steps ?

y=3x+10, x=10 balloons

Step-by-step explanation:

The slope is 3 because for every balloon you buy, you get charged $3. The y-intercept is 10 because of the delivery fee. Substitute 40 for y and solve.

y=3x+10

40=3x+10

30=3x

x=10

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
