Answer:
Step-by-step explanation:
Notice how there are 3 -2's. With this information, we can build our factorization. Start by placing a negative two on the outside of a pair of parentheses.
-2 times what equals 
-2 times 
does. Place the in the parentheses.
-2 times positive 1x = -2x, so place that in parentheses as well. Use a plus sign in the parentheses instead of a negative sign to show that the 2x is positive. (1x is equivalent to x)
Lastly, -2 times positive one is -2, so add that in as well. Make sure you use that plus sign to show the one is positive!
And your done!
3=21/(x+5)
Cross multiply
3(x+5)=21
Divide 3
X+5 = 7
Subtract 5
X= 2
Answer:
If the price is p and the cost is c, then
15p = 20c
p/c = 20/15 = 1.333
so, he made 33% profit
Answer:
The range is [-2, 2] or -2 <= y <= 2
Step-by-step explanation:
The range are all the y-values of the graph.
If I see the graph right, the top part should be a 2 instead of a 1 and the -1 should be a -2 right?
The answer choices are not reflecting that.
I would choose All real numbers between and including -2 and 2
4 pounds times $5.89 per pound = $23.56
4x5.89=23.56
