Slope = -1/4
(4, 7)

y - 7 = -1/4 (x - 4)
y - 7 = -1/4x + 1
y = -1/4 + 8

answer is C

Mkey [24]

Answer:

∠ p ≈ 59°

Step-by-step explanation:

Using Pythagoras' identity in right triangle ABD to find DB

DB² = 5² + 6² = 25 + 36 = 61 ( take square root of both sides )

DB = \sqrt{61}

---------------------------------------

Using the cosine ratio in right triangle DBC

cos p = \frac{adjacent}{hypotenuse} = \frac{DC}{DB} = \frac{4}{\sqrt{61} } , thus

p = cos^{-1} ( \frac{4}{\sqrt{61} } ) ≈ 59°

A ramp leads up to a building. The top of the ramp is 5 feet above the ground, and the bottom is 15 feet from the building as sh
kirill [66]
To answer this you have to use Pythagoras's theorem: a^2 + b^2 = c^2

Put in the values:
5^2 + 15^2 = c^2

Simplify it:
25 + 225 = c^2

Simplify again:
250 = c^2

Square root both sides:
15.8113883008 = c

So the ramp is:
15.8113883008 feet

Now round the number: 
15.8ft

The above is the answer :)
(btw sorry in advance if you've spotted a mistake)

Write the equation in point-slope form of the line that passes through the given point and has the given slope (4,-7); m= -1/4
kicyunya [14]

Answer:

y + 7 = -1/4(x - 4)

General Formulas and Concepts:

<u>Algebra I</u>

Point-Slope Form: y - y₁ = m(x - x₁)  

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope

Step-by-step explanation:

<u>Step 1: Define</u>

Slope <em>m</em> = -1/4

Point (4, -7)

<u>Step 2: Write Function</u>

y + 7 = -1/4(x - 4)

I am a fraction that is equal to 1/6 what am i?
jonny [76]
We can multiply both the numerator and denominator by ANY number (as long as you multiply both the numerator and denominator by the SAME number) to get an equivalent fraction

examples would be 2/12 (numerator and denominator multiplied by 2)3/18 (by 3)
4/24 (by 4) etc.
