Answer:
D
Step-by-step explanation:
you can use the slope intercept form: y = mx + b.
y = y cooordinate
m = slope
x = x coordinate
b = y intercept
the y intercept is 4.
the point (1, 7) is what we're going to use.
so the new equation is
7 = m + 4 (it would be 1m, but i rewrote it to be mathmatically correct)
subtract 4 from both sides, you should have 3 = m.
the slope is 3
Answer : The equation could you use to find p is, 
Step-by-step explanation :
Let the cost of 1 pen be, 'x'
and the cost of 1 pencil is, 'p'
As we are given that total cost of 1 pen and 1 pencil is $2.10. The equation will be:
............(1)
And we have also given that the pen costs twice as much as a pencil. The equation will be:
............(2)
Now put the equation 2 in equation 1, we get:
Thus, the equation could you use to find p is,
Try this solution:
if given dr/dt=8e^t -e^(2t), then
First of all I want to point out you drew the diagram a little wrong. The Arc is 41 doesn't mean its 41 degrees it means it has length 41 so remove the degrees symbol.
Now for the answer the other arc have to have angle 40 too because vertical angles. And because the radius is the same, both of the length has formula 40/360*pi*2*radius which is 41 in this case. So x has to be 41 also :) Done!
