Answer:
The coefficient of the squared term of the equation is 1/9.
Step-by-step explanation:
We are given that the vertex of the parabola is at (-2, -3). We also know that when the <em>y-</em>value is -2, the <em>x-</em>value is -5. Using this information we want to find the cofficient of the squared term in the parabola's equation.
Since we are given the vertex, we can use the vertex form:
Where <em>a</em> is the leading coefficient and (<em>h, k</em>) is the vertex.
Since the vertex is (-2, -3), <em>h</em> = -2 and <em>k</em> = -3:
Simplify:
We are also given that <em>y</em> = -2 when <em>x</em> = -5. Substitute:
Solve for <em>a</em>. Simplify:
Therefore, our full vertex equation is:
We can expand:
Simplify:
The coefficient of the squared term of the equation is 1/9.
Answer:
1 hour 6 minutes = 66 minutes.
Step-by-step explanation:
Starting the test at 2:34 pm,
Finishes the test 35 mins later, time = 2:34 pm + 35 mins = 3:09 pm
Then Kevin starts his practice at 4:15 pm
Time between time the test ended and when the practice started
= 4:15 pm - 3:09 pm = 1 hour 6 minutes = 66 minutes.
Hope this Helps!!!
650 cm when you convert it that is what i got it is correct
Answer:
The correct answer is x = 7.
Step-by-step explanation:
To solve this problem, our first step is to use the distributive property on the left side of the equation. This is modeled below:
-5x + 10 = -25
Next, we should subtract 10 from both sides of the equation.
-5x = -35
Finally, we should divide both sides of the equation by -5 to get the variable x alone on the left side of the equation.
x = 7
Therefore, the answer is x = 7.
Hope this helps!
