Answer:
-1.2
Step-by-step explanation:
Given that the designer also programs a bird with a path that can be modeled by a quadratic function.
The bird starts at the vertex of the path at (0, 20) and passes through the point (10, 8).
If we treat this curve as line joining these two points then we can find the slope by the formula
Slope = change in y coordinate/change in x coordinate
Here the points given are
(0,20) and (10,8)

Slope of the line that represents the turtle's path
=-1.2
Answer:
The expression for the total cost is x = 19.99 + 0.99n .
Step-by-step explanation:
Let us assume that the total cost be x.
As given
Sophia pays $19.99 membership fee for an online music store.
If sophia purchases n songs for $0.99 each .
Than the expression becomes
Total cost = Membership fee + Cost of n songs
x = 19.99 + 0.99n
Here n represented the number of songs.
A. x= 11/5
b. x= 6
c. x= -12/2
d. x= 6/5
Simplife3^2 to 9
9x-7+2=0
9x-7+2to 9x-5
9x-5=0
add 5 to both sides 9x=5
Divide both sides by 9
x=5/9
Answer:
25%
Step-by-step explanation:
{(whole- part)/whole}*100%
(64 -48)/64 *100%= 25%
