Answer:
m = - 2 , c = 6
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 )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 1, 8 ) and (x₂, y₂ ) = (3, 0 )
m = 
= 
= 
= - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
using (3, 0 )
0 = - 6 + c ⇒ c = 0 + 6 = 6
im not sure this is the answer you are looking for but
45 can be 90 and 27 can be 108
27*2 is 54
27*3 is 81
27*4 is 108
Answer:
true
Step-by-step explanation:
Your question is not clear because of the grammar used. So I was only able to come up to this solution: 30/100 multiply by x gives us 18. So x= 60. The total math problems are 60. James solved 18 ( 30% of 60) now he needs to solve 70% remaining of the 60 problems. So 60 - 18 = 42.
It is already simplified. Hope this helps!
