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: d. The helicopter rotor will spin 36,000 times in 1 hour

Step-by-step explanation:

Option A is wrong because in 40 minutes the rotor will spin:

= 40 * 600

= 24,000 times

Option B is wrong because we cannot know the number of times the rotor will spin before being lifted off of the ground with the details given.

Option C is wrong because in 3 hours the rotor will spin:

= 600 * 3 * 60 minutes

= 108,000 times

Option D is correct because in 1 hour the rotor will spin:

= 600 * 1 * 60 mins

= 36,000 times

Answer:

the answer will be D because it looks like it would be d

Step-by-step explanation:

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 )

Answer:

-1and 7 hope it helpssss

Answer:

You are correct, the answer that you highlighted

Step-by-step explanation:

We know y is LESS than the expression, therefore the shaded area would be at the bottom. Furthermore, the expression tells us simply that y is LESS than 1-3x, NOT EQUAL. Therefore, the graph must have a dotted line.

Answer:

C. 21.25 ( i'm assuming that C. says 21.25)

Step-by-step explanation:

Since it's an isosceles triangle, the two bottom angles are equal to one another. So 180 - 75 = 105. 105 ÷ 2 = 52.5

2x + 10 = 52.5

2x = 42.5

x = 21.25

Answer:

x=21.25

Step-by-step explanation:

triangle = 180 degree angle

knowns:

75 degrees and two opposing sides with same length have same angles

so:

180-75= 105

2(2x+10)=105

4x+20=105

4x=105-20

4x=85

x=85/4

x=21.25

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2 * ( L + W)

The length of a rectangle is 5 inches less than 4 times the width.

Assume the width is x. Length is:

4x - 5

Equation is therefore:

2 * (4x - 5 + x) = 110

4x - 5 + x = 110/2

5x - 5 = 55

5x = 55 + 5

x = 60/5

x = 12 inches

If width is 12 inches, then length is:

= 4x - 5

= 4 * 12 -5

= 43 inches

[tex]\boxed{\boxed{\pink{\bf \leadsto Value \ of \ a \ is \ 5cm \ and \ b \ is \ 2cm .}}}[/tex]

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 ,

[tex]\large\boxed{\red{\bf Area_{rectangle}=lenght\times breadth }}[/tex]

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]

Finding b :-

[tex]\implies\bf ar(PSYX)= PS\times SY \\\\\bf\implies 10cm^2 = b \times 5cm \\\\\bf\implies b =\dfrac{10cm^2}{5cm} \\\\\bf\implies\boxed{\red{\bf b = 2cm}}[/tex]

[tex]2\cdot(x-4)^2 -6 = 0 \\~\\ 2\cdot(x-4)^2 = 6 \\~\\(x-4)^2 = 3 \\~\\x-4 = \pm\sqrt{3} \\~\\x =4\pm\sqrt{3}[/tex]
