Answer:

Step-by-step explanation:

Y = -x -1..........(1)

y = -2x + 7....(2)

Equating the two equations

-x -1 = -2x + 7

-x + 2x = 7+1

x = 8

Putting x in (1)

y = -8 - 1

y = -9

\bold{FULL ANSWERS:}

In 1993, Moose Population: 3280

In 1999, population became: 4960

P (Population) , t (years)

t = 6 —> 4960 - 3280 = 1680

Average Change —> 1680/6 = 280 moose/year

• In terms of 1990:

t = 3 —> 3280-3 (280)

P(1990) = 2440

P(t) = 2440 + 280t

• In 2003; t = 13

P(13) = 2440 + 280 (13)
P(13) = 2440 + 3640
P(13) = 6080

• Moose population in 2003

= 6080

Schach [20]

P(0,0) and R(2b, 2c)

Midpoint:

x = (x1+x2)/2 and y=(y1+y2)/2

Midpoint PR

x = (0 + 2b)/2

= 2b/2

=b

y = (0 + 2c)/2

=2c/2

=c

Midpoint PR (b,c)

Answer is the last one

)Find the measure of angle x in the figure below: Two triangles are shown such that one triangle is inverted and they share a co
Degger [83]
So, we know that the internal angles of a triangle add up to 180 degrees, yes? 
60 degrees plus 50 degrees equals 110 degrees, and subtract 110 from 180, and you get 70 degrees for angle y.

Now, if the triangles are congruent (identical) and the shape you are describing is like an hourglass, then because of the vertical angles theorem, angle x should be 70 degrees too! 

Hope I helped!!  :)
