Answer:
1.y= -2x+3 slope -2
2. y= -4/5x-6 slope -4/5
3. y= 1/3x=4 slope 1/3
4. y= x+8 slope 1
5. y= 4x slope 4
6. y= 3/2x+7 slope 3/2
7. y= 3/2x+5 slope 3/2
8. y= -1/5x-3 slope -1/5
Step-by-step explanation:
move variable to the right
change the signs
divide both sides
reorder the terms
x + 9 .
That would be the algebraic expression of "the sum of a number and 9".
28,000,000 will be the answer
Y= # of pencils
z= # of pens
1y + 1.50z = 7
Total # of pencils and pens combined equals 6
4 pencils = $4
2 pens = $3
$4 + $3 = $7
4 pencils + 2 pens = 6 items total
Divide by 60 so 105.6/60=1,76 L/min
