Hey!
---------------------------------------------------------------------
We know that (a = -3), (b = 2), (c = 5), and (d = -4)
---------------------------------------------------------------------
Question 6:
= 5ac - 2b
= 5(-3)(5) - 2(2)
= 5(-15) - 4
= -75 - 4
<u>= -79</u>
---------------------------------------------------------------------
Question 7:
= ab/d
= (-3)(2)/-4
= -6/-4
<u>= 1 1/2</u>
---------------------------------------------------------------------
Hope this helped, good luck!
It should be 76.1m under water. First multiple 15x4.3=64.5, and 5.2x12=62.4. Add those together to get 126.9. Subtract that from the initial elevation of 203 and get your answer.
4(9+7) = 36+28 = 64
open the parentheses, then simplify.
Answer: Last Option

Step-by-step explanation:
The initial height of the plant of species A is 25 cm and grows 3 centimeters per month.
If m represents the number of months elapsed then the equation for the height of the plant of species A is:

For species B the initial height is 10 cm and it grows 8 cm each month
If m represents the number of months elapsed then the equation for the height of the plant of species B is:

Finally, the system of equations is:

The answer is the last option
