Answer:
hello : y =(-3/2)x+3
Step-by-step explanation:
Hello : let A(-2,6) B(4,-3)
the slope is : (YB - YA)/(XB -XA)
(-3-6)/(4+2) = -3/2
an equation is : y=ax+b a is a slope
y = (-3/2)x +b
the line through point (-2,6) : 6 = (-3/2)(-2)+b
b =3
the equation is : y =(-3/2)x+3
Let x and y be your two consecutive whole numbers
x < sqrt(142) < y
x^2 < 142 < y
So, we are looking for x and y such that x^2 < 142 and y^2 > 142.
The closest squared number to 142 is 144 = 12^2.
Next is 11^2 = 121.
11 and 12 are consecutive.
11^2 = 121 < 142 < 144 = 12^2
Thus, 11 and 12 are your numbers
Answer:
y=5/4x
Step-by-step explanation:
(A fraction)
Multiplying positive numbers always comes out positive, no matter how many there are. So you can forget about the positive ones.
Every two negative numbers in a multiplication produce a positive.
Another way to say that is: If the number of negative ones is EVEN,
the answer is positive, and if it's ODD, the answer is negative.
That monster product of eight numbers in problem #12 will be negative,
because there are an odd amount of negative factors in it.
