Answer:
B
Step-by-step explanation:
To find the slope m use any 2 ordered pairs from the table.
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 4, 11) and (x₂, y₂ ) = (2, - 1)
m =
=
= - 2 → B
Answer: Milimeters (mm)
Step-by-step explanation:
180=90+50+x
180=140+x
x=180-140=40
X=40
-3 • (5x + 2y = 7)
-15x - 6y = -21
-2x + 6y = 9
__________
-17x = -12
x = 12/17
5(12/17) + 2y = 7
2y = 7 - 60/17
2y = 3.47
y = 1.735
15% is the rate of discount
85% of 80 is 68
And 100-15= 85.
