Determine the intercepts of the line.

sergey [27]

Answer:

y-intercept: (0, 5/2)

x-intercept: (5/3, 0)

Step-by-step explanation:

The y-intercept is found by setting x=0 and dividing by the coefficient of y.

0 +2y = 5

y = 5/2

The x-intercept is found by setting y=0 and dividing by the coefficient of x.

3x +0 = 5

x = 5/3

The intercepts are ...

y-intercept: (0, 5/2)

x-intercept: (5/3, 0)

Hello!

<u><em>Answer: ⇒⇒⇒⇒⇒⇒⇒ =54</em></u>

_________________________________________________________________

Step-by-step explanation:

First you had to convert element to fraction.

$\frac{2}{3}*\frac{81}{1}$

Then you had to cross out by the common factor of 3.

$\frac{2}{1}=\frac{27}{1}$

Multiply by the fraction.

$\frac{2*27}{1*1}$

Multiply by the number.

$2*27=54$

$=\frac{54}{1*1}$

Again multiply by the number.

$1*1=1$

$=\frac{54}{1}$

Apply rule.

$\frac{54}{1}=54$

54 is the right answer.
