Answer:
y=-2x+3
Step-by-step explanation:
Slope intercept form is y = mx + b where m is the slope, b is the y-intercept, and y and x are their respective coordinates.
The questions gives us a coordinate pair and a slope so all we need to find is the y-intercept to find the equation.
Begin by plugging in what we know.
(3) = (-2)(0) + b
3 = 0 + b
3 = b
Plug in the y-intercept (b) and slope (m)
y=-2x+3
Answer:
total: 3x + 7
Step-by-step explanation:
Nancy = x
Bill = 2x + 7
together = 3x + 7
This is one of those questions where, if you know the formula, it's easy,
and of you don't know the formula, there's no way.
In fact, the whole purpose of the question is to help you remember the formula.
The volume of a cylinder is
(pi) x (the radius)² x (the height).
For this particular cylinder, that's
(pi) x (3)² x (10) =
(pi) x (9) x (10) = 90 pi cubic units.
If you use (3.14) for (pi), then that's <em>282.6 cubic units</em>.
Answer:
5:6 --> 10:12
Step-by-step explanation:
A good way to think of this is to provide a perspective: there are 5 boys every time there is 6 girls. So if there is 10 boys, that means there would be 12 girls (because 5 *2 = 10 and 6*2 = 12).
tl:dr: 5 *2 = 10 so 6*2 = 12
