Answer:

\underline{\boxed{x =  \frac{A_r}{AC}}}

Step-by-step explanation:

let \: the \: area \: be \to \: A_r \\  since \: the \: base =AC \\ then \: the \: height = AB \\ but \: AB = 2x \\ hence : the \: area \: A_r=  \frac{1}{2} AC(2x) \\ (2x)AC = 2A_r\\ x =  \frac{2(A_r)}{2(AC)}  \\  \boxed{x =  \frac{A_r}{AC}}

Find the missing value so that the line passing through the points has the given slope.
Dominik [7]

Answer:

y = 2

Step-by-step explanation:

use slope formula:

(4 - y) / (3 - 10) = -2/7

4-y / -7 = -2 /7

cross-multiply:

7(4 - y) = (-7)(-2)

28 - 7y = 14

-7y = -14

y = 2
