Answer:
4
Step-by-step explanation:
Look at the tenths place to round.
4 and below, round down.
5 and above, round up.
In this case, it’s 5 so round up.
3.50 -> 4
Answer:
5/4
Step-by-step explanation:
4y = 5x Divide by 4
y = (5/4) x
To make y = kx from y = (5/4) x
k must be (5/4)
k = 5/4
Answer:27 pieces were sold at the original price.
63 pieces were sold at the new price
Step-by-step explanation:
Let x represent the number of pieces of pottery that was sold at the original price.
Let y represent the number of pieces of pottery that was sold at the new price.
They sold some of their pottery at the original price of $9.50 for each piece. This means that the amount that they got from selling x pieces of pottery at the original price would be 9.5x
They later decreased the price of each piece by $2. This means that the new price was 9.5 - 2 = $7.5
This means that the amount that they got from selling x pieces of pottery at the new price would be 7.5y
If they sold all 90 pieces and took in $729, then the equations are
x + y = 90
9.5x + 7.5y = 729 - - - - - - - - - -1
Substituting x = 90 - y into equation 1, it becomes
9.5(90 - y) + 7.5y = 729
855 - 9.5y + 7.5y = 729
- 9.5y + 7.5y = 729 - 855
- 2y = - 126
y = - 126/- 2 = 63
Substituting y = 63 into x = 90 - y, it becomes
x = 90 - 63 = 27
Answer:
<em>An exponential function is a Mathematical function in form f (x) = ax</em><em>.</em>
<em>
</em>
Step-by-step explanation:
<em> where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.</em>
<em>NoTe</em><em>:</em><em> The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.</em>
