Answer:
y=5/4x-5
Step-by-step explanation:
Perpendicular means negative reciprocal of the slope.
y-y1=m(x-x1)
y-(-5)=5/4(x-0)
y+5=5/4(x)
y+5=5/4x
y=5/4x-5
Answer:
200
Step-by-step explanation:
C = 0.007x² − 2.8x + 100
There are two ways we can find the minimum. The first is by noticing that this is an upwards parabola, so the minimum is at the vertex. For y = ax² + bx + c, the vertex is at x = -b/(2a).
x = -(-2.8) / (2 × 0.007)
x = 200
Alternatively, we can minimize C using calculus. Take the derivative with respect to x and set to 0:
dC/dt = 0.014x − 2.8
0 = 0.014x − 2.8
x = 200
Answer:
<em>Y intercept is -2 and slope is 1 </em>the "and passes through the point
(2,4)." is irrelevant. I hope i could help. I would appreciate if you could Rate Me Brainleist.

Answer:
There is no solution.
Step-by-step explanation:
To solve, use the order of operations. Follow them until you solve for x or just numbers remain.
-(6x + 6) + 2 = -6x - 3
-6x - 6 + 2 = -6x - 3
-6x - 4 = -6x - 3
-4 = -3
The answer is no solution since this is a false statement.
