(x-1)² = 50
x-1 = <span>±</span>√50

x-1 = -5√2   or   x-1 = 5√2
x = 1-5√2          x = 1+5√2

(x-1)²=50
Square root both side
√(x-1)²=√50
x-1=±√50
Add 1 to each side
x-1+1=1±5√2
x=1±5√2 is your correct answer and if you want me to solve it, here will be the answer.
x=1±5√2
x=1+5√2
x≈8.1

x=1-5√2
x≈-6.1. Hope it help!

Option D:

The solution to the equation is y = 27.

Solution:

Given equation:

$\frac{1}{3} y=9

To solve this equation:

$\frac{1}{3} y=9

Multiply by 3 on both sides of the equation.

$3 \times \frac{1}{3} y=9 \times 3

3 in the numerator and denominator get canceled.

y = 9 × 3

y = 27

The solution to the equation is y = 27.

Option D is the correct answer.

Answer:

C. \frac{12}{7}

Step-by-step explanation:

To find the slope when you know two points, use this formula:

M = y₂ - y₁ ÷ x₂ - x₁

M = (4 - (-8)) ÷ (0 - (-7))

M = 12 ÷ 7

M = \frac{12}{7}

Hope that helps.

18 dollars - 4 dollars for the drink = 14 dollars after you take out the drink
$14 divided by 7 candy bars = $2 per candy bar

Answer:

  (B)  26°

Step-by-step explanation:

The angle at A made by the radius and the tangent is 90°. The angle at O is the same as arc AB, 64°. The acute angles in a right triangle are complementary, so the angle at C is the complement of 64°.

∠ACB = 90° -64°

∠ACB = 26°
