The option A and B would be wrong since it was less than the minimum value of the function. To find the cost, you just need to replace the x variable with time after 2005.
If the time is 2025 it will be
x= 2025-2005= 20

y = 15.7x + 459
y = 15.7(20) + 459
y = 314+ 459 = $773.00

If the time is 2030 it will be
x= 2030-2005= 25

y = 15.7x + 459
y = 15.7(25) + 459
y = 392.5+ 459 =$851.50

The number of goals scored by a soccer team varies directly as the number of shots on goal. If the Lakeside Bears scored 4 goals

statuscvo [17]

Answer:

The number of additional shots on goal to score 3 more goals is 36

Step-by-step explanation:

Let

x ----> the number of goals scored

y ---> the number of shots on goal

we know that

$\frac{x}{y}=\frac{4}{48}$ ----> equation A

For x=3

substitute the value of x and solve for y

$\frac{3}{y}=\frac{4}{48}$

$y=\frac{48}{4}(3)$

$y=36$

therefore

The number of additional shots on goal to score 3 more goals is 36

3. WRITE Write a paragraph explaining the order of the steps that you would take to

polet [3.4K]

Upon first glance of an equation one must look first for parenthesis and solve the contents therein. Next one would need to identify and simplify exponents. Once these steps are well done one needs to look at the whole equation from left to right and solve for any multiplication or division problems and solve them in the order in which they appear. Next one must again look at the equation left to right and solve for any addition or subtraction in the order that they appear within the equation.
