Answer:
<h2><u>
it depends on what expression u want </u></h2>
Step-by-step explanation:
An example of a mathematical expression with a variable is 2x + 3. All variables must have a coefficient, a number that is multiplied by the variable. In the expression 2x + 3, the coefficient of x is the number 2, and it means 2 times x plus 3.
Answer:
we have the equation y = (1/2)*x + 4.
now, any equation that passes through the point (4, 6) will intersect this line, so if we have an equation f(x), we must see if:
f(4) = 6.
if f(4) = 6, then f(x) intersects the equation y = (1/2)*x + 4 in the point (4, 6).
If we want to construct f(x), an easy example can be:
f(x) = y = k*x.
such that:
6 = k*4
k = 6/4 = 3/2.
then the function
f(x) = y= (3/2)*x intersects the equation y = (1/2)*x + 4 in the point (4, 6)
First of all, how do you buy exactly 15.5 pizzas?
what is a 0.5 pizza?
anyway
cost=cost per pizza times number of pizzas
cost per pizza=10.50
number of pizzas=15.5
cost=10.50 times 15.5
cost=162.75
total cost is $162.75
