Answer:
6x - 15y = -63
15x -15y = -90
Step-by-step explanation:
We need to multiply the two equations by a constant that will eliminate the y terms.
The two equations are:
2x - 5y = -21
3x - 3y = -18
Let us multiply the first by 3 and the second by 6. The resulting equations will be:
6x - 15y = -63
15x -15y = -90
Note: To solve the system of equations we can simply subtract the first from the second.
Vertex = (3, - 2) this should be your answer. dm if im wrong
P(t)= A(1/2)^(t/h)
P(t)=10(1/2)^(16/8)
<em>(1/2)^(16/8) =.25</em>
P(t)=10(.25)
P(t)=2.5
Therefore the answer is B. 2.5mg.
Answer:
35.5 i'm pretty sure
Step-by-step explanation:
because 9 times 7 is 63. 63 plus 8 is 71 and 71/2 is 35.5
