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).

3/8 of a fraction is the amount of water that was split
Answer:
8/125
Step-by-step explanation:
Given
red balls : 6
yellow balls : 7
green balls : 2
total balls = 6 + 7 + 2 = 15
P(red ball) = 6 / 15 = 2/5
P(3 consecutive red balls with replacement),
= (2/5) x (2/5) x (2/5)
= 8/125
Divide two corresponding sides:
GN is corresponding to AL
15 /20 = 3/4
The scale is 3/4
Answer:
C
Step-by-step explanation:
The range is the values of y that extend from the vertex downwards
The vertex = (- 2, - 1) → y = - 1
range is (- ∞, - 1 ]
