The graph of the inequality y > x + 4 matches the description in Option(c)

a shaded region above a dashed boundary line.

Given function: y > x + 4

Let's plot the graph of the given function and then match it with the options to see which is the solution.

So we will Plot y = x + 4 (as a dashed line because y > )

the coordinates will be,

x = 0 , y = 4

x = -1 , y = 3

x = -2 , y = 2

x =  1 , y = 5

x = 2 , y = 6

The purple shaded region satisfies the inequality y > x + 4.

Hence the graph description is a shaded region above a dashed boundary line.

Answer:

$227 = washing machine cost

$391 = dryer cost

Step-by-step explanation:

$618 divided by 2 = 309

309 - 82 = 227 = cost of washing machine

618 - 227 = 391 = cost of dryer

You can double-check by,

391 + 227

= 618

$227 = washing machine cost

$391 = dryer cost

If the American Heart Association suggests a target heart rate of T=0.75(220-a),  Proving  that given a person's target heart rate, you can calculate his or her age using the formula a=220- /0.75. His/her age is 16 years.

a. Given:

T=0.75(220-a)

where

T =a person's target heart rate

a= his or her age

Prove:

Hence:

T=0.75(220-a)

T/0.75=220-a

T/0.75-220=a

-T/0.75+220=a

a=-T/0.75+220

a=220-T/0.75

b. How old is she:

a=220-T/0.75

where:

T=153

Substitution

a=220-153/0.75

a=220-204

a=16 years

Therefore proving  that given a person's target heart rate, you can calculate his or her age using the formula a=220- /0.75. His/her age is 16 years.

a. Prove that given a person's target heart rate, you can calculate his or her age using the formula a=220- T/0.75.

b. If Mai-Lin’s target heart rate is 153, then how old is she? What property justifies your calculation?

Answer:

All of the options.

Step-by-step explanation:

We first subtract 8 from both sides. We now divide both sides by -1. However, something to keep in mind, is when you multiply/divide by a negative number, you just flip the sign. In this case, we need to divide both sides of the equation by -1, to get b and our answer. So now, we need to find an answer from our answer choices that is smaller than -19. I think all of them would be right in this case, as they fit the equation. So all of them should be right (: As if you plug in the values, you get answers that could be solutions to the equation!

The equation of the parabola that models the given situation is y = [tex]\frac{-1}{6}(x-3)^{2}[/tex] + 1.5.

A parabola is a roughly U-shaped mirror-symmetrical plane curve. It corresponds to a number of seemingly unrelated mathematical descriptions that all define the same curves.

To represent a parabola algebraically in the coordinate plane, the standard equation of a parabola is used. The general equation of the parabola is given by  y = [tex]a(x-h)^{2}[/tex]+ k or x = [tex]a(y-k)^2[/tex] +h, where (h,k) denotes the vertex. A regular parabola's standard equation is [tex]y^2[/tex] = 4ax.

Now, the equation of parabola for the given situation is calculated as:

y = [tex]a(x-3)^2[/tex]+ 1.5

Now, put the value of x = 0 and y = 0.

0 = [tex]a(0-3)^2[/tex]+ 1.5

0 = 9a + 1.5

-9a = 1.5

a = - 1.5/9

a = -1/6

Now, put the value of a in equation y = [tex]a(x-3)^2[/tex]+ 1.5 to obtain:

y = [tex]\frac{-1}{6}(x-3)^{2}[/tex] + 1.5.

Cheyenne can buy a maximum of 13 bags of Takis.

We have,

To find the maximum number of bags of Takis Cheyenne can buy with $20, we need to divide the total amount of money she has by the cost per bag of Takis.

Cost per bag of Takis = $1.50

Total money Cheyenne has = $20

Maximum number of bags of Takis = Total money / Cost per bag

Maximum number of bags of Takis = $20 / $1.50

Maximum number of bags of Takis = 13.33

Since Cheyenne cannot buy a fraction of a bag, the maximum number of bags of Takis she can buy is 13.

