Carly’s bake shop requires 3.5 hours of labor to produce one cake and 2 hours of labor to produce one pie, and the shop has a ma
lyudmila [28]

Step-by-step explanation:

3.5 hours for 1 cake means 3.5 hours per cake.

similar : 2 hours for 1 pie means 2 hours per pie.

so, if there are e.g. 3 pies, they take 3×2 = 6 hours.

therefore the general constraint is

3.5x1 + 2x2 <= 70

I think the names "x1" and "x2" are confusing when writing this inequality.

I prefer to use x and y.

and then it would look like

3.5x + 2y <= 70

Write the polynomial equation for -1/5,-1/2,-4​
ycow [4]

Answer:

(5x+1)(2x+1)(x+4)

Step-by-step explanation:

The factored from of a polynomial can be found from the zeros or x-intercepts of the graph.

The x-intercepts here are x= -1/5, x=-1/2 and x= -4. You can find the factors by finding the expression which solves for each value.

Since x = -1/5 then the factor is 5x+1.

Since x = -1/2 then the factor is 2x+1.

Since x = -4 then the factor is x+4.

So the factored form is (5x+1)(2x+1)(x+4).
