Answer:
q = -2
Step-by-step explanation:
-2x²-8x = 10 (divide both sides by -2)
x² + 4x = -5 (Apply completing the square method)
x² + 4x + (4/2)²= -5 + (4/2)²
x² + 4x + 2²= -5 + 2² (reduce left hand side using a²+2ab+b² = (a+b)² )
(x+2)² = -5 +4
(x+2)² = -1
(x+2)² + 1 = 0 (multiply both sides by -2)
(-2)(x+2)² + 1 (-2) = 0
-2[x - (-2)]² + (-2) = 0 ---> compare this with -2(x-p)² + q = 0
We can see that p = 2 and q = -2
Answer:
The answer to this question is v= -4
For this case, the first thing we must do is define variables.
We have then:
x: time in minutes
y: distance traveled.
We then have the following equations:
For Kathleen:

For Arnob:

By the time Arnob reaches Kathleen we have:

From here, we clear the value of x.
We have then:


Answer:
it takes Arnob to catch up to Kathleen 75 minutes:
d. 75
Answer:
0>0 or error
Step-by-step explanation:
8m-2(14-m)>7(m-4)+3m
8m-28+2m>7m-28+3m
10m-28>10m-28
0>0
Explanation:
In a function, each x-value has <u>one</u> y-value.
___
That is the definition of a relation that is a function.
