Answer:
Its the third choice:
(2, 5).
Step-by-step explanation:
6x + 4y = 32
-6x + 4y = 8 Adding the 2 equations:
0 + 8y = 40
8y = 40
y = 5
Now substitute for y in the first equation:
6x + 4(5) = 32
6x = 32 - 20 = 12
x = 2.
Answer:
5.2y^3
Step-by-step explanation:
There are 3 y's which can be presented as y^3

Answer:
79.5
Step-by-step explanation:
a^2 =b^2+ c^2-2bc cos A
cos p = 73^2+35^2-75^2/2(73)(35)
cos p= 9229/5110
cosp=79.5
