Answer:
One solution (-1,2)
Step-by-step explanation:
Since these two linear equations have different slopes, different y-intercepts, and are indeed linear, these equations will only have one crossing when graphed, and hence one solution.
To find that solution, we can simply set the equations equal to each other.
y = -x + 1
y = 2x + 4
-x + 1 = 2x + 4
-3 = 3x
-1 = x
Now plug that value back into one of the equations:
y = -x + 1
y = -(-1) + 1
y = 2
So now you know the crossing for these two equations occurs at (-1,2).
Cheers.
D) There is no association between commuting preferences and gender.
Substituting values:
= 7(3)^2(5) - 32 [wait 2=-4??? Doesn’t make sense!]
= 7*9*5-32
= 315-32
= 283
Answer:
Neither
Step-by-step explanation:
−1.3x−(−8.9x) = −1.3x + 8.9x = 7.6x
−1.3x+(−8.9x) = −1.3x −8.9x = -10.2x
Answer: Neither
Hey You!
256 / 16 = 16
16 × 11 = 176
