X -3y = -15
Subtract 'x' from each side:
-3y = -x - 15
Divide each side by -3 :
<em>y = 1/3 x + 5</em>
This is 'slope-intercept' form.
Find a number to will divide into both the numerator and denominator equally.
For example, take a look at this fraction: 10/15
What number can both divide evenly into the numerator and denominator? Well, 5!
10/15 / 5/5 = 2/3
Answer:
Step-by-step explanation:
A tree that is 100 feet tall casts a shadow that is 150 feet long ...
The angle at which the ray of the sun hit the ground is that which has a tangent equal to 100 / 150 or 2/3. This angle is equal to 33.69. Thus, the answer is letter B. 34°
