Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}
You mean "four" erasers instead of "for" erasers which i corrected and solved.
Answer: You will pay 102Ghana cedis
Step-by-step explanation:
a pencil cells at 18 Ghana cedis
Three pencils will cost 3 x 18Ghana cedis=54 Ghana cedis
Also an eraser class at 12 Ghana cedis
Four erasers will cost 4 x 12 =48Ghana cedis
Total amount for three pencils and for erasers =54 Ghana cedis+48Ghana cedis=102Ghana cedis.
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 )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2points on the line
m = 
= -
Note the line crosses the y- axis at (0, 3 ) ⇒ c = 3
y = - x + 3 ← equation of line
