X-y=2  ................1
x+y=1    .........2

now by adding 1 and 2 we get,
x-y+x+y=2+1
=> 2x=3
=>x=3/2=1.5
now y=1-x=1-1.5=-0.5

The answer is D.
the base of the pyramid is lxh which is .75 x .75 = 0.5625
Each of the sides are triangles which are 1/2 bxh which equals .6/2 = .3
there is 4 triangular sides so .3 x 4 = 1.2
and 1.2 + 0.5625 = 1.7625.

For what value of t is the slope of the curve undefined for the graph defined by
ValentinkaMS [17]

Answer:

t = 0

Step-by-step explanation:

x = 10 − t²

dx/dt = -2t

y = t³ − 12t

dy/dt = 3t² − 12

dy/dx = (3t² − 12) / (-2t)

dy/dx = (12 − 3t²) / (2t)

dy/dx is undefined when the denominator equals 0.

2t = 0

t = 0

Lapatulllka [165]
<span>To put the unknown in other words, we are to determine a fraction that has a denominator of 10 which should be equivalent to 3/5. If we let x be the numerator of the second fraction such that we form a proportion out of the two fractions that is,
     3/5 = x/10
 The value of x is calculated as below,
          x = (3)(10) / 5 = 6
 ANSWER: 6</span>
