For this case, the first thing we must do is define variables.
We have then:
y: number of caps
x: number of shirts
We now write the system of equations that represents the problem:
The graphical solution of the system of equations (see attached image) is:
Therefore, we have 4 shirts and 4 caps.
Answer:
See attached image for the graphic
number of caps = 4
number of shirts = 4
2x + 1 = 81
2x = 80
x = 40
Answer: y = +
Step-by-step explanation:
Using the formula for finding equation of a line :
=
From the question:
X1 = 7
X2 = -1
Y1 = -4
Y2 = 2
Substituting into the formula , we have
=
⇒ =
=
4( y + 4) = -3 ( x - 7)
4y + 16 = -3x + 21
4y = - 3x + 21 - 16
4y = - 3x + 5
y = -3x/4 + 5/4
Answer:
y=-3/4x+5/4
