Answer:
yes (6,7) is a solution.
Step-by-step explanation:
(6,7) is an ordered pair, see it like (x,y). so
x=6
y=7
substitute the variable with the values.
x+y=13
6+7=13
13=13
this is a true statement.
Answer:
C
33
Step-by-step explanation:
We know that: <span>3(x-1)^2-162=0
or (x-1)</span>²= 162:3
and (x-1)²= 54
we <span>take the square root of both sides
* x-1=</span>√54= 3√6 or x=1+3√6
* x-1= -<span>√54= -3√6 or x=1-3√6
This equation has 2 solutions</span>
Answer:
Midpoint = (1,2)
Step-by-step explanation:
Using coordinates: D(-2,3) and L(4,1)
Using the midpoint formula:
Midpoint of DL = (D1 + L1) / 2, (D2 + L2) / 2
Midpoint of DL = (-2 + 4) / 2, (3 + 1) / 2
Midpoint of DL = (2) / 2, (4) / 2
Therefore the midpoint of DL is (1,2)
