Answer:
y = -3x + 4
Step-by-step explanation:
Slope intercept form : y = mx +b
6x + 2y = 8
2y = -6x + 8
Divide the entire equation by 2

y = -3x + 4
Answer:
Below.
Step-by-step explanation:
a. 5 * 1000 = 5,000 micrometers
b. 5000 / 1000 = 5 kg
c. 4.23 * 10^12 = 4,230,000,000,000 picograms
d. 1.9 ^ 10^9 = 1,900.000,000 nanoseconds.

Answer:
x=-6
Step-by-step explanation:
2x+y=-4
5x+3y=-6
solve :
multiply first equation by 3
6x+3y=-12
5x+3y=-6
subtract the two equations : 6x+3y-5x-3y=-12-(-6)
x=-12+6
x=-6
Answer:
r≥2.5
it can't be < because the green dot is filled in
r is larger than 2.5 because the arrow goes to the right
