Let the first number be A. and the second number B.
A + B=12-------equation1 and
A ×B =-64------eqn2
from eqn1,
A =12 - B
so put A=12-B into eqn 2
(12-B) ×B=-64
.12B-B^2=-64
B^2-12B-64=0
now use calculator to find the answer.
u will get two answers, but u haven't finished yet. if B is = X,
put Xinto A=12-B
to find the value of A.
and so the same for the second number.
Y= -2x-1 is the asnwer i think
hope this helped
Joe's dog has a mass of 28 kilograms. If you want to know about the solution, all you need to consider is this example: 1kg = 1000g. Therefore, the 28,000 gram dog is all-in-all 28 kilograms in terms of overall mass.
Answer:
<u>For the 1st graph</u>
Slope = 
Unit rate =
mi/h
<u>For the 2nd graph</u>
Slope = 
Unit rate =
mi/h=
Step-by-step explanation:
<u>For the 1st graph</u>
Slope is given as 
Rise = 
Run = 
Therefore,
Slope =
Unit rate =
= mi/h
<u>For the 2nd graph</u>
Rise = 
Run = 
Therefore,
Slope =
Unit rate =
= mi/h
Answer: the is B
