Please help me with this both for 25 points

A 20

B The constant is $4/ square ft

Step-by-step explanation:

We can find the slope of the cooking time versus weight by

m = ( y2-y1)/(x2-x1)

   = (50-30)/( 2.5-1.5)

   = 20/1

The constant is the slope which is 20

For the second problem, we also need to find the slope

We have points, (0,0) and (250,1000)

m = ( y2-y1)/(x2-x1)

 = ( 1000-0)/(250-0)

 1000/250

  4

The constant is $4/ square ft

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
