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

Full solution

Q. Is

(1,\,5)

a solution to this system of inequalities?

\newline

9x + 2y < 20

\newline

14x + y \geq 20

\newline

Choices:

\newline

(A)yes

\newline

(B)no

Check First Inequality: Check if $(1, 5)$ satisfies the first inequality 9x + 2y < 20. Substitute $x = 1$ and $y = 5$ into the inequality. 9(1) + 2(5) < 20 9 + 10 < 20 19 < 20, which is true.
Check Second Inequality: Check if $(1, 5)$ satisfies the second inequality $14x + y \geq 20$ . $\newline$ Substitute $x = 1$ and $y = 5$ into the inequality. $\newline$ $14(1) + 5 \geq 20$ $\newline$ $14 + 5 \geq 20$ $\newline$ $19 \geq 20$ , which is false.

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
