If x^2+y^2=73 and xy=24, what is the value of (x+y)^2? And Why?

1 answer:

7 0

(x+y)^2=x^2+y^2+2xy=73+2*24=73+48=121

⇒ (x+y)^2=121

Let's solve ~

$\qquad \sf \dashrightarrow \: \cfrac{1}{b} + 10 = \cfrac{9}{b} + 7$

$\qquad \sf \dashrightarrow \: \cfrac{9}{b} - \cfrac{1}{b} = 10 - 7$

$\qquad \sf \dashrightarrow \: \cfrac{8}{b} = 3$

$\qquad \sf \dashrightarrow \: b = \cfrac{8}{3}$

$Find \ \frac{1}{5} \ of \ \$2,325.35
\\\ 2325.35/5 = 465.07
\\\ 465.07*2 = 930.14
\\\ 2325.35- 930.14 = 1395.21
\\\ \boxed{1395.21}$

Answer:

Step-by-step explanation:

You can see from the graph that everytime x goes up by 1, y goes down by 4, so the slope is -4.

The y-intercept is at -1

This means that the equation would be C. y = -4x - 1
