Answer:
1.50c +18
Step-by-step explanation:
The constant price is 18 dollars, which never changes and for every topping you get, it costs $ 1.50. Since we don't know how many extra toppings are added we write 1.50c. This shows that the price will be determined by the number of extra toppings added. If you got no toppings, sub in 0 for c to get $ 18 .
The distance from point (15,-21) to the line 5x + 2y = 4 is 27.5 units
Given the coordinate (15, -21) and the line 5x + 2y = 4
In order to get the point on the line 5x + 2y =4, we can a point on the line
Let x = 0
5(0) + 2y = 4
2y = 4
y = 2
The point (0, 2) is on the line.
Find the distance between the point (15, -21) and (0, 2) using the distance formula

Hence the distance from point (15,-21) to the line 5x + 2y = 4 is 27.5 units

Answer:
x=-2, y=-10
Step-by-step explanation:
Since both equations are equal to y, we can set them equal to each other and solve
x-8=5x
Subtract x from both sides
-8=4x
Divide both sides by 4
x=-2
Next, we need to find a y
Substitute -2 in for x in one of the equations and solve
y=5x
y=5*-2
y=-10
x=-2, y=-10
