Answer:
The fourth graph
Step-by-step explanation:
Let x = width
The length is one less than 3 times the width, so length = 3x - 1
So we have a rectangle with length, 3x - 1, and width, x
So the area = y = (3x-1)(x)
So our equation:
y = (3x - 1)*(x)
If we check the x-intercepts, we see that y = 0 when x = 0 and 1/3. The only graph that has (0,0) and (1/3, 0) is the fourth graph, making that one our graph.
Answer: Yes! those are indeed apart of the fact family
Step-by-step explanation:
Notice that 9+5=14 and 5+9=14, thus the first two equations
show that if we add two numbers in any order, we get the same answer.
Notice that 14-9=5 and 9+5=14, so subtraction and addition are
related. Similarly 14-5=9 and 5+9=14
Notice that 14-9=5 and 14-5=9, so if you subtract one of the
members of the fact family from 14, you get the other.
Answer:
31-24x/2x-5
Step-by-step explanation:
multiply: (16-24x+15)/(2x-5)
calculate: (31-24x)/(2x-5)
write the division as a fraction: 31-24x/2x-5
Your answer would be ( -12/5 x + 2 )
