Answer:

1) slope = 3, y-intercept = 1

2) slope = -4, y-intercept = 140

Step-by-step explanation:

to find the slope take rise over run, for y-intercept its always where ever the 0 falls on the x line.

1) since the rise(y) = 6, and the run(x) = 2, it becomes 6/2 making your answer 3. They y-intercept is x = 0, y = 1.

2) The rise(y) = -20, and the run(x) = 5, it becomes -20/5 making your answer -4. The y-intercept is x = 0, y = 140.

The park shown is in the shape of a square. Is the perimeter rational or irrational? Area = 24,200 yd 2

romanna [79]

Answer:

Perimeter is irrational

Step-by-step explanation:

The attachment is missing but the question is still answerable

Given

$Area = 24200 yd^2$

Required

Determine if the Perimeter is rational or not

First, we need to determine the sides of the square;

$Area = Length * Length$

Substitute $Area = 24200 yd^2$

$24200 = Length * Length$

$24200 = Length^2$

Take Square root of both sides

$\sqrt{24200} = Length$

$Length = 155.563492$

The perimeter of a square is calculated as:

$Perimeter = 4 * Length$

$Perimeter = 4 * 155.563492$

$Perimeter = 622.253968$

Because the value of perimeter can't be gotten by dividing two integers, then perimeter is irrational

Quick I need an answer to this Queston:

fiasKO [112]

Step-by-step explanation:

$- \frac{3}{4} x + 2 \frac{1}{4 } = \frac{1}{2} x + 1$

$- \frac{3}{4} x + \frac{9}{4} = \frac{1}{2} x + \frac{2}{2}$

$\frac{ - 3x + 9}{4} = \frac{2x + 4}{4}$

$- 3x + 9 = 2x + 4$

$- 3x - 2x = 4 - 9$

$- 5x = - 5$

$x = \frac{ - 5}{ - 5}$

$x = 1$

The answer is C.

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] cosθ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Define

Angle θ = x

Adjacent Leg = 5.8

Hypotenuse = 7.3

Step 2: Solve for x

Substitute in variables [Cosine]: $\displaystyle cosx^\circ = \frac{5.8}{7.3}$
[Fraction] Divide: $\displaystyle cosx^\circ = 0.794521$
[Equality Property] Trig inverse: $\displaystyle x^\circ = cos^{-1}(0.794521)$
Evaluate trig inverse: $\displaystyle x = 37.39^\circ$
Round: $\displaystyle x \approx 37.4^\circ$
