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.
Answer:
D
Step-by-step explanation:
They both equal 3.08
The decimal is moved one to the right on both so the answer will be the same
Answer: S(-5;3) Q(-2;2) R(-3;-2) T(-6;-1)
When reflected over the y-axis, their x values will change sign
S(5;3) Q(2;2) R(3;-2) T(6;-1)
Translate 3 units to the right, their x values will increase by 3
S(8;3) Q(5;2) R(6;-2) T(9;-1)
