Answer:
The first two pieces are 5' 5" long; the last piece is 5' 2" long.
Step-by-step explanation:
If x is the length of one of the longer pieces, then the shorter one (in inches) is x-3. The total length of the three pieces is ...
x + x + (x-3) = 192
3x = 195 . . . . . . . . . add 3
x = 65 . . . . . . . . . . inches
65 inches = 5 ft 5 inches
The first two pieces are each 5' 5" long; the remaining piece is 5' 2" long.
Answer:
2.3 * 80 + 4.7 * 70
Step-by-step explanation:
Answer:
all are answers except P(x) = 7x^2 +11x - 6 and P(x) = x^3+ x^2 + x
Step-by-step explanation:
All answers with a negative slope in the highest order polynomial will approach negative infinity as x approaches infinity. This means that all are answers except P(x) = 7x^2 +11x - 6 and P(x) = x^3+ x^2 + x
Answer:
y=-2x+5
Step-by-step explanation:
Use the equation y=mx+b
We can find the b(y-intercept) by looking at the graph
The graph crosses the y-axis at (0,5)
We can look at the slope at the graph. We can see its down 4 over 2 so the slope is -2.
Plug that into the equation y=mx+b
y=-2x+5
