Answer:

x = 3/5√10

y = 2√10

Step-by-step explanation:

using the Pythagorean theorem:

y² = 7² - 3² = 49 - 9

y² = 40

y = 2√10

3/4.5 = y/5x

4.5y = 15x

substitute for y:

4.5(2√10) = 15x

15x = 9√10

divide both sides of the equation by 15:

x = (9√10)/15 = 3/5√10

I’m honestly confused on how to solve for k. please help.

stellarik [79]

Answer:

k=9

Step-by-step explanation:

$slope = \frac{y2 - y1 }{x2 - x1} \\ \frac{ - 5}{2} = \frac{ - 11 - k}{6 - ( - 2)} \\ - ( \frac{5}{2} ) = - ( \frac{11 + k}{8} ) \\ \frac{5}{2} = \frac{11 + k}{8} \\ 5 \times 8 = 2(11 + k) \\ 40 = 22 + 2k \\ k = \frac{40 - 22}{2} \\ k = 9$

10(a-2.5+0.56b) is this equivalent to 10a - 25+56b

kirill115 [55]

Hey there!

10(a - 2.5 + 0.56b)

= 10(a) + 10(-2.5) + 10(0.56b)

= 10a - 25 + 5.6b

= 10a + 5.6b - 25

Therefore, your answer is: 10a + 5.6b - 25

Good luck on your assignment and enjoy your day!
