Mrs. Becker is selling tickets to an art exhibit, but she lost the receipts. She knows that she has sold at least 20 tickets. The adult tickets (x) cost $14 and the children’s tickets (y) cost $12. If she knows she has sold no more than $420 worth of tickets, write a system of inequalities to model the ticket sales.

Answer:

84

Step-by-step explanation:

To get from 4 to 12, you multiply with 3.

Everything is 3 times as big in the larger rectangle.

This includes the perimeter.

Example:

small rect 4x10, perimeter 4+4+10+10 = 28

large rect 12x30, perimeter 12+12+30+30 = 84

but also 28x3 = 84

The perimeter of the larger rectangle is 84.

Its the sum of length of the sides used to made the given figure.

We are given that length of small rectangle is 4 and the length of the big

rectangle is 12. If the perimeter of the smaller rectangle is 28,

The small rectangle

length = 4

perimeter = 28

The big rectangle

length = 12

perimeter = ?

The small rectangle perimeter = 2l + 2w

28 = 2 * 4 + 2 w

28 - 8 = 2w

20 / 2 = w

10 = w

The big rectangle perimeter;

4 w = 10 * 12

w = 120 / 4 = 30

Perimeter = 2*12 + 2*30

= 24 + 60 = 84

The perimeter of the big rectangle is 84.

Answer:

2x2−3y2=6or2x26−3y26=1 or. x23−y22=1or(x−0)2(√3)2−(y−0)2(√2)2=1. This is standard form of the equation of a hyperbola with center.

Step-by-step explanation:

c2 = a2 + b2. Every hyperbola has two asymptotes. A hyperbola with a horizontal transverse axis and center at (h, k) has one asymptote with equation y = k + (x - h) and the other with equation y = k - (x - h).

The slopes of the asymptotes of the hyperbola are +3 and -3.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

The standard equation for a hyperbola with a horizontal transverse axis is:

[tex](x-h)^2/a^2 - (y-k)^2/b^2 = 1[/tex]

where (h,k) is the center of the hyperbola, "a" is the distance from the center to the vertices along the x-axis, and "b" is the distance from the center to the vertices along the y-axis.

Comparing this to the given equation:

[tex]x^2/2^2 - y^2/6^2 = 1[/tex]

We can see that h = k = 0, a = 2, and b = 6.

The slopes of the asymptotes are given by:

±(b/a)

So, the slopes of the asymptotes are:

±(6/2) = ±3

Therefore,

The slopes of the asymptotes of the hyperbola are +3 and -3.

[tex]\mathrm{The\:three\: integers\: are\: 11, 12, \: and\:13.}[/tex]

Step-by-step explanation:

We can set up the following equation with the information given:

[tex](x-1)+x+(x+1)=4x-12[/tex], where [tex]x[/tex] is the middle integer.

Solving, we get:

[tex]3x=4x-12, \\-x=-12,\\x=\fbox{12}[/tex].

The three consecutive integers which are 12 less than 4 times the middle integer are 11, 12, and 13.

Integers consist of whole numbers and negative numbers on a number line. For e.g -17, 2, 0, etc. are integers.

Consecutive integers mean integers that come one after another in the number line like 1, 2, 3 or 10, 11, 12, etc.

So if we have to form an equation for three consecutive numbers, it will,

(x-1), x, (x+1),

Now, according to the question,

(x-1) + x + (x+1) =  4x -12

Solve the equation,

3x = 4x -12

x = 12

Hence, first integer = 12 -1 = 11,

Second integer = 12,

Third integer = 12+1 = 13.

Therefore, the three consecutive integers which are 12 less than 4 times the middle integer are 11, 12, and 13.

16(1/4)^2 - 4(6)

16(1/16) - 24

1 - 24 = -23

Step-by-step explanation:

We find the equation of the solid blue line:

The line decreases by 1 unit for every 3 units across.

=> Slope of line = -1/3.

Also the y-intercept is 1.

=> Line equation: y = -1/3 x + 1.

We see that the graph below this line is shaded.

Therefore all y-values below or on the line are represented by the graph.

=> y <= -1/3 x + 1.

The answer is y <= -1/3 x + 1.

y=5/3x+b

-7=5/3(-4)+b

The equation of a line passing through the points (-4,-7) and (8,-13) will be x + 2y + 18 = 0.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

The given points are (-4,-7) and (8,-13).

Then the equation of a line passing through the points (-4,-7) and (8,-13) will be

[tex]\begin{aligned} y + 13 &= \dfrac{-13+7}{8+4} (x - 8)\\\\y + 13 &= - \dfrac{1}{2} (x - 8)\\\\2y + 26 &= -x + 8\\\\x + 2y + 18 &= 0 \end{aligned}[/tex]

Answer:

Ratio of cost of a pen to cost of a ball pen is 15:7

Step-by-step explanation:

Given that:

Cost of dozen pens = ₹180

Unit rate = [tex]\frac{180}{12}[/tex]

Unit rate = ₹ 15 per pen

Cost of 8 ball pens = ₹ 56

Unit rate = [tex]\frac{56}{8}[/tex]

Unit rate = ₹7 per ball pen

Ratio of cost of a pen to cost of a ball pen,

15 : 7

Hence,

Answer:

The slope of this line is 1

Answer:

angle 1 = 51

angle 2 = 34

angle 3 = 95

angle 4 = 38

angle 5 = 47

angle 6 = 74

angle 7 = 59

Step-by-step explanation:

a straight line is 180 degree, so to find angle 1, subtract 129 by 180.

angle 2 is found by adding angle 1 and 95 then subtract that by 180.

angle 3 and 95 are opposite angles, so they are the same

for angle 4, add angle three and 47 then subtract that by 180

angle 5 is 47, they are opposite

angle 7, subtract 121 by 180

angle 6, you add angle 5 and 7, and subtract that by 180

Answer:

All you need to do is make sure the first expression is solved for y (which it is), and then substitute it into the second expression in place of any occurrences of y:

given the second expression:

x - y = 1

We'll replace y with it's value in the first expression:

x - (y) = 1

x - (5 - 2x) = 1

Now we can expand the resulting equation:

x - 5 + 2x = 1

So neither of the answers provided are correct.

You can then solve for x:

x - 5 + 2x = 1

x - 5 + 5 + 2x = 1 + 5

x + 2x = 6

3x = 6

3x/3 = 6/3

x = 2

After that, you can find y by plugging x into either of the two original equations:

y = 5 - 2x

y = 5 - 2(2)

y = 5 - 4

y = 1
