2.3+3.1+1= 6.4
25÷6.4= 3.90625
3 tasks can be completed in 25 minutes.
you can use both either (4tanA+3) or, (4tanA-3)
hope this helped you ☺️
any confusion comment it and let me know.

Answer: all real numbers greater than or equal to -3</h3>
Explanation:
The left-most point is at (-3,-2). The x coordinate is all we're concerned with here. The x coordinate for this point is x = -3. This is the smallest x value possible as an input. We cannot have x = -4 as that is nowhere on the blue curve.
So the domain is the set of real numbers x such that x is -4 or larger
In set builder notation, that would look like ![\{x|x\in\mathbb{R}, \ x \ge -3\}](https://tex.z-dn.net/?f=%5C%7Bx%7Cx%5Cin%5Cmathbb%7BR%7D%2C%20%5C%20x%20%5Cge%20-3%5C%7D)
In interval notation, we would say
to indicate to the reader "have an interval from -3 to positive infinity; include the endpoint -3"
2.1x + 4.2y = 14.7 is the same as x + 2y = 7 (divide both sides by 2.1)
-5.7x-1.9y=-11.4 is the same as 3x + y = 6 (divide both sides by -1.9)
Rearrange the first equation to get x = 7 - 2y and substitute into the second equation, 3(7 - 2y) + y = 6, 21 - 6y + y = 6, 5y = 15, y = 3
Substitute y = 3 into the first equation x + 2(3) = 7, x = 1
x = 1 and y = 3
Answer:
A
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis has the form
x = c
where c is the value of the x- coordinates the line passes through.
The only option in this form is
x = - 2 → A
