Answer:
Step-by-step explanation:
-2x-66=84+4x
collecting like terms
-2x-4x=84+66
-6x=150
divide both side by -6
-6x/-6=150/6
x=-25
Answer:
c: between 10 and 11
Step-by-step explanation:
The root of 112 is 10.58 which is between the number 10 and 11
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.
30 mph for 0.5 hrs = 15 miles
80 mph for 2 hours = 160 miles
160 +15 = 175 miles total
