X+ y = 2....multiply by -2
2x + 5y = 16
--------------
-2x - 2y = -4 (result of multiplying by 2-)
2x + 5y = 16
-------------add
3y = 12
y = 12/3
y = 4
x + y = 2
x + 4 = 2
x = 2 - 4
x = -2
solution is (-2,4)
I don't understand the question doesn't make any sense to me sorry for wating ur time but I need the points
Answer:
See explanation
Step-by-step explanation:
If segment AB is tangent to the smaller circle, than AB⊥OR. Consider two right triangles AOR and BOR. In these triangles:
- OR is common leg;
- AO=OB as radii of larger circle;
- ∠ARO=∠BRO, because AB⊥OR.
By HL theorem, ttriangles AOR and BOR are congruent. This gives you that AR=RB.
Considering the given graph, it is found that the numeric value of the function r(x) at x = -3 is of 2.
<h3>How to find the numeric value of a function given it's graph?</h3>
The numeric value of a function is the value of y for the given value of x, hence, we have to look at the value of x on the horizontal axis, and verify the equivalent value of y on the vertical axis.
In this problem, when the horizontal axis is of x = -3, the vertical axis is of y = 2, hence the numeric value of the function r(x) at x = -3 is of 2.

Actually Welcome to the Concept of the Differential Calculus.
Since, we know this is a definite calculus,
thus we get here as, by using the Chain Rule.
