-9x+4=-8-5x helppppp plsssss

Answers

Answer 1
Answer:

Answer:3

Step-by-step explanation:

-9x+4=-8-5x

-4x+4=-8

-4x=-12

x=3
Answer 2
Answer:

Answer:

Step-by-step explanation:

Add 5x so -9x+5x becomes -4x+4=-8 then subtract -4 and then -4+-8 becomes -12 and then solve for x which is -12/-4 which is 3.

Answers

Step-by-step explanation:

The options are not to clear, nevertheless let us model the expression for the cost.

Let y be the total cost

And x be the number of miles

Given that the fixed rate is $8 and $4 for each extra mile traveled

The total cost is

y=8+4x

For a 5 mile journey the cost is

y=8+4(5)

y=8+20

y=28

$28

Which of the following is the function representing the graph below? graph begins in the third quadrant near the line y equals negative 3 and increases slowly while crossing the ordered pair 0, negative 2. When the graph enters the first quadrant, it begins to increase quickly throughout the graph.f(x) = 4x
f(x) = 4x − 3
f(x) = 4x + 3
f(x) = 4(x + 3)

Answers

Answer:

  f(x) = 4^x -3

Step-by-step explanation:

All of the listed functions are linear functions with a constant slope of 4. None of them goes through the point (0, -2).

__

So, we assume that there is a missing exponentiation operator, and that these are supposed to be exponential functions. If the horizontal asymptote is -3, then there is only one answer choice that makes any sense:

  f(x) = 4^x -3

_____

The minimum value of 4^z for any z will be near zero. In order to make it be near -3, 3 must be subtracted from the exponential term.

Four books, one each on physics, chemistry, mathematics, and biology are about to be stacked on a shelf. If the books are stacked randomly, what is the probability the mathematics book is on top?

Answers

There are 4 books.
The math book can either be top, second from top, third from top, or on the bottom.
The probability of being in any single given position is 1/4 = 25% .
Since each book can be put on the top, and there are 4 books, the chances of a math book going on the top is 1/4, while the other 3 chances are the other books. So your answer is 1/4 or 0.25

If each phone charger costs 1$ to make, what price should the store charge to maximize its profit? If x is the number of times the price is reduced by one dollar. Find a function for total profit with respect to x. A negative value for x will mean the price is increased.
