Answer: -12
Step-by-step explanation: use synthetic division
Sqrt14 = 3.74 (2dp)
The principal root is always the positive.
Answer:
-2.65
Step-by-step explanation:
-1.2 - 1.45 = -2.65
you could just simplify fraction into decimal and use calculator
Slope intercept form is y = mx + b.
Y = coordinate y.
M = Slope
X = coordinate x.
B = y-intercept.
Slope formula: (y2-y1) / (x2-x1)
Plug in: (-1 - 7) / (4 - 2) = -4.
We can just insert the pair (2,7) as our x and y to solve b.
7 = -4(2) + b.
Solve for b.
7 = -8 + b.
-b = -8 -7
-b = -15
b = 15.
Original equation:
y = mx + b
y = -4x + 15
