Hey there!!
Let us take the price of the redwood as ' x ' and pine as ' y '
Then , we take it into an equation. We get,
50x + 80y = 285 -------------- ( 1 )
80x + 50y = 339 -------------- ( 2 )
Now, multiply the first equation with 8 and the second equation with 5
400x + 640y = 2280
400x + 250y = 1695
Now subtract the second equation from the first
390y = 585
y = 585 / 390
y = $1.5
Now substitute this into any equation
50x + ( 80 ) ( 1.5 ) = 285
50x + 120 = 285
50x = 165
x = 165 / 50
x = $3.3
Redwood = $3.3
Pine = $1.5
Hope helps!
The circle: x = 4 y = 0.5
The square: x = 3.5 y = 1.5
The triangle: x = 0 y = 2.5
The median and mode are the same. The low and high values are the same.
The equation would be y=32x+550. 32 an hour is represented by 32x since she earned 32 an hour. 550 is the extra amount she is getting paid.
I hope this helps.
Answer:
y=-1/2x+2
the y-intercept is at 2 and the slope is -1/2
meaning the y coordinates with move down 1 while the x coordinates will move 2 in a positive (right) direction
