Answer: y= -1/2x + 3.5
Step-by-step explanation:
y=mx+b
Y-3= -1/2(x-1)
y-3= -1/2x+1/2
+3 +3
y= -1/2x + 3.5
Answer: 5
Step-by-step explanation: Convert any mixed numbers to fractions.
Then your initial equation becomes: 1/4 x 20/1
Applying the fractions formula for multiplication,
=1/4 x 20/1 = 20/4
Simplifying 20/4, the answer is
=5
Answer:
D. -cos(nw0t)
Step-by-step explanation:
Subtracting 90° from the argument of the sine function shifts its graph 90° to the right, putting the negative peak on the y-axis. That corresponds to the negative cosine function, choice D.
20 x 1.0 = 20 Therefore,
20 x 0.7 = 14
