A
Explanation: You want to get x by itself. So add +7 to -7 to cancel it out, do the same thing to 4.
x-7=4
+7+7
x=11
x
Answer:
9 7/8 - ( -2 4/5 - 1/2) = 13.175
Step-by-step explanation:
Hope this is correct and helps.
Answer:
D is your answer
Step-by-step explanation:
y = x - 3
y = 2
x = 5
now insert the x and y into the equation
2 = 5 - 3
then subtract
2 = 2
last to find out if your right when both numbers equal each other like 2 = 2 then that will be you answer to your problem
When tan theta = 1 theta = 45 degrees in the first quadrant.
When its = -1 one value of theta is -45 degrees.
Also as the tangent is negative in the second quadrant theta can also be 135 degrees or - 225 degrees.
in fourth quadrant we have 315 degrees.
Its not 225 degrees because the tangent is positive in 3rd quadrant.
Correct answer is a, b, c and e.
