hence CH = 14
CE = 14+14
CE = 28
DG = 26, GE = 26, DF = 15, CH = 14, CE = 28
IF If J is the centroid of CDE, this means that J divides CG, FE, DC, CE and DH into two equal parts
Therefore,
DG + GE = DE ....(1)
DG = GE ...(2)
Substituting (2) in (1) ,we get
DG + DG = DE
2DG = DE
Also, DE = 52 (Given)
So, 2DG = 52
DG = 26
As, DG = GE,
Therefore, GE = 26
Also, DF + FC = DC and DF = FC
As, FC = 15,
So, DF = 15
Also CH + HE = CE and CH = HE
Since HE = 14,
So, CH = 14
CE = 14+14=28
So, CE = 28
Therefore, DG = 26 , GE = 26, DF = 15, CH = 14, CE = 28
