Write the system as an augmented matrix:

[tex]\left[\begin{array}{cc|c}1&5&22\\4&-7&7\end{array}\right][/tex]

Add -4 (row 1) to row 2 :

[tex]\left[\begin{array}{cc|c}1&5&22\\0&-27&-81\end{array}\right][/tex]

Multiply row 2 by -1/27 :

[tex]\left[\begin{array}{cc|c}1&5&22\\0&1&3\end{array}\right][/tex]

Add -5 (row 2) to row 1 :

[tex]\left[\begin{array}{cc|c}1&0&7\\0&1&3\end{array}\right][/tex]

Then x = 7 and y = 3.

Answer:

The fraction is a proper fraction (and irreducible)

Step-by-step explanation:

Given

[tex]x = Numerator[/tex]

[tex]y = Denominator[/tex]

[tex]Common\ factor = 1[/tex]

Required

The type of fraction

A fraction with the given features is a proper fraction and cannot be further reduced.

Take for instance:

[tex]x = 2[/tex]

[tex]y = 7[/tex]

The only common factor between [tex]2\ and\ 7[/tex] is 1

[tex]\frac{x}{y} = \frac{2}{7}[/tex]

See that 2/7 is a proper fraction and also 2/7 cannot be reduced (simplified)

The above logic is applicable to all fraction that have the attribute stated in the question (e.g. 3/7, 3/8, 4/9, 7/10, etc.)

d i hope am sorry if i calcuc wrong

Step-by-step explanation:

Answer:

The domain of the square root function f(x)=√x is given in interval form by: [0,+∞)

The range of the square root function f(x)=√x is given in interval form by: [0,+∞)

The x and y intercepts are both at (0,0)

The square root function is an increasing function.

Answer: Devin's

Step-by-step explanation:

Given

Devin's nature reserve is 14 hectares

Sam's nature reserve is [tex]14\times 10^6\ m^2[/tex]

Also, [tex]1\ \text{hectare}=10,000\ m^2[/tex]

Devin reserve in square meter [tex]14\ \text{hectares}=14\times 10^4\ m^2[/tex]

Clearly, [tex]14\times 10^6> 14\times 10^4[/tex]

So, Devin's manages smaller area

Step-by-step explanation:

B. In the morning, Shawn added six hard candies to a jar which contained four hard candies.

So he had 10 candies.

By the end of the day he ate ten candies from this jar.

Now he had 10-10 = 0, zero candies.

Answer:

B

Answer:

9 and 10

Step-by-step explanation:

square root of 96 is 9.79795897113

Answer:

9 and 10

Step-by-step explanation:

because square of 9 is 81

and square of 10 is 100

81<96<100

so it lies between 9 and 10

Answer:

58

nth term is 25 i think

Step-by-step explanation:

The next number is

58.

Each number is +11

So, the next number that comes after 47 is 58.

14+11= 25

25+11= 36

36+11=47

47+11=58

Answer:

A-3/4=1/8 is the equation, if you expand 3/4 it is 6/8, in order to get 1/8 you need to subtract 6/8 from 7/8

7/8-6/8=1/8 therefor A=7/8

Answer:

176.25in^2

Step-by-step explanation:

You can tell that the two triangles on the left, and the two triangles on the right make a rectangle if you flip one of them. Because of this, you can multiply the base and height to get the area of both.

7.5*16=120 (left side)

7.5*7.5=56.25 (right side)

Now we add them to get the full area:

120+56.25=176.25in^2

Answer:

1 - 1/24 = 23/24

Step-by-step explanation:

Answer:

Solution given:

A(a,b) lie in 6x-y =1

substituting value of A in equation ,we get

6a-b=1...................(1)

B(b,a) lie in 2x - 5y = 5

substituting value of B in equation ,we get

2b-5a=5

b=5(a+1)/2............(2)

substituting value of b in equation 1 ,we get

6a-5(a+1)/2=1

12a-5a-5=2

7a=2+5

a=[tex] \frac{7}{7} [/tex]=1

substituting value of a in equation 1 ,we get

6×1-b=1

6-1=b

b=5

so points are A(1,5) and B(5,1)

we have

equation of line having two points

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1) [/tex]

[tex](y - 5) = \frac{1-5}{5-1} (x - 1) [/tex]

[tex](y - 5) = -1 (x - 1) [/tex]

y-5=1-x

x+y=6 is a required equation of line AB.

Answer:

clockwise

Step-by-step explanation:

Answer:

Clockwise

Step-by-step explanation:

Answer:

False.

Step-by-step explanation:

We have the ordered pair (10, 6) and we want to see if this ordered pair is a solution of the inequality:

y  ≤ -5/5x+3

Remember that a generic ordered pair is written as (x, y)

Then for the ordered pair (10, 6) we have:

x = 10

y = 6

So we just need to replace these two values in the inequality and see if the inequality is true or false.

Replacing these values we get:

6  ≤ (-5/5*10) + 3

6  ≤ (-1/10) + 3

This is false, 6 is not less than the thing at the right, so we can conclude that (10, 6) is not a solution of the inequality.

So the coordinate pair makes the inequality false.

Answer:

bolded

Step-by-step explanation:

2. 11= 3z +5

 6 = 3z    z= 2

3. 2s - 4 = 6

   2s=10      s= 5

4. 5r + 8 = -12

   5r = -20     r= -4

5. -6p - 3 = 9

    -6p = 12    p= -2

6. 3x + x -2 = -14

  4x = -12    x= -3

7. 5c + 2 -3c = 10

   2c = 8    c=4

8. 3 + 7n +2n = 21

  9n = 18   n=2

9. 6r + 5 - 7r =21

      -1r =16     r= -16

10. 8 - 5b= -7

      -5b = -15    b= 3

11. 6 - 4m= -10

    -4m = -4    m= 1

12. -3t + 4 =19

      -3t = 15     t= -5

13. a= 18
