Answer:
b
Step-by-step explanation:
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

<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>
The rest are all incorrect
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
The correct answer is
as shown by the green line on the graph attached to this answer.
