Since posters cost 9 dollars each and picture frames cost 15, it would be multiplication.
The expression would be 9(6)+15(6) or 9x6+15x6.
You have to multiply these numbers. 9 times 6 would be 54. 15 times 6 would be 90.
Now, we need to add these together. 54 plus 90 would be 144.
The total cost for 6 framed posters would be $144.
Any number raised to power zero = 1.
Note that 0 raised to power 0 is not 1, it is undefined.
Therefore:
(-4x)⁰ = 1
For the second part -4x⁰ = :
x⁰ = 1, -4x⁰ = -4*(1) = -4
This is true on the assumption that x is not equal to zero.
I hope this explains it.
<span>Ans : Linear functions are those whose graph is a straight line. A linear function has one independent variable and one dependent variable. The independent variable is x ( which is the distance Jacqueline travels ) dependent variable is y ( which is Speed, in mi/h )
Now the equation becomes : Speed (y) = Distance (D) / Time(X). Then the speed at which Jacqueline traveled :
y = D/X
y = 40/50 = 0.8 mi/minute
= 0.8 x 60 = 48 mi/hour.
We create a liner function and the two variables are x (Independent, Time) & y (Dependent, Speed). (D) is the coefficient of the independent variable x.</span>
