Answer:
x=0.5 and y=5
Step-by-step explanation:
8x+7y=39...eqn(1)×-14
4x-14y=-68...eqn(2)×7
we now have,
-112x-98y=-546
-(28x-98y=-476)
-140x÷-140 =-70÷-140
x=0.5
to solve for y, we substitute (x=0.5) into eqn (1) or eqn 2 which ever you want...
so I'm using eqn 1.
8x+7y=39
8(0.5)+7y=39
7y=39-4
7y÷7=35÷7
y=5
therefore, x=0.5, y=5
proof: substitute both x and y values to get you the same answer as the original solutions in both equations.
we have,
8(0.5)+7(5)=39
4(0.5)-14(5)=-68

Answer:
8 Units, let me know if you didn't understand anything.
Step-by-step explanation:
Translation is the simple movement of just left, right, up or down. when dealing with the absolute value function here are the transformations.
A|B(x - C)| + D where A is the vertical stretch that multiplies all y values by A save where y=D. B is the horizontal shrink, so you divide all x values by B except for where x=C. C is the horizontal shift, which is a translation. C makes ALL points on the graph move to the right by C or if C is negative it moves them to the left. it could also look like |x + C|. keep in mind, +C is actually -C because - -C = C. D shifts up and down, so it is also a translation. if D is positive it moves up and if D is negative it moves down.
Nowthe only transformation in your problem is -8, which is a horizontal shift to the right. so the graph moves 8 to the right. There is your answer, 8 units.
