“3 less than the quotient of y and 4”

Bingel [31]

Answer:

Expression:

$\dfrac{y}{4}-3$

Value where y = 20

Step-by-step explanation:

Let's take a look at the sentence:

3 less than the quotient of y and 4

3 less indicates that you will subtract

- 3

Quotient means the result of division.

$\dfrac{y}{4}$

So if we combine the two, it says 3 less than the quotient so we subtract 3 from the quotient:

$\dfrac{y}{4}-3$

So if y = 20, we just substitute the y with 20

$\dfrac{y}{4}-3$

$\dfrac{20}{4}-3$

$5-3=2$

Y=2x−1

lord [1]

Answer:

(1,1) is a solution of the system.

Step-by-step explanation:

Let's solve the system.

y = 2x - 1

5x - 4y = 1

In the first equation, y is already separated as a function of x. So we replace in the second equation;

5x - 4(2x - 1) = 1

5x - 8x + 4 = 1

4 - 1 = 8x - 5x

x = 1

y = 2x - 1 = 2(1) - 1 = 1

(1,1) is a solution of the system.
