Answer:
slope= -2
Step-by-step explanation:
using
you plug in the values of (-2,4) and (0,0)
=
=
= -2
No, it is impossible. Intuitively, a negative number sits at the left of 0 on the number line, and a positive number sits at the right of 0 on the number line. And a number x is greater than another number y if x sits at the right of y on the number line. So, every positive number is greater than any negative number.
Also, by definition, a positive number is greater than 0, and a negative number is smaller than zero. So, if x is positive and y is negative, you have

and since the relation of order "<" is transitive, this implies

Answer:
6
Step-by-step explanation:
10² = r² + 8²
100 = r² + 64
r² = 36
r = 6
3y+4+3y-y=-6
6y-y+4=-6
5y+4=-6
5y=-10
y=-2

Answer:
A score of 117 is needed, which Is not possible since the test is over 100.
Step-by-step explanation:
The other 3 scores are 85, 94,84 . Let's x be the 4th score he must score.
Therefore ( 85 + 94 + 84 + X)/4 =95
Then 263+X /4 =95
Cross mutiplying 4*95=263+X
Therefore X= 380-263
X= 117 which is not possible since the test score is over 100.
