Answer:
2m
Step-by-step explanation:
GCF of 8 and 18 is 2 and m is the only variable in both parts of the equation.
=> The first expression on the left: (1 + tan²)
we know that tangent = sin/cos
so tan² = sin²/cos²
the expression is <u>(1 + sin²/cos²)</u>
=> The second expression on the left: (1 - sin²)
we know that (sin² + cos²) = 1
subtract sin² from each side,
and we have (1 - sin²) = (<u>cos²)</u>
=> Multiply the massaged form of the two expressions:
(1 + tan²) (1 - sin²) = (<u>1 + sin²/cos²)</u> (<u>cos²)</u> = (cos² + sin²) = <em>1 </em>qed
<u> </u>
Answer:
y = 2x - 3
Step-by-step explanation:
Take any tow point from the line
(x₁ , y₁) = (1 , -1) & (x₂ , y₂) = (0 , -3)
![= \frac{-3-[-1]}{0-1}\\\\=\frac{-3+1}{-1}\\\\=\frac{-2}{-1}\\\\=2](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-3-%5B-1%5D%7D%7B0-1%7D%5C%5C%5C%5C%3D%5Cfrac%7B-3%2B1%7D%7B-1%7D%5C%5C%5C%5C%3D%5Cfrac%7B-2%7D%7B-1%7D%5C%5C%5C%5C%3D2)
m = 2 & (1, -1)
y - y₁ = m(x -x₁)
y - [-1] = 2(x - 1)
y + 1 = 2x - 2
y = 2x - 2 - 1
y = 2x - 3
Slope is rise over run which is -4/15
Hello! There are 16 ounces in a pound. To find the number of ounces in a pound, multiple 1230 x 16= 19,680. Hope this helped!
