Answer:
(-12,6)
Step-by-step explanation:
using elimination method multiply the second equation by -1
18x - 16y = -312
-78x + 16y = -408
add the two equations
60x = -720
divide by 60
x = -12
plug -12 into the first equation
18(-12) - 16y = -312
-216 - 16y = -312
-16y = -96
y = 6
The x intercept is (-10, 0)
Sin=opposite/hypotenuse
The opposite of B is 3 and the hypotenuse is 5.
Therefore the answer for 1 is D 3/5.
cos=adjacent/hypotenuse
The adjacent of B is 4 and the hypotenuse is 5.
Therefore the answer for 2 is B 4/5.
