Answer: (2/5, 9/5)

Step by step explanation:

To find the solutions, we are given the value of y in terms of x: y = 2x + 1. We can plug this into the circle equation to get:

(x - 1)^2 + (2x + 1 - 1)^2 = 1

Now, we can expand and simplify:

x^2 - 2x + 1 + (2x)^2 = 1

x^2 - 2x + 1 + 4x^2 = 1

5x^2 - 2x = 0

Now, we can factor:

x(5x - 2) = 0

And, using the zero product property, we get two equations which we can solve:

x = 0

5x - 2 = 0

5x = 2

x = 2/5

Since x is 0 in the first solution, we use the other solution and plug it into the equation y = 2x + 1 to find y:

y = 2(2/5) + 1

y = 4/5 + 1

y = 9/5

This means the coordinates of the point is (2/5, 9/5)

Rewrite y = -(x + 2)2 – 5 in standard form.
xenn [34]

Answer:

y = - x² - 4x - 9

Step-by-step explanation:

Given

y = - (x + 2)² - 5 ← expand (x + 2)² using FOIL

  = - (x² + 4x + 4) - 5 ← distribute parenthesis by - 1

  = - x² - 4x - 4 - 5 ← collect like terms

   = - x² - 4x - 9 ← in standard form

The difference between 12 and ten times a number is -28
aev [14]

Answer:

<h2>4</h2>

Step-by-step explanation:

n-\text{the number}\\\\12-10n=-28\qquad|\text{subtract 12 from both sides}\\\\12-12-10n=-28-12\\\\-10n=-40\qquad|\text{divide both sides by (-10)}\\\\\dfrac{-10n}{-10}=\dfrac{-40}{-10}\\\\\boxed{n=4}

A triangular bandana has an area of 46 square inches. The height of the triangle is 5 3 4 inches. Enter and solve an equation to
shutvik [7]

Answer: 16 inches

Step-by-step explanation:

The area of a triangle = bh/2

where b = base = unknown

h = height = 5 3/4 inches

Area = 46 inches²

Therefore, 46 = base × 5 3/4 / 2

Cross multiply

46 × 2 = base × 5 3/4

92 = base × 5 3/4

Base = 92 ÷ 5 3/4

Base = 92 ÷ 23/4

Base = 92 × 4/23

Base = 4 × 4

Base = 16 inches
