Are you asking how to solve for k? In that case, multiply both sides by 4. Then add 3 to both sides:
(k-3) = 40
k = 43
Let P (x,y) be any point on the x-axis. Then clearly, for all position of P we shall the same ordinate 0 or, y = 0. Therefore, the equation of x-axis is y = 0. If a straight line is parallel and below to x-axis at a distance b, then its equation is y = -b.
Multiply length times width to find the area. 6.5x11= 71.5
Y=x+10
y is the total cost
x is the number of toppings times $1
10 is the cost of the pizza
