Answer: y=5x/2 - 2.5
Step-by-step explanation:
m=(v2-y1)/(×2-x1)
m=(-2.5-2.5)/(0-2)
m=-5/(-2)
m=5/2
y=mx+b
V=5x/2 + b
-2.5=5(0) /2 + b
-2.5=0 + b
b=-2.5
y=5x/2 - 2.5

Answer: y=5x/2 - 2.5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-2.5-2.5)/(0-2)

m=-5/(-2)

m=5/2

y=mx+b

y=5x/2 + b

-2.5=5(0)/2 + b

-2.5=0 + b

b=-2.5

y=5x/2 - 2.5

Solving Rational equations. LCD method. Show work. Image attached.

Answer:

$k=\frac{1}{2}$

Step-by-step explanation:

The given rational equation is

$\frac{5k}{k+2}+\frac{2}{k}=5$

The Least Common Denominator is

$k(k+2)$

Multiply each term by the LCD.

$k(k+2)\times \frac{5k}{k+2}+k(k+2)\times \frac{2}{k}=5k(k+2)$

Simplify;

$k\times \frac{5k}{1}+(k+2)\times \frac{2}{1}=5k(k+2)$

$\Rightarrow k(5k)+2(k+2)=5k(k+2)$

Expand;

$\Rightarrow 5k^2+2k+4=5k^2+10k$

Group similar terms;

$\Rightarrow 5k^2-5k^2+2k-10k=-4$

$\Rightarrow -8k=-4$

Divide by -8.

$k=\frac{1}{2}$

13. $9 because 75%=3/4 and 1/4 of 12 is 3, and so you multiply $3 by 3 to get $9
14. Multiply 325 by .2 to get $65.00
15. 15 minutes, because if it rises 2 feet every hour, then it rises 1 foot every hour, and so you divide that by 2 to get 15
Answers:
13. $9
14. $65.00
15. 15 mins
