Answer:
3
Step-by-step explanation:
-5x + x + 9 = -4x + 12
-4x+9= -4x+12
move +9 to the other side
sign changes from +9 to -9
-4x+9-9= -4x+12-9
-4x= -4x+3
move -4x to the left side
sign changes from -4x to +4x
-4x+4x= -4x+4x+3
0= 0+3
0= 3
Answer: no solution
Answer:
D. -4
Step-by-step explanation:
the only graph I see is a red line in a coordinate grid.
this red line represents the function y = -4, for x in the interval [-1,4].
so, [-1,4] is the domain of the function, and [-4] is the range of the function.
when the question asks about what values are graphed below, and it mentions "range", I assume it means functional values (results of the function).
the only function I can see is the mentioned constant function y=-4, so that -4 is the only functional value (the only value in the range of the function) in this graphic.
Answer:
1.7
Step-by-step explanation:
( 5x + 2y = 7 ) 2
( - 2x + 6y = 9 ) 5
10x + 4y = 14
-10x + 30y = 45
----------------------
34y = 59
y = 1.7
You would solve this type of problem by using GCF's, greatest common factors. Since you want they all the same length and no leftovers you need a common number. The GCF is 18. Each piece will be 18 inches. You will get a total of 9 pieces
