Hope this helps
Answer:
A
Step-by-step explanation:
The x-intercepts are the roots of a parabola. Specifically, when a parabola is in the form
, where h and k are real numbers, the roots are
and
.
Our parabola has a plus, though. That's a problem, right?
No!
, so there's no problem. So, our roots are
and
.
So, the answer is A and we're done!

Step-by-step explanation:
<u>First Degree Equations</u>
A first-degree equation can have one, none, or infinitely many solutions.
An equation like
2x + 3 = -x + 6
Has one solution: x=1
An equation like:
4x + 2 = 4x + 1
Has no solutions because when trying to solve for x we get:
2 = 1
This equality is false and no value of x can make it true
Finally, the equation:
3x + 2 = x + 2x + 2
Has infiniteyl many solutions, because when trying to solve it, we get:
2 = 2
Which is true regardless of the value of x
- The first given equation:
3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation not having solutions, we should have 8x plus any number but 9 on the right side of the equation:
8x + 9 = 8x -3, or
8x + 9 = 8x + 4
- The second given equation:
3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
If the equation has one solution, the only condition is that we should not have 8x on the right side. Thus any of those will do:
8x + 9 = 3x + 9
8x + 9 = -x + 5
8x + 9 = 0
3x + 9 + 4x + x = ??
can be simplified as:
8x + 9 = ??
For this equation to have infinitely many solutions, the right side must be exactly equal to the left side:
8x + 9 = 8x + 9
<h3>Answer:</h3>
The attached shows a graph
<h3>Explanation:</h3>
A graphing calculator can graph this for you when you give it the equation.
For graphing by hand, it is helpful to recognize that the equation is in "slope-intercept" form. This means the constant term (-9) is the y-intercept, the point on the y-axis where the line crosses. Mark the point -9 on the y-axis. (The coordinates are (0, -9).
The slope is 5/3, the coefficient of x. This means the line goes up 5 units for every 3 units it goes to the right. The point that is 3 over and 5 up from (0, -9) is (0+3, -9+5) = (3, -4). Mark that point.
Draw a line through the marked points.
