The equation f a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given the point (-3,7) and slope m=4

y-7=4(x-(-3))
y-7=4(x+3)
solve for y
y-7=4x+12
add 7 both sides
y=4x+19

Damm [24]

Answer:

\frac{80}{100} =\frac{x}{60}

then, cross multiply and the new equation is

100x=4800

finally, divide by 100 on both sides to isolate the x and you get

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 60 p
boyakko [2]

Answer:

  • large: 40 lbs
  • small: 20 lbs

Step-by-step explanation:

A system of equations can be written for the weights of the boxes based on the relationships given in the problem statement. One equation will be for the total weight of 1 large and 1 small box; the other will be for the total weight of 70 large and 60 small boxes.

Let L and S represent the weights of Large and Small boxes, respectively. The system of equations is ...

  L + S = 60 . . . . . . combined weight is 60 lbs

  70L +60S = 4000 . . . . weight of boxes in the truck

__

We can solve this by substituting for s in the second equation.

  70L +60(60 -L) = 4000

  10L = 400 . . . . . . . . . subtract 3600, simplify

  L = 40

  S = 60 -L = 20

A large box weighs 40 pounds; a small box weighs 20 pounds.
