Answer: 2x+4=10
Step-by-step explanation:
because each notebook would cost $3 so 2 x 3 = 6 +4=10
Answer:
y - 5 =
(x - 1)
Step-by-step explanation:
Note that
= ![m_{tangent}](https://tex.z-dn.net/?f=m_%7Btangent%7D)
Differentiate using the power rule
(a
) = na![x^{n-1}](https://tex.z-dn.net/?f=x%5E%7Bn-1%7D)
Given
y = x
= x.
=
, then
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
![x^{\frac{1}{2} }](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D)
When x = 1
=
. 1 = ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m =
and (a, b) = (1, 5), thus
y - 5 =
(x - 1) ← equation of tangent
