Answer:
The value of x is: x > -2
Step-by-step explanation:
The interval notation if you need it is (-2, ♾)
Answer:
Again, the answer is (1,-2)
Step-by-step explanation:
Substitute the values
Answer:
(2, 0)
Step-by-step explanation:
X intercept is when y = 0.
0 = -10 + 5x
5x = 10
x = 2
Okay first off. You want to combine like terms.
2.75-1.5=1.25j
2.25+3=5.25
Now you just fit those two answers into the final answer and you have:
1.25j+5.25.
Answer:
40°
Step-by-step explanation:
Every triangle adds up to 180°
So to get the angle of the triangle we already have two values of:

Then since it's at a 90° angle we can subtract 50 to get:
40° as the other part of the right angle.
And applying the 180 rule again:
