-3z^7 - (-5z^7) = -3z^7 + 5z^7 = 2z^7
<u>Answer:</u>
<u>
</u>
<u>Step-by-step explanation:</u>
From the graph, we can see that y = -1 when x = 0.
So to check whether which of the given options is the equation of the given graph, we will set our calculator to the radian mode and then plug the value of x as 0.
1. y = cos(x + pi/2) = cos(0 + pi/2) = 0
2. y = cos(x+2pi) = cos(0+2pi) = 1
3. y = cos(x+pi/3) = cos(0+pi/3) = 1/2 = 0.5
4. y = cos(x+pi) = cos(0+pi) = -1
Therefore, the equation of this graph is y = cos(x+pi) = cos(0+pi) = -1.
Answer:
A. 3
Step-by-step explanation:
The answer would be A because 3 times 3 is 9 and 9-4=5 which is the value o f y. 3x-4=5
add 4 to both sides: 3x=5+4
simplify: 5+4=9
divide both sides by 3: x= 9/3
simplify 9/3 to 3:
x= 3
