Answer:
Roughly 70.29 degrees
Step-by-step explanation:
Equation:
(2x+27)+(2x-11)+3x = 180
7x + 16 = 180
7x = 164
x ~ 23.43
Angle C:
3x
3（23.43)
70.29
Answer:
slope = - 1
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (2, 1)
m = 
= 
= - 1
Ok so x is the original price and we want to solve if the original price was 48 so x=48. When we substitute this into the equation we get 0.75(48)-0.15(0.75x48). When we simplify this expression we get 30.6. The current price is $30.60. Hope this helps.
-2 then -5/2 and then 1.7
Answer:
y = - 3x + 19
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 = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (6, 1) into the partial equation
1 = - 18 + c ⇒ c = 1 + 18 = 19
y = - 3x + 19 ← equation of line
