Answer:

Step-by-step explanation:
Given:
An isosceles triangle ABC with AB = AC.
∠A = 
∠B = 
∠C = 
We know that, for an isosceles triangle, the angles opposite equal sides are also equal to each other.
Therefore, ∠B = ∠C
⇒ 
⇒ 
∴ ∠C =
°
Now, the sum of all the interior angles of a triangle is always 180°.

Therefore, the value of 'y' is 5.
8/9 divided by 2/3 is 1 1/3
Y = 2x + 7
Function notation
f(x) = 2x + 7
The function that models the profit of the company in million of dollars is:

where x represents the number of years since the company started. We want to find when the profit of the company was $4 million. Setting P as 4 in above equation, we can find the value of x when the profit was $4 million.
Thus, we can conclude that the profit of the company was $4 million in 2nd and 4th year
Answer:
D
Step-by-step explanation:
The solution to a system of equations given graphically is at the points of intersection of the 2 graphs.
These occur at (4, 8 ) and (0, - 8 ) → D
