Answer:
a-2
Step-by-step explanation:
3a+3-2a-5
like terms must be together hence
3a-2a=a
3-5=-2
ans ;a-2

Step-by-step explanation:this is an example and then the question you can answer
Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.
another example
In order to be parallel to your line, a line has to have the same slope as your line. So it has to have slope −4. Thus any line parallel to the line y=−4x+5 has an equation of the form y=−4x+b, where b is any number.
I think it’s y=2 bu I’m not fully sure
<h3>25/8 or 3.125 seconds</h3>
To find the time until the ball hits the ground, you need to solve the quadratic as the height equals zero.
0 = -16t^2+50t
This gives us a classing quadratic that you can factor or use the quadratic formula to solve.
x = 0, x = 25/8
If you graph this, think of y = 0 as the ground, so when the parabola intersects the x-axis on the right that represents how much time would have passed.
Hope this helps you out! Good luck with your homework! Stay safe and stay healthy.
