At a local seaside, a vendor sells single-cone ice-creams for $3 and double-cone ice-creams for $4.50. The vendor stocks a maxim

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of single cone ice cream and let y represent the number of double cone ice cream.

Since the vendor stocks a maximum of 70 single cones and a maximum of 45 double cones. hence:

0 < x ≤ 70, 0 < y ≤ 45      (1)

The vendor expects to sell no more than 50 ice creams, hence:

x + y ≤ 50

Plotting the constraint using geogebra online graphing tool, we can see that the solution to the problem is at (5, 45)

Since the vendor sells single-cone ice-creams for $3 and double-cone ice-creams for $4.50, hence:

Revenue = 3x + 4.5y

At the point (5, 45), the revenue is:

Revenue = 3(5) + 4.5(45) = $217.5

write the standard form point slope form and slope intercept form of a line that passes through (-7,6) and has a slope of. -1
TEA [102]

Answer: See explanation

Step-by-step explanation:

Point slope form: y - y₁ = m (x - x₁)

y₁ = 6

x₁ = -7

y - 6 = -1 (x - [-7])

y - 6 = -1 (x + 7)

y - 6 = -1x - 7

Add 6 to both sides

y = -1x - 1    <em>or    </em>y = -x -1

Slope intercept form: y = mx + b

m = -1

b = 6

y = -1x + 6  <em>or   </em>y = -x + 6

Standard form: Ax + By = C

Change slope intercept form into _x + _y = c

Slope intercept form: y = -x + 6

Standard form:

y = -x + 6

Add x to both sides

x + y = 6    <em>or   </em>-x - y = -6

Hope I helped!
