Each plan utilizes a combination of 3 strength-training sessions and 3 aerobic exercise sessions per week.
Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week.
Let y be the number of strength-training exercises per week.
Let x be the number of aerobic exercises per week.
For the beginner plan, the equation would be gotten as;
15y + 20x = 90 ------(eq 1)
The equation to represent the advanced plan would be;
20y + 30x = 130 -------(eq 2)
Multiply both sides of eq 1 by 4 to get:
60y + 80x = 360 ------(eq 3)
Multiply both sides of eq 2 by 3 to get:
60y + 90x = 390 ------(eq 4)
Subtract eq(3) from eq(4) we get:
10x = 30
Thus; x = 3
Then; 15y + 20(3) = 90
15y = 30
y = 2
Thus, the correct statement is:
"Each plan utilizes a combination of 2 strength-training sessions and 3 aerobic exercise sessions per week."

The range is {y|y ≤ 6}.
The function is increasing over the interval (–∞ , –2).
The function is decreasing over the interval (−4, ∞).
The function has a positive y-intercept.
we have
using a graph tool
see the attached figure
Statements
case 1) The domain is {x|x ≤ –2}
Is false. the domain is all real numbers---------> interval (-∞,∞)
case 2) The range is {y|y ≤ 6}.
Is true
Is a parabola open down, the vertex is the point
the range is the interval ------> (-∞,-6]
case 3) The function is increasing over the interval (–∞ , –2).
Is true (see the graph)
case 4) The function is decreasing over the interval (−4, ∞)
Is false
In the interval (-4,-2) the function is increasing and in the interval (-2, ∞) the function is decreasing
case 5) The function has a positive y-intercept
Is true
The y-intercept is the point
therefore
the answer is
The range is {y|y ≤ 6}
The function is increasing over the interval (–∞ , –2)
The function has a positive y-intercept
Number 12 have factors 12 = ( 1,2,3,4,6,12)
Number 18 have factors 18= ( 1,2,3,6,9,18 )
According to this we can conlude that numbers 12 and 18 have in common (1,2,3 and 6).
Good luck!!!
2 and 6 can go into it evenly
