length, l width, w
perimeter, p = 2(l+w)...eqn 1
l = w -16...eqn 2
subst for l in eqn 2 into eqn 1...
p = 2((w-16) + w)
p = 4w -32
using p = 96, 96 = 4w -32, w = 32 inches
l = w- 16 = 16inches
Answer:
-5
Step-by-step explanation:
Answer:
Step-by-step explanation:
Take the derivative of all terms with respect to x:
-2(dy/dx) + 16x = -7 + 18y(dy/dx). Grouping the (dy/dx) terms on the left, we get:
(dy/dx)(-2 - 18y) = -7 - 16x, or
-7 - 16x
dy/dx = ------------------
-2(1 + 18y)
Substituting 2 for x and -3 for y, we obtain the desired derivative:
-7 - 16x -7 - 32 -39
dy/dx = ------------------ = --------------- = ----------- = -0.368
-2(1 + 18y) -2(1 - 54) 106
Answer:
1) y = -2/3x - 4
2) y = 4
3) y = x + 5
Step-by-step Explanation
Linear equations are represented by y= mx+b
m is your slope (the rise over the run)
b is the y-intercept (where the graph crosses the y-axis)
Answer:
√74
Step-by-step explanation:
there is no y.
wx=<8-3,-3+3,-6-1>=<5,0,-7>
|wx|=√(5²+0²+(-7)²)=√(25+49)=√74
