A constraint is a restriction or limitation on the possible solutions of a problem or system. In the context of a system of inequalities, a constraint is an inequality that must be satisfied by any solution of the system. A system of inequalities is a set of multiple inequalities that must all be satisfied simultaneously. Solving a system of inequalities involves finding the set of all possible solutions that satisfy all of the constraints. This can be done graphically by graphing the inequalities and finding the intersection of their solution sets, or algebraically by isolating the variables and solving for their values.

If m∠DAC = 65°, m∠DAC and m∠BCA can be classified as alternate interior angles. And m∠BCA = 65°.

Alternate interior angles of a rectangle are congruent, which implies they are equal in measure and are formed by the intersection of the opposite sides of the rectangle.

Considering the diagonal AC from one corner of the rectangle to the opposite corner, the angles formed at the intersection of the non-parallel sides will be congruent

Therefore, the angles m∠DAC and m∠BCA are alternate interior and m∠DAC = m∠BCA, which makes m∠BCA = 65°

Answer:12 feet

Step-by-step explanation:

The length of segment PR is given by the following option:

The angle measure of the altitude is given as follows:

m < RSP = 5x + 40º.

The altitude of the triangle is always going to form a right angle, with measure of 90º, hence the value of x is obtained as follows:

5x + 40 = 90

5x = 50

x = 50/5

x = 10.

The length of segment PR is given as follows:

PR = x - 1.

As the value of x is of x = 10, the numeric length of the segment is given as follows:

PR = 10 - 1

PR = 9.

Meaning that the correct option is given by option C.

Solution of the given inequalities based on integer 'n' is given by :

a. Value of 'n' for 15n > 12n + 18 is n > 6.

b. All the possible integer value of 'n' for -2 <n + 3 ≤ 4 are -4, -3, -2, -1, 0.

a. Solution of the expression 15n > 12n + 18 is :

15n > 12n + 18

Subtract 12n from both the sides ,

⇒ 15n - 12n >  12n - 12n + 18

⇒ 3n > 18

Divide by 3 from both the sides,

⇒ 3n/3 > 18 /3

⇒ n > 6

b.  -2 <n + 3 ≤ 4

where 'n' is an integer

⇒ -2 -3 < n + 3 -3 ≤ 4 -3

Answer: (30, 5)

Step-by-step explanation:

Since the 3 red angles are equal, then they are all 60 degrees, which shows that the triangle is equilateral.  Therefore, 8y = 40, so y = 5

Also, since BD = BC, triangle BDC is isosceles. We know that angle BDC = 180 - 60 = 120, so 2x = 60 and x = 30

(x, y) = (30, 5)

This triangle is an acute triangle because all three angles measure less than 90 degrees.

It is also a scalene triangle because all three sides have different lengths. I know this because an acute triangle is defined as a triangle where all three angles measure less than 90 degrees and a scalene triangle is defined as a triangle where all three sides have different lengths.

According to the lengths of sides, triangles can be classified into :
Scalene.
Isosceles.
Equilateral.

The average rate of change of the account value from t = 0 to t = 5 is the change in the account value divided by the change in time, or (A(5) - A(0))/(5 - 0).

We can substitute the given function into the equation:

A(t) = 50,000(1.02)^t

So,

A(5) = 50,000(1.02)^5

and

A(0) = 50,000(1.02)^0

Now we can substitute these values in the equation of average rate of change:

(A(5) - A(0))/(5 - 0) = (50000(1.02)^5 - 50000(1.02)^0) / (5-0)

This simplifies to

(50000(1.02)^5 - 50000) / 5

Which is approximately equal to 67,622.05

So the average rate of change of the account value from t = 0 to t = 5 is approximately 67,622.05.

For the given situation sentence represents amount of the sparkling water bought by Layla is given by :

Option A). Layla bought 20milliliters less sparkling water than 2 liters.

Sparkling water in each pack is equal to 330 milliliters

Number of packs of sparkling water bought by Layla is equal to 6 packs

Amount of sparkling water in 6 packs = 330 milliliters

⇒ Amount of sparkling water in 6 packs = ( 330 × 6 ) milliliters

⇒ Amount of sparkling water in 6 packs = ( 1980 ) milliliters

1 liter = 1000milliliters

⇒ 2 liter = 2000milliliters

1980 is less than 2 liters

Difference between 1980milliliters and 2 liters

2000 - 1980 = 20milliliters

Answer: 31

Step-by-step explanation:

7 × 1 = 7

217/7 = 31

Check the picture below.

A)

House 1 value is an exponential function.

House 2 value is a linear function.

B)

House 1:

f(x) = 253,980 x

House 2:

f(x) = 256,000 + 7000x

C)

House 1 will have the greatest value.

The significant difference in the value of either house after 45 years is $168844

The value of house 1 after 45 years:

f(45) = $739844

The value of the house 2 after 45 years:

f(45) = $571000

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

House 1:

The value of the hours is described by an exponential function.

There is an increase of 2% per year.

f(x) = 253,980 x [tex]1.02^x[/tex]

Where x is the number of years.

House 2:

The value of the hours is described by a linear function.

There is an increase of $7000 per year.

f(x) = 256,000 + 7000x

Where x is the number of years.

Now,

For x = 45,

f(45) = 253,980 x [tex]1.02^x[/tex]

f(45) = 253,980 x [tex]1.02^{45}[/tex]

f(45) = $739843.74

f(45) = $739844 ____(1)

f(x) = 256,000 + 7000x

f(45) = 256,000 + 7000 x 45

f(45) = 256,000 + 315000

f(45) = $571000 ______(2)

From (1) and (2),

House 1 will have the greatest value.

The significant difference in the value of either house after 45 years

= $739844 - $571000

= $168844

The value of house 1 after 45 years:

f(45) = $739844
