Which statement must be true? a b c d

lozanna [386]

ANSWER

$\boxed {m \ne0}$

EXPLANATION

The given function is

$f(x) = mx + b$

We need to find the inverse of this function,

Let

$y= mx + b$

We interchange x an y to obtain,

$x = my + b$

We solve for y now to obtain,

$x - b = my$

We divide through by m to get,

$\frac{x - b}{m} = y$

Hence the inverse function is ,

${f}^{ - 1} (x) = \frac{x - b}{m}$

For this inverse to exist, the denominator must not be equal to zero,

Thus

$m \ne0$

The correct answer is A.

velikii [3]

Answer:

-4y^3 + 4y^2 - 6y + 25

Step-by-step explanation:

Step 1: Distribute the plus

(-4y^3 – 5y +16) + (4y^2 – y + 9)

-4y^3 - 5y + 16 + 4y^2 - y + 9

Step 2: Combine like terms

-4y^3 - 5y + 16 + 4y^2 - y + 9

-4y^3 + 4y^2 - 6y + 25

I don't get this answer someone plz help out

tangare [24]

1) we calculate the total cost of all items:

Total cost=27 * $1.25 + 5 *1.99$ + 1*1.5$=$33.75 + $9.95 + $1.5=$45.2

2)we express the total cost in cents:
$1=100 cents

$45.2=$45.2 * (100 cents /$1)=4520 cents.

3)we divide 4520 cents among the number of pupils

Each student will pay=4520 cents / 26 =173.84... cents≈174 cents.

Answer: Each student will pay 174 cents.
