Answer:
(5x+1)(2x+1)(x+4)
Step-by-step explanation:
The factored from of a polynomial can be found from the zeros or x-intercepts of the graph.
The x-intercepts here are x= -1/5, x=-1/2 and x= -4. You can find the factors by finding the expression which solves for each value.
Since x = -1/5 then the factor is 5x+1.
Since x = -1/2 then the factor is 2x+1.
Since x = -4 then the factor is x+4.
So the factored form is (5x+1)(2x+1)(x+4).
Answer is
x > 5

Answer: A
Step-by-step explanation:
The first thing we need to do is to make sure our equation is in standard form. The given equation is not in standard form.
3x²-2x=0
Now that the equation is in standard form, we can find our A, B, C to see which quadratic equation is correct.
A=3
B=-2
C=0
We can automatically eliminate D because the first value is -3 when it is supposed to be -(-2). Also, the denominator is supposed to be 2a. We know that A=3. The denominator should be 2(3), not 2(-2).
Next, we can eliminate B and C. For the 4ac, we know it has to be 4(3)(0) because A=3 and C=0. B and C have given 4(3)(2) and 4(3)(1), respectively. This does not match A=3 and C=0.
Therefore, A is the correct answer.
Answer:
<u>B. (3,25)</u>
Step-by-step explanation:
x = level of the video game
y = number of points
At level 1, a player has 5 points.
At level 2, the player has 5 + 10 = 15 points
Therefore, we can use the function notation this way:
f(x) = 5x + 10
<u>The only ordered pair given that is from this function is:</u>
<u>B. (3,25)</u>
<u>f(3) = 5 * 3 + 10 </u>
<u>f(3) = 15 + 10 = 25</u>
The remaining three don't represent this function.
Answer:
average acceleration a=change in velocity / time it took to get to velocity
a=(45-0)mph / 2s = 22.5 mph/hr/s