Thus,

Cheyenne can buy a maximum of 13 bags of Takis.

The rule for the function g(x) is:

g(x) = 1.15*(x^2 - 3x -16)

First we know that the function f(x) is f(x) = x^2 - 7x

And we know that h(x) is a translation of 6 units down and 2 units to the left of f(x), then:

h(x) = f(x + 2) - 6

Now we know that g(x) is 115% of h(x), then we can write:

g(x) = 1.15*h(x)

Replacing h(x) by the rule above we get:

g(x) = 1.15*(f(x + 2) - 6)

Replacing the actual function there:

g(x) = 1.15*( (x + 2)^2 - 7*(x + 2) - 6)

g(x) = 1.15*( x^2 + 4x + 4 - 7x - 14 - 6)

g(x) = 1.15*(x^2 - 3x -16)

Total number of students in a class is 50.

A class has 40% of women.

Total Number of women in a class = 20                              equation 1

Let total number of students in a class = x

According to the question a class has 40% of women. Mathematically we can write it as,

Total Number of women in a class = 40 % of x

Total Number of women in a class = ( (40x) / 100 )               equation 2

On equating equation 1 and equation 2, we get

20 = ( (40x) / 100 )

⇒ 40x = 2000

⇒ x = 50

The percentage of its original price is -17.65%

The given parameters are

Selling price = $59.50

Original price = $70

The percentage of the original price is calculated as

Percentage = (Selling price - Original price)/Original price * 100%

Substitute the known values in the above equation

So, we have

Percentage = (59.50 - 70)/59.50 * 100%

Evaluate the difference in the above equation

So, we have

Percentage = -10.5/59.50 * 100%

Evaluate the quotient in the above equation

So, we have

Percentage = -0.1765 * 100%

Evaluate the product in the above equation

So, we have

Percentage = -17.65%

Hence, the percentage of its original price is -17.65%

The quotient of an expression of signs decimal numbers is positive:

= 0.16.

The correct option is B.

There is one key notion when dividing any negative integer by another: the negative signs cancel out. This is unique to this situation. A positive number divided by such a negative number equals a negative number. As a result, you can't divide any two numbers as well as expect a positive result. In general, negative and positive numbers behave differently.

For

a. 2.5 / -9.56

dividing the numbers we get:

= -0.26

For

b. -1.7 / -10.06

dividing the numbers we get:

The probability that the game will be won before the fourth turn is [tex]\frac{91}{216}[/tex].

Probability refers to the possibility of the occurrence of an event.

P(E) = probability of occurrence of an event E = [tex]\frac{Number Of Favourable Outcomes}{Total Number Of Outcomes}[/tex]

Now,

Probability of winning the game in first turn = [tex]\frac{1}{3}\frac{1}{2}=\frac{1}{6}[/tex]

Probability of losing the first game but winning the second one = [tex]\frac{5}{6}\frac{1}{6} = \frac{5}{36}[/tex]

Probability of losing the first two games but winning the third one = [tex]\frac{5}{6}(\frac{5}{6})\frac{1}{6} = \frac{25}{216}[/tex]

Thus, the probability of winning the game before fourth turn = [tex]\frac{1}{6}+\frac{5}{36}+\frac{25}{216}=\frac{91}{216}[/tex]

The value of angle m< EBF  is determined as 56⁰.

The sum of angles in a straight line is 180 degrees. The value of angle EBF can be determine using the concept of sum of angles in a straight line as shown below.

m< EBC  + m< ABE = 180

3y + 10 + 2y - 20 = 180

5y - 10 = 180

5y = 180 + 10

5y = 190

y = 190/5

y = 38

The value of m< EBF is calculated as follows;

Assuming equal division, m< EBF = m< ABE

m< EBF = 2y - 20

m< EBF = 2(38) - 20

m< EBF = 56⁰

Thus, the value of angle m< EBF  is determined as 56⁰.
