We knownthe equation of a line is y = mx + b. where m is slope and b is y intercept.
the point slope equation of a line is y - y1 = m (x - x1)
plug in x1 and y1 and m
y- (5) = (3)(x - (-1))
y - 5 = 3x + 3
y = 3x + 8
Answer:
810
Step-by-step explanation:
450 × 1.80 = 810
The 1 represents how there is no markdown and the .80 is the 80% being marked up.
I think there is a more specific equation for this than the one I showed, but this was my way of solving these questions without giving myself a headache
Surface area=5*5*6=150
volume=5*5*5=125
surface area:volume=150:125=6:5
The answer is 6:5
Answer:
19.875
Step-by-step explanation:
6y = -x - 7
<span>y= 6x - 3 </span>
<span>__________________ </span>
<span>y = x/6 + 7/6 </span>
<span>y= 6x - 3 </span>
<span>Compare the gradients, one is 1/6, one is 6. These are not parallel because they aren't the same, and not perpendicular because they aren't negative reciprocals. Therefore, neither.</span>
