Answer:20
Step-by-step explanation: hard to explain
Simplify 2.8y + 6 + 0.2y to 3y + 6
subtract 3y from both sides
simplify 5y - 15 - 3y to 2y - 15
add 15 to both sides
simplify 6 + 15 to 21
divide both sides by 2
switch sides
Answer: y = 21/2
*in decimal form this would be 10.5
Answer:
1/3
Step-by-step explanation:
Range=x maximum (xm) –x minimum (x0)
xm=20+20=40
Coefficient of Range= xm–x0/xm+x0
=40-20/40+20
=20/60
=2/6
=1/3
X = -1 and y = -3 ( if needed)
The Graph:
Answer:
y = x + 4
