Answer:
C. 192 1/2 in^2.
Step-by-step explanation:
Split this up anto 1 triangle and one rectangle
Area of the triangle = 1/2 * base * height
Its height = 36 - 25 = 11, and the base = 2 1/4 + 2 1/4 + 5 1/2= 10.
So it's area = 1/2 * 10 * 11 = 55.
Area of rectangle = 25 * 5 1/2 = 137 1/2.
Total area of the arrow = 55 + 137 1/2 = 192 1/2 in^2.
Answer:
Option D: (8, -12) is the solution set for given system.
Step-by-step explanation:
Given that:
1/4x-1/2y=8 ----------- eq1
1/2x+3/4y=-5 --------- eq2
Multiplying eq1 by 2 we get:
1/2x - y = 16 ------- eq3
Now by subtracting eq3 from eq2 we get:
(1/2x+3/4y) - (1/2x - y ) = -5 -16
By simplifying:
3/4y + y = -21
By taking LCM to make denominator same:
3/4y + y*4/4 = -21
3+4 / 4y = -21
7/4y = -21
Multiplying both sides by 4/7 we get
y = -21 * 4/7
y = -12
Putting value of y in eq3
1/2x - (-12)= 16
1/2x + 12 = 16
1/2x = 16 - 12
1/2x = 4
Multiplying both sides by 2
x = 4*2
x = 8
So the solution set = (8, -12)
i hope it will help you!
