An equation of the line that contains the origin and the point (1,2) is

Semmy [17]

(0,0)(1,2)......(0,0) is the origin
slope = (2-0) / (1-0) = 2/1 or just 2

y = mx + b
slope(m) = 2
(1,2)...x = 1 and y = 2
now we sub, we r looking for b, the y intercept
2 = 2(1) + b
2 = 2 + b
2 - 2 = b
0 = b

ur equation is : y = 2x + 0...or just y = 2x

How do I solve this equation and check the solutions?

bearhunter [10]

Answer:

{-6}

Step-by-step explanation:

Step 1 Raise both sides of the equation to the index of the radical in the case 2

$(\sqrt{2x+13} )^{2} =(x+7)^{2}$

$2x + 13 = (x+7)(x+7)$

$2x +13 = x^{2} + 14x + 49\\0=x^{2} +12x+36$

Step 2 Factor

(x + 6)(x + 6) = 0

x + 6 = 0

x = - 6

Step 3 Check -6

$\sqrt{2(-6)+13} = -6 + 7\\\sqrt{-12+13} = 1\\\sqrt{1} = 1\\1 = 1$

How tall is the tower?

Karo-lina-s [1.5K]

Answer:

93.6 ft

Step-by-step explanation:

$\bf \cfrac{AB}{BC} = \tan(60)$

$\bf \cfrac{x}{50} = \sqrt{50}$
$\bf x = 50 \sqrt{3}$

Length of tower:-

$\bf x + 7$
$\bf 50 \sqrt{3} + 7$
$\bf 93.6025$
$\bf = 93.6$

Therefore, the tower is 93.6ft tall.
