I think the trick is to add the two middle terms together. (And the 2 end terms).
8 - 12x
The variable is x. The coefficient is - 12.
8 is a constant.
The coefficient always goes with a variable.
3x^2 + 2x + 5
Nothing can be combined. The leading coefficient is 3 (which goes with the greatest power of the variable x^2 in this case) and the other coefficient is 2. 5 is a constant.
intersecting circles have two common tangents
Answer:
Step-by-step explanation:
-5x + 35 = 40
Subract 35 from both sides -5x + 35 - 35 = 40 - 35 = (-5x = 5)
Divide -5 from both sides -5x / -5 = 5 / -5 =
x = -1
Answer:
D
Step-by-step explanation:
Subtract the exponents
Answer:
Step-by-step explanation:
Slope m = 1
Point (1;8)
x1 = 1 and y1 = 8
y - y1 = m(x - x1)
y - 8 = 1(x - 1)
y - 8 = x - 1
y = x - 1 + 8
y = x + 7
