Answer:
see below. The solution is the doubly-shaded area.
Step-by-step explanation:
Each boundary line will be dashed, because the "or equal to" case is <em>not included</em>. Each shaded area will be above the corresponding boundary line because the comparison symbol is y > .... That is, only y-values greater than (above) those in the boundary line are part of the solution.
Of course, the boundary lines are graphed in the usual way. Each crosses the y-axis at the value of the constant in its equation. Each has a slope (rise/run) that is the value of the x-coefficient in the equation.
Since <span> sin(α) > 0 and cos(α) > 0
so </span><span>α is IN THE FIRST QUADRANT (I)</span>
Answer:
4a³+3a-3
Step-by-step explanation:
You can solve this by combining like terms. Add the numbers with the correct exponents together.
-a³+5a³
4a-a
Thus, the answer is
4a³+3a-3
I am not entirely sure but I think the answer would be 60
Answer:
−25 is 25 units to the left of zero on a number line and
The opposite of −25 is 25 units to the right of zero on a number line.
Step-by-step explanation:
- a line on which we have numbers from negative infinity till positive infinity is a number line.
- so, it will obviously have 0 in the middle.
- in the left we will have negative numbers and on the right of 0 we will have positive numbers.
- the magnitude of the numbers will be increasing from 0 on both the sides.
- see the uploaded image in the attachment for better understanding.
- so, by seeing the image in attachment, we can say that,
−25 is 25 units to the left of zero on a number line and
The opposite of −25 is 25 units to the right of zero on a number line.
here, opposite of -25 refers to +25, which will be 25 units to the right of zero on a number line.
