Answer: 3
Step-by-step explanation:
56 = 4
42 = x
56x = 168
x=3
What percentage was your phone at when you plugged it in?
Sometimes it helps to draw it...so u can see
7 7
J_______K_________L
|__________________|
4x - 2
since K is the midpoint, it splits the segment in 2 equal parts
JK + KL = JL
7 + 7 = 4x - 2
14 = 4x - 2
14 + 2 = 4x
16 = 4x
16/4 = x
4 = x <====
KL = 7 <===
JL = 4x - 2....4(4) - 2.....16 - 2 = 14 <==
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Isolate the variable y

Divide by -2 both sides

The solution of the inequality is the shaded area below the dashed line 
To plot the inequality find the intercepts
The y-intercept is the point (0,3) (value of y when the value of x is equal to zero)
The x-intercept is the point (-12,0) (value of x when the value of y is equal to zero)
Plot the intercepts
Drawn the dashed line
shaded the region below the dashed line
The graph in the attached figure
Correct answers should be B and C
