Answer:

1 11/12

Step-by-step explanation:

Simplify 3\times 43×4 to 1212.

\frac{12+1}{4}-1\frac{1}{3}

12+1

−1

3 Simplify 12+112+1 to 1313.

\frac{13}{4}-1\frac{1}{3}

−1

4 Convert 1\frac{1}{3}1

to improper fraction. Use this rule: a \frac{b}{c}=\frac{ac+b}{c}a

ac+b

5 Simplify 1\times 31×3 to 33.

13/4 -3 +1 / 3

6 Simplify 3+13+1 to 44.

13/4-4/3

7 (Find the Least Common Denominator (LCD) of 13/4,4/3 In other words, find the Least Common Multiple (LCM) of 4,34,3.)

LCD = 1212

8 (Make the denominators the same as the LCD)

13 x 3 - 4 x 4

4 x 3 -3 x4

9 (Simplify. Denominators are now the same.)

39/12-16/12

10 (Join the denominators.)

39-16

39−16

11 Simplify.

23/12

12 (Convert to mixed fraction.)

1 11/12

Pls help i will give u brianliest

Fynjy0 [20]

Answer:

Slope = -3

y-intercept = (0,-4)

Equation: y = -3x-4

Step-by-step explanation:

We can take any two input-output pairs from the table to find the equation of given function.

Linear function is given by:

$y =mx+b$

Here m is the gradient of the functions which is defined as:

$m = \frac{rise}{run} = \frac{y_2-y_1}{x_2-x_1}$

The input-output pairs are:

(x1,y1) = (-1,-1)

(x2,y2) = (0,-4)

First of all,

$m = \frac{-4-(-1)}{0-(-1)}\\= \frac{-4+1}{1} = -3$

Putting the value of slope in the equation

$y = -3x+b$

Putting (-1,-1) in the equation

$-1 = -3(-1)+b\\-1 = 3+b\\b = -1-3\\b = -4$

The equation will be:

$y = -3x-4$

Hence,

Slope = -3

y-intercept = (0,-4)

Equation: y = -3x-4

Una funzione inversamente proporzionale è rappresentata da?

puteri [66]

Supponiamo che due variabili x e y siano inversamente proporzionali; allora possiamo rappresentarli come x ∝ 1 / y. Ciò significa che se il valore di x aumenta, il valore di y diminuisce e viceversa.

Suppose two variables x and y are inversely proportional; then we can represent them as x ∝ 1/y. That means, if the value of x increases, then the value of y decreases and vice versa.
