Step-by-step explanation:
1) according to the condition two angles are equal, then two sides are equal also, it means
2) √x+4=√(5x+4);
3) the 'x' can be calculated if to solve this equation:
;



4) finally, answer: 9.
Answer:
See picture attached below.
Step-by-step explanation:
To graph the system, graph each line separately.
y = 3x + 3 ha slope 3 and y-intercept 3.
Start at 3 on the y-axis and mark a point. Then from this point move up 3 units and to the right 1 unit. Mark a point and connect.
y=-x - 3 has slope -1 and y-intercept -3.
Start at -3 on the y-axis and mark a point. Then from this point move down 1 unit and to the right 1 unit. Mark a point and connect.
This graph is represented in the picture attached.
