Answer:
Step-by-step explanation:
Let the equation of the exponential function with base 2 is,
Here, a = vertical stretch
c = Horizontal shift
d = Vertical shift
If this function has a vertical stretch by a factor of 3,
Equation will be,
If this function has a shift of 5 to the right,
Equation of the function will be,
If this function has a shift of 6 units upwards,
If the triangles are similar, then the corresponding sides are in proportion:
<em>cross multiply</em>
<em>use distributive property </em><em>a(b + c) = ab + ac</em>
<em>subtract 20x from both sides</em>
Refer to the attachment.
This is a ratio problem
4/7/1 gal = x/10.5 gal
4/7 x 10.5 = 6
1x = 6
so x is 6
