Identify the system of equations that is not satisfied by the given ordered pair.
(5, 3) or m = 5, n = 3
2m = 19 − 3n
m − n = 2
6m − 21n = −33
8m = −23 + 21n
4m − 3n = 11
2m + 5 = 5n
9m + 4n = 5
3m = 9 + 6n

Answers

Step-by-step explanation:

2+5=7 = 19-3+3=13

5-3=2

6+5=11-21+3= -33

8+5= 13= 1

4+5= 9

The system of equations that does not satisfy the ordered pair is

6m -21n = -33  

9m + 4n = 5

3m = 9 + 6n

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the ordered pair ( m , n ) = ( 5 , 3 )

The value of m = 5

The value of n = 3

Now , the equation will be

a)

The equation is

2m = 19 - 3n

Substituting the values , we get

2 x 5 = 19 - 3 x 3

10 = 19 - 9

10 = 10

The equation satisfies for the ordered pair

b)

The equation is

m - n = 2

Substituting the values , we get

5 - 3 = 2

2 = 2

The equation satisfies for the ordered pair

c)

The equation is

6m -21n = -33

Substituting the values , we get

6 x 5 - 12 x 3 = -33

30 - 36 = -33

-3 = -33

The equation does not satisfy the ordered pair

d)

The equation is

8m = −23 + 21n

Substituting the values , we get

8 x 5 = -23 + 21 x 3

40 = -23 + 63

40 = 40

The equation satisfies for the ordered pair

e)

The equation is

4m − 3n = 11

Substituting the values , we get

4 x 5 - 3 x 3 = 11

20 - 9 = 11

11 = 11

The equation satisfies for the ordered pair

f)

The equation is

2m + 5 = 5n

Substituting the values , we get

2 x 5 + 5 = 5 x 3

10 + 5 = 15

15 = 15

The equation satisfies for the ordered pair

g)

The equation is

9m + 4n = 5

Substituting the values , we get

9 x 5 + 4 x 3 = 5

45 + 12 = 5

57 = 5

The equation does not satisfy the ordered pair

h)

The equation is

3m = 9 + 6n

Substituting the values , we get

3 x 5 = 9 + 6 x 3

15 = 9 + 18

15 = 27

The equation does not satisfy the ordered pair

Hence , the equations 6m -21n = -33  ,  9m + 4n = 5 and 3m = 9 + 6n   does not satisfy the given ordered pair ( m , n ) = ( 5 , 3 )

M varies directly as the square of N. if N increases by 10%,find the percentage change in M​

Answers

Answer:

21%

Step-by-step explanation:

I think this id right but not 100% sure. I made N a random number (5 in my case) then squared it to make it 25. That means M is 25. So if we increase N by 10 percent (.5) it is 5.5 x 5.5 = 30.25. Then i found the difference between the two (5.25) and found the percentage difference (21%). Basically divided 5.25 by 25 and that is the answer. Hope this is right!!!!

Answer: The function that represents the inequality of the given graph is;

Option A

Graph Inequalities

From the given graph, the curve with the shaded dot shows less than or equal to because the dot indicates that the maximum input value of x is at that point.

Secondly, the curve without a shaded dot shows that the input function of x is only greater than 3.

Looking at the options, option A is right and we will prove it thus;

for y = x³ - 3

At x = 2, we see that;

y = 2³ - 3

y = 5

This corresponds with the given equation

For the second curve, for y = x² + 6;

At x = 2, we have;

y = 2² + 6

y = 4 + 6

y = 10

This corresponds with what is given and is thus correct.

This, option A is the correct answer

Choose the equation of the line in slope-intercept form.
Parallel to the x-axis and has the point (-1,9).

A. x = -1
B. y = 9
C. y = -1
D. x = 9

Answers

Answer:

B)   y = 9

Step-by-step explanation:

Equation of a line in slope-intercept form:  y = mx + b

(where m is the slope (gradient) and b is the y-intercept)

If the line is parallel to the x-axis, the slope is zero.

Therefore, y = (0)x + b

⇒ y = b

We are told that the line passes through point (-1, 9).  Therefore, the y-intercept is 9.

So the equation of the line is:  y = 9

The final velocity of an object moving in one dimension is given by the formula v = u + at, where u is

subtract u from both sides

v - u = at

Step-by-step explanation:

Solve:

Plug in in 6x for y in 4x + y = 7

4x + y = 74x + 6x = 710x = 7x = 0.7

Plug in 0.7 for x in y = 6x

y = 6xy = 6(0.7)y = 4.2

x = 0.7
y = 4.2

Coordinate form : (0.7, 4.2)

-Chetan K

Answer:

x = 7/10 (fraction)

Step-by-step explanation:

Given that y = 6x, we can substitute it for y

That makes your equation:

4x + 6x = 7

Now, all we need to do is solve for x:

Step 1: Add similar elements:

4x+6x=10x, which gives you 10x=7

Divide next:

10x/10=7/10 (10/10 = 0 and 7/10 = 7/10)

x= 7/10

You know x is a number less than 4. Select all the inequalities that must be true.
x-2 > 2
x+6 < 10
x < 2
5x < 20
x < 8

Answers

Answer:

x+6 < 19

5x < 20

x < 8

Step-by-step explanation:

To solve this problem, you have to plug in numbers for every statement to see if it is true or not. You know that x is a number less than 4, so we can use 3 as an example.

x-2 > 2 | ❌

This can be rewritten as 3-2 > 2 (since we are plugging in 3, any number less than 4 works)

That is equal to 1 > 2, which is not correct. One is not larger than two.

x+6 < 19 | ✅

This can be rewritten as 3+6 < 19 (for the same reason as above)

That is equal to 9 < 19. 19 is greater than 9, so this is correct.

x < 2 | ❌

This can be rewritten as 3-2 > 2.

That is equal to 1 > 2, which is wrong.

5x < 20 |

This can be rewritten as 5 x 3 < 20

That is equal to 15 < 20, which is correct. 15 is less than 20.

x < 8 |

This can be rewritten as 3 < 8.

3 is less than 8, so this is correct.
