Answer:

Valid is (32,12) , (6,36) , (20,20)

Invalid is (-4,40) , (36,-8), (15,22.5)

Step-by-step explanation:

I just got it right on edmentrum

Answer:

Valid solutions

(20,20)

(32,12)

(6,36)

Invalid solutions

(-4,40)

(36,-8)

(15,22.5)

Step-by-step explanation:

First, plot each point on the graph to determine whether it lies in the solution set.

All the points lie within the shaded region, so they are all solutions to the inequality.

Now, consider restrictions to the domain and range. Since x is the number of wallets and y is the number of hats, each x- and y-value must be a positive whole number. That leaves only the following points as valid solutions.

(20,20)

(32,12)

(6,36)

Answer:

0,0

Step-by-step explanation:

if you substitute the X and Y from the answer choices into each equation and check if they're true only 0,0 is true for both.

(0, 0) ordered pair is a solution of the system of inequalities

a relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is 2x−y≥−28x−y<5.

We need to find ordered pair is a solution of the system of inequalities.

Let us substitute the values of ordered pairs to check which is the solution.

(0, 0)

2(0)-(0)≥−28(0)−0<5.

2≥−28<5

-28<2 and -28<5

It satisfies both the conditions.

(0, 0) is the solution of the given inequality.

Hence, (0, 0) is the ordered pair is a solution of the system of inequalities.

Answer:

the  height of the pole is 220 centimeters

Step-by-step explanation:

The computation of the height of the pole is shown below

Here we applied the pythagoras theorem

Given that

Hypotenuse = 221 = c

And, base = 21 cm = b

a^2 + b^2 = c^2

So, the height is

= 21^2 cm - 221 cm

= 441 cm - 221 cm

= 220 cm

Hence, the  height of the pole is 220 centimeters

Answer:

FG= 30

Step-by-step explanation:

Point G is on line Segment FH

Given

FH= 4x

GH= x

FG= 2x+10

If the point G is on the line FH then the total of the two line segement FG and GH must be equal to FH

FH= FG+ GH

Putting the values in the above equation:

4x= 2x+10+x

4x= 3x+10  Solving for x

10= 4x-3x

10= x

FG= 2x +10

FG = 2(10) +10   Putting the value of x

FG= 20+10

FG= 30

Check :

FH= 4x= 4(10)= 40

GH= x= 10

FG = FH- GH= 40-10= 30

Answer:

f(x) = x²    increases at a faster rate than g(x) = 2x.

f(x)

Reason:

x =  0,   1,   2,   3,   4,   5,   6,   7

f(x) = 0,   1,  4,  9,   16,  25,   36,   49

g(x) = 0,  2,  4,   6,    8,  10,    12,    14.

Comparing the values of f(x) and g(x), we can see that that of f(x) are far higher than that of g(x) for the same values of x.

So f(x) increases at a faster rate.

- 10.35°C

Step-by-step explanation:

Given that :

Temperature at 6 AM for four consecutive days :

X : -12.1°C, -7.8°C, -14.3°C, and -7.2°C

The average temperature :

ΣX / n

n = sample size = number of days = 4

[(-12.1) + (-7.8) + (-14.3) + (-7.2)] / 4

= - 41.4 / 4

= - 10.35°C

Hence, the average 6 AM temperature for the four days is - 10.35°C

Answer:

(- 1, 7 )

Step-by-step explanation:

Given the 2 equations

3x - 4y = - 31 → (1)

- 3x - 3y = - 18 → (2)

Adding the 2 equations term by term will eliminate x, that is

0 - 7y = - 49

- 7y = - 49 ( divide both sides by - 7 )

y = 7

Substitute y = 7 into either of the 2 equations and solve for x

Substituting into (1)

3x - 4(7) = - 31

3x - 28 = - 31 ( add 28 to both sides )

3x = - 3 ( divide both sides by 3 )

x = - 1

solution is (- 1, 7 )

Given that the area of PQRS is 45 cm²

Area of PXYS = 10cm²

Now , from the figure we can see that ,

[tex]\bf\implies SY + YR = SR \\\\\bf\implies PX+XQ = PQ [/tex]

Also , we see that ,

[tex]\bf\implies ar(PSYX)= PS\times SY \\\\\bf\implies ar(XYRQ) = XY\times RQ [/tex]

And , we know that area of rectangle as ,

Finding a :-

[tex]\implies\bf ar(XYRQ) = XY\times RQ \\\\\bf\implies ( 45cm^2-10cm^2) = 7cm\times a \\\\\bf\implies 7a = 35cm^2 \\\\\bf\implies a =\dfrac{35cm^2}{7cm}\\\\\bf\implies\boxed{\red{\bf a = 5cm}}[/tex]
