Answer:
y = - 
x + 3
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 )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 10, 17) and (x₂, y₂ ) = (5, - 4)
m = 
= 
= -
y = - x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (5, - 4), then
- 4 = - 7 + c ⇒ c = - 4 + 7 = 3
y = - x + 3 ← in slope-intercept form
The sale price would then be 25.5 dollars
Question:
Prove that:
Answer:
Proved
Step-by-step explanation:
Given
Required
Prove
Subtract tan(10) from both sides
Factorize the right hand size
Rewrite as:
Divide both sides by 
In trigonometry:
So:
can be expressed as: 
gives
In trigonometry:
So:
Because RHS = LHS
Then:
has been proven
Answer:
so for the mean u add all the numbers on there and then divide it by 5 since there are 5 numbers on there so 78+84+100+78+81=421 now we divide 421 by 5 so 421÷5= 84!
now the median would be 100? and the mode is 78 since 78 is the number that showed the most!
Answer:
{x:x>6}
Step-by-step explanation:
x-3>3
Add 3 to each side
x-3+3>3+3
x>6
{x:x>6}
