Which ordered pair is a solution of the system of inequalities below?
{2x−y≥−28x−y<5
(0, 0)
(1, 0)
(0, – 5)
(– 2, 0)
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
What is Inequality?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.

Point G is in love segment FH give an FH equals 4XGH equals XNFG Eagles 2X +10 determine the numerical link of FG
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

How do you solve,
3x - 4y = -31
-3x - 3y = -18
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 )

Determine which points are valid solutions and which are invalid, and then drag them to the correct location on the table.
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)

This helicopter has a rotor that moves at a rate of 600 spins per minute while flying. Which statement is supported by this information
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

[tex]\boxed{\boxed{\pink{\bf \leadsto Value \ of \ a \ is \ 5cm \ and \ b \ is \ 2cm .}}}[/tex]
Step-by-step explanation: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]
Hence the value of a is 5cm and b is 2cm .What is the complete factorization of x^2 + 2x − 63?

D. (x − 21)(x + 3)
Answer:
C. (x+9)(x-7)

Which function increases at a faster rate on 0 to infinity
fo= Zorg) = 22? Explain your reasoning
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.
