Answer:
k=-1
Step-by-step explanation:
-2=k. 2
Diving whole equation by 2
-2/2=k
k=-1
Answer:
50.04 pounds
Step-by-step explanation:
If 1 gallon weighs 8.34 pounds,
all you have to do is multiply 8.34 by 6
to get what 6 gallons would weigh.
Every week he withdraws $35 from the $950 in his savings, and he wants at least $600 by the end of the summer. So we could write:

Where 'x' is the number of weeks. Now let's solve it for 'x'.
Subtract 950 to both sides:

Divide -35 to both sides, don't forget to switch the sign when dividing/multiplying by a negative number:

So he can only withdraw at money for at most 10 weeks if he wants at least $600 left in his account.
Answer:
(B). between 2.5 and 3.0 and between 4.0 and 4.5.
Step-by-step explanation:
According to the Question,
- If the value of the function is 0 at x=c, then c is a root or zero of the function. It means the graph of function intersects the x-axis at its zeroes.
From the given table it is clear that the value of function are
x | f(x) | Sign
2.0 | 2.8 | Positive
2.5 | 1.1 | Positive
3.0 | –0.8 | Negative
3.5 | –1.2 | Negative
4.0 | –0.3 | Negative
4.5 | 0.7 | Positive
- The sign of values of function changes in interval 2.5-3.0 and 4.0-4.5. It means the graph of function must intersect the x-axis in intervals 2.5-3.0 and 4.0-4.5. So, the zeros of the function lie between 2.5 and 3.0 and between 4.0 and 4.5.
Therefore, the correct option is B.
