Answer:
x = 2
,
y = −
3
Step-by-step explanation
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form: (
2
,
−
3
)
Equation Form: x = 2
,
y = −
3
7x / 8 = 21
7x = 8*21
x = 24
Suppose y varies inversely with x and that y=2 when x=8 What is an equation for this inverse variation?
B. y= 2/8x
Answer: C
Exp:
∠DXC = 90°
∠CXB = 90°
supplementary = 180°
90+90= 180
