Answer:
30%
Step-by-step explanation:
A is the answer, because the highest exponent is 2.
<u>quadratic</u>
A's expression foiled would be 2x^2 + x - 6
B's expression foiled would be 3x - 12, where the exponent on x is only 1.
D's expression foiled would be x^3 - x^2 - 12x, where the exponent on x is 3.
Answer
x=15.8
Step-by-step explanation:
20.3*2=40.6
72.2-40.6=31.6
31.6/2=15.8
(15.8*2)+(20.3*2)=72.2
20.3*2+x*2=72.2
x=15.8
Hope this helps.
Equation format for a slope, m and a point (x1, y1)
y - y1 = m(x - x1) (Try and memorize this formula)
8) for (3,-4), m = 6. x1 = 3, y1 = -4, Substituting
y - y1 = m(x - x1)
y - (-4) = 6(x - 3)
y + 4 = 6x - 18
y = 6x - 18 - 4
y = 6x - 22
10) for (-2,-7), m = 4/5. x1 = -2, y1 = -7, Substituting
y - y1 = m(x - x1)
y - (-7) = (4/5)*(x - (-2))
y + 7 = (4/5) *(x +2) 4/5 = 0.8
y + 7 = 0.8x + 1.6
y = 0.8x + 1.6-7
y = 0.8x - 6.4
y = (4/5)x - (64/10)
y = (4/5)x - (32/5)
So same approach to solve others. Cheers.
