Answer:
x = 12
Step-by-step explanation:
- x/2 + 8 = 14
- Subtract 8 from both sides because it is the inverse operation of addition. x/2 = 6
- Multiply both sides by 12 because it is the inverse operation of division. x = 12
Answer:
the integer in question lies between 13 and 14.
Step-by-step explanation:
Review the perfect squares in the neighborhood of 194. The first that came to my mind was 225 (the squre of 15), and then 196 (the square of 14), and then 169, the square of 13.
Since 169 < x^2 < 196, the integer in question lies between 13 and 14.
Check with a calculator: √194 ≈ 13.93
Depth is 3.81
Step-by-step explanation:
V = l x w x d
11.43 = 2.5 x 1.2 x d
11.43 = 3 x d
÷3
3.81 = d

Step-by-step explanation:
let i be the effective rate
Answer:
d.
Step-by-step explanation:
Left line is defined when x < 1 (x is less than 1). The point is not full and that means that x = 1 is not included.
Right line is defined when x is greater or equal to one x ≥ 1.
Options that have x < 1 and x ≥ 1 are b and d, so the answer is one of those.
Equations of the lines are in slope-intercept form y = mx + b, where m is slope and b is y-intercept.
Right line has steeper slope than left line, so the slope of right line will have bigger absolute value. That is the case with option d. (Left line has slope -1 and right one has slope -2, absolute value of right slope is bigger.)
You could also check with y-intercepts. Left line has y-intercept at y = 2 and left line is defined when x < 1. Only option d meets these conditions.
