<span>12x +3y = 12
y = -4x +5

We can convert the first equation to the same form as the second (y=mx+b, or slope-intercept).

12x +3y = 12
3y = -12x +12
y = -4x +4

Comparing the simplified first equation y = -4x +4 to the second equation y = -4x + 5, we see that both have the same slope (m = -4), but different y-intercepts (b = 4, b = 5). This means they are parallel lines, or an inconsistent system. There are no solutions.</span>

Wittaler [7]

Good evening

Answer:

Step-by-step explanation:

let Point M(x , y) be the midpoint of segment HK then

x = (8+10)/2 = 18/2 = 9

y = (13+9)/2 = 22/2 = 11.

if you see this I really need help on this question asap ty so much... "The flagpole in the diagram below has a height of 10ft.

aev [14]

Answer:

15.62 feet

Step-by-step explanation:

If the flagpole is 10ft tall and the shadow is 12ft long, and you need to find the distance from the top of the flagpole to the far end of the shadow, to get your answer, you must use the pythagorean theorum.

$a^{2} + b^{2} = c^{2}$

let height of flagpole = a

let length of shadow = b

let distance between the two = c

$10^{2} + 12^{2} = c^{2} \\100 + 144 = c^{2}\\244 = c^{2}\\\sqrt{244} = \sqrt{c^{2}} \\\sqrt{244} = c\\15.62 = c$
