When x = -1
y + 5x = 6
y = 6 - 5x
y = 6 - (5)(-1)
y = 6 - (-5)
y = 11
when x = 0
y = 6 - 5x
y = 6 - (5)(0)
y = 6 - 0
y = 6
when x = 1
y = 6 - 5x
y = 6 - (5)(1)
y = 6 - 5
y = 1
The answer is 111
Calculate square root of 1 to get 1
Multiply 111 x 1
=111
The mistake is made on line 3, after calculating 35/7, he should have started with the multiplication 6(2)
Answer:
Assuming you mean (2^3)3, the answer is 24
Step-by-step explanation:
using pemdas you do 2 to the third power first
2x2=4 4x2=8
then you mutiply by the number not in parenthesis; 3
8x3 = 24
Answer:
True; quadrants I & IV
Step-by-step explanation:
We know the relation between sine and cosine function which is given by

Let us solve this equation for cosine function.

Take square root both sides. When ever we take square root we need to write the solution in plus minus form



If Θ is in quadrants I and IV then the value will be positive and if Θ is in II and III quadrant then the value is negative.
Hence, if Θ is in quadrants I & IV, then we have

Thus, the correct option is: True; quadrants I & IV
