Answer:
Step-by-step explanation:
y=f(x)=-5x
since x=3 just replace x with 3
y=f(x)=-5(3)
y=f(x)=-15
Answer:
∠A = ∠C = 60°
∠B = ∠D = 120°
Step-by-step explanation:
In quad. DPBQ, by angle sum property we have
∠PDQ + ∠DPB + ∠B + ∠BQD = 360°
60° + 90° + ∠B + 90° = 360°
∠B = 360° – 240°
Therefore, ∠B = 120°
But ∠B = ∠D = 120° opposite angles of parallelogram
As, AB || CD opposite sides of a parallelogram
∠B + ∠C = 180° sum of adjacent interior angles is 180°
120° + ∠C = 180°
∠C = 180° – 120° = 60°
Hence ∠A = ∠C = 60° Opposite angles of parallelogram are equal
They are accepted values.
They are neither accurate nor precise.
So the answer is D.
A. -2.5+3.5n is the answer
2 to the second power and 2 squared are the same number
they both are 2^2
