Answer:
A
Step-by-step explanation:
We have the expression:
And we want to find its sign given that a>0 and b<0.
Notice that the expression is already negative since we have -4.
a>0 means that a is positive. Therefore, we can ignore it since it won’t do anything.
b<0 means that b is negative. Therefore, we will have two negatives being multiplied together. Hence, this will make a positive.
Therefore, the sign of our expression will be positive.
We can see this with an example. Let a=1 (1>0) and let b=-1 (-1<0). Then:
So, the sign is positive.
Hence, the answer is A.

The answer is
<h2>
</h2>
Step-by-step explanation:
To find the inverse of f(x) , equate f(x) to y
That's
y = f(x)
We have
Next interchange the terms that's x becomes y and y becomes x
<u>Next solve for y</u>
Move 3 to the other side of the equation
That's
<u>Divide both sides by 25</u>
We have the final answer as

Answer:
11.9 feet
Step-by-step explanation:
We want to find the value of 'x' and we are asked to set up an equation to find the value of x. In equation we must remember to get all the numerical values to one side and all the non-numerical values to the other while remembering to keep the equation balanced for example if we add 4 on one side we must do it to the other side to keep the equation balanced so,
→ x + 5.2 + 11.1 + 6.4 = 34.6
⇒ Simplify equation
→ x + 22.7 = 34.6
⇒ Minus 22.7 from both sides to isolate x
→ x = 11.9 feet
