Q9.
svet-max [94.6K]

After solving simultaneously we found the values for x and y are

2.76 and 5.65 respectively

<h3>Simultaneous Equations</h3>

We have the following two expressions

7x – 2y = 34 --------1

3x + 5y = -3 ---------2

Multiply 1 by eqn 5 and eqn 2 by 2

35x - 10y = 170-------3

6x + 10y = -6 ----------4

subtracting 4 from 3 we have

29 x= 164

divide both sides by 29

x = 164/29

x = 5.65

Put x = 5.65 in eqn 1 to find y

7*5.65 – 2y = 34

39.55 - 2y = 34

39.55-34 = 2y

5.55 = 2y

divide both sides by 2

x = 5.55/2

x = 2.76

A student worked out at a gym continuously for 50 minutes. The graph shows the remaining percentage of the workout as a linear f
Cloud [144]

Answer:

  • C. Domain:  All real numbers greater than or equal to 0 and less than or equal to 50. Range: All real numbers greater than or equal to 0 and less than or equal to 100

Step-by-step explanation:

  • <em>Refer to attached</em>

<u>Continuation of the question:</u>

Which answer choice best describes the domain and range of the function for this situation?

A

  • Domain: All real numbers greater than or equal to 0 and less than or equal to 100
  • Range: All real numbers greater than or equal to 0 and less than or equal to 50

B

  • Domain: (-2)
  • Range: (100)

C

  • Domain: All real numbers greater than or equal to 0 and less than or equal to 50
  • Range: All real numbers greater than or equal to 0 and less than or equal to 100

D

  • Domain: (100)
  • Range: (-2)

------------

As per the graph, the domain is x-values in the interval [0, 50] minutes and the range is y-values in the interval [0, 100] percentage.

<u>Correct answer choice is therefore:</u>

  • Option C

The rest are all incorrect

PLEASE HELP! Find code (answer)
alexandr1967 [171]

Answer:

code = 56

Step-by-step explanation:

E = GCF(22,30) = 2

F = LCM(3,8) = 24

Given

3 * (7+10) = G +30 => 51 = G + 30 => G = 21

5 * (3+H) = 15 + 45 => 3+H = (60/5)  = 12 => H = 12 - 3 = 9

Sum E + F + G + H = 2 + 24 + 21 + 9 = 56
