y=2(-3)^2+6(-3)-8 = 18-18-8 = -8
(-3, -8)
Answer:
10 i think
Step-by-step explanation:
The lines appear to be parallel. We can check this out by examining the
two equations, and we see that sure enough, both lines have the same
slope (1/2) so they're definitely parallel. Parallel lines never intersect,
so this pair of equations has NO solutions. NONE. Zero. Bubkes. Nada.
In five hours the temperature would be -13 degrees F. Hope this helps.
Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 8 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, then
y = - 3x + c ← is the partial equation
To find c substitute (2, - 1) into the partial equation
- 1 = - 6 + c ⇒ c = - 1 + 6 = 5
y = - 3x + 5 ← equation of line
