Answer:
According to me it should be, -2x² + 12x - 7
Step-by-step explanation:
you gotta multiply "-" between two equations by the second equation which simplifies to (x² + 5x - 6) + (-3x² + 7x - 1). Now if the two equations are simplified together:
⇒ x²- 3x² = -2x²
⇒ 5x + 7x = 12x
⇒ (-6) + (-1) = -7
Putting it all in one equation will result in: -2x² + 12x - 7
Hope this helps, good luck!

Answer:
option c: angle 3 and angle 5
Step-by-step explanation:
Answer:
y = 0.6x - 3.2
Step-by-step explanation:
Parallel lines have the same slope, so in this case the parallel line will be:
y = 0.6x + b
There's b because you don't know the y-intercept yet
Then you want to substitute the point (-3, -5) since the parallel line passes through it
-5 = 0.6(-3) + b
-5 = -1.8 + b
b = -3.2
*solved for y-intercept
Answer: y = 0.6x - 3.2
Y-70
X-30
Z-80
