Answer:
AW=10
Step-by-step explanation:
In a parallelogram opposite sides are congruent meaning XA and AZ are congruent. YA and AW are congruent. So...
Solving for XA and AZ
XA=AZ
3m=5m-4
-2m=-4
m=2
If YW=10m then 10 x 2 = 20
20 divided by 2 = 10
Answer:i think it is four
Step-by-step explanation:
I am 100% sure but I hope it helps'
Its a simultaneous equation:
lets make "x" the used games and "y" the new ones
4x + 2y = 84
6x + y = 78. (multiply this by 2 to cancel out y)
12x + 2y = 156
so now we subtract them:
12x - 4x = 156 - 84
x = 9
used games cost $9
new games cost 78 - 6(9) = $24
Janet has $120 but she already bought 3 NEW games so:
120 - 3(24) = $48 left
48/9 = how many used ones she can buy = 5. something
she can buy 5 used
Answer:
There are Even, Odd and None of them and this does not depend on the degree but on the relation. An Even function: 
And Odd one: 
Step-by-step explanation:
1) Firstly let's remember the definition of Even and Odd function.
An Even function satisfies this relation:
An Odd function satisfies that:
2) <u>Since no function has been given</u>. let's choose some nonlinear functions and test with respect to their degree:
3) Then these functions are respectively even and odd, because they passed on the test for even and odd functions namely, and 
for odd functions.
Since we need to have symmetry to y axis to Even functions, and Symmetry to Odd functions, and moreover, there are cases of not even or odd functions we must test each one case by case.
Answer:
y = 10
Step-by-step explanation:
Given the 2 equations
y = - 2x + 4 → (1)
y = x² + 4x + 13 → (2)
Since both equations express y in terms of x we can equate them
x² + 4x + 3 = - 2x + 4 ( subtract - 2x + 4 from both sides )
x² + 6x + 9 = 0 ← in standard form
(x + 3)² = 0 ← in factored form
x + 3 = 0 ⇒ x = - 3 with multiplicity 2
Substitute x = - 3 into (1)
y = 6 + 4 = 10
