Answer:the sale of a product increases at first then decreases.
Step-by-step explanation:
Answer:
The variable t is equal to 9.
Step-by-step explanation:
We are given t • 7 = 63. To solve this for t, we divide both sides of this equation by 7, obtaining:
t = 63/7 = 9
The variable t is equal to 9.
A - area of a trapezoid;
a, b - two bases.
A = h * ( a + b ) / 2 / * 2 ( we have to multiply both sides by 2 )
2 A = h *( a + b )
2 A = h a + h b
h b = 2 A - h a
b = ( 2 A - h a ) / h
b = 2 A/h - a
Answer: D )
Answer:
the system has no solutions
Step-by-step explanation:
substract both equations and the result will be:
y - y = x - x + 2 + 1
0 = 3 is incompatible, so, no solution
