<span>12x = 7y-10y
12x = -3y
-4x= y
y = -4x</span>
Answer:
Step-by-step explanation:
= x²(-3 +5) +y²(2 -3) +5xy -2y
= 2x² -y² +5xy -2y
a) there are 4 terms in the simplified expression
b) 2 terms have negative coefficients (-y² and -2y)
The answer is negative two (-2)
-7 * -4 = 28, then divide 14 - 2 to the 2nd power, 14 - 2 to the 2nd power is 10, now divide, 10 by 28 and u get 2.8 then simplify and u get (-2).
Answer:
-3, -2.75, -2, 0.5, 1.55, 1.6
Step-by-step explanation:
Using the Emperical rule:
68% lie with one one standard deviation:
16 + 1.7 , 16-1.7 = 17.7, 14.3
14.3 is part of the 68%.
The remaining 32% of the distribution is outside the range, with half being less than and half being greater than.
32/2 = 16
The probability of living loner than 14.3 Would be 16%
