Answer:
Step-by-step explanation:
Since y = -3 we can plug straight into the other equation
--> -x + 2y = -6
-x + 2(-3) = -6
-x - 6 = -6
-x = 0
x = 0
To graph this draw a horizontal like across the page at y = -3 and a vertical line down the page to represent x = 0
The point where these lines intersect is (0,-3)
So that would be the ordered pair solution.
Part 1:
A.53 =53
B.3^5/3^-6 =177147
C.(1/4)^3 • (1/4)^2 = 1
/1024
D.(-7)^5/(-7)^7 = 1/49
I tried my best for part 2 but i'm pretty sure it's not right. I think 1/1024 and 1/49 has a value between 0 and 1
Answer:
(a - 7)(3 - x)
Step-by-step explanation:
Given
3(a - 7) - x(a - 7) ← factor out (a - 7) from both terms
= (a - 7)(3 - x)
values that are <u>excluded from the domain</u> of a rational expression are values that make the denominator 0, since if that's so, the rational will be undefined. That happens when the denominator is zero out, let's do so
so, if ever m = 0, the denominator will become 0 and the rational becomes undefined, and whenever n = -3, the same will happen to the rational, thus those values are excluded.
