ANSWER
a=9
EXPLANATION
The given quadratic equation is

If x=1 is a solution, then it must satisfy this equation:



Therefore the value of 'a' is 9
Answer:
Step-by-step explanation:
<u>Let the integers be x- 1, x and x +1, then:</u>
- x - 1 + x + x + 1 = 87
- 3x = 87
- x = 29
The integers are 28, 29, 30
The correct answer is. v=25/2
Answer:
<em>x = 9</em>
Step-by-step explanation:
Vertical angles are congruent, so their measures are equal.
4x + 6 = 7x - 21
Subtract 7x from both sides.
-3x + 6 = -21
Subtract 6 from both sides.
-3x = -27
Divide both sides by -3.
x = 9
If you divide by 8, you can put the equation into intercept form. That form is ...
... x/a + y/b = 1
where <em>a</em> and <em>b</em> are the x- and y-intercepts, respectively.
Here, your equation would be
... x/(-2) + y/(-4) = 0
The graph with those intercepts is not shown with your problem statement here. See the attachment for the graph.
