Use DESMOS and then take the points that are given and then plug them into your equations to show your work.
Desmos helps all equation problems that you need solved because it not only solves it, but also has it graphed with marked points.
It helped me through highschool.
The value of (k ○ r) (x) from the given parameters in the task content is; 5 ln(2x³ -14)
<h3>What is (k ○ r) (x) from the task content?</h3>
If follows from the task content that;
- r(x) = x³ - 7 and k(x) = 5 ln (2x)
It therefore follows that;
(k ○ r) (x) = k(r(x)) = 5 ln (2(x³-7)).
On this note, the expression which represents (k ○ r) (x) is; 5 ln(2x³ -14).

Answer:
x = -2, y=1
Step-by-step explanation:
x-7y=-9---------------------equation 1
-x+8y=10-------------------equation 2
From equation 1, make x the subject of formula
x=7y-9----------------------equation 3
substituting x=7y-9 in equation 2,
-(7y-9)+8y=10
Expanding bracket
-7y+9+8y=10
Collecting like terms
8y-7y=10-9
y=1
substituting y=1 in 3
x=7(1)-9
x=7-9
x=-2
