Answer:
x -y = -5
3x +y = -11
Step-by-step explanation:
We assume you want two linear equations. Since you know a point on each line, the only thing you need to choose is the slope of the two lines through that point. We can make the slopes be +1 and -3, for example. Then the point-slope equations are ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -1 = +1(x +4)
y -1 = -3(x +4)
We can use these equations "as is", or put them in whatever form you like. I personally prefer "standard form:" ax+by=c.
<u>First equation</u>:
y -1 = x +4 . . . . . . eliminate parentheses
-5 = x -y . . . . . . . keep positive x term, put x and y together, separate from the constant
x - y = -5 . . . . . . standard form
<u>Second equation</u>:
y -1 = -3x -12 . . . . eliminate parentheses
3x +y = -11 . . . . . . add 3x+1 to both sides

but don''t quote me on it
It looks like you have number 1 correct.
For number 2, what is alike is the exponent of 2. To combine them, add them together. You can do this because they are like terms (aka have the same variable and exponent)
3-4-1= -2. The answer is -2x^2
For number 3, those are not like terms. They either do not have the same variable (x or y) or they do not have the same exponent (1 or 2)
Both the exponent and the variable have to be the same for it to be a like term.
Answer:
The second water balloon is in the air longer. Balloon 1 will reach the maximum height faster because it is lower.
Step-by-step explanation:
This is because you drop the first balloon at a height of 105 ft. The second balloon is dropped at a height of 125 ft. The second balloon stays in the air longer because it was dropped at a higher elevation. Balloon 1 will reach the maximum height faster because it is lower.
If this answer is correct, please make me Brainliest!
On my graph, the black line is the equation for Balloon 1 and the red line is the equation for Balloon 2. Since the black line has a lower maximum, this means that Balloon 1 will reach its maximum first.
