L 5.2.3 Quiz: Two-Variable Systems: Substitution

Misha Larkins [42]

Answer:

We get x=3 and y=21

The ordered pair will be: (3,21)

Step-by-step explanation:

We need to use the substitution method to solve the system of equations.

$y = 10x-9\\y = x + 18$

For substitution method we substitute the value of x or y from one equation to other.

Let:

$y = 10x-9--eq(1)\\y = x + 18--eq(2)$

Putting value of y from equation 2 into equation 1

$y=10x-9\\Put\:y=x+18\\x+18=10x-9\\x-10x=-9-18\\-9x=-27\\x=\frac{-27}{-9}\\x=3$

So, we get value of x=3

Now, for finding value of y, We substitute the value of x

Find value of x from equation 2

$y=x+18\\x=y-18$

Now, putting value of x in equation 1

$y=10x-9\\Put\:x=y-18\\y=10(y-18)-9\\y=10y-180-9\\y-10y=-189\\-9y=-189\\y=\frac{-189}{-9}\\y=21$

So, we get value of y=21

So, We get x=3 and y=21

The ordered pair will be: (3,21)

Which of the following inequalities matches the statement below: X is greater than or equal to 10

ivolga24 [154]

Step-by-step explanation:

x is greater than or equal to 10.

x ≤ 10 and x < 10 options are incorrect, x is not less than 10.

x > 10 is incorrect, x can be greater but x can be equal to 10 as well.

X ≥ 10 is correct. x is greater than or equal to 10.

> - Greater Than.

< - Less Than.

≥ - Greater Than or Equal to.

≤ - Less Than or Equal to.
