Is (x, y) a solution to the system of linear inequalities?

Full solution

Q. Is

(9,\,1)

a solution to this system of inequalities?

\newline

2x + 2y < 20

\newline

x + y \geq 10

\newline

Choices:

\newline

(A)yes

\newline

(B)no

Check Inequality: Check if $(9, 1)$ satisfies the first inequality 2x + 2y < 20. Substitute $x = 9$ and $y = 1$ . 2(9) + 2(1) < 20 18 + 2 < 20 20 < 20 Oops, that's not right, it should be $20$ is not less than $20$ .

Jack is fixing up his home and must spend less than

\$4,800

to hire carpenters and painters. Carpenters charge

\$60

per hour and painters charge

\$32

\newline

Select the inequality in standard form that describes this situation. Use the given numbers and the following variables.

\newline

x =

the number of hours of carpentry

\newline

y =

the number of hours of painting

\newline

\newline

32x + 60y < 4,800

\newline

60x + 32y < 4,800

\newline

32x - 60y < 4,800

\newline

60x - 32y < 4,800
