Answer:
x = 
or 0.706
or 1.735
Step-by-step explanation:
5x + 2y=7 ----->(eq 1)
- 2x + 6y=9 ----->(eq 2)
Multiply (eq 1) with 3
3×(5x + 2y) = 3×7
15x + 6y = 21 ----->(eq 3)
substract (eq 3) from (eq 2)
- 2x + 6y - (15x + 6y) = 9-21
- 2x + 6y - 15x - 6y = 9-21
- 2x - 15x + 6y - 6y = 9-21
-17x = -12
x = -12 ÷ -17
x =
put x = in (eq 1)

Answer:
135
Step-by-step explanation:
Ratio = 3 : 9
Angles are : 3x , 9x
3x + 9x = 180 {supplementary angles}
12x = 180 {divide both side by 12}
x = 180/12
x = 15
Larger angle = 9x = 9*15 = 135
The reasonable value for the range of the given function is: A. 75.
<h3>What of the Range of a Function?</h3>
The range of a function is the output that a corresponding input value would give as a relation.
In this scenario, the grade you get is a function of number of hours you study. Range is the grade (output), while the domain is hours of study (input).
The given possible range values in the options are, 75, 1.25, -30, 1/2.
A reasonable value of a a grade cannot be a negative number, neither can it be 1.25, nor 1/2.
Therefore, the reasonable value of the range is: A. 75.
