Answer:
Step-by-step explanation:
first we put them in y = mx + b form...then we compare the slopes and the y int's. In y = mx + b form, the slope is in the m position and the y int is in the b position.
2x + 2y = 8
2y = -2x + 8
y = -x + 4......slope here is -1 and y int is 4
3x + y = 8
y = -3x + 8.....slope here is -3 and y int is 8
This system has 1 solution <===
================================
learn this...it helps
* if there are different slopes and different y int, then there is 1 solution
* if there are the same slopes and different y int, then there is no solutions because u have parallel lines
* if there are same slopes and same y int, there is infinite solutions because u have the same line
Answer:
B) BC
Step-by-step explanation:
because im just right lol.
Step-by-step explanation:
p = 2×(l+w)
=> l = 3w
p = 2×(3w+w)
320 = 2× 4w
320 = 8w
=> w = 320/8 = 40
l = 3×40 = 120
so,
The width = b. ) 40 ft
The length = d.) 120 ft
