Answer:
Step-by-step explanation:
Answer is C
Answer:
y = - 4x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 4 , thus
y = - 4x + c ← is the partial equation
To find c substitute (- 4, 6) into the partial equation
6 = 16 + c ⇒ c = 6 - 16 = - 10
y = - 4x - 10 ← equation of line
For this case what we can do to represent this problem is the following rule of three:
25 feet ---> 10 inches
450 feet ---> x
Clearing the value of x we have:
x = (450/25) * (10)
x = 180 inches.
Now, let's convert this value to feet:
x = 180 * (1/12) = 15 feet
Answer:
Ella's model is 15 feet tall
Answer:
120°
Step-by-step explanation:
A line must add up to 180°.
The sum of angles in a triangle also adds up to 180°.
Step 1: Find measures interior angles.
3x = 180
x = 60°
Step 2: Find measures of exterior angels.
x + 60 = 180
x = 120°
