<span>Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s.
<span>Multiply both top and bottom by that number.hope this helps :)</span></span>
Answer:
19. (-∞,-5)U(-5,2)U(2,∞)
20. (-∞,-6)U(-6,4)U(4,∞)
21. (-∞,10)U(-10,3)U(3,7)U(7,∞)
Step-by-step explanation:
To summarize these three equations, ignore the numerators for every three equations listed, flip the + and - for each side to get the x values. You have to put the values from smallest to largest in order to state the domain. You need this sign -> U for the answers.
Answer:
Step-by-step explanation:
Is this graphing? If so, remember the formula: y=mx+b
If it's y=-1/3x+1, then 1 is your slope intercept
Place the dot on your graph where 1 is on your y-intercept.
Graphing -1/3x is just like rise over run, positives go up then right, (If 1/3 was graphed you would go 1 pixel up then 3 to the right.)
Since -1/3x is a negative, you're going down 1, left 3. It should give you a line that is coming from the top of the graphing box to the bottom.
If you want, create a table for x and y. If 0 was your x, then your y is 1, this is because theres a +1 in your equation.
If 3 was your x, then your y would be 0, because -1/3(3) + 1 is 0.
Given:
7 acres planted with peas and carrots.
peas represented by p. carrots represented by c.
p + c = 7
2,000 per acre of peas
1,000 per acre of carrots
goal income: 7,000
2000p + 1000c = 7000
The constraint in his system of equation would be: p + c = 7
