You give up a full-time salary of $40,000 a year to go to school for 2 years. The total cost of going to school is $30,000. If y

Xelga [282]

Answer:

$68,000

Step-by-step explanation:

we have to determine the total economic costs of going to college = ($40,000 x 2) + ($30,000 x 2) = $140,000

since we want to recover our "college investment" in 5 years or less, then we must earn at least $140,000 / 5 = $28,000 more per year

the minimum salary that we should earn after graduating = $40,000 (our current salary) + $28,000 (to recover college costs) = $68,000

What is the slope of a line perpendicular to the line passing through E(-1,6) and F(-2,-10)?

STatiana [176]

Answer:

Step-by-step explanation:

E(-1,6) & F(-2,-10)

$Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\ \ \ \ = \frac{-10-6}{-2-[-1]}\\$

$=\frac{-10-6}{-2+1}\\\\=\frac{-16}{-1}\\\\= 16$

Slope of the line perpendicular to this line = -1/m = -1/16

Given : 11x – 6y = –1; x = 8

Natasha_Volkova [10]

Answer:

B. a. Given; b. Substitution Property; c. Subtraction Property of Equality; d. Division Property of Equality; e. Symmetric Property of Equality

Step-by-step explanation:

Given expression,

$11x - 6y = -1; x = 8$

By substituting x = 8,

$11(8) - 6y = -1$

$88 - 6y =-1$

By subtraction property of equality,

$-6y = -89$

Division property of equality,

$y = \frac{89}{6}$

By symmetric property of equality,

$\frac{89}{6} = y$
