Answer:
★ = 3
✚ = 4
■ = 4
◆ = 5
Step-by-step explanation:
If we use direct correspondence in the second equation, then we have ...
◆ = 5
★ = 3
The values of ★ and ✚ in the first equation must total 7. This means ...
✚ = 7 -3 = 4
Again, using direct correspondence in the third equation, we have ...
■ = 4

<span>The square root of -16 is an imaginary number and a complex number. Sqrt(-16)=4i. We use the i to indicate that the number is imaginary since there is no number that can be multiplied by itself to get a negative number (a negative times a negative is a positive, and a positive times a positive is also a positive). So the use of i tells you immediately that it's an imaginary number. You can tell the number is complex because it has both a real and an imaginary part and could be written in the form a+bi, where a is a real number and bi is an imaginary number. In this specific case, the real part (a) is 0 and the imaginary part (bi) is 4i.</span>

To determine how much you get per hour, divide 44 by 4, 88 by 8, and 132 by 12. Each time you get 11, so you get 11 dollars an hour.
If y = money earned and x = number of hours worked, then
y=11x
because the money you get is 11 times the amount of hours you work.
Hope this helps and I can provide further explanation if needed!
